ll weevil numbers in Texas at lowest level since erdication effort began.

After years of challenges, boll weevil eradication program making progress

Eradicating the boll weevil will insure that cotton will continue to be the No. 1 cash crop in the nation’s largest cotton-producing state.”

Logan Hawkes 3 | Oct 06, 2017

 

Cotton producers have a lot to worry about every year. But, one thing they aren’t worrying about as much as once they did is the dreaded Anthonomus grandis, or boll weevil, for generations the scourge of U.S. cotton farmers.

A little more than a century ago, the National Cotton Council notes, the tiny pest migrated from Mexico to the U.S., and  spread rapidly throughout the cotton belt. Over subsequent decades, it has cost America’s cotton producers more than $15 billion in yield losses and control costs.

In 1958, the council officially recognized the economic havoc the pest represented for U.S. cotton production, and with congressional support, a USDA Boll Weevil Research Laboratory was created, followed by eradication experiments, a trial eradication program, and an area-wide boll weevil control program implemented in the Texas High Plains and Rolling Plains to halt the weevil’s migration northward out of Mexico.

Based upon the results of those efforts, in the 1970s a boll weevil eradication program was launched by USDA’s Animal and Plant Health Inspection Service (APHIS), beginning with eastern seaboard states. Not long afterward, several state boll weevil groups were founded, including the Texas Boll Weevil Foundation, Inc.

ON THE FRONT LINE

Texas has long been on the front line of eradication efforts because of the common border it shares with Mexico. Boll weevil problems across the Rio Grande have been a serious issue, including potential for migration of the pest — mostly carried by wind — and sporadic outbreaks that have been problematic in parts of Texas, especially along the border corridor.

Much like other issues in the cotton industry, 2017 has had its share of challenges for the boll weevil eradication program, says Foundation President and Chief Executive Officer Lindy Patton. But in spite of huge increases in cotton acres, weevil reinfestations into eradicated areas, and plenty of weather-related obstacles, such as Hurricane Harvey, the Texas boll weevil eradication program made excellent progress toward eliminating the dreaded pest.

Things haven’t always been smooth, however. After decades of successful eradication efforts, occasional weevil outbreaks have largely been limited to deep south Texas. But in 2015, a troubling trend seemed to be developing. It was a very wet year in the Lower Rio Grande valley and across the border in Mexico’s Tamaulipas State. Trapping and treatment efforts in the Valley were troubled, especially considering the large migration of weevils from Mexico.

Eradication officials in Mexico said they were experiencing problems in addition to heavy rains. They included funding to conduct control methods, and involuntary cotton that was increasing as homeowners planted cotton seeds and nurtured their year-round development into tall plants, and even tree-size plants for shade. Weevil populations exploded.

In Texas, the fight was on to prevent migration of the pest further north into the state. Despite foundation efforts, weevil captures in early 2016 totaled 15,705 weevils in the Winter Garden area, with a few trapped near Alice.

COOPERATIVE EFFORT

“But things began to improve for the eradication effort in 2016,” Patton says. “Texas and Tamaulipas growers, along with program personnel from both nations, have worked to together to make both programs more effective. Changes to the eradication program in Tamaulipas greatly reduced migration, and the foundation started to get a handle on the weevil problem.”

Thanks to the Texas Boll Weevil Eradication Foundation, with assistance from other agencies like USDA and the North American Plant Protection Organization, help was offered to Mexico with both trapping and treatment programs, as well as identifying voluntary cotton and its removal. By late 2016, the boll weevil problem was improving across the border in Mexico, and in Texas.

Thus far in 2017, weevils were found only in two areas of Texas, the Winter Garden area around Uvalde, and in the Lower Rio Grande Valley. A total of 1,022 weevils have been captured in the Winter Garden area. The good news is that 747 of those were captured in the first two weeks of the year, with only 275 trapped the rest of the growing season. Strong cooperation from area farmers, and diligent work on the part of foundation personnel, are being credited for that success.

“So far in 2017, the eradication program has been able to bring weevil numbers to their lowest level since the program began,” Patton says. “Fewer than 30,000 weevils were trapped through the end of September, on nearly 200,000 planted acres of cotton.”

Program Director Larry Smith says he is extremely proud of the progress made. “Our program personnel have worked extremely hard, and have done an amazing job of bringing weevil numbers down to these record low levels. Many cotton producers in the Lower Rio Grande Valley have taken ownership of this important program, and have encouraged their neighbors to be diligent in destroying cotton stalks and volunteer cotton.”

He emphasizes that producers and the eradication program must work together to finish the job. “The last weevils are the hardest to get rid of, and we must work together to find and eliminate all volunteer cotton, destroy stalks in a timely fashion, and encourage folks to help by not planting cotton in difficult-to-treat places.”

With the weevil eradicated from over 98 percent of the state’s cotton fields, Patton says, the farmer-run Texas Foundation is helping producers achieve some amazing yields, and survive in some really tough times. Eradicating the boll weevil will insure that cotton will continue to be the No. 1 cash crop in the nation’s largest cotton-producing state.”

Brazil’s transgenic sugarcane stirs up controversy

  •  Sugarcane borer causes losses of around US$ 1.5 billion per year
  • Experts warn of lack of environmental impact studies in Brazil
  • Damage to biodiversity, including non-target insects, is among potential risks
 
[RIO DE JANEIRO] A genetically modified (GM) cane variety that can kill the sugarcane borer (Diatraea saccharalis) has been approved in Brazil,  to the delight of some scientists and the dismay of others, who say it may threaten Brazilian biodiversity.

Brazil is the second country, after Indonesia, to approve the commercial cultivation of GM sugarcane. The approval was announced by the Brazilian National Biosafety Technical Commission (CTNBio) on June 8.

Sugarcane borer is one of the main pests of the sugarcane fields of South-Central Brazil, causing losses of approximately US$1.5 billion per year.

“Breeding programmes could not produce plants resistant to this pest, and the existing chemical controls are both not effective and severely damaging to the environment,” says Adriana Hemerly, a professor at the Federal University of Rio de Janeiro, in an interview with SciDev.Net.

“Studies conducted outside Brazil prove that protein from genetically modified organisms harms non-target insects, soil fauna and microorganisms.”

Rogério Magalhães

“Therefore, the [GM variety] is a biotechnological tool that helps solve a problem that other technologies could not, and its commercial application will certainly have a positive impact on the productivity of sugarcane in the country.”

Jesus Aparecido Ferro, a member of CTNBio and professor at the Paulista Júlio de Mesquita Filho State University, believes the move followed a thorough debate that began in December 2015 — that was when the Canavieira Technology Center (Sugarcane Research Center) asked for approval to commercially cultivate the GM sugarcane variety.

“The data does not provide evidence that the cane variety has a potential to harm the environment or human or animal health,” Ferro told SciDev.Net.

To develop the variety, scientists inserted the gene for a toxin [Cry] from the bacterium Bacillus thuringiensis (Bt) into the sugarcane genome, so it could produce its own insecticide against some insects’ larvae.

This is a technology that “has been in use for 20 years and is very safe”, says Aníbal Eugênio Vercesi, another member of the CTNBio, and a professor at the State University of Campinas.

But Valério De Patta Pillar, also a member of the CTNBio and a professor at the Federal University of Rio Grande do Sul, points to deficiencies in environmental risk assessment studies for the GM variety — and the absence of assessments of how consuming it might affect humans and animals.

According to Pillar, there is a lack of data about the frequency with which it breeds with wild varieties. Data is also missing on issues such as the techniques used to create the GM variety and the effects of its widespread use.

Rogério Magalhães, an environmental analyst at Brazil’s Ministry of the Environment, also expressed concern about the approval of the commercial transgenic cane.

“I understand that studies related to the impacts that genetically modified sugarcane might have on Brazilian biodiversity were not done by the company that owns the technology,” said Magalhães in an interview with SciDev.Net. This is very important because Brazil’s climate, species, and soils differ from locations where studies might have taken place, he explained.

Among the risks that Magalhães identified is contamination of the GM variety’s wild relatives. “The wild relative, when contaminated with transgenic sugarcane, will have a competitive advantage over other uncontaminated individuals, as it will exhibit resistance to insect-plague that others will not have,” he explained.

Another risk that Magalhães warns about is damage to biodiversity. “Studies conducted outside Brazil prove that Cry protein from genetically modified organisms harms non-target insects, soil fauna and microorganisms.”

Magalhães added that some pests have already developed resistance to the Bt Cry protein, prompting farmers to apply agrochemicals that are harmful to the environment and human health.

It started with a simple move to change the tax code so that farmers could keep more of the value of their cocoa crop.
By Chris Arsenault, Thomson Reuters Foundation

NOVEMBER 17, 2014

ROME — As India starts its version of Brazil’s famous zero hunger campaign, the world’s most populous democracy could take some inspiration from Ghana.

The West African country “has met zero hunger,” Jose Graziano da Silva, head of the Food and Agriculture Organization said last month.

Former Ghanaian president John Kufuor can take at least some of the credit for this.

It started with a simple move to change the tax code when Kufuor’s government first took office in 2001.

Taxes on cocoa, a key export crop, stood at 60 percent of the market price, so growers could keep only 40 percent of the value of their production.

“We reversed this, giving the farmers 60 percent of the profits,” Kufuor said in an interview with the Thomson Reuters Foundation. “The state had been over-taxing the farmer.

“Farmers needed chemicals for fighting pests and fertilizers, the government paid for this.”

The investment paid off, and cocoa production doubled within four years, sending more money into state coffers for infrastructure investment.

The government then turned its attention to trying to mitigate deforestation. In 1960, more than 60 percent of the country was covered in forest but deforestation has decreased coverage to 21.7 percent today.

The state allowed landless families and unemployed people to use land where the forests had been cut, to plant crops interspersed with new trees in what became known as the Modified Taunga System.

After getting training from the state, local residents were able to earn an income when the trees were harvested, preventing additional land from being logged and improving food security for some of Ghana’s most vulnerable citizens.

Finally, the country tried to move up the value chain for its cocoa production.

“Chocolate, which is loved internationally, especially by the ladies, wasn’t part of our traditional diet,” Kufuor said. “The beans were exported.

“We saw the need to attract top quality processors to Ghana.”

Some large multinational confectionery companies moved in and set up factories, though the country still exports more raw beans than refined chocolate.

“The objective is to add value locally so 70 percent of the cocoa is processed and only 30 percent is exported [raw]. We are moving towards this,” Kufuor said.

Ghana’s per capita GDP shot up to $1,300 in 2007 from $400 in 2001, thanks largely to growth in the agriculture sector, high commodity prices, and the discovery of oil, which allowed it to reach lower middle income status and meet the Millennium Development Goals on poverty reduction ahead of schedule.

“One of the key factors [in Ghana’s success] has been strong political commitment at the highest level,” FAO Ghana representative Lamourdia Thiombiano said in an interview with the Thomson Reuters Foundation.

“They subsidized production, put resources into boosting capacity, and invested in providing services to farmers.”

“More production led to relatively better access to food,” Thiombiano said.

Significant development challenges remain, despite the improvements in agriculture, and Ghana ranked 138 out of 187 countries surveyed in the U.N. 2014 Human Development Report.

Today Kufuor, who gives speeches on the U.N. circuit and runs his own foundation, is optimistic that “rays of hope” and good policies will continue to improve food security in a world where 1 in 8 people still suffer from chronic malnutrition.

-The draft SDGs ignore biodiversity’s effect on food, health and poverty

-A holistic approach is critical, UN meeting hears

-Participants pledge to double biodiversity-related funding for poorer nations

Biodiversity is moving up the global development agenda, following a major meeting of policymakers at the 12th Conference of Parties (COP12) to the UN Convention on Biological Diversity (CBD) in Pyeongchang, South Korea.

With countries working on setting the next targets after the Millennium Development Goals, biodiversity is already included as one of the proposed 17 Sustainable Development Goals (SDGs) in the UN draft working document agreed in July.

However, the current draft does not acknowledge biodiversity’s effects on global issues such as health, poverty and food security.

These effects took centre stage at the event in Pyeongchang, which was attended by around 3,000 delegates from 6-17 October.

“If we tackle poverty, inequality and environmental issues in separate silos, we can’t succeed. We have to have holistic approaches,” said UN Development Programme boss Helen Clark.

Braulio Ferreira de Souza Dias, executive secretary of the CBD, told environment ministers and other delegates that its 2010 biodiversity plan was critical. “We will not be able to achieve sustainable development if we do not implement the Strategic Plan for Biodiversity,” he said.

The plan estimated that US$150-440 billion a year was needed in biodiversity-related financial flows to reverse species and habitat loss, compared with the US$50 billion a year in 2010 being spent worldwide.

At the beginning of the COP12 event, the UN released a report showing progress was lagging on biodiversity goals known as Aichi targets set out in the CBD’s 2010 biodiversity plan.

For example, the key target of halving the rate of biodiversity loss, backed by a US$2.2 billion fund created at the 2010 COP meeting in Nagoya, Japan, is nowhere near being reached, according to projections in the Global Biodiversity Outlook 4 (GBO4) report.

Habitat loss

At a separate high-level meeting that took place on 16 and 17 October, ministers of the environment signed the so-called Gangwon declaration, pledging to double biodiversity-related funding for developing countries and maintain this level until 2020 to reach the Aichi biodiversity conservation targets.

Despite opposition from some larger developing countries, including India and Brazil, which cited budget constraints and the need to hold richer countries to their funding commitments, the meeting agreed that signatories should “mobilise domestic resources”. This breakthrough clause, unusual in UN documents, will mean that national budgets should give more priority to biodiversity issues.

Other areas falling well short included stemming species loss, habitat destruction, overfishing and pollution. And it seems that such declines as well as pressures on habitats are only growing, said Derek Tittensor, senior marine biodiversity scientist at the UN Environment Programme. “We’re making some effort, but, at the moment, we’re not seeing the benefits,” he told SciDev.Net.

“There has been an increase in resources and that is projected to continue into the future — that’s partly what has come out of the COP12 meeting in Korea — but the big question is whether that will be sufficient to arrest the decline in the state of biodiversity that we observed and projected,” he added.

Others, however, were more optimistic. GBO4 “is just a starting point”, said Anne-Hélène Prieur-Richard, acting executive director of international biodiversity research programme DIVERSITAS. “Some of the targets are very far from being able to be achieved by 2020. However, we also know there are lags between the time of starting actions on the ground and the time you get the fruits of them,” she told SciDev.Net.

‘Pyeongchang road map’

“It is my strong belief that these decisions will enable us to turn many of the indicators in GBO4 from yellow to green.”

Braulio Ferreira de Souza Dias, CBD In total, the meeting adopted 33 decisions referred to collectively as the ‘Pyeongchang road map’.

Among the decisions was an agreement to establish a technical expert group to examine how synthetic biology products should be regulated. COP12 agreed that risk assessment and regulations must tally with the ‘no-harm principle’ that activities avoid damaging the environment of other states or areas beyond the limits of national jurisdiction.

But the highlight of the meeting, according to delegates, was the entering into force of a treaty signed four years ago that opens up access to genetic resources and a mandatory fair sharing of the benefits derived from them.

The Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits arising from their utilisation to the CBD came into force on 12 October after the 50th ratification.

Research findings should reduce trade barriers and boost pest control measures

28 October 2014, Rome/Vienna – Four of the world’s most destructive agricultural pests are actually one and the same fruit fly, according to the results of a global research effort released today. The discovery should lead to the easing of certain international trade restrictions and also aid efforts to combat the ability of these harmful insects to reproduce, experts said.

The so-called Oriental, Philippine, Invasive and Asian Papaya fruit flies, the study shows, all belong to the same biological species, Bactrocera dorsalis, which is causing incalculable damage to horticultural industries and food security across Asia, Africa, and the Pacific.

The international collaborative effort, involving close to 50 researchers from 20 countries, began in 2009 and was coordinated by FAO and the International Atomic Energy Agency (IAEA). It followed an integrative approach, examining evidence across a range of disciplines.

The ability to precisely identify pests is central to pest management, including quarantine measures or bans applied to internationally traded food and agriculture products such as fruit and vegetables.

Keeping exotic fruit flies out is a major concern for many countries. The study’s findings mean that trade restrictions linked to the Oriental fruit fly should now fall away in cases where the insect is present in both the importing and exporting country, according to Jorge Hendrichs from the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture in Vienna.

“This outcome has major implications for global plant biosecurity, especially for developing countries in Africa and Asia,” said the study’s lead author, Mark Schutze, from the Plant Biosecurity Cooperative Research Centre (PBCRC) and the Queensland University of Technology (QUT).

“For example, the Invasive –now Oriental — fruit fly has devastated African fruit production with crop losses exceeding 80 percent and has led to widespread trade restrictions with refusal of shipments of products into Asia, Europe and Japan, and significant economic and social impacts on farming communities,” Schutze added.

Using sterilized males to mate with wild females

The findings of the study will also simplify techniques like the use of sterilized males to prevent the growth of pest populations.

A form of insect birth control, the sterile insect technique involves releasing mass-bred male flies that have been sterilized by low doses of radiation into infested areas, where they mate with wild females. These do not produce offspring and, as a result, the technique can suppress, if applied systematically on an area-wide basis, populations of wild flies in an environmentally friendly way. The FAO/IAEA Agriculture and Biotechnology Laboratories have demonstrated that the four fruit flies freely interbreed, which means that instead of using males from the four supposedly different species, mass-produced sterile Oriental fruit fly males can now be used against all the different populations of this major pest.

“Globally, accepting these four pests as a single species will lead to reduced barriers to international trade, improved pest management, facilitated transboundary international cooperation, more effective quarantine measures, the wider application of established post-harvest treatments, improved fundamental research and, most importantly, enhanced food security for some of the world’s poorest nations,” Schutze said.

The findings of the FAO/IAEA coordinated study, published in the journal Systematic Entomology means that the four, previously considered distinct fruit-fly species, will now be combined under the single name: Bactrocera dorsalis, the Oriental fruit fly.

A BEACON IN THE SMOG

So far the EPA has refused to ban use of neonicotinoid insecticides — despite mounting evidence that they kill bees and other wildlife, despite a ban in the European Union, despite a lawsuit filed by activists and beekeepers.

But if the EPA is somehow still unclear on the dangers posed by neonics, it need only talk to the official who oversees federal wildlife refuges in the Pacific Northwest and Pacific Ocean.

Kevin Foerster, a regional boss with the National Wildlife Refuge System, directed his staff this month to investigate where neonics are being used in the refuges they manage — and to put an end to their use. Foerster’s office is worried that farming contractors that grow grasses and other forage crops for wildlife and corn and other grains for human consumption on refuge lands are using neonic pesticides and neonic-treated seeds. There are also fears that agency staff are inadvertently using plants treated with the poisons in restoration projects.

“The Pacific Region will begin a phased approach to eliminate the use of neonicotinoid insecticides (by any method) to grow agricultural crops for wildlife on National Wildlife Refuge System lands, effective immediately,” Forster wrote in a July 9 memo that was obtained and published last week by the nonprofit Center for Food Safety. “Though there will be some flexibility during the transition and we will take into account the availability of non-treated seed, Refuge managers are asked to exhaust all alternatives before allowing the use of neonicotinoids on National Wildlife Refuge System Lands in 2015.”

An information sheet attached to the memo notes that “severe declines in bee fauna have been a driving force behind the growing concern with neonics,” but that other species are also being affected. The information sheet also warns that pesticide drift, leaching, and water runoff can push neonics into wildlife habitats near farmed lands.

The use of the pesticides in U.S. wildlife refuges has triggered outcries and lawsuits from groups that include the Center for Food Safety. “Federal wildlife refuges were established to protect natural diversity,” said Paige Tomaselli, an attorney with the center. “Allowing chemical companies to profit by poisoning these important ecosystems violates their fundamental purpose and mission.”

Foerster’s move will help protect nearly 9,000 acres of refuges in Washington, Oregon, Idaho, Hawaii, and the Pacific Islands from ecosystem-ravaging poisons.

But the memo has significance beyond that. It confirms that wildlife experts within the federal government are acutely aware of the dangers that the poisons pose. Now we just need the U.S. Fish & Wildlife Service and the EPA to talk to each other.
