First report of the tobamovirus Tomato brown rugose fruit virus (ToBRFV) in Turkey Since January of 2019, greenhouse-grown Solanum lycopersicum (tomato) plants in Turkey exhibited rough fruit with chlorotic and necrotic patches and leaf chlorotic mosaic, mottling, and rugosity. Molecular analyses confirmed that the causal agent was the tobamovirus Tomato brown rugose fruit virus (ToBRFV). This is the first report of ToBRFV in Turkey. ToBRFV infects S. lycopersicum and Capsicum sp. (pepper) and has also been reported from Germany, Israel, Jordan, and Mexico and has been detected in Italy. In the United States, ToBRFV has been detected in and eradicated from California. Tobamoviruses are transmitted mechanically and by seed. The PEST ID database lists ToBRFV as reportable (queried 6/5/19). References:

First report of the soft scale Alecanochiton marquesi (Hemiptera: Coccidae) in Colombia and Costa Rica with new host records In 2015, nymphs and adults of the soft scale Alecanochiton marquesi (Hemiptera: Coccidae) were collected from Manilkara zapota (sapodilla), Conostegia xalapensis, Miconia trinervia, and Miconia schlimii plants in Colombia and Costa Rica. This is the first report of A. marquesi in Colombia and Costa Rica and the first report of A. marquesi infesting these hosts. Alecanochiton marquesi infests other plants, including Coffea arabica (arabica coffee) and Pouteria caimito (abiu). Alecanochiton marquesi has also been reported from Brazil and French Guiana and is not known to occur in the United States. The PEST ID database lists A. marquesi as reportable (queried 6/5/19).

First reports of the orthotospovirus Groundnut bud necrosis orthotospovirus (GBNV) infecting Phalaenopsis sp. (moth orchid) and Momordica charantia (bitter gourd) In 2016 and 2017, cultivated Phalaenopsis sp. (moth orchid) plants in India exhibited chlorotic leaf spots, mosaic, and dark green patches with chlorotic margins. Additionally, in 2016, cultivated Momordica charantia (bitter gourd) plants in India exhibited thick, leathery, chlorotic leaves with necrotic tips and leaf cupping. Molecular analyses confirmed in each case that the causal agent was the orthotospovirus Groundnut bud necrosis orthotospovirus (GBNV) (synonym: peanut bud necrosis virus). This is the first report of GBNV infecting Phalaenopsis sp. and the first report of natural infection of M. charantia. Phalaenopsis spp. are popular ornamental orchids. GBNV causes severe yield loss in economically important plants, including Arachis hypogaea (peanut), Solanum lycopersicum (tomato), S. tuberosum (potato), Allium cepa (onion), Cucumis sativus (cucumber), and Daucus carota (carrot). GBNV has been reported from Iran, Pakistan, India, Nepal, Sri Lanka, Bangladesh, China, Thailand, Vietnam, and Indonesia. It is not known to occur in the United States. Thrips palmi (Thysanoptera: Thripidae), which has a restricted distribution in the United States, is a known vector of GBNV. The PEST ID database does not list GBNV (queried 6/5/19). References:
