Pathogen name: Cucumber mosaic virus (CMV)
Host crops: Numerous plant species (>300) can be infected with CMV. The virus is vectored by a number of aphids. CMV also can be seedborne and seed transmitted in pepper.

Common name: Broad mites are tiny (0.2 mm-long adult females), oval, light yellow to amber or white or even green arachnids (so they have eight legs). Male adults are smaller. There are four life stages: egg, larva, nymph and adult. Eggs are colorless, translucent, elliptical, about 0.08 mm long, and covered with white tufts on the upper surface. Young broad mites have only three pairs of legs, are slow moving, and whitish in color. The quiescent stage is an immobile, engorged larva. Injury to broad mites can be difficult to diagnose because of how small the pests are and the locations where they feed on plants. Broad mites typically feed within growing meristems and require magnification to be seen.
Latin binomial: Polyphagotarsonemus latus (Arachnida: Acari: Tarsonemidae)
Host crops: Broad mites have a wide host range in tropical areas and commonly infect plants in greenhouses in temperate and subtropical areas. Hosts include many perennial and annual plant species, including ornamentals, citrus, grape, and vegetables such as bean, cucurbits, eggplant, tomato, pepper, potato, etc. Adults feed on the lower surface of leaves and on fruit.
