Description of silverleaf whitefly
Distribution: Silverleaf whitefly populations persist in California's southern deserts, primarily the Imperial, Palo Verde and Coachella valleys. They also are found in the southern San Joaquin Valley, where the impact is heaviest on cotton. The silverleaf whitefly is a small plant-feeding insects with piercing-sucking mouthparts, and both immature and adult whiteflies feed on the undersides of leaves. This yellow-greenish bodied moth-like insect grows to about .8mm and has snow-white wings because of wax secretions on its body and wings. DESCRIPTION: Adults: The silverleaf whitefly is slightly smaller (about 0.96 mm in the female and 0.82 mm in the male) and slightly yellower than most other whitefly pests of flowers. The head is broad at the antennae and narrow towards the mouth parts. Description. The silverleaf whitefly, Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae), is a global pest of many economically important host plants (Simmons et al. 2008) such as eggplant, tomato, sweet potato, cucumber, garden bean (Tsai & Wang 1996), cotton, and poinsettias, to name a few. Sweetpotato whitefly damages leaves by feeding, which causes leaves to yellow and curl, and by the production of honeydew, which causes leaves to appear shiny or blackened (from sooty mold growing on the honeydew). Silverleaf whitefly (SLW) is considered a major pest of cotton due to resistance issues and the difficulty in processing lint contaminated with SLW honeydew. Scientific name Bemisia tabaci MEAM1 Silverleaf whitefly description Whitefly eggs are pear-shaped and not usually visible (0.2 mm) but deposited in circular groups on undersides of leaves, usually the youngest leaves. The eggs are anchored into a slit in the leaf surface and are initially white, changing to brown. Eggs hatch within 8–10 days. The ‘crawler’ or 1st instar
