• Paraleyrodes

  nesting whiteflies, Bondar's nesting whitefly (for P. bondari), fig whitefly (for P. minei)

  Paraleyrodes is a genus of whiteflies in the subfamily Aleurodicinae, commonly known as nesting whiteflies due to the woolly wax nests constructed by females around egg masses. The genus includes economically significant invasive species such as P. bondari (Bondar's nesting whitefly) and P. minei, which are pests of coconut, citrus, fig, avocado, and ornamental plants. Species in this genus are characterized by distinctive waxy secretions, sessile nymphal stages, and polyphagous feeding habits on woody plants.

• Platynota stultana

  Omnivorous Leafroller, Omnivorous Leafroller Moth

  Platynota stultana, the omnivorous leafroller, is a highly polyphagous tortricid moth native to northwestern Mexico and the southwestern United States. It has become an established invasive pest in Hawaii, Spain, Italy, and multiple other European countries. Adults are small with wingspans around 14 mm and are active year-round in warm climates. The species completes four to six generations annually in California and produces severe economic damage in vineyards, greenhouses, and nursery operations. Larval feeding on grape berries causes skin breakage that leads to fungal rot and crop losses up to 80%.
