Silver leaf white flies
In light-to-moderate infestations of silverleaf whitefly, leaves show no distinctive symptoms as a result of their feeding; however, copious quantities of honeydew are deposited on leaves, resulting in a sticky, shiny appearance. Silverleaf whitefly has become a serious pest because of its high reproductive capability, wide host range, high rate of feeding, and exudation of sticky honeydew. Its feeding on squash frequently causes crop leaves to turn whitish or silver, hence the name silverleaf whitefly.
