Indirect feeding damage: Honeydew deposition on leaves produces a shiny, sticky sheen and provides an ideal substrate for sooty mold growth. Decline in the aesthetic quality of ornamental plants in greenhouses because of honey dew, black sooty mold contamination or flying adults are problems associated with high density of whitefly populations. Disfigurement of plants in this manner by whiteflies is referred to as indirect damage as it has not resulted from physical damage caused by whitefly feeding. Outbreaks of the whitefly occur worldwide, resulting in yield loss and economic injury.
