WHITEFLY
Whitefly (Bemisia tabaci) is a plant sap-feeding insect which belongs to the order Homoptera, is a global pest causing significant loss to a wide variety of agricultural commodities. Whiteflies are not true flies. It is related to aphids, scales, and mealybugs. Whiteflies cause damage to plants in two ways. Such as by sucking the sap and transmitting viral disease. Furthermore, they secrete honeydew onto leaves where black sooty mold can grow. They have become one of the most severe crop protection problems.
Whitefly Life Cycle
At 70ºF, the greenhouse whitefly life cycle takes: 6-10 days for egg hatch, 3-4 days as a nymph I, 4-5 days as nymph II, 4-5 days as nymph III, 6-10 days for the pupa. Adults can live for 30 to 40 days.
Whiteflies have a characteristic life cycle with six stages: the egg, four immature stages (nymphal instars), and the adult stage. The main factors that significantly influence the life cycle of whitefly species are temperature, relative humidity, and host plants. Whiteflies usually lay their tiny eggs on the undersides and upper side of leaves. Then eggs hatch. Hatching occurs after 5 – 9 days at 30°C. Then young whiteflies gradually increase in size through four nymphal stages called instars.
