Life cycle of whitefly

whiteflies form a major threat for many vegetable and ornamental crops the adults can be recognized by their waxy wings white flies have well-developed needle-like mouth parts they extract sap from the underside of plant leaves and secrete honeydew this honeydew in turn is a nutrient source for molds the female lays her eggs on the underside of young leaves if she has not yet made it all the eggs will develop into males the eggs have a white yellowish color our oblong shaped and are often deposited in circles after one or two days they become darker in color the nymphs that emerge from the eggs are known as crawlers Crawley's move around for several hours before settling on the leaf they molt into their second stage and become immobile the nymph starts to feed and begins to produce honey due to further stages will follow the nymph now malts into its fourth stage this is the final stage before becoming an adult the nymph is flat at first later changing into an oval box shaped pupa with hers the adult emerges soon after emerging wax is secreted over the entire body adults immediately begin to penetrate the leaf with their mouthparts to feed on plant SAP check out our YouTube channel and website for more information on agricultural pests
