Life Cycle of White Fly
Economic Importance: White fly infests a wide variety of crops. Nymphs and adults suck the plant's sap and spread the yellow virus and cause up to 50% damage.
Egg: The female insect lays eggs on the lower surface of the crop in rows near the mid vein. It may lay between 51 and 100 eggs in its life cycle, which may hatch within 7 to 14 days.
Nymph: Nymph infests the crops by sucking sap from the leaves. Nymphs release their exuviate 3 times at the end of their nymphal period.
Pupa: After the nymph is fully developed, it turns into a pupa in 31 days in the winter and 11 days in the summer. It takes about 7 days to become a pupa.
Adult: Adult whiteflies, after leaving the pupal case, begin to mate with female whiteflies within some time, which begin to lay eggs after two days. They live for 30 days and it continues many generations throughout the year.
For white fly control, spray Bifenthrin 10% EC @800 ml with 500 litres of water, Dimethoate 30% EC @660 ml with 750 litres of water, Dinotefuran 20% SG @125-150g with 500 litres per hectare.
Note: The quantity of insecticide dosage varies according to different crops.
