Where does whitefly come from?
If you spot adult whiteflies, particularly on older plants, then they’re likely to have emerged from an infestation of larvae and pupae on the lower leaves.
How do I control Bemisia tabaci?
Chemical pesticides are the most widely used method to control B. tabaci infestation. Chemical pesticides with a similar mode of action, such as neonicotinoids and insect growth regulators are conventional means to manage B. tabaci [14].
What type of mouthparts do whiteflies have?
Whiteflies actually are not flies; they have piercing-sucking mouthparts and are related to aphids, cicadas, and jumping plant lice. About 1200 species are known, mostly from tropical regions; about 100 of these inhabit North America. Whiteflies usually occur in groups on the underside of leaves.
What are aphids plants?
Aphids are small, soft-bodied, pear-shaped insects that cluster densely on tender new growth and the undersides of leaves to suck plant juices. Plants often can withstand some aphid feeding with no adverse effect, but badly infested plants develop distorted growth and leaves may turn yellow or drop off.
What do aphids do?

How did Bemisia argentifolii get its name?
Strain B was named Bemisia argentifolii, the silverleaf whitefly, because of its ability to cause squash silverleaf. The exact country of origin of B. argentifolii is unknown, but it is thought to be India or Pakistan as this area shows the greatest diversity in parasitoids of Bemisia, which may be an indication of a genus epicenter.
