Citrus Blackfly
[Aleurocanthus woglumi (Ashby), family Aleyrodidae] which was introduced
from Mexico causes the most
serious damage to Texas citrus. The adult has slate-blue wings, red abdomen,
reddish eyes, and 1-2 mm in length. Eggs are laid in an unusual spiral
pattern on the leaf undersurface. This pest is best controlled biologically
by two wasp parasite species — Encarsia opulenta and Amitus hesperidum.
