AN AGROMYZID FLY PREDACEOUS ON APHIDS

Abstract

This short note deals with the life history and habits of a beneficial insect, a fly whose maggots are predaceous on Aphids (sucking insects)-one of the worst pests of cultivated crops. Along with Hover flies (F. Syrphidae). Lady-birds (F. Coccinellidae) and Lacewings (F. Chrysopidae) these fly magpots attack aphids on a large scale and destroy them in numbers. As this insect is one the farmer should be familiar with and protect as far as possible, a short description of its various stages.
