Abstract

The weather parameters affect aphid population. Data revealed that there is positive correlation among these variables. It is evident that as the temperature decreases humidity increases which favors the arrival of aphids. At the same time, rainfall and wind velocity exhibit negligible effect on the population of aphid. The observations further revealed that the emergence of Endaphis aphidimyza was maximum during 3 to 4 p.m. The female midges started egg laying 30 to 40 minutes after mating, preferably on the lower surface of leaves and around the stem. At the time of egg laying, the color of egg was yellowish. The process of egg laying started at 4.15 p.m. and continued up-to 6.30 p.m. The mating give rise to eggs, eventually hatching takes place and produces the larvae. The larva enter in to the stomach of the aphid and completes three stages namely first, second, third and consequently tears off the stomach of the aphid and penetrate in to the soil. Then it makes a cover for its protection to survive in the unfavorable conditions in the soil. When conditions become favorable, it comes out of the cover and mate again to produce the eggs that hatch into larvae and attack the aphids, and thus the life cycle goes on. These revelations of the lifecycle of the midge are useful in protection of the crop plants from the aphid population and thus have better harvest. In absence of Zoophagous Cecidomyiids and absence of ppm, this indicates the climatic conditions when the midges would attack and reduce the host aphid population to have aphid free crop. In the light of this fact, Zoophagous cecidomyiids is eco-friendly and crop protections insect.
