STUDIES ON SOME LEAF MINlNG INSECTS INFESTING CERTAIN VEGETABLE CROPS IN EGYPT

Abstract

The present study included a survey of the vegetable mining insects, associated parasitoids and predators, mining vegetation, and seasonal fluctuations of its populations under field and plastic house conditions, in addition to, prevailing the some meteorological factors, effect of different sowing dates and certain types of intercropping on populations.
