Toxicological Sudies on Some Scale Insects Attacking Fig Trees in Egypt

Abstract

The fig has been of great importance in the early history of people about the Mediterranean. The edible fig trees, Ficus carica L. are well spread over a large area at the northern coastal region of Egypt as well as in many other localities such as in Qalubiya and Faiyum governorates. Chemical control studies were carried out at Leqada, (El-Dabaa, Matrouh governorate). This locality is charactarized by no previous chemical control measures. Results obtained from the present study revealed that, all the tested materials showed high reduction percentage (%) in the Hemiberlesia lataniae, Lepidosaphes ficus and Russellaspis pustulans population; except malathion and geer after two and three months were less efficient materials. Plastic paint was the most effective material all over the time and gave the highest rate of reduction of scale insects populations compared to other treatments.
