Botanical extracts of the tested plants induced histopathological damages in the integument of treated larvae represented by degeneration in the cuticle and epidermal cells and detachment from each other was also observed. Water extracts of A. monosperma, Z. cocciniem and L. termis were the most promising in inducing sever skirnkage, damages and indistinction of the fat body cells. Also mid gut show sever damage in detachment of mid gut muscle layers, as well as vacuolization takes place and degeneration of mid gut membrane and epithelial layer withdifferent degrees of effectiveness for all tested plants. This conclusion with support using support using botanical extracts in pest control programs of Lepidopterous insects.  ISSN : 1110-0583  Journal Name : Journal of the Egyptian Society of Parasitology  Volume : 40  Issue Number : 2  Publishing Year : 1431 AH 2010 AD  Article Type : Article  Added Date : Wednesday, May 23, 2012  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email نجاة علي خاطر Khatter, Najat Ali Investigator Doctorate najat.khatter4@gmail.com Files File Name Type Description  33529.pdf pdf   Back To Researches Page
