Effect of Many Plant Extracts and Phenolic Compounds on Some Biological Aspects and Histological Structure on the Cowpea Weevil Ovaries Callosobruchus maculatus (Fab.) (Coleoptera: Chrysomelidae)

Analysis of High –Performance Liquid Chromatography (HPLC) for fractions of Citrullus colocynthis seeds powder ethanolic extract isolated by (CC) column chromatography showed the identification of many phenolic compounds a follows ,Cinnamic acid ,P-Hydroxy benzoic acid, Gallic acid, and Resorcinol . The P-Hydroxy benzoic acid was recorded as higher concentration in the (F8) while the Cinnamic acid was recorded as 49.23% in F7. The F8 more effective than F7 it caused mortality at 100% for both 1.5 and 2.0 concentrations. The effect of F8 of Cirullus colocynthis in concentration 0.5% caused destruction of follicular cells which appeared in different shape while the concentration 1% caused hypertrophy and disjunction of follicular cells by effect of phenolic compounds
