Study of th toxicity of bean,haricot plants extraction and diazinon toxin on flour beetle insect life Tribolium castaneum (Herbst ) (Coleoptera: Tenebrionidae)

Abstract

This Study designed to examine the poisoned effect of alcoholic extraction of Vigna sinesis savi .and Phaseolas vulgaris, both plants used in concentration (2000,5000,7000,and 10000 ppm) to discover their effect on mature stages Of tribolium castananeum( herabest) after 24 and 48 hour from treatment for diazinon it has high effect in during 48hours from treasing showed adistinction for alcoholic extraction of Vigna Sinesis savi. It achieved the highest percentage of death reached (86.6%) in concentration (10000 ppm) and lowest percentage was (46.6%) in concentration (2000 ppm) while acoholic extraction of phaseolus vulgaris.achieved ahighest percentage of death accomplished 76.6% in concentration (1000)and lowest death percentage 26.3%in concentration (2000)and the diazinon had ahigh effect on death percentage reached 96,6%in concentration (90)ppm during 48 hour from treatment.
