The effect of some vegetable powders of life on the permance of the Callosobruchus maculatus (Fab) (Coleoptera: chrysomelidae)

Abstract

Laboratory study was conducted to evaluate the effect of the treatment of the seeds of cowpea three types of vegetable powders (eucalyptus, oleander and watercress) in some aspects of life for South cowpea beetle C. maculatus and different concentrations (1.3, 5.7) g / g seeds, Results showed superiority powder Eucalyptus leaves morally on the rest of powders in reducing the number of eggs laid by adult reaching 27.83 egg in comparison with control, which amounted to 67.00 egg, and a higher proportion of the expulsion amounted to 58.45%, compared with less percentage of expulsion in the treatment of watercress amounted to 49.87%, the lowest number insects emerging stood at 26.7 compared with the highest number of insect insects emerging in the treatment of insect control amounted to 65.00, The highest percentage cut for members of the first generation amounted to 58.84% compared to the lowest rate in the treatment of watercress amounted to 54.17%, the lowest rate damage to the seeds of cowpea amounted to 61.66% compared to the highest proportion of damage to the seeds in the treatment of control amounted to 100%, the results showed that the highest percentage of germination of seed treatment powder Eucalyptus reached 97.33%, which was not significantly different from the rates of germination in seed treatment Bmshouka Defla and watercress, which amounted to 94.66 and 97.33%, respectively
