EFFECT OF NANOCAPSULES AND TRADITIONAL ALCOHOLIC PLANT EXTRACTS OF GRAPE SEEDS VITIS VINIFER ON CALLOSOBRUCHUS MACULATUS

The grain legumes are the second most important economic crops that attacked by many of storage pests. One of these pests is the Cowpea seed beetle (Callosobruchus maculatus). This research aims to study the effect of saponin of grape seed (Vitis vinifer) extract (1000,1500,2000,2500and 3500 ppm) on eggs and larvae. The results showed that the alcoholic extract of the seeds recorded for the egg hatching were (60, 53.33,40,33.33and16.67%) respectively, while the results recorded for Larva mortality were (23.33,26.67, 46.67, 56.67, 76.67% respectively while the highest mortality rates was 76.67% after 72 hours of treatment at a concentration of 3500 ppm. And the result showed the egg hatching that were nanocapsules 6.67% at a concentration 500 ppm and the highest Larva mortality rates were recorded at 83.33% at a concentration of 500 ppm.
