Abstract

The results of the study of integration between the insect antimoulting compounds like diflubenzuron and the ladybird Coccinella septempunctata (L.)  to control insects from the Black bean aphid, Aphis fabae Scopoli (Hemiptera: Aphididae). The results showed a good effect against insects Black bean aphid, Aphis fabae Scopoli. The results also revealed the existence of variation in a predation efficiency of male and female according the treatment method and Diflubenzuron concentration, the highest mean of males predation efficiency reached 52.7 ±4.7   % and for females 55.8 ±4.3 % when treating the plant leaf by Diflubenzuron concentration 0.15% respectively. The results also showed a variation in the mean mortality percentage of Coccinella septempunctata male and female and after 5 days from the treatment, highest mortality percentage in male and female were 65.4 ±3.8, 62.5 ±5.3   % respectively, when spraying at concentration of 0.5% on plant leaf with both prey and predator.
