Field studies were conducted at Shandweel Agricultural Research Station (Sohag Governorate) to evaluate the integration program which include varietal tolerancy of three cowpea cultivars (Kaha-1, Cream-7 and Dokki-126) against the infestation with E. zinckenella, also, the effect of Trichogramma evanescans, the use Neem extract and Lannate insecticides. The release of egg parasitoid T. evanescans at rat of 30.000 wasps/fed. in cawopea fawned significantly with the Neem in the infested pods and infested seeds. The %infested pods clearly decreased after application of these considered treatments with about 69.21, 75.96 and 75.13% when used Trichogramma wips, but these results in Neem about 57.50, 54.55 and 64.93%, respectively, however, the results were about 72.62, 74.18 and 73.56%, respectively when used Lannate compared with the control, in the first season. Insignificant differences in %infested pods were observed between the three cultivars. No significant differences were found in percent reduction of %infested pods, infested seeds and number of larvae/pods between cowpea plants treated with Trichogramma and those treated with Lannate insecticide. Could be recommended relesease of egg parasitoid T. evanescens to control agents against E. zinckenella. Correlation studies showed highly negative significant among percentage infected pods and seeds traits and each of number of pods/plant, weight of pods/plant, weight of seeds/plant, 100-seeds weight and dry seeds yield/fed., but, it was positive insignificant with number of branches/plant, in the both seasons.
