Avicennia marina is one of the common features of the vegetation of the littoral landscape of Red Sea, Egypt, and considers as protected area with unauthorized use of pesticides. The carob moth Ectomyelois ceratoniae(Family Pyralidae) and the mangrove plumemoth Cenoloba obliteralis(Family Tineodidae) are common herbivores on mangrove forests in Egypt. The present study aimed to search of indigenous Trichogramma  spp. within mangrove forests and also to evaluate the distribution of the three Trichogrammaspecies; T. cordubensis,T. bourarachaeandT. cacoeciae  through mangrove forests when they were released in mangrove swamps as bio-control agents. In general, releasing parasitoids allowed them to move towards the East and South directions. The distance was 3 meters where most of the released individuals prefer to move to 1 or 5 meters. T.cordubensiswas the highest potent egg parasitoid that has the ability to be released in an inundative manner to combat lepidopteran pests attacking mangrove forests in Egypt.
