Abstract

studied bio-efficiency for each of the parasite eggs Trichogramma chilonis (Hymenoptera, Trichogrammatidae) and larvae Bracon sp. (Hymenoptera, Braconidae) of the cotton worm spinal Earias insulana (Boisd) It was found that the egg parasitoid role in reducing the intensity of the pest eggs .And increased parasitism rate the greater the intensity of the pest eggs reaching the highest percentage of parasitism 96.5% when the density of 30 eggs of the pest and preferred females lay their eggs on the fetus advanced two and three for the modern age and the age of the egg a day،The external parasite that infects larval stage of the lesion Bracon sp. (Hymenoptera, Braconidae) show that the highest proportion of sexual parasitism rate was at education under the conditions of 20 o C and relative humidity 67 ± 3%, reaching 93.6% and 78% nationality female lives have spanned an average of 20.3 days under the same conditions.‬
