Abstract
Certain recommended chemical insecticides (Curacron, Baythroid and Larvin), Xentari (a bioinsecticide of Bacillus thuringiensis var .kurstakr), aerodendron inenne (plant extract) and Insect Growth Regulator (Mimic) were tested during 1998 & 1999 cotton growing season in Qalubia Governorate. Thirteen predaceous and five parasitoid adult species were counted, the percentages of parasitism and the damage caused by the cotton leafworm were calculated. The tested chemical insecticides caused severest effect expressed on entomophagous insects followed by Insect Growth Regulator, while both C. inerme extract and Xentari were safe for beneficial insects. The lowest rate of damage caused by S. littorals infestation to cotton leaves were (10.69 & 15.26%) in chemical insecticides opposed to (18.75 & 20.09 %) in control for 1998 & 1999 cotton seasons, respectively. The mentioned bioinsecticide or C inerme extract may be recommended, as these materials may not cause any kind of pollution on the environment
