| Abstract | ||
| The present study has been conducted in Shaat_al-Areb area of Basra governorate during the cultivation season of 2014 to evaluate the effect of some bio insecticides including Oxymatrine, Bacillus thuringiensis and Trichoderma harzianum , as well as , the parasitoid Bracon hebetor . Results revealed the strong effect of Oxymatrine, Bacillus thuringiensis and Trichoderma harzianum on both the larvae of lesser moth and the adults of parasitoid with averages of mortality 97.6% and 96.1% , respectively, while. The lowest percentages of mortality were observed 42.6% and 8.5% the larvae of the lesser moth and adults of parasitoid B. hebetor Field trail explained the synergistic effect of the combination between the parasitoid and insecticides in reducing the infestation percentage of date palm by lesser moth insect; the lowest percentage was recorded at the treatment of oxymatrin and the parasitoid B. hebetor on date palm fruits, compared with 10.3% of control treatmen̓t the lowest fruit drop percentage was 11.5% at the treatment of oxymatrin and parasitoid compared to control treatment which was 24.5% . | ||
