Biological Activity of some Control Agents and Trichogramma evanescence on the Bioactive of Batrachedra amydraula M. (Batrachedridae:Lepidoptera) on Date Palms in Iraq

Abstract Field studies were conducted in each of the governorates Basra, Maysan and Dhi Qar Babylon included a field survey for presence bug Batrachedra amydraula sensitivity some date palm cultivars to infection mentioned insect evaluating efficiency direct spraying different concentrations control agents reducing rates with on immature fruits palm, Where nano silver (AgNPs), Alsystin, Trichoderma viride , Trichogramma evanescence used. Whereas, treatment province Basra recorded highest percentage B. amounted 53.79%. While lowest was Qar, it 43.66%. The cultivar Al-Zuhdi also by 51.29%, Al-Halawi rate 44.66%. Whereas most effective among all other factors. bitch reduced 6.00% compared treatment, which 55.03%, while biological fungus T. had least effect total 18.40% gave 55.03%. interaction between growth regulator cysteine contributed higher reduction an average 5.60%, combination bio Alsystin 29.70%. egg parasitoid effectively infestation influencing eggs presence, where (3 capsules/palm) at 6.54% (1capsule/palm) rates, 11.87%, 55.03% rates.
