Prelimenry study about the insecticides efficiency in controlling Autumn generation of Date Palm Dubas bug Ommatissus binotatus De Bergevin (Homoptera: Trobiduchidae)

journal of kerbala university, 2008, Volume 4, Issue 1, Pages 73-78

This study was carried in Date Palm orchard at Snieja / Diyala,80 KM North- East of Baghdad. Using new insecticides{Phosalone[Zolone300ULV],Deltamethrin[Decis12.5 ULV], pyridaphenthion [Ofunack25ULV], phenthoat [Phenthold 92ulv] and Etofenprox [Trebon 7.5ULV]}. USING Agricultural helicopter,type Mi-2in spraying by Micronair AU 5000 atomizerwith average 2L/Ha. the treatments distributed according to Randomized Complete Design [CRD] in addition to control treatment [water only], treatment area [12Ha]. infestation severity has been calculated one day before application and 1,3,5,7 & 10 day after spraying by taking samples from Date Palm leaflets or 150 leaflet / treatment. Killing percentage has been calculated according to Henderson - Telton equation. Result showed that all insecticides had high efficiency but Etofenprox was the best, the killing percentage was 94.72 & 91.76 in the 1st & 2nd year respectively. The application of spraying in autumn followed by spring generation caused high mortality, the average number of population density was reached to 1.03 insect / leaflet compared with 6.42 insect / leaflet in spring generation only.
