| Abstract | ||||
| Field experiments were carried out at the Experimental Farm, Faculty of Agriculture, Saba Basha, Alexandria University during two succ ssive growing cotton seasons 1999 and 2000 to evaluate the side effect olthtee phe~omone Formulations and I or profenotos insecticide in special regimes on spiny bollworm Eanas insuJana (Boisd.) as non target insect. In addition the side Influence o~ the treatments were assessed on some predators. The experiments revealed the fOlloWing results: Il was round that the lowes' seasonal mean numbers of Inspected spiny bollworm Larvae (4.03, 4.42 larvae I 100 bolls) in the profenofos = insecticide treatment while It was (4.16,5.15 in T1, 5.33, 6.06 in T2 and 5 39,5.52 larvae 1100 bolls in TJ during the seasons of 1999 and 2000, respectivel ). There was no significant difference between the three cultlvars of cotton ( Giza70 , Giza88 and Giza89) . The results showed that the population densities of prevailing and common predators were about 3-7 folds in pheromone I insecticide - treated areas compared with the Insecticide treatment during the study.The highest percent values of the total inspected predators were (22.39, 21.8 and21.02)during season 1999,and (23.23. 22.51 and 23.4%) during seaso 2000 on Giza70, Giza88 and Glz.aS9 in T, (P8. Rope I curacron I seliba\e I racron ) foIlwed by 18.91, 18.76, 20.2% in TJ (selibate 1 curacronnast flight! curacron ) in season 1999; 19.01 • 18.1 and 19.0% in Season 2000 In Giza 70. Giza 88 and Giza 89 , respectively. The lowest percent values were obtained in insecticide treatment were ( 13.9,13.47 and 13.36) in season 1999; 10.29. 11.27 a d 11.29 In season 2000 on the three mentioned cUlllvars respectively. True spiders, Chrysopa spp. And Onus spp. were dominant i pheromone and I or insecticide- treated areas. The most susceptible species of predators for the insecticide application were peadrus spp .. Coccinella spp. And Scymnus spp. | ||||
