In: The Bulletin Faculty of Agriculture, Cairo University 2011.v.62(4)Summary: The present paper discusses the integrated control of cotton leafworm, Spodoptera littoralis and American bollworm, Helicoverpa armigera using four sprayer types i.e. (Power knapsack sprayer EFCO-16 (60 & 80) L./fed., Manual sprayer (UNX-18 100L/fed.) and conventional motor sprayer 300L/fed. Moreover, the insecticides (Dipel DF , Radical, Dursban& Consult and Dursban only) in peanut fields were tried in new Salhea region ,Sharkia Governorate. Data indicated that Radical compound gave the highest initial reduction percentage and gave the best tool of integrated control of S. littoralis and H. armigera followed by Dursban & Consult and Dursban only on peanut fields. While the lowest initial reduction percentage of S. littoralis and H. armigera recorded with Dipel OF in 2010 and 2011. On the other hand the highest mean residual reduction percentage (as a latent effect) was recorded with Radical compound in both seasons 2010 and 2011 treated by Dursban & Consult and Dursban only for S. littoralis and H. armigera. Meanwhile, the lowest mean residual reduction percentage was recorded for Dipel DF.
