In: Mansoura Unviersity Journal of Agricultural Sciences 2005.v.30(9)Summary: Cotton plant is liable to be attacked all over its growing season by certain sucking insects, such as cotton aphids (Aphis gossypii Colov.), cotton jassid (Empoasca Iypica de Berg), cotton whitefly (Bemisia tabaci Genn.) and cotton thrips (Thrips tabaci L.). The effect of soil and foliar applications with different rates of potassium sulfate fertilizer (48 % K₂O) was studied on the infestation of the previous insects and their associated predators, Lady-bird beetles (Coccinella spp). and Scymnus spp.), Aphid lion (Chrysoperla camea), Anthocoride bua (Orius spp.) Rove beetles (Paederus alfiernil) and true spiders which attacked Giza 89 cotton variety cultivated during 2002 and 2003 seasons at Sakha Agricultural Research Station, Kafr EI-Sheikh, Governorate Egypt.
