Abstract

Sixteen insecticides and one of each mineral Oil. natural product and
insecticidal soap were tested against adults of the cotton aphid Aphis gossyp < /em>ii Glover
collected from eight Egyptian Govemorates In early 2000 cotton growing season. The
results showed that the pyrethroid Karate was the most toxic follOwed by the mineral
oil KZ-oil and the pyrethroid Meothrin then the pyrethroids Baythroid and Sumicldin,
while the carbamate Aphox and most of the organophosphorus compounds and the
insecticidal soap M.Pede were the least toxic. The natural product Neemix was less
toxic when compared with pyrethroids, but it was more toxic than OP compounds.
Compared with OP compounds, Actara, MTI-446 and Confidor were more toxic in
Lower Egypt but they were less toxic in Fayoum.
