Abstract

The present study was carried out to evaluate the efficiency of five insecticides, two oils and their combinations against cotton aphids. The results showed that carbosulfan was the most effective insecticide when was used at the recommended rate. Combinations of half the recommended rates between M.V. oil and the insecticides, malathion, pirimiphos-methyl, lambdacyhalothrin and carbosulfan produced above 90% mortality. On the other hand, monocrotophos when was combined with the M.V. oil at the above men­tioned rate produced only 82.5 % mortality. Similar findings were also observed when tar oil was mixed with pirimicarb at the same rate, how­ever, mortality was further improved when the rate of mixing was re­duced to one fourth of the recommended rate.
