| Abstract | ||||
| The red soft scale insect, Pulvinaria tenuivalvata (Newstead) is an economic important insect pest of sugarcane in Upper Egypt. The present study was conducted to evaluate the toxicity of malathion, pyriproxyfen, sulfur, bioranza, KZ. oil and sesame oil on nymphal and adult stages of P. Tenuivalvata under laboratory conditions. The obtained results revealed a wide range differences in the response of the two stages to the six tested compounds. It was obvious that, at the two levels of toxicity, the nymphal stage was most susceptible s tested insecticides while the adult stage was the most tolerant one. Malathion was the most effective compound on nymphal and adult stages of P. tenuivalvata while sesame oil was the least toxic compound. Based on the obtained results malathion, pyriproxyfen, sulfur, bioranza, kz- oil could be used in IPM program against P. tenuivalvata. | ||||
