| Abstract |
Techniques were developed to monitor insecticide resistance in moths of the pink bollwotm Pectinophora goss piella ( Saunders). Adult stage of a susceptible laboratory pink bollworm strain were tested with six insecticides namely (Profenofos, ChlorepyTifos, Thindicarh, Carbaryl, S-fenvaLerate 5%EC. S_fenvalerate 20% EC) writ a glass vial technique to estimate concentration- mortality lines. An approzimate Lc99 was selected to discriminate for resistance in three field colony. Tests with pink bollworm moths resulted in 40- 95.7% mortality for different field colony (kafr-Elshaikh. Menoufia, and Beni- suif Governorates ) at early and late season of 2000. A formula (100-(MF/MSx 100 ) ] allowed us to determine the percentage of insects resistant in the field and simultaneously to correct for Rartiai survival of sueptibic insects at the discriminating concentration used. The methods were then tested on field- collected insects during early and late cotton season of 2000. Accuracy of the method was confirmed with another technique for measuring insecticide resistance. These techniques were developed to supplement monitoring data for adult resistance to provide timely and accurate resistance data when the insect in an actual pest and to provide producers or consualtants with a predictive bioassay useful in detecting resistance before an insecticide application.
