Abstract

Studies on daily flight activity of certain leaf insects attacking potato, common bean and squash plants and efficiency of two types of traps in capturing them during the two successive growing seasons 1991 and 1992 were carried out at Gemmeza region, Gharbia Governorate, Egypt- During summer season, the number of Empoasca decipiens Paoli swept from potato, common bean and squash field was significanly affected by the daily time of sweeping . This factor had insignificant effect on flight activity of Myzus persicae Sulz. and Thrips rabaci Lind. The flight activity of adults of &emisia tabaci (Genn.) and E. decipiens in winter (Potato) and nili (common bean & squash) seasons was insigificantly affected during sunrise, mid-day and sunset. With regard to the efficiency of yellow sticky board and yellow pan water traps in capturing adults of Aphis craccivora Koch., M. persicae, E. decipiens, T.tabaci and B.tabaci, water trap was more efficient in trappin A. craccivora than the yellow sticky board. The opposite was true in case of the other insects.
