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 seasons 1 991 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 fields was significantly affected by the daily time of sweeping, whereas this factor had insignificant effect on flight activity of both Myzus persicae Sulz and Thrips tabaci Lind. The flight activity of adults of both Bemisia tabaci (Genn.) and E. decipiens in winter (Potato) and nili (common bean and squash) seasons was insignificantly affected in 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 ., M. persicae, E. decipiens, T. tabaci and B. tabaci, water trap was more efficient in trapping A. craccivora than the sticky one. The opposite was true in case of the other insects.
