| Abstract | ||||
| Survey and population fluctuations of insect pests on sesame plants were carried out in Ibshwai district, Fayoum Governorate during 2008 and 2009 seasons. Eight species in five families were recorded. Population of Nesidiocoris tenuis was the highest (13089, 9772 individuals/50 double sweep < br />net) followed by Empoasca decipiens (1817, 1044 individuals/50 double sweep < br />net) and Pseudotomoscelis seriatus (529, 363 individuals/50 double sweep net) for the 1st and 2nd seasons, respectively. Three peaks were observed for N. tenius in mid of June, in the 3rd week of July, and during 2nd week of Aug. with population densities 975, 1529,2207 and in the end of June , mid July, and the beginning of Aug., with 804, 1375,1786 individuals/50 double sweep net for 1st and 2nd seasons, respectively. E. decipiens had three peaks in the 1st and 2nd seasons. Only two peaks were observed for P. seriatus in the both seasons of study. Also, it showed that these species attack often the plants through all growth stages (vegetative , flower and capsule formation stages). | ||||
