| Abstract | ||
| The recent experiments were conducted to classify insects attacking stored grain crops with trail to control Tribolium confusum (Jacquelin du Val) and Bruchidius incarnates (Boheman, 1833) using entomopathogenic nematodes, Heterorhabditis bacteriophora Poinar, and Steinernema feltiae Filipjev. Results indicated that stored grains under study were attacked by 11 insect species. Wheat grains were infested with nine insects where the percentages of infestation varied from 0.2% to 40%. Faba bean seeds were infested with two insects and the percentages of infestation varied from 1.5% to 50%. Rice seeds were infested with only one insect with percentages of infestation varied from 3.6- 26%. Maize seeds were infested with eight insects and the percentages of infestation varied from 0.3% to 48%. Regarding to the pathogenicity of entomopathogenic nematodes to tested insects, the results revealed that 100% mortality of T. confusum occurred with the treatments of 2000 IJs of S.feltiae & 1000, 2000 and 3000 IJs of H.bacteriophora. 100% mortality of B. incarnates obtained with the treatments of 2000 and 3000 IJs of S.feltiae & 3000 IJs of H.bacteriophora | ||
