Abstract The negative impact of pests on world agriculture is estimated at 1.4 trillion dollars, which 5% the global gross domestic product. In order to save crops lost due agricultural in world, it urgent importance develop effective and fundamentally based control measures against them. this research, main studied were Aphis craccovora Koch; gossypii Glow; Brevicoryne brassicae, Lysiphlebus fabarum Marsch, parasitic entomophages Rhopalosiphum nymphaeae sucking pests. It was found that worm infects plant juices average 79.6 + 0.03. parasite developed type aphids lived for 7.1+0.02 days, sex ratio 1:5 (♂:♀). When mummified swollen examined infection with parasite, degree damage host’s offspring 67.2%.
