Parasitic entomophages against plant lice in vegetable agrobioticenose

Abstract

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