Trichogram Reproduction On Cotton Scoop Eggs In Biolaboratory

Abstract

The article discusses the issue of mass reproduction in the biological laboratory of the ovarian parasite of Lepidoptera-Trichogramma, in particular the species Trichogramma evanescens Wes, widely represented in the nature of Uzbekistan. against the dangerous pest of cotton bollworm. In Uzbekistan, much attention is paid to the use of a biological method, in particular entomophages, which, unlike the chemical method, is characterized by safety for the environment and high biological efficiency reaching 69-75%. The article describes the technology of reproduction of trichogramma in a biological laboratory on eggs natural hosts of the entomophage.

Species and population distribution of plant aphids in agrobiocenose of southeast regions of Uzbekistan

“…The productivity of orchards heavily damaged by plant aphids can decrease by 15-40%. About 5,000 species of these pests have been recorded around the world [4]. After Uzbekistan gained independence, decisions were made to ensure food security, to grow fruits and vegetables, and to increase the share, and reforms are being implemented to ensure the implementation of promising programs.…”

Significance of the family Braconidae in regulating moth population in agrobiocenosis

“…Representatives of the Braconidae family occupy a prominent place in the system of biological plant protection [1]. The parasite of caterpillars of harmful Lepidoptera Bracon (Bracon hebetor Say) is annually used in our republic against moth on an area of 1.8 million hectares and multiplies in more than 850 biological laboratories [2].…”

“…According to Kopanevani [3], among the parasitic entomophages, the Braconidae family is the most richly represented in the species composition, since about 3000 species develop on the territory of the CIS [1][2][3]6].…”

“…Also, Puttarudria and Chana Basavanna pointed out that the species Bracon hebetor and B. brevicornis do not differ in their genitalia and can interbreed, leaving fertile offspring, despite this they belong to different species [8]. Since 1956, it has been customary in India to classify existing Bracon species as Bracon hebetor [1,2,4].…”

“…Kimsanbaev [1][2][3][4] carried out deep studies on the mass reproduction of bracons in the laboratory and obtained good results. He received 4 compositions of nutritious food for breeding bracon in the biolaboratory.…”
