In vitro mass reproduction of parasitic entomophages (Braconidae, Trichogrammatidae)
Tashkent State Agrarian University, University str., 2, 100140, Tashkent, Uzbekistan
The issue of propagating parasitic insects in artificial food environments has been a challenge for researchers for a long time. Breeding one Trichogramma insect requires a lot of grain products and labor, and it takes about 40-50 days for Trichogramma and 55-60 days for Bracon to reproduce. This study aimed to develop a technology for the in vitro reproduction of trichogram, which are important parasitic entomophages in the control of various agricultural pests. The results of the experiments showed that the Trichogramma chilonis damage to nests with offspring was 82.4%, larvae emerged from eggs in 1.7 days. The larvae developed in this nutrient medium for 5.0 days, and the pupation period was 4.5 days. The average time from egg to imago was 11.2 days. The survival of hatchlings from the feeding medium lasted 5.4 days, and the male:female ratio (♂:♀) of hatched Trichograms was 1:6.
