Abstract
In our study, the wheat nematode Anguina tritici Chitwood, 1935 was registered in wheat ears in surveyed grain-growing farms in 5 regions of Uzbekistan. Larval stages of two- and three-year-old nematodes were observed at different stages of development in plant organs and root soil. The population density, depending on the living conditions, ranged from 8 to 60 larvae per 100 cm 3 of soil and roots, and in stems and leaves from 12 to 25 larvae per 20 g. In heavily infected ears of wheat, the number of galls ranged from 9 to 50 copies. For the effectiveness of agrotechnical measures, such as crop rotation in the fight against wheat nematode, experiments were conducted to assess the viability of wheat nematode larvae. One-year-old, two-year-old and three-year-old galls were selected and the number of larvae was counted. It turned out that the number of viable larvae in annual galls is higher than in two-year and three-year-old galls.This is due to the fact that after a period of time, the accumulated food reserves in the body were used up for the viability of the larvae.
