Aphides of Crop Husbandry
Studies on Research İnstitutedamageability of wheat variety samples were
conducted in 2014 and 2015 on wheat sowings in Absherones and Terter RES.
We
have studied the distribution, density, the nature of damage and losses
from aphides. Aphides in these areas is a
constant pest of cereal crops, but their
harmfulness is periodic.
In 2014 and 2015 years, optimal weather condition
in vegetation period
influenced development of the larvae of Aphides. Their number was more 50 ekz.
Larvae per 1 spike, resulting in much damage to variety samples of wheat.
Selected the most weakly damaged variety samples as initial material for
breeding for resistance to harmful leaf beetles.
