Population density of grape moth in the Lower Don region.
Keyword(s):
The article introduces a study in the field of monitoring the number and density of the population of grape moth using pheromone traps. In the course of this research, we found that the grape moth in 2019 developed in three generations. On the night peak flight, the largest pest population in the first generation was 2–3 insects/day; in the third generation – 1 insect/day. The population density of the grape moth in the conditions of the Novocherkassk branch of the Experimental field did not exceed the economic threshold and during the development of three generations was low. Hence, protective measures were not carried out.
