Planes of origin and bioecological development characteristics of tomato moth (Tuta Absoluta Meyr)

This article analyzes the literature on the origin and spread of the tomato moth (Tuta absoluta), which has been causing significant damage to the tomato crop in Uzbekistan in recent years, and provides information on scientific research on its development, damage, and countermeasures in Uzbekistan. In this, it is shown that it damages cultural crops and weeds belonging to a number of other ituzum family, and partially develops in them as well. According to the scientific research of foreign scientists, one female tomato moth lays up to 160–260 eggs when the air temperature is 300C. During the year, it was found that the pest gives up to 9–10 generations. According to our information, 300.9 eggs were laid in the air temperature of 25–30°C and 55–60% humidity, and 290.1 eggs were laid when the humidity reached 65–70%. During the year, 9–12 generations have been confirmed. When the level of damage caused by the tomato moth during the development of the plant was studied, it was observed that if the tomato is damaged during the seedling period, the plant dries up before reaching the flowering period, when the tomato is damaged during the flowering period, the tomato yield is reduced by 72.2%, and when it is damaged during the fruiting period, the fruits are reduced by 53.3%.
