The analysis of results carried out on revealing the efficiency of using in night LED lamps three, namely red, blue and white colors for increasing growth and development of mulberry nurseries in the greenhouse conditions has been presented. It has been shown that using LED strips improves growth and development of nurseries on in height, leaves quantity and width of nurseries. Moreover, the development degree of nurseries differs on the control variant weakly in case of red lighting one at the same time in the blue and white lighting variants it is essential. The maximal growth of nurseries on height in comparison of control variant in case of white lighting was to 25.0 %, and the minimal one corresponds to case of red lighting, 1.9 %. The average growths of nurseries for a season was 3.3, 13.2 and 15.5 % in cases of red, blue and white lightings, correspondingly. The relative growths of nurseries on the height for a season compared beginning of the experiences were 133.3, 140.0, 163.3 and 170.0 % in cases of control and also led, blue and white lighting variants, accordingly. The most quantity of leaves in case of white lighting variant was 44.4 % more than control one and the least quantity corresponds to the red lighting variant, 8.8 %. The average values of this quantity for a season were 5.7, 21.9 and 24.3 % for red, blue and white lighting variants, correspondingly.

In the present paper the analysis of results of experiences carrying out on testing 5 hormonal affecting insecticides in fight against of mulberry pylalides from biologic active substances, namely Match – 1.0 litter/hectares, Nomolt – 0.3 litter/hectares, Binsegard – 0.5 kilogram/hectares, Al’familin – 0.5 litter/hectares and Rimon star 0.15 litter/hectares has been presented. In these experiences the values of the reached biologic efficiency in period of 15-16 days ones using were 81-100%. Therefore the preparations mentioned above for including to the list of allowed pesticides in agriculture of Uzbekistan for practical using them by farmers producing silkworm cocoons have been recommended.

The analysis of morphological and common features of 20 types insects entering to Pyraloidea superfamily and occurring in Uzbekistan region has been carried out. Their belonging to 2 families (Pyralidae and Crambidae) has been revealed which future to 3 and 6 subfamilies have been subdivided, correspondingly. The information on the morphological features for 3 types from revealed insects has been presented and general features of these insects have been outlined. For example, it has been shown that each insect type damages essentially one concrete agricultural plant that is the monophagous of these insects has been defined.

An analysis of the results of experiments to determine the effectiveness of the use of illuminated pheromone catchers in the fight against mulberry moth was presented. The experiments used pheromone handles impregnated with antioxidant pheromone material and placed on a lamp based on 2 light-emitting diodes operating in the ultraviolet radiation range of 365-370 nm. According to the analysis of the results, it was observed that mulberry moths caught on illuminated pheromone traps were 2.15 times more than non-illuminated catches, and the number of moths caught at night was about 1.75 times higher than the number of moths caught daytime.

Рассмотрено использование энтомофагов — Bracon hebetor и Chrysopa carnea — против вредителей хлопчатника: Helicoverpa armigera Hbn., Tetranychus telarius L. и Thrips Fapaci Lind. Проведен сравнительный анализ результатов исследований по биологической эффективности этих энтомофагов без использования пестицидов и с использованием местных удобрений. Опыты проводили в период выращивания хлопка на полях Узбекистана. Продолжительность опытов составляла 7 месяцев — с марта по сентябрь 2016 г. Объектом исследования служил сорт хлопчатника Султон. Предпосевную осеннюю культивацию земли проводили глубиной 40 см. Под опыты были отведены по 4 грядки на 5 участках земли, отдаленных друг от друга на расстояние 600 – 800 м. Показано, что в борьбе с вредителями хлопчатника без применения пестицидов Bracon hebetor дает более высокий эффект (примерно на 10 – 15 %), чем Chrysopa carnea. Самый лучший результат получен в случае совокупного применения обоих энтомофагов при биологической эффективности до 63 %. Если применение местных удобрений без использования энтомофагов позволяет получить дополнительный урожай до 15 %, то использование Bracon hebetor поднимает этот показатель еще до 2,5 – 3 %, Chrysopa carnea — до 2,2 %, а в их совокупности — до 7 %. Наилучший дополнительный урожай (22 %) получен при совокупном использовании Bracon hebetor + Chrysopa carnea и местных удобрений.
