Abstract

According to the research and observations, the pest damage of peanut varieties planted in the experimental field of the institute was different. Peanut oil is used in all areas of the national economy for the preparation of food, canning, varnish, soap, linoleum, perfumery, printing ink, medicine, and vegetable oil or animal fat. Oilseeds are not limited to obtaining oil, their pulp is a nutritious feed for livestock and a raw material for the processing industry. Compared to other crops (wheat, corn), oilseeds contain protein (45-50%) and oil (25-30%), and their total amount is on average 70-80%. In the article, 24 species of pests specialized in soybeans and peanuts were observed. Among the encountered pests, 8 types of pests with high economic damage were identified. These include Setona sylindricollis Fahr, Callosebruchus maculates Z, Acyrthosiphon onobrychis Fonse, Adelphocoris lineolatus Goes, Liriomysa cicerina Rond, Odontothrips intermedins Uzel, Cicadella virdis L, and Heliothis armigera Hb. Moreover, 6 types of pests, namely, Dociostaurus maroccanus Thunb, Setona cylindricollis Fahr, Sitona lineellus Bansd, Adelphocoris lineolatus Goes, Heliothis armigera Hb, and Agrotis segetum Schiff, were observed in soybean and peanut crops.
