Description

technical field [0001] The invention provides a spotted bean beetle repellent, which has a remarkable repelling effect on spotted bean beetle adults, and also discloses a preparation method of the spotted bean beetle, which belongs to the technical field of pesticide production. Background technique [0002] Spotted Bean Beetle ( Colposcelis signata Motschulsky) belongs to Coleoptera (Coleoptera), Chrysomelidae (Chrysomelidae), and is one of the main pests of spring soybean seedlings in Northeast China. It is widely distributed in the three northeastern provinces of my country, Central China, North China and other regions; it is also distributed in North Korea, Japan, Russia, Southeast Asia and other places. The spotted bean beetle uses adults to damage soybean leaves, stems, cotyledons and shoots. The damaged leaves are notched and hole-like, and the plant damage rate is as high as 70%. Due to the damage at the seedling stage, it is easy to cause the leaves to break as th...
