Abstract

The invention discloses the application of chitin synthase CHSA‑2b / 19b of lepidopteran insects in pest control. The invention discovers malformed wing veins of insects by fully injecting dsRNA that interferes with exon 2b and 19b of lepidopteran insects. Wrinkled and thin, wings smaller, indicating that transcripts containing 2b and / or 19b affect insect wing development. Artificial substances that inhibit the expression of chitin synthase transcripts containing 2b and / or 19b in lepidopteran insects or compounds screened from plants can be used as inhibitors, such as injecting dsRNA of CHSA-2b to lepidopteran insects, The purpose of pest control can be achieved. Similarly, substances that promote the degradation of chitin synthase transcripts containing 2b and / or 19b in Lepidoptera insects, or substances that inhibit the normal function of chitin synthase transcripts containing 2b and / or 19b As a pest insecticide, it can achieve the purpose of pest control.

Description

technical field

[0001] The present invention relates to the application of exons 2b and 19b of the chitin synthase gene of Lepidoptera insects in pest control, and specifically relates to the function of CHSA-2b / 19b affecting the development of pupal wings of Lepidoptera insects, so as to develop around the gene The research and development of transgenes or inhibitors can achieve the purpose of pest control by hindering the normal development of insect wings, affecting their flight, courtship and reproduction. Background technique

[0002] The main component of insect skin and wings is chitin, which is the second largest biopolymer after cellulose. It is a linear polysaccharide complex composed of N-acetyl-β-D Glucosamine (β-N-Acetyl-D-glucosamine) is polymerized through β-1,4 glycosidic bonds. In arthropods, chitin is an important component of the epidermal exoskeleton, which plays an important role in the growth and development of arthropods. The content of chitin in ins...
