Abstract

The invention discloses a botanical insect trehalase inhibitor and the application thereof. The inhibitor comprises castanospermine which can be obtained by screening botanical compounds and used for manufacturing trehalase-targeted pesticides or active lead compounds. The inhibitor has good effect on inhibiting trehalase in cotton bollworms and other insects.

Description

technical field [0001] The invention relates to an insect enzyme inhibitor, in particular to a plant source insect trehalase inhibitor and application thereof. Background technique [0002] Trehalose is a non-reducing disaccharide formed by combining two glucose molecules through hemiacetal hydroxyl groups. It is widely found in lower plants, algae, bacteria, insects and invertebrates. A variety of biologically active substances have a miraculous protective effect. For insect organisms, trehalose is the blood sugar in the body and is the most important energy source; trehalose is mainly used as a flight energy storage and cryoprotectant. As an important blood sugar in insects, trehalose exists in almost all tissues and organs of insects. The level of trehalose in the hemolymph plays an important role in regulating the intake of carbohydrates and the dynamic balance of nutrients in insects. The lack of trehalose in insects will affect the metabolism of insects, and then af...
