AI Technical Summary

Technical Problem

The increasing resistance of pests to chemical pesticides is leading to reduced crop yields and environmental pollution, necessitating the development of inhibitors targeting new pests to address pesticide resistance in agricultural pests.

Method used

We designed a complex of the detergent molecule lauryl maltose neopentyl glycol (LMNG) and the insect adenosine triphosphate binding cassette superfamily transporter ABCH. Through three-dimensional structural analysis and binding site information, we developed an insecticide targeting ABCH.

Benefits of technology

LMNG significantly inhibited the ATP hydrolysis activity of ABCH, resulting in a 60% mortality rate in red flour beetle larvae and a 90% mortality rate in diamondback moth larvae, providing a highly effective insecticidal effect.
