2 results about "Insecticide resistance" patented technology

This invention belongs to the field of pesticide compound technology, specifically relating to an insecticidal composition. The active ingredients of the insecticidal composition include active ingredient A and active ingredient B, wherein active ingredient A is a compound of formula (Ⅰ), and active ingredient B is an arylisoxazoline insecticide. The mass ratio of active ingredient A to active ingredient B is 1:30 to 40:1. The compound insecticide of this invention has a significant synergistic effect, reduces the amount of insecticide used, lowers production costs and environmental risks, delays the development of insecticide resistance in pests, and can be used for integrated management of resistant pests, specifically for controlling Hemiptera, Lepidoptera, and Coleoptera pests.

This application provides a detection primer, method, and application for the Y4667D / C mutation of the nicotine receptor in the rice stem borer, belonging to the field of agricultural pest resistance detection technology. The detection primer set is designed for the Y4667D / C mutation site, a target receptor for the rice stem borer's high resistance to diamide insecticides. It includes a first primer set for simultaneous detection of Y4667D and Y4667C, a second primer set for genotypic specific detection of Y4667D, and a third primer set for genotypic specific detection of Y4667C; each primer set contains 6-8 primers (outer, inner, and loop primers). The detection method primarily relies on visual interpretation of genotypes through color changes in the reaction solution, eliminating the need for a thermal cycler. It offers advantages such as multiple tests per tube, flexible splitting, and high sensitivity. This invention is suitable for rapid field detection of mutant genotypes and frequencies in the rice stem borer, providing technical support for diamide insecticide resistance monitoring and scientific management.
