Description

Technical Field

[0001] The invention belongs to the technical field of pesticide insecticides, and specifically relates to an insecticide and acaricide composition containing tetronic acid compounds and an application thereof. Background Art

[0002] Spirocyclic tetracycline compounds are lipid biosynthesis inhibitors. With their unique chemical structure, novel mode of action, outstanding control effect and low resistance to drug resistance, they stand out from many insecticides and acaricides and become a hot spot for the research and development of insecticides and acaricides in the world. The International Insecticide Resistance Action Committee (IRAC) classifies them as Class 23: acetyl-CoA carboxylase inhibitors, which help synthesize important fatty acids during the growth of pests (mites). Therefore, tetracycline compounds inhibit the activity of ACCase in the process of fat synthesis in pests, destroy lipid synthesis, block the normal energy metabolism of pests, and eventually lead to their death.

[0003] Long-term use of pesticides will inevitably lead to resistance, and spirocyclic tetracycline compounds are no exception. There have been reports of resistance problems at home and abroad. Therefore, in order to extend the service life of such compounds, using them in combination with insecticides and acaricides with negative cross-resistance can effectively reduce the risk of resistance and delay the development of resistance.
