Buprofezin is recognized as a broad-spectrum insecticide and a chitin synthesis inhibitor that specifically targets developmental stages of coleopteran pests. It impacts cellular metabolism by shifting energy production from the aerobic tricarboxylic acid (TCA) cycle and oxidative phosphorylation to anaerobic glycolysis. Moreover, buprofezin increases the production of reactive oxygen species (ROS) by inhibiting cytochrome c oxidase activity[1].[2].
Buprofezin/扑虱灵 动物研究
Animal study
In vivo, when administered orally in single doses of 46.3, 139, and 417 mg/kg, buprofezin is found to accumulate significantly in the liver (35.84%), brain (23.58%), stomach (21.94%), and kidney (18.64%)[1]. Additionally, these doses lead to elevated levels of malondialdehyde (MDA), particularly in the liver and brain, indicating increased oxidative stress[1].
