Functional Analysis of Two Carboxylesterase Genes AsCarE13 and AsCarE15 Associated with Lambda-Cyhalothrin Resistance in Aphis spiraecola

Carboxylesterases (CarEs) are critical enzymes involved in insecticide resistance, yet their specific roles in pyrethroid resistance of Aphis spiraecola remain unclear. In this study, enzymatic activity and synergism bioassays initially implicated CarE involvement in lambda-cyhalothrin resistance of A. spiraecola. RT...

Design, Synthesis, and Fungicidal Activity of Novel α-Methylene-γ-Butyrolactone Derivatives Bearing Benzofuran-2-yl Moiety.

A series of 30 novel α-methylene-γ-butyrolactone (MBL) derivatives were designed and synthesized. Bioassays revealed that several compounds exhibited potent fungicidal activities against Valsa mali, Rhizoctonia solani, and Phytophthora capsici. A25 showed the highest activity against V. mali (EC50 = 0.70 mg/L). Against...
