説明

6-Alkylthio-2-pyridyl alkanesulfonates, and their sulfoxides and sulfones were synthesized, and their lethal activity was tested to five species of insects and mites. Methanesulfonates, with 6-alkyl-thio, -sulfinyl and -sulfonyl substituents having one to six carbon atoms, showed remarkable insecticidal activity to Nephotettix cincticeps, Nilaparvata lugens and Culex pipiens. Insecticidal activity of 6-alkylthio-2-pyridyl methanesulfonates to strains of Nephotettix cincticeps susceptible and resistant to organophosphates and carbamates was related parabolically to the hydrophobicity of the molecule, the optimum alkyl-thio substituents being C3-C4 alkyl groups. In a series of 6-iso-butylthio-2-pyridyl alkanesulfonates and their sulfoxides and sulfones, the methane-, ethane- and chloromethane-sulfonates showed stronger insecticidal activity than higher alkanesulfonates. The 6-n-propyl-sulfinyl-, -sulfonyl-, 6-iso-butyl-sulfinyl- and -sulfonyl-2-pyridyl methanesulfonates and the 6-iso-butylsulfonyl-substituted ethanesulfonate showed strong inhibitory activity against acetylcholinesterase preparations from the susceptible and resistant strains of Nephotettix cincticeps.
