Abstract
Chloromethanesulfonamide (CMSA) is a systemic acaricidal compound which has stronger activity than dimethoate and disulfoton against the citrus red mite, Panonychus citri, the two-spotted spider mite, Tetranychus urticae and the carmine mite, Tetranychus cinnabarinus. LC50 values of chloromethanesulfonamide against the larvae, protonymphs, deutonymphs and female adults of T. cinnabarinus were 74.4, 148.6, 183.1 and 286.6ppm respectively. CMSA showed a systemic acaricidal activity against P. citri when painted on the trunk and leaf surface of a mandarin orange tree or when applied to the soil surface near the tree. Its toxicity to mammals and carp was low.
