    摘要: A new pyrethroid compound which is low in toxicity to fish and a pesticidal composition containing the same as an active ingredient are provided. The above pyrethroid compound is a substituted cyclopropanecarboxylic acid ester of the general formula: ##STR1## (wherein A is a hydrogen atom or an ethynyl group) Despite its broad pesticidal spectrum and high pesticidal activity, this ester is very low in toxicity to man and domestic animals and especially low in toxicity to fish as compared with the conventional pyrethroid compounds.
