Abstract
The insecticidal activity of methyl substituted cyclohexenylmethyl and cyclohexadienyl-methyl chrysanthemate was investigated from the view point that these compounds have partial structure of the hypothetically cyclized rethrolones. 4-Methyl-l-cyclohexenylmethyl-and 4, 5-dimethyl-1, 4-cyclohexadienylmethyl chrysanthemate showed the equivalent insecticidal activity to houseflies as those of natural pyrethrins or α-dl allethrins. The insecticidal activity of other related compounds is also discussed.
