The insecticidal activity of 2-methyl-5-(2-propynyl)-3-furylmethyl 2,2,3,3-tetramethylcyclopropane-1-carboxylate (Y-4042) was tested against Musca domestica vicina, Culex pipiens pallens and Blattella germanica by various bioassay methods. The topical application tests showed that Y-4042 is about 7 times as toxic as allethrin against mosquitoes. The KT_<50> of Y-4042 by dryfilm assay and the mortality in 24hr after the application against the other insects were superior to those of allethrin. As formulated in mosquito coils and electric evaporizer mats, Y-4042 proved its particular utility as the fumigants because of its high volatility : against mosquitoes, the Y-4042 coil showed KT_<50>=17min and mortality=100% at 0.4% concentration, whereas the allethrin mosquito coil showed 6.6min and 22.5%, respectively. Y-4042 was also so characteristic that very few mosquitoes recovered from paralysis caused by the application, in contrast to the heretofore known pyrethroids which often permit their revival.
