Anastrepha suspensa (Loew) larvae were fumigated with the cyclopropyl compounds methyl cyclopropanecarboxylate, cyclopropyl methyl ketone, and cyclopropyl methyl carbinol. Larvae were exposed for 24 h to rates ranging from 1.1 to 21.4 mg/liter. Typically, fumigated larvae grew and formed puparia, but adults did not emerge. At lower rates adults often only partially eclosed; however, <5% fully escaped from their puparia. Mortality of A. suspensa was 100%with exposures to 2.2mg/liter of methyl cyclopropanecarboxylate, 10.7 mg/liter of cyclopropyl methyl ketone and 21.4 mg/liter of cyclopropyl methyl carbinol. Dissection of puparia revealed that insects fumigated with methyl cyclopropanecarboxylate died at various phases of development; 7% of these specimens were headless pupae.
