. Tests on two laboratory strains of Drosophila pachea (Patterson & Wheeler) showed that adults can tolerate concentrations up to 1% methanol vapour in air. Greater concentrations resulted in markedly decreased longevity. When exposed to low concentrations of methanol (0.25% and 0.5%), adults showed increased longevity, however. The populations showed no variability for the ten enzyme systems that were examined. Females retained mature ovarioles at all concentrations of methanol except 4% and 8%, and showed a preference to oviposit on media containing 0% and 0.5% methanol.
