title: Sublethal effects of larval methoprene exposure on adult mosquito longevity.
abstract: Larvae of Aedes aegypti were exposed to sublethal concentrations of the insect growth regulator, methoprene, and the glycogen content of pupae and surviving adults was compared and effects on adult longevity determined. The glycogen reserves in both male and female Ae. aegypti pupae were significantly reduced as a result of methoprene exposure. The longevity of adult females was also significantly reduced, but exposure affected neither the longevity nor the glycogen content of adult males. Adult sugar feeding increased the amount of glycogen in both treated and control females. The reduced longevity of adult females from larval methoprene treatment appeared not to be directly related to reduced glycogen, but rather reflected neuroendocrine abnormalities induced by this juvenile hormone analogue.
