Larval Diapause Variation in a Tree-Hole Mosquito.

The article focuses on the variation in larval diapause in Tree-Hole Mosquito. Photoperiod-sensitive insect species occurring over wide latitudinal ranges usually display clinal variation in diapause response. populations of the Eastern tree-hole mosquito, Aedes triseriatus, occur over an extensive latitudinal range, from southern Florida. Since the maximum summer day length and rate of photoperiod change also increase with latitude, a positive relationship is typically found the latitude of population origin and the length of the photoperiod sufficient to induce diapause.
