Abstract

It is the purpose of this research to study the effect of temperature on the life cycle of D. nebulosa. D. nebulosa is considered a stenothermal species from a warm environment and has been reported in Texas and Florida, the West Indies, Mexico, Central America, and as far south as Brazil. According to the hypothesis of Hunter (1964), the capacity of this species for adaptation to different temperatures would not be expected to be as great as that of a eurythermal species. Stenothermal species are relatively limited by the environmental temperature, and therefore, one would expect a marked decrease in the length of the life cycle with increasing temperatures. On the other hand, eurythermal species are relatively independent of the environmental temperature, soa relatively less decrease in the length of the life cycle with increasing temperature would be expected.
