Abstract:
[Objectives]  To provide baseline information on the effects of temperature on the development and reproduction of Semidalis aleyrodiformis in order to facilitate the application of this species as a biological control agent. [Methods]  Developmental duration and survival rate were measured under different temperature regimes and a life table constructed. [Results]  The developmental duration of each larval stage decreased with increasing temperature. The survival rate of adults was highest at 26 ℃, whereas that rate of larvae decreased at both high and low temperatures. The longevity and oviposition period of adults decreased with increasing temperature. The highest fecundity (445.00 eggs) was observed at 23 ℃, and was not significantly different to that observed at 26 ℃. The maximum net reproductive rate (R0), intrinsic rate of increase (rm) and finite rate of increase (λ), were highest at 26 ℃. [Conclusion]  S. aleyrodiformis can breed and develop at temperatures within the range of 23 ℃ to 29 ℃ but the optimal temperature is 26 ℃. This suggests that this species has potential as a biological control agent in Southern China.
