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.
