Life table of Paederus fuscipes (Coleoptera: Staphylinidae)

Paederus fuscipes Curtis successfully developed to adulthood between the temperatures of 15 to 35 ˚C, with developmental time of every pre-adult stage significantly decreased with increasing temperatures. However, the temperature of 28 ˚C was the optimal temperature for population growth of P. fuscipes: The total development time of pre-adult stage of Desa Wawasan (DW) strain was 17.43 ± 0.16 d, significantly different from Sri Pinang (SP) strain (18.60 ± 0.19 d) and Ampang Jajar (AJ) strain (18.68 ± 0.22 d). Adults from DW also exhibited shorter life span, although the difference among strains was not significant. Additionally, DW strain exhibited two apparent peaks in age-stage specific fecundity. The adults compensated for their shorter life span by increasing their reproductive activity (number of eggs of 121.28 ± 15.98) as close as SP’s (127.30 ± 18.01) and AJ’s (147.45 ± 17.12) to sustain the progeny in the population.  The intrinsic rates of increase (r) of P. fuscipes from DW, SP, and AJ were 0.0773 ± 0.0046 d^–1, 0.0788 ± 0.0051 d^–1, and 0.0873 ± 0.0054 d^–1, respectively; and the net reproduction rates (R₀) were 40.09 ± 7.39 offspring,  45.29 ± 8.74 offspring,  and 42.34 ± 8.25 offspring, respectively. The mean generation time of P. fuscipes from AJ was 43.08 ± 1.07 d, which was significantly higher than that from DW (47.95 ± 1.36 d) and SP (48.57 ± 1.43 d).
