Experimental population ecology of Carcelia matsukarehae Shima (Diptera:Tachinidae)

Abstract

Abstract: This paper dealt with the developmental zero, effective accumulated temperature, adult longevity, adult fecundity and specific life table parameters of tachinid fly Carcelia matsukarehae at temperature 15℃, 18℃, 22℃, 25℃, 29℃, and 32℃, relative humidity 70%～85%, and photoperiod L:D=12:12. The results showed that the developmental zero and effective accumulated temperature for generation were 5.23℃ and 525.73 day-degree, respectively.The adult longevity was 1.35～8.06 days without supplying nutrient but water, and while fed with 30% honey water, their longevity could prolong to 9.63～36.42 days.The optimum temperature for oviposition was 23.6 ℃, maximum eggs laid by a female were 86.The optimum temperature for population growth was 22～25℃. The specific life table parameters of experimental population under temperature 22℃ and 25℃ were calculated. At 22℃, R₀,T₀,r_c and λ were 24.89, 37.33, 0.086 and 1.089, respectively, and at 25℃, they were 20.01, 32.38, 0.09 and 1.10, respectively. The maximum L_xM_x occurred from the 33rd day to the 38th day after adult emergence at temperature 22℃, and from the 29th day to the 34th day at 25℃.
