The life history traits of blow fly Cochliomyia macellaria (Fabricius, 1775) was studied under semi-controlled laboratory conditions at 29.14°C temperature, 72.53% relative humidity, and 12-h photoperiod. The raw data were analyzed based on the age-stage, two-sex life table, considering the development rates among individuals of both sexes. Cochliomyia macellaria survival rate was 0.43 (♂) and 0.40 (♀), while life expectancy was 17.9 (♂) and 20.9 (♀) days, for adult males and females, respectively. The total fecundity was 681.15 eggs/female, with an average of 3.65 batches/female and 199 eggs/batch. The intrinsic rate of increase (r) was 0.327 days, the finite rate of population increase (λ) was 3.35 days, the mean generation time (T) was 17.15 days, and the net reproduction rate (R ) was 272.46 offspring/individual. The population parameters found here corroborates that C. macellaria population act as a r selected species under laboratory conditions. Additionally, development data and accumulated degree days (ADD) for each stage of C. macellaria are provided and its implications for the forensic use are discussed.
在温度为29.14°C、相对湿度为72.53%、光周期为12小时的半控制实验室条件下,研究了丝光绿蝇(Cochliomyia macellaria,Fabricius,1775)的生活史特征。基于年龄-阶段两性生命表对原始数据进行了分析,同时考虑了两性个体间的发育速率。成年雄性和雌性丝光绿蝇的存活率分别为0.43(♂)和0.40(♀),预期寿命分别为17.9(♂)和20.9(♀)天。总繁殖力为681.15枚卵/雌蝇,平均每雌蝇产卵3.65批次,每批次199枚卵。内禀增长率(r)为0.327天⁻¹,种群有限增长率(λ)为3.35天⁻¹,平均世代时间(T)为17.15天,净繁殖率(R₀)为272.46后代/个体。此处发现的种群参数证实,在实验室条件下,丝光绿蝇种群表现为r选择型物种。此外,还提供了丝光绿蝇各阶段的发育数据和积温(ADD),并讨论了其在法医学应用中的意义。
