在实验室条件下，研究了温度和寄主种类对腐烂蝇重要寄生蜂--新梢小蜂发育的影响。在15℃、18℃、21℃、24℃、27℃、30℃、33℃和36℃等8个恒温条件下，测定了丽蝇科(Diptera)丽蝇科(Calliphora Albirontalis Malloch)、丽丽蝇Calliphora dubia MacQuart(Calliphora Dubia MacQuart)、丝光绿蝇Lucilia sericata Meigen、大头金蝇ClySomya rufiphala MacQuart和大头金蝇ClySomya Megacephala Fabricius等5种丽蝇的发育时间。用线性模型和非线性模型估算了不同寄主对绿僵菌发育的温度需求(发育起点温度、温度常数和最适温度)。发育上、下限分别为36.6~38.4℃和9.6~11.1℃。发育的最适温度为30.6~31.8℃，在不同温度处理下，不同寄主种类上的发育时间有明显的差异，特别是在所研究的上、下限温度范围内。因此，建议在依赖寄生蜂证据的法医调查中，根据昆虫对死亡时间的估计应尽可能使用特定宿主的发育数据。
The effects of temperature and host species on the development of Nasonia vitripennis Walker (Hymenoptera: Pteromalidae), a forensically important parasitoid of carrion flies, were studied under laboratory conditions. Development time of N. vitripennis on five species of Calliphoridae (Diptera), Calliphora albifrontalis Malloch, Calliphora dubia Macquart, Lucilia sericata Meigen, Chrysomya rufifacies Macquart, and Chrysomya megacephala Fabricius, were determined under eight constant temperatures (15, 18, 21, 24, 27, 30, 33, and 36 °C). Thermal requirements for development (developmental thresholds, thermal constant, and optimum temperature) of N. vitripennis in each host species were estimated using linear and nonlinear models. Upper and lower developmental thresholds ranged between 36.6–38.4 and 9.6–11.1 °C, respectively. The optimum temperature for development was estimated at between 30.6 and 31.8 °C. Statistical differences in the development time of N. vitripennis on the various calliphorid host species were evident within all temperature treatments, particularly at the upper and lower temperature range investigated. As such, it is recommended that insect‐based estimates of time since death in forensic investigations relying on parasitoid evidence should use host‐specific development data where available.
