在实验室中，在五个不同的恒温条件（15、20、25、30、35 摄氏度）下研究了丽蝇 Protophormia terraenovae（Robineau-Desvoidy，1830）的未成熟发育时间。从产卵到成虫羽化的最短发育持续时间与温度成反比，范围从35℃时的9.19+/-0.3天到15℃时的37.78+/-2.96天。根据五个研究恒温条件下发育速率的线性回归，总未成熟发育的最低发育阈值 (t(L)) 为 8.95 摄氏度（类似于 9 摄氏度），P. terraenovae 的总体热常数 (K) 比阈值高 240.2 +/- 9.3 天度 (DD)。从产卵到化蛹的发育速率的线性回归得出最低发育阈值为 9.8 摄氏度。然而，世界各地从产卵到成虫羽化的发育时间可能不同，而且像 P. terraenovae 这样的全北极物种的热常数在各地也不尽相同。此外，正如本文所示，研究表征同一物种的不同地理种群之间这些参数的变化对于未来的法医昆虫学案例工作具有重要价值。 (C) 2002 Elsevier Science Ireland Ltd. 保留所有权利。
Immature development times of the blow fly Protophormia terraenovae (Robineau-Desvoidy, 1830) were studied in the laboratory at five different constant temperatures (15, 20, 25, 30, 35 degreesC). The minimal duration of development from oviposition to adult emergence was inversely related to temperature, ranging from 9.19 +/- 0.3 days at 35 degreesC to 37.78 +/- 2.96 days at 15 degreesC. From linear regression of development rates at the five studied constant temperature regimes, it followed that the minimum development threshold (t(L)) for total immature development is 8.95 degreesC (similar to9 degreesC) and the overall thermal constant (K) for P. terraenovae is 240.2 +/- 9.3 day-degrees (DD) above the threshold. Linear regression of developmental rates from oviposition to pupariation resulted in a minimum development threshold of 9.8 degreesC. However, it is possible that developmental time from oviposition to adult eclosion might be different in various regions of the world, and that the thermal constant of a holarctic species like P. terraenovae is not same everywhere. Additionally, as the present paper shows, studies characterizing variation in these parameters between geographically distinct populations of the same species would be of great value for future forensic entomological casework.
