Females of the blowflies Calliphora vicina (Robineau-Desvoidy) and Lucilia sericata (Meigen) (Diptera: Calliphoridae) maintained in sheltered outdoor cages and supplied with excess food, oviposited later than would have been expected from the temperature-sum. The survival rates of the caged flies was high and the isolation of flies from predation, extreme temperatures and food shortages is likely to have contributed to this. Despite good survival rates, subsequent egg production over the greater part of the adult life span was reduced to approximately 24% for C. vicina and approximately 55% for L. sericata, of the potential expected from the published temperature-sums required for the maturation of successive egg batches. The data suggest that under field-cage conditions there is a considerable variation in egg development between individuals of the same age and that this variation should not be overlooked, since it may have significant implications in ecological and forensic investigations; however, the cause of this variability remains unclear. While lower than expected, the reproductive outputs recorded in the cages were nevertheless considerably greater than those that have been estimated for blowflies in the field and illustrate the potential for population increase in these species under favourable conditions. The possibility of a greater energy investment in flight activity relative to reproductive output in C. vicina compared to L. sericata is proposed.
将红头丽蝇（Calliphora vicina，Robineau - Desvoidy）和丝光绿蝇（Lucilia sericata，Meigen）（双翅目：丽蝇科）饲养在户外有遮蔽的笼子里，并提供过量食物，它们的产卵时间比根据积温预期的要晚。笼养苍蝇的存活率很高，苍蝇与捕食、极端温度和食物短缺隔离开来可能是造成这种情况的原因。尽管存活率很高，但在成年寿命的大部分时间里，随后的产卵量对于红头丽蝇来说降至约为连续批次卵成熟所需的已公布积温预期潜在产卵量的24%，对于丝光绿蝇来说降至约55%。数据表明，在野外笼养条件下，同一年龄个体之间的卵发育存在相当大的差异，这种差异不应被忽视，因为它可能在生态和法医调查中有重大影响；然而，这种变异性的原因仍不清楚。虽然低于预期，但笼子里记录的繁殖产出仍然大大高于对野外丽蝇估计的产出，并说明了这些物种在有利条件下种群增长的潜力。有人提出，与丝光绿蝇相比。红头丽蝇在飞行活动中相对于繁殖产出可能投入了更多能量。
