寄生虫是昆虫（通常是黄蜂或苍蝇），在其他昆虫（它们的宿主）体内或其上产卵。取食寄主的寄生蜂产卵寄生寄主，直接取食寄主获取营养。温度是影响昆虫行为反应的最关键因素。很少有研究集中在不同的生活阶段的温度变化对寄主取食寄生蜂的行为的影响。本文研究了温度对食虫蜂Eretmocerushayati雌蜂生活史特征和生命表参数的影响。我们的研究结果表明，在成虫前期和成虫阶段经历的温度显着改变生活史特征（未成熟的发展，成虫寿命，宿主喂养和繁殖力）。提高成虫前期温度，导致发育时间较短的未成熟阶段的寄生蜂，降低温度在成虫期增加繁殖和寿命。最重要的是，我们发现寄主取食事件随温度而变化，而不是生活阶段。在除胁迫温度（34 °C）外的所有温度下，寄生蜂的日取食能力均随温度的升高而增强。此外，在未成熟阶段和成年阶段转换温度可以增加生命表参数的值，其中最高的内禀增长率（r）出现在30/26 °C处理中。本研究为寄生性天敌的大量饲养提供了新的思路。
Parasitoids are insects (usually wasps or flies) that lay eggs within or on other insects (their hosts). Host-feeding parasitoids lay eggs to parasitize the host and feed directly on the host for nourishment. Temperature is the most critical factor affecting insect behavioral responses. Few studies have focused on the impacts of variable temperatures across different life stages on the behaviors of host-feeding parasitoids. This study investigated the effects of temperature experienced during the preadult and adult stages on the life history traits and life table parameters of females of a host-feeding parasitoid,Eretmocerus hayati. Our results show that the temperatures experienced during the preadult and adult stages significantly change life history traits (immature development, adult longevity, host feeding and fecundity). Increasing the preadult temperature resulted in shorter development times for immature stages of the parasitoid, and decreasing the temperature during the adult stage increased reproduction and longevity. Most importantly, we found that host-feeding events changed with temperature rather than life stage. The daily host-feeding ability of the parasitoid increased with increasing temperature at all temperatures except the stress temperature (34 °C). Furthermore, switching temperatures at the immature stage and adult stage can increase the values of life table parameters, with the highest intrinsic rate of increase (r) occurring in the 30/26 °C treatment. This study provides new insight into the mass rearing of parasitic natural enemies.
