The egg parasitoid Trichogramma turkestanica Meyer is being evaluated as a biological control agent against the Mediterranean flour moth, Ephestia kuehniella Zeller, in flour mills. The longevity, parasitism and host-feeding of the parasitoid at four constant temperatures (15-30 degrees C) has been determined in the laboratory. The highest fecundity occurred at intermediate temperatures. The number of host eggs killed by host-feeding per female was highest at the two lower temperatures. A very conservative estimate of host-feeding showed that it accounts for approximately half of the mortality of host eggs at 20 and 25 degrees C and thus could constitute a major mortality factor for the flour moth population.
卵寄生蜂土耳其赤眼蜂（Trichogramma turkestanica Meyer）正在面粉厂中作为防治地中海粉螟（Ephestia kuehniella Zeller）的生物防治剂进行评估。已在实验室测定了该寄生蜂在四个恒定温度（15 - 30摄氏度）下的寿命、寄生率和取食寄主情况。最高繁殖力出现在中等温度下。每个雌蜂通过取食寄主杀死的寄主卵数量在两个较低温度下最高。对取食寄主的一个非常保守的估计表明，在20和25摄氏度时，它约占寄主卵死亡率的一半，因此可能是粉螟种群的一个主要死亡因素。
