背景
专业捕食性瓢虫 Cryptolaemus montrouzieri 是粉蚧的有效天敌，在这些害虫的生物防治中发挥着关键作用。然而，由于依赖粉虱的平行培养或需要 Ephestia kuehniella 卵作为昂贵的人造猎物，其大规模生产变得复杂。
结果
在这里，我们为捕食者开发了一种基于花粉的人造食物，以降低其对自然猎物的依赖。我们发现这种人工饲料对于这种捕食者的幼虫和成虫来说是一种有效的替代食物。人造食物不仅支持第一代（F0）捕食者的发育和繁殖，而且支持下一代（F1）捕食者的发育和繁殖。尽管C. montrouzieri在人工食物上的发育时间和产卵前期分别比在天然猎物柑橘粉蚧Planococcus citri上长约1.5天和4天，但其未成熟存活率、繁殖力和卵孵化率与粉蚧相似。此外，以天然或人工食物维持的成年蒙鲁齐耶里氏菌也具有类似的饥饿抵抗力。
结论
我们的研究结果表明，以花粉为基础的人工饲料可以作为孟鲁齐氏隐翅虫饲养的替代食物，并表明其有可能支持这种捕食者的大规模生产和在生物控制计划中的更广泛应用。 © 2016 中国化学工业学会。
BACKGROUND
The specialist predatory ladybird Cryptolaemus montrouzieri is an effective natural enemy of mealybugs and plays a key role in the biological control of these pests. However, its mass production is complicated by the dependence on parallel cultures of mealybugs or the need for Ephestia kuehniella eggs as an expensive factitious prey.
RESULTS
Here we developed a pollen-based artificial food for the predator to lower its dependence on natural prey. We found that this artificial diet was an effective alternative food for larvae and adults of this predator. The artificial food supported the development and reproduction of the predator not only in the first generation (F0) but also in the next generation (F1). Although the developmental time and preoviposition period of C. montrouzieri on the artificial food were ca 1.5 days and 4 days longer than on the natural prey, the citrus mealybug Planococcus citri, respectively, its immature survival, fecundity and egg hatch were similar to those on mealybugs. In addition, adult C. montrouzieri maintained on natural or artificial food had a similar starvation resistance.
CONCLUSIONS
Our results suggest that the pollen-based artificial diet can be used as an alternative food in the rearing of C. montrouzieri, and indicate its potential to support the mass production and wider application of this predator in biological control programmes. © 2016 Society of Chemical Industry.
