Abstract

Predatory phytoseiid mites as biocontrol agents are increasingly used in pest control programs across the globe, and Neoseiulus cucumeris (Oudemans) is one of them, which is a commercially available agent against various pests of greenhouse crops. This generalist predatory mite can feed on different foods and diets, including small arthropods and pollen. Feeding and reproducing on a pollen diet is a considerable characteristic of this predatory mite that facilitates the cost-effective production of large numbers of this predator so-called mass rearing. Therefore, the effects of saffron (Crocus sativus L.) pollen as an alternative food source on development and reproduction of N. cucumeris were determined over 20 successive generations. In addition, the predation ability of the nymphs and adults of N. cucumeris being switched to natural prey, Tetranychus urticae Koch after 10th and 20th generations was evaluated. The shortest and longest developmental time happened in the 1th and 5st generations, respectively. The predator in the 1st and 20th generations had a higher intrinsic rate of increase (r) (0.171 and 0.170 day-1, respectively) than other generations, while the 5th generation had the lowest value of this parameter. The development and fecundity of N. cucumeris was not significantly different when this predator switched to a diet of T. urticae. The results of this study revealed that rearing of N. cucumeris for 20 generations on saffron pollen did not affect the performance of the predator negatively and this alternative food source can be used for the mass rearing of N. cucumeris.

藏红花花粉对黄瓜新小绥螨发育、繁殖和捕食能力的长期影响

作为生物防治剂的捕食性植物eiid螨越来越多地用于全球的害虫防治计划，而Neoseulus cucumeris（Oudemans）就是其中之一，它是一种商业上可买到的防治温室作物各种害虫的药剂。这种多面手捕食性螨可以以不同的食物和饮食为食，包括小型节肢动物和花粉。以花粉为食进行饲养和繁殖是这种捕食性螨的一个重要特征，它有助于以成本效益高的方式生产大量这种捕食者，即所谓的大规模饲养。因此，通过连续20代的研究，确定了藏红花花粉作为一种替代食物来源对N.cucumeris发育和繁殖的影响。此外，还对10代和20代后转为天然猎物二斑叶螨的若虫和成虫的捕食能力进行了评估。发育时间最短和最长分别发生在第1代和第5代。第1代和第20代的捕食者比其他世代具有更高的内在增长率（r）（分别为0.171和0.170天-1），而第5代的该参数值最低。当这种食肉动物转而以二疣草为食时，库库梅里斯猪笼草的发育和繁殖力没有显著差异。本研究结果表明，用藏红花花粉饲养20代N.cucumeris不会对捕食者的表现产生负面影响，这种替代食物来源可用于大规模饲养N.cucumerics。
