ABSTRACT Neoseiulus barkeri (Hughes) is a generalist predatory mite with economic potential to control thrips and two spotted spider mites in protected cultivation. We evaluated the development and reproduction of N. barkeri on Ephestia kuehniella Zeller and Mycetoglyphus fungivorus Oudemans in the first (G1), third (G3), and sixth (G6) generation of rearing. On M. fungivorus, pre-adult duration was significantly longer in G6 than in G1 and G3, while on E. kuehniella the corresponding periods were equal in G3 and G6, meanwhile longer than that in G1. Fecundity and oviposition rate were higher on E. kuehniella than on M. fungivorus. The intrinsic rate of increase and the finite rate of increase were the highest when E. kuehniella eggs were offered in G1, whereas the lowest rates were obtained on M. fungivorus in G6. Female’s N. barkeri did not lose their capacity to capture and consume nymphs of Tetranychus urticae Koch after six generations of rearing on tested prey. Rearing of N. barkeri on M. fungivorus and E. kuehniella for six generations suggested their potential for mass production of the predator or sustaining its population in the crop after release.

两种人工猎物饲养 Neoseiulus barkeri (Acari: Phytoseiidae) 的评价

摘要 Neoseiulus barkeri (Hughes) 是一种多面手捕食性螨，具有在保护栽培中控制蓟马和二斑叶螨的经济潜力。我们在第一代 (G1)、第三代 (G3) 和第六代 (G6) 饲养中评估了巴氏猪笼草在 Ephestia kuehniella Zeller 和食真菌 Mycetoglyphus Oudemans 上的发育和繁殖。M. fungvorus G6的成虫前期显着长于G1和G3，而E. kuehniella G3和G6的相应时间段相等，而G1则长于G1。E. kuehniella 的繁殖力和产卵率高于 M. fungvorus。内在增长率和有限增长率在 G1 期间提供 E. kuehniella 卵时最高，而在 G6 中获得的 M. fungusorus 获得的增长率最低。女N。barkeri 在被测试的猎物上饲养六代后，并没有失去捕获和食用叶螨科赫若虫的能力。将 N. barkeri 饲养在 M. fungvorus 和 E. kuehniella 上六代表明它们有可能大规模生产捕食者或在释放后维持其种群数量。
