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.

评估两个人为饲养巴克斯新食肉动物（Acari：Phytoseiidae）的猎物

巴氏新孢子虫

休斯（Hughes）是具有经济潜力的普通掠食性螨，可在受保护的耕作中控制蓟马和两个斑点蜘蛛螨。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埃弗氏菌（Ephestia kuehniella Zeller）和Mycetoglyphus fungivorus Oudemans上的发育和繁殖。在真菌分枝杆菌上，G6的成年前期显着长于G1和G3，而kuehniella大肠杆菌的相应时期在G3和G6上相等，同时比G1长。kuehniella大肠杆菌的产卵率和产卵率高于M. fungivorus。在G1中提供kuehniella卵时，内在的增加率和有限的增加率最高，而在G6中对真菌支原体的获得率最低。女的N.巴克并没有失去自己的能力来捕获并消耗的若虫二斑叶螨后六代饲养上测试猎物科赫。的饲养N.巴克对M. fungivorus和E. kuehniella六代提示其批量生产捕食者的潜在或释放后在作物维持其人口。
