东方钝绥螨是叶螨的重要捕食性天敌,对多种叶螨的防控起着重要的作用。东方钝绥螨一直被认为是叶螨的专食性捕食者,其规模化生产不成功极大地限制了其应用。本试验在(25±1)℃、RH 80%±5%、光周期16L:8D的条件下,以甜果螨为食,东方钝绥螨能够完成发育和繁殖,并以此组建了东方钝绥螨试验种群生命表。试验结果表明,东方钝绥螨以甜果螨为食各发育阶段历期较短,分别为卵期1.77 d,幼螨期0.77 d,前若螨和后若螨期各为1.05 d。25℃时东方钝绥螨的世代平均周期为14.07 d,内禀增长率0.18,周限增长率1.20,种群倍增时间3.87 d。日均产卵量1.71粒/d,总产卵量平均22.50粒/雌。由此得出甜果螨是饲养东方钝绥螨的一种很好的替代猎物。
東方鈍綏螨是葉螨的重要捕食性天敵,對多種葉螨的防控起著重要的作用。東方鈍綏螨一直被認為是葉螨的專食性捕食者,其規模化生產不成功極大地限製瞭其應用。本試驗在(25±1)℃、RH 80%±5%、光週期16L:8D的條件下,以甜果螨為食,東方鈍綏螨能夠完成髮育和繁殖,併以此組建瞭東方鈍綏螨試驗種群生命錶。試驗結果錶明,東方鈍綏螨以甜果螨為食各髮育階段歷期較短,分彆為卵期1.77 d,幼螨期0.77 d,前若螨和後若螨期各為1.05 d。25℃時東方鈍綏螨的世代平均週期為14.07 d,內稟增長率0.18,週限增長率1.20,種群倍增時間3.87 d。日均產卵量1.71粒/d,總產卵量平均22.50粒/雌。由此得齣甜果螨是飼養東方鈍綏螨的一種很好的替代獵物。

As an important specific predator, Amblyseius orientalis (Ehara) shows effective control for mites, while lack of large-scale production of A. orientalis restricts its wide application. In this paper, life table of an experimental population of A. orientalis feeding on Carpoglyphus lactis (Linnaeus) was established for investigation of its development and reproduction under controlled temperature (25 ℃) and humidity (80%) conditions. Results showed that developmental duration of different stages of A. orientalis were 1.77, 0.77, 1.05 and 1.05 d, respectively. The mean generation time (T), intrinsic increase rate (rm), finite increase rate (λ) and the time for double population were 14.07, 0.18, 1.20 and 3.87 d, respectively. Daily fecundity and fecundity of single female were 1.71 and 22.50. These results suggest that C. lactis is a good alternative prey for A. orientalis.
