摘  要：
【目的】粉螨等储粮害螨易于获得和大量饲养,被广泛用作商业化大量繁殖捕食螨的替代猎物,为了明确常见粉螨等仓储害螨对斯氏钝绥螨Amblyseius swirskii (Athias-Henriot)的饲养潜力。【方法】室内分别对3种替代猎物(甜果螨Carpoglyphus lactis (L.)、腐食酪螨Tyrophagus putrescentiae (Schrank)、椭圆食粉螨AleuroglyphusovatusZachvatkin)饲养的斯氏钝绥螨生命表参数进行测定。【结果】斯氏钝绥螨取食3种替代猎物均能从卵发育至成螨并繁殖后代。取食甜果螨、腐食酪螨、椭圆食粉螨的斯氏钝绥螨雌螨的世代历期分别为6.43、9.20、6.30 d,平均每雌总产卵量分别为31.70、8.39和11.50粒,内禀增长率rm分别为0.191 8、0.055 0、0.116 2,周限增长率λ分别为1.211 4、1.056 5、1.123 2。此外,以甜果螨饲养的雌成螨寿命(39.02d)也是最长的。取食3种猎物的内禀增长率rm和周限增长率λ均以取食甜果螨的值为高。【结论】甜果螨是这3种猎物中最适于大量繁殖斯氏钝绥螨的猎物螨。

摘  要：
[Objectives] To evaluate the potential of common flour mites and grain mites, which are easy to obtain and mass rear, as substitute prey for mass rearing Amblyseius swirskii. [Methods] Life table parameters of A. swirskii reared on three substitute prey species, Carpoglyphus lactis, Tyrophagus putrescentiae and Aleuroglyphus ovatus were measured under lab conditions of(25±1)℃, RH 65%±10 % and L︰D=16︰8. [Results] The developmental period of A. swirskii reared on the three kinds of substitute prey was 6.43, 9.20, 6.30 d, respectively, and average female fecundity was 31.70, 8.39 and 11.50 eggs, respectively. The intrinsic rate of increase(rm) was 0.191 8, 0.055 0, 0.116 2, respectively, and the finite rate(λ) of increase was 1.211 4, 1.056 5, 1.123 2, respectively. A. swirskii laid more eggs and had lived longer when fed on C. lactis than on the two other substitute prey species tested. [Conclusion] C. lactis was the best of the three substitute prey species tested for rearing A. swirskii.
