Abstract

Environmental factors, such as photoperiod can play an important role in the development and performance of predatory mites. The influence of five photoperiod regimes (0: 24, 8: 16, 12: 12, 16: 8, and 24: 0 h; Light: Dark) on the population parameters of the predatory mites, Amblyseius swirskii Athias-Henriot and Neoseiulus cucumeris (Oudemans) was studied under the laboratory conditions at 25 °C and 25 ± 1 °C, 65 ± 5% RH. Regarding A. swirskii, the longest and shortest total pre-adult and total preoviposition periods (TPOP) were in the photoperiod of 12 L:12D and 16 L:8D, respectively. The oviposition days, adult longevity, total life span, fecundity, gross reproductive rate (GRR), and net reproductive rate (R₀) of the predator had no significant difference in all photoperiods tested. The intrinsic rate of increase (r) and the finite rate of increase (λ) in 16 L:8D photoperiod had no significant difference with the other photoperiods tested except 12 L:12D. Regarding N. cucumeris, the shortest total pre-adult and TPOP were in full darkness. The oviposition days and fecundity were significantly higher in 16 L:8D than the others. The value of R₀ in 16 L:8D was significantly higher than 8 L:16D. The highest values of the parameters r and λ were observed in full darkness, which had no significant difference with 16 L:8D and 24 L:0D. According to the results, the photoperiod regime had a more significant influence in terms of development and reproduction on N. cucumeris than A. swirskii, and 16:8 (L: D) h photoperiod was recognized as the proper regime for their rearing.

不同光周期制度对 Amblyseius swirskii 和 Neoseiulus cucumeris（蛔虫：Phytoseiidae）生命特征的影响。

光周期等环境因素在捕食螨的发育和表现中起着重要作用。在 25 °C、25 ± 1 °C、65 ± 5%相对湿度的实验室条件下，研究了五种光周期制度（0：24、8：16、12：12、16：8 和 24：0 h；亮：暗）对捕食螨 Amblyseius swirskii Athias-Henriot 和 Neoseiulus cucumeris (Oudemans) 种群参数的影响。就 A. swirskii 而言，最长和最短的成虫前期和产卵前期（TPOP）分别是在 12 L:12D 和 16 L:8D 的光周期内。天敌的产卵天数、成虫寿命、总寿命、繁殖力、总繁殖率（GRR）和净繁殖率（R0）在所有光周期下均无显著差异。除了 12 光周期：12 光周期外，16 光周期：8 光周期的固有增长率（r）和有限增长率（λ）与其他光周期没有显著差异。就 N. cucumeris 而言，在全黑条件下，成虫前期和成虫后期的总时间最短。16 L:8D 的产卵天数和受精率明显高于其他光周期。16 L:8D 的 R0 值明显高于 8 L:16D。在全黑条件下，参数r和λ的值最高，与16 L:8D和24 L:0D没有明显差异。结果表明，光周期制度对 N. cucumeris 的发育和繁殖的影响比对 A. swirskii 的影响更大，16:8（L:D）小时的光周期被认为是饲养 N. cucumeris 的适当制度。

期刊介绍： Experimental and Applied Acarology publishes peer-reviewed original papers describing advances in basic and applied research on mites and ticks. Coverage encompasses all Acari, including those of environmental, agricultural, medical and veterinary importance, and all the ways in which they interact with other organisms (plants, arthropods and other animals). The subject matter draws upon a wide variety of disciplines, including evolutionary biology, ecology, epidemiology, physiology, biochemistry, toxicology, immunology, genetics, molecular biology and pest management sciences.
