【摘要】 本研究以朱砂叶螨为猎物,研究了在23℃?13℃、26℃?16℃、29℃?19℃、32℃?22℃和35℃?25℃五个变温和14L:10D、12L:12D和10L:14D三个光周期共15个组合对加州新小绥螨性比分化及繁殖的影响。明确32℃?22℃的变温与光周期14L:10D组合的雌性比最高,为78.38%。其次为32℃?22℃的变温和光周期10L:14D的组合,为77.32%;32℃?22℃的变温和光周期10L:14D组合的每雌平均产卵量最高为91.12,显著高于32℃?22℃的变温和光周期14L:10D的每雌平均产卵量43.55。32℃?22℃的变温和光周期10L:14D组合利于加州新小绥螨种群发展。该研究结果为规模繁育加州新小绥螨,实现种群快速增长提供了重要理论依据。更多还原

【Abstract】 With Tetranychus cinnabarinus as the prey, sex differentiation and reproduction of Neoseiulus californicus were examined under combinations of 5 fluctuating temperatures(23?13, 26?16, 29?19, 32?22, and 35?25℃, temperatures in photophase/scotophase) and 3 photoperiods(14L:10D, 12L:12D, 10L:14D). A significant higher female rate(78.4%) was detected at the condition of 32?22℃ and 14L:10D. The second higher female rate(77.3%) was observed from the combination of 32?22℃ and 10L:14D. However, the highest fecundity(91.1 eggs/female) occurred in the combination of 32?22℃ and 10L:14D, which is significantly higher than that(43.55) in the combination of 32? 22℃ and 14L:10D. In conclusion, the combination of 32?22℃ and 10L:14D is most beneficial to the reproduction of N. californicus. This finding serves to support the mass breeding of N. californicus.更多还原
