摘要: 胡瓜新小绥螨Neoseiulus cucumeris(Oudemans)广泛地用于蓟马类害虫的防治、控制及管理。本研究克隆了1条胡瓜新小绥螨钠钾泵α亚基基因序列,分析了温度对雌螨生殖力及钠钾泵α亚基基因表达的影响。在15、20、25和30℃下,胡瓜新小绥螨在25℃时生殖力最优。在上述温度条件下胁迫48 h,雌螨钠钾泵α亚基在15和30℃下表达量显著上升,能量代谢活跃。表达量越多,表明能量消耗越大,投入生殖的能量就越少,结合生殖力研究结果,二者一致。高温或低温均会降低胡瓜新小绥螨的生殖力,且高温影响更为严重。

Abstract: Neoseiulus cucumeris (Oudemans) is widely used as a biological control agent for some insect pests. The effects of temperature on the fertility and the expression of Na+/K+-ATPase α subunit based on the clone of Na+/K+-ATPase α subunit gene of female adults were assessed in the present paper. The results show that 25℃ is the optimal temperature for female fertility among a temperature series of 15, 20, 25 and 30℃. Expression of Na+/K+-ATPase α subunit gene increased significantly in females stressed at 15 and 30℃ for 48 h, indicating that energy metabolism in stressed females was more active than in females at optimal temperature. The results suggest that females would spend less energy for fertility if they were stressed with high or low temperature.

Key words: Neoseiulus cucumeris, temperature, fertility, Na+/K+-ATPase α subunit
