短时高温暴露对土耳其斯坦叶螨和截形叶螨的影响
Effects of brief exposure to high temperature on Tetranychus turkestani and T.truncatus (Acari: Tetranychidae)
摘要
Abstract
[Aim]In order to determine the influence of high temperature shock on the survival characteristics and population dynamics of Tetranychus turkestani and T. truncatus. [Methods]The egg hatching rate, survival rate and developmental duration were investigated after the eggs, larvae and adults of the two mites were exposed to high temperature (38℃ , 42℃ and 46℃) for 2 -6 h . [Results]The survival rate of the treated eggs and larvae decreased with the increase of exposure temperature and treatment time. The high temperature shock showed no influence on the survival rate, pre-oviposition period, oviposition period and fecundity of the treated male mites, but significantly decreased the hatching rate of their eggs. The egg hatching rates of T. turkestani and T. truncatus exposed to 46℃ for 6 h decreased by 15. 5% and 18. 0% , respectively. [Conclusion]High temperature exposure has significant effects on the egg hatching rates, survival rates and developmental duration of T. turkestani and T. truncatus, but has no effect on the longevity and reproduction of their female adults, and T. turkestani has stronger adaptability to high temperature than T. truncatus.关键词
