摘要： 【目的】大袋蛾Clania variegata是一种严重危害多种植物的食叶性害虫。为了通过合理配植园林植物防治大袋蛾，本研究评估了在悬铃木、月桂、合欢及桃树4种寄主植物上大袋蛾的繁殖潜能。【方法】2018年7月15日至2019年6月21日，在室外纱网隔离环境中测定了大袋蛾分别在悬铃木、月桂、合欢和桃树上的卵期、幼虫期、蛹期、存活率、成虫寿命、雌成虫产卵期和每日单雌产卵量。采用年龄-龄期两性生命表程序TWOSEX-MSChart对大袋蛾发育历期、存活率、成虫寿命及雌虫繁殖力数据进行了分析。【结果】寄主植物种类可显著影响大袋蛾的发育历期和成虫寿命。取食月桂时，大袋蛾2, 3, 4和5龄幼虫的历期显著长于取食其他植物时的；取食桃树时，大袋蛾雌成虫寿命(11.47 d)显著长于取食月桂时的(10.26 d)。大袋蛾取食月桂时的产卵期(7.04 d)显著短于取食悬铃木(7.52 d)、合欢(7.59 d)及桃树(8.11 d)时的。大袋蛾取食悬铃木时的净繁殖力（R₀）(2 015.70粒卵)显著高于取食月桂(1 419.12粒卵)、桃树(1 289.66 粒卵)和合欢(976.67粒卵)时的。大袋蛾取食悬铃木时的内禀增长率(r)(0.02523/d)显著高于取食月桂(0.02377/d)、合欢(0.02304/d)及桃树(0.02194/d)时的。【结论】大袋蛾取食悬铃木时的繁殖潜能显著高于取食月桂、合欢及桃树时的，在园林设计中合理间隔种植月桂、合欢及桃树可能有利于减少大袋蛾对非嗜食植物的危害。

Abstract: 【Aim】 Clania variegata (Lepidoptera: Psychidae) is a major defoliating pest on several tree species worldwide. In order to control this pest through wise arrangement of plant species in gardens and parks, we evaluated the reproductive potential of C. variegata on four host plants (Platanus acerifolia, Osmanthus fragrans, Albizia julibrissin and Amygdalus persica). 【Methods】 The duration of egg, larval and pupal stages, survival rate, adult longevity, oviposition period of female adult and daily number of eggs laid per female of C. variegata on P. acerifolia, O. fragrans, A. julibrissin, and A. persica were recorded in a natural open environment, in Shaanxi Province, northwestern China, from July 15, 2018 to June 21, 2019. The data of developmental duration, survival rate, adult longevity, and female fecundity were analyzed by the age-stage, two-sex life table theory, using TWOSEX-MSChart software. 【Results】 The developmental duration and adult longevity of C. variegata were significantly affected by the host plant species. The duration of the 2nd, 3rd, 4th and 5th larval instars of C. variegata on O. fragrans was significantly longer than that on the other host plants. C. variegata adult females exhibited significantly greater longevity on A. persica (11.47 d) than on O. fragrans (10.26 d). The oviposition period of C. variegata on O. fragrans (7.04 d) was significantly shorter than those on P. acerifolia (7.52 d), A. julibrissin (7.59 d), and A. persica (8.11 d). The net reproductive rate (R₀) of C. variegata on P. acerifolia (2 015.70 eggs) was significantly higher than those on O. fragrans (1 419.12 eggs), A. persica (1 289.66 eggs), and A. julibrissin (976.67 eggs). The intrinsic rate of increase (r) of C. variegata on P. acerifolia (0.02523/d) was significantly greater than those on O. fragrans (0.02377/d), A. julibrissin (0.02304/d), and A. persica (0.02194/d). 【Conclusion】 The reproductive potential of C. variegata on P. acerifolia was significantly greater than those on O. fragrans, A. julibrissin, and A. persica. Alternate planting of O. fragrans, A. julibrissin, and A. persica might help reduce the damage of C. variegata to non-preferable plants.
