摘要
【目的】研究不同种群云斑天牛Batocera horsfieldi对寄主植物的适应性。【方法】通过室内取食和产卵试验,测定余姚种群云斑天牛和临安种群云斑天牛对4种寄主植物(黄连木Pistacia chinensis、女贞Ligustrum lucidum、白蜡Fraxinus chinensis和大叶杨Populus lasiocarpa)的取食和产卵行为差异。【结果】取食试验结果显示:余姚种群云斑天牛与临安种群云斑天牛对4种寄主植物表现出不同的取食偏好性。余姚种群取食偏好性从高到低依次为黄连木、女贞、白蜡和大叶杨,余姚种群最喜欢取食黄连木。在选择性条件和无选择性条件下,取食量分别为(1520.00±34.79)和(1815.50±42.13)mm^(2)。临安种群取食偏好性从高到低依次为女贞、黄连木、白蜡和大叶杨。临安种群最喜欢取食女贞,在选择性条件和无选择性条件下,取食量分别为(1347.33±51.95)和(1173.00±75.54)mm^(2)。产卵结果试验显示:余姚种群和临安种群云斑天牛对4种寄主植物表现出比较一致的产卵偏好性,都喜欢在大叶杨上产卵。余姚种群产卵偏好性从高到低依次为大叶杨、女贞、黄连木和白蜡,在选择性和非选择性条件下,在大叶杨上的刻槽数分别为(72.00±5.87)和(82.00±7.64)个,产卵数分别为(60.00±6.19)和(58.00±5.66)粒。临安种群产卵偏好性从高到低依次为大叶杨、女贞、白蜡和黄连木,在选择性和非选择性条件下,在大叶杨上的刻槽数分别为(35.00±5.22)和(30.00±3.85)个,产卵数分别为(22.00±4.51)和(25.00±3.08)粒。【结论】余姚和临安种群云斑天牛为适应不同地理环境,取食偏好寄主不同。余姚种群云斑天牛偏好取食黄连木,而临安种群云斑天牛偏好取食女贞。2个种群云斑天牛产卵偏好寄主相同,均为大叶杨。图3参23。
[Objective]This study aims to explore the adaptability of different populations of Batocera horsfieldi to host plants.[Method]Through indoor feeding and oviposition experiments,the difference of feeding and oviposition behaviors between B.horsfieldi in Yuyao and that in Lin’an to four host plants were measured.[Result]The feeding experiment showed that Yuyao population and Lin’an population had different feeding preference for four host plants.The feeding preference of Yuyao population in descending order was Pistacia chinensis,Ligustrum lucidum,Fraxinus chinensis and Populus lasiocarpa.Yuyao population liked P.chinensis best.Under selective and non-selective conditions,the food intake was(1520.00±34.79)and(1815.50±42.13)mm^(2).The feeding preference order of Lin’an population was L.lucidum,P.chinensis,F.chinensis and P.lasiocarpa from high to low.Lin’an population liked L.lucidum best.Under selective and nonselective conditions,the food intake was(1347.33±51.95)and(1173.00±75.54)mm^(2).Yuyao population and Lin’an population showed consistent oviposition preference for four host plants,and they all liked to oviposit on P.lasiocarpa.The oviposition preference order of Yuyao population was P.lasiocarpa,L.lucidum,P.chinensis and F.chinensis from high to low.Under selective and non-selective conditions,the number of grooves on P.lasiocarpa was 72.00±5.87 and 82.00±7.64,and the number of eggs was 60.00±6.19 and 58.00±5.66,respectively.The oviposition preference order of Lin’an population was P.lasiocarpa,L.lucidum,F.chinensis and P.chinensis from high to low.Under selective and non-selective conditions,the number of grooves on P.lasiocarpa was 35.00±5.22 and 30.00±3.85,and the number of eggs was 22.00±4.51 and 25.00±3.08,respectively.[Conclusion]In order to adapt to different habitat environments,different populations of B.horsfieldi have different feeding preference hosts.Yuyao population prefers to feed on P.chinensis,while Lin’an population prefers to feed on L.lucidum.P.lasiocarpa is the oviposition preference host of both populations.[Ch,3 fig.23 ref.]
