光肩星天牛在糖槭上产卵部位的选择及刻槽产卵习性研究

摘要

[目的]探讨光肩星天牛在糖槭上产卵部位的选择及刻槽产卵习性.[方法]通过野外及室内饲养观察,研究了光肩星天牛在糖槭树上产卵部位的选择,并分析了其刻槽产卵习性.[结果]光肩星天牛在糖槭上的产卵处距地面高度与树枝胸径、观察孔(刻槽产卵点)数与树枝胸径、产卵处树皮厚度与树枝胸径呈线性相关.光肩星天牛在糖槭上的刻槽产卵习性主要分为产卵部位选择、咬槽、产卵、封槽4个阶段,从开始咬槽至封槽结束历时(38.29±16.47)min.[结论]为综合防治危害绿化树种糖械的光肩星天牛和深入研究光肩星天牛的生殖行为及调节机制提供了参考.%[Objective] The paper was to explore the oviposition site selection of Anoplophora glabripennis in Acer saccharum and its gnawing nidus oviposition habits. [ Method] Through field and indoor rearing observation, the oviposition site selection of A. Glabripennis in A. Saccharum was studied, and the gnawing nidus oviposition habits were analyzed. [Result] The height of oviposition site of A. Glabripennis in A. Saccharum , the number of gnawing nidus oviposition points and bark thickness in oviposition site showed linear correlation with diameter of branch at breast height. The gnawing nidus oviposition habit of A. Glabripennis in A. Saccharum was mainly divided into 4 stages: oviposition site selection, gnawing nidus, oviposition and groove sealing, the duration from gnawing nidus to groove sealing was(38. 29 ± 16.47)min. [ Conclusion] The study provide reference for comprehensive prevention of A. Glabripennis in greening tree species A. Saccharum, as well as further study on reproductive behavior and regulation mechanism of A. Glabripennis.
