| 中文摘要: |
| 为明确产卵木段粗细对星天牛Anoplophora chinensis刻槽产卵的影响、了解刻槽产卵习性及产卵规律，以不同直径悬铃木Platanus acerifolia木段为产卵材料，通过无选择和选择性产卵试验，测定了星天牛在悬铃木上产卵部位选择，并监测了星天牛的产卵过程。结果表明：星天牛产卵过程主要包括刻槽部位选择、咬槽、产卵和封槽4个阶段。星天牛在不同直径的悬铃木木段上都能刻槽产卵，但木段的粗细对刻槽数量、产卵量的影响差异显著，对空槽率、卵的大小没有影响。刻槽产卵行为主要集中在直径10~15 cm木段。在直径3~5 cm木段上刻槽数量和产卵量最低，显著低于直径大于5 cm的木段。在武汉地区，星天牛产卵高峰期在6月下旬-7月中旬，孵化高峰期在7月中下旬。该结果为深入研究星天牛的生殖行为，精准监测和防控提供参考。 |
| 英文摘要: |
| In order to elucidate the oviposition behavior of Anoplophora chinensis, including impact of different trunk diameter on oviposition, gnawing nidus oviposition habits and oviposition dynamics on its host plant Platanus acerifolia, Selective and non-selective oviposition tests were performed to examine the oviposition site selection on the host plant, as well as the oviposition stages. The results showed that four oviposition stages were observed for A. chinensis: Site selection, scar gnawing, oviposition and scar sealing. A. chinensis could gnaw oviposition scars on all diameters of P. acerifolia trunk sections. Trunk diameter had significant impact on the number of scars and effective oviposition, but did not affect unsuccessful oviposition rate and egg size. The oviposition behavior occurred mainly on trunk section of 10~15 cm in diameter. Lowest number of oviposition scar was found on 3~5 cm diameter trunks, significantly lower than on trunks of over 5 cm in diameter. In Wuhan, the highest number of oviposition occurs from late June to mid July, while hatching occurs in mid to late July. These results can provide insight for future research on reproduction, precise monitoring and control. |
