| 中文摘要: |
| 为了对比杨树和核桃树两种寄主植物上云斑天牛成虫产卵方式的差异，本研究于2013年通过林间定期调查的方法得到了云斑天牛成虫在两种寄主植物上的产卵规律。杨树上，产卵刻槽沿树干一周，卵产于韧皮部或者木质部；核桃树上，产卵刻槽沿着树干上下排列，卵产于树皮缝内。两种寄主植物上，产卵刻槽的数量均随着树干高度的增高而减少，但在不同高度范围内没有差异（df=2,6，F=0.866；df=2,15，F=0.071），且在不同方向上也没有差异（F1=0.691；F2=0.646；F3=0.994）。另外还调查了寄主植物胸径与产卵刻槽数量之间的关系，结果表明，产卵刻槽不会随着寄主植物胸径的增大而增多。这些研究结论为进一步完善云斑天牛的生物学特性提供了理论依据。 |
| 英文摘要: |
| To ascertain the differences of oviposition pattern of Batocera lineolata adult on Populus spp. and Juglans regis, spawning patterns of adult on two host trees were obtained by regular investigation in 2013. Eggs were oviposited in phloem or xylem by encircling the trunk on Populus spp., but inner the bark crack along the trunk on J. regis. The number of oviposition site decreased with the increase of tree height of both two host plants, but there were no significant difference in height (df=2,6，F=0.866；df=2,15，F=0.071) and direction (F1=0.691；F2=0.646；F3=0.994). In addition, the relationship between host tree DBH and oviposition site was surveyed, the result showed that the number of oviposition site wouldn’t increase with the host tree DBH. The study will provide theoretical basis for further improve the biological characteristics of B. lineolata. |
