| 摘 要： | 通过对沟眶象Eucryptorrhynchus chinensis(Olivier)越冬代成虫和幼虫在地下生活状态的分析可知:成虫在地下的分布以东、西方向较多,在树根正下方向的最少,仅为0.47%;幼虫在地下的分布无方位差异;46.01%的成虫分布在地下21～30 cm深度,42.24%的幼虫分布在地下31～40 cm深度;27.70%的成虫分布在距树干21～30 cm范围,66.01%的幼虫分布在距树干0～10 cm范围;38.67%的幼虫体长为21～25 mm;64.64%的幼虫处在直径11～30 mm的根中。 |

| Abstract: | Most of the overwintering adults of Eucryptorrhynchus chinensis located in the east and west directions underground and the adults under the roots(0.47%) were the fewest,but there was no obvious difference in nymph distribution indirection.The suitable overwintering depth for the adults was at the range of 21-30 cm(46.01%) underground and 21-30 cm(27.70%) away from the trunk while the suitable overwintering depth for nymphs was at the range of 31-40 cm(42.24%) underground and 0-10 cm(66.01%) from the trunk.The body length of 38.67% overwintering nymphs was at the range of 21-25 mm and 64.64% overwinter nymphs located in the root 11-30 mm in diameter. |
