楸蠹野螟与楸树侧枝的关系及其取食部位多样性研究
|
摘要
该文研究楸蠹野螟Omphisa plagialis Wileman的危害与楸树Catalpa bungei侧枝数量及萌芽的相互关系,结果表明侧枝数量越多,受到楸蠹野螟危害形成的虫瘿越多,楸蠹野螟数量相对越多,相关系数0.548,有显著的正相关性,而形成虫瘿又促使虫瘿部位产生新芽,形成更多的侧枝。楸树林龄低,楸蠹野螟取食部位多样性强,随着林龄增长,取食部位呈现出单一性,受害部位逐渐从主干、侧枝、嫩梢到只取食侧枝甚至无取食危害。楸树的林龄与楸蠹野螟的种群数量呈负相关,随着林龄的增长,种群数量呈显著下降趋势。
The paper dealt with the relationship between the damage of Omphisa plagialis and the number of side-branches and their germination on Catalpa bungei. The results showed that the more the side-branches,the more the galls form on the branch after being fed by Omphisa plagialis,and the more the number of the insect,which had a positive correlation with the number of side-branch,their correlative coefficient was 0. 548. The young buds on galls promote to germinate more side branches. The feeding sites appear unicity with the increase of the stand age,while the feeding sites showdiverse in lowaged forest. The damaged sites were different in hosts of different ages. Gradually,the insect fed from stems,side-branches,tender shoots to newsidebranch,even no feeding. The population of O. plagialis had a significant difference with the stands of different ages which declines obviously with the increase of the stand ages.
