在广西南宁市调查台湾乳白蚁Coptotermes formosanus Shiraki对园林绿化树木的危害情况及其筑巢规律。结果表明,在调查的57种树木中,有44种树木受到台湾乳白蚁的侵害,占调查树种的77.19%,树木受害株率13.38%,严重受害株率1.63%。侧柏Thuja arientalis、荫香Cinnamomum burmannii和银桦Grevillea robusta的严重受害率最高,分别为15.85%、13.43%和11.11%。台湾乳白蚁筑巢对树木种类有明显的选择性,可在树心筑巢的树种有16种,隶属于11科14属,其中筑巢率较高的树种为荫香、侧柏、银桦和桂花树Osmanthus fragrans,分别占所调查树木的16.42%、15.85%、11.11%和10.91%;其次为樟树Cinnamonaom camphora、大叶桉Eucalyptus robusta和白千层Melaleuca leucadendta,筑巢率分别为7.98%、5.76%和3.42%。
In Nanning City, Guangxi Province, the investigation of the damage to the tree species of Coptotermes formosanus Shiraki and the rules of its nesting were carried out. The results showed that among the 57 species of trees surveyed, 44 species of trees were attacked by T. terrina, accounting for 77.19% of the surveyed trees, 13.38% of the trees affected and 1.63% of the severely damaged trees. Thuja arientalis, Cinnamomum burmannii and Grevillea robusta had the highest rates of serious damage, accounting for 15.85%, 13.43% and 11.11% respectively. There are 16 kinds of tree nesting in the tree core, belonging to 11 genera and 14 genera. Nest tree species with higher nesting rate are shade incense, arborvitae, silver birch And Osmanthus fragrans accounted for 16.42%, 15.85%, 11.11% and 10.91% of the investigated trees respectively, followed by Cinnamonom camphora, Eucalyptus robusta and Melaleuca leucadendta. The rates of nesting were 7.98% 5.76% and 3.42% respectively.
