| 摘 要： | 油茶蛀茎虫属鳞翅目织叶蛾科钻蛀性害虫,该虫主要以幼虫危害油茶枝干的韧皮部和木质部,使树势下降,甚至枯萎死亡。为给该虫的防治和相关研究提供本底资料,对15个样地油茶蛀茎虫的危害程度及寄生情况进行了调查分析。结果表明:在不同生境下,油茶林油茶蛀茎虫的危害程度间的差异显著;江西省新余市渝水区水北镇样地的危害率最高,为36.0%;江西省宜春市巫家镇样地的危害率最低,只有9.0%。油茶蛀茎虫的寄生蜂主要有长体茧蜂、线长体茧蜂、油茶织蛾距茧蜂和大螟钝唇姬蜂。不同样地的寄生率间差异显著;江西省吉安市峡江县戈坪乡样地的寄生率最高,为31.0%;江西省丰城市董家镇样地的寄生率最低,只有8.5%。

| Abstract: | Casmara patronaMeyrick (Lepidoptera: Oecophoridae) is one of the boring insects, whose larva mainly damages phloem and xylem in branches and trunks ofCamellia oleifera. It would result in tree vigor declining and even death. In order to provide some information for prevention and control of the pest, damage levels and parasitic status ofC. patronaat 15 plots were investigated and analyzed. The results showed that damage levels ofC. patronain different habitats had significant differences. Damage rate was the highest (36.0%) in the sample plot of Shuibei Town of Xinyu City, and damage rate was the lowest (9.0%) in the sample plot of Wujia Town of Yichun City. The parasitic wasps of C. patronamainly includedMacrocentrussp.,M. linearisNees,Calcaribracon camaraphilus sp. nov. Quicke and You, andEriborus terbransGravenhost. Parasitic rates at different sample plots had significant differences. Parasitic rate was the highest (31.0%) in the sample plot of Geping Town of Xiajiang County, and parasitic rate was the lowest (8.5%) in the sample plot of Dongjia Town of Fengcheng City. |
