摘要

在爪哇 Perum Perhutani 森林管理区的几个地方，地下白蚁普遍攻击卡茹普（Melaleuca cajuputi）幼苗的根部。这种攻击被怀疑与卡茹普特树苗根部的化学成分有关。本研究的目的是确定卡茹布树苗根萃取物作为地下白蚁 Coptotermes curvignathus Holmgren（直翅目：Rhinotermitidae）引诱剂的生物活性。提取过程按照 ASTM D1108-96 标准进行，并使用气相色谱-质谱法（GC-MS）对提取物进行表征。提取物的生物活性测试采用引诱和无选择取食生物测定法进行。结果表明，卡军普特幼苗的平均根提取率为 4.94%。浓度为 0.50%、0.75% 和 1.00% 的提取物溶液的吸引力分别为 45.33%、62.00% 和 74.67%。C. curvignathus 白蚁的死亡率为 9.63% 至 24.44%。Cajuput 苗根提取物的致死浓度 50 为 2.45%（无毒）。气相色谱-质谱分析表明，提取物中含有亚油酸，具有吸引昆虫的潜力。

Bioactivity of Cajuput Seedling n-Hexane Extract as an Attractant for Subterranean Termite Coptotermes curvignathus Holmgren (Isoptera: Rhinotermitidae)

Subterranean termite attacks on cajuput ( Melaleuca cajuputi ) seedling roots were widespread in several of Java’s Perum Perhutani Forest Management Units. This attack was suspected to be related to the chemical components of the cajunput seedling roots. This study was conducted to determine the bioactivity of cajuput seedling root extract as an attractant for the subterranean termite Coptotermes curvignathus Holmgren (Isoptera: Rhinotermitidae). The extraction process was performed according to ASTM D1108-96, and the extract was characterized using gas chromatography-mass spectrometry (GC-MS). Bioactivity testing of the extracts was carried out using attractiveness and no-choice feeding bioassays. The results showed that the average root extraction yield from cajunput seedlings was 4.94%. The attractiveness of the extract solutions at concentrations of 0.50%, 0.75%, and 1.00% were 45.33%, 62.00%, and 74.67%, respectively. The mortality rate of C. curvignathus termites ranged from 9.63% to 24.44%. Cajuput seedling root extract’s lethal concentration 50 was 2.45% (non-toxic). GC-MS analysis showed that the extract contained linoleic acid, which has the potential to attract insects.

期刊介绍： The Journal of the Korean Wood Science and Technology (JKWST) launched in 1973 as an official publication of the Korean Society of Wood Science and Technology has been served as a core of knowledges on wood science and technology. The Journal acts as a medium for the exchange of research in the area of science and technology related to wood, and publishes results on the biology, chemistry, physics and technology of wood and wood-based products. Research results about applied sciences of wood-based materials are also welcome. The Journal is published bimonthly, and printing six issues per year. Supplemental or special issues are published occasionally. The abbreviated and official title of the journal is ''J. Korean Wood Sci. Technol.''. All submitted manuscripts written in Korean or English are peer-reviewed by more than two reviewers. The title, abstract, acknowledgement, references, and captions of figures and tables should be provided in English for all submitted manuscripts.
