中文摘要：

目的筛选评估萜类化合物对德国小蠊的驱避活性。方法滤纸浸液法生物测定。结果 43个萜类化合物在剂量为340μg/cm2时对德国小蠊雄性成虫驱避活性的初步测试结果显示,羟基香茅醛、薄荷醇、羟基香茅醛丙酸酯、龙脑烯醛缩-1,3-丙二醇等4个化合物表现出了较高的驱避活性。对这4个化合物采用几何浓度梯度进一步测试,并与目前广泛应用的昆虫驱避剂避蚊胺（DEET）进行比较。羟基香茅醛、薄荷醇、羟基香茅醛丙酸酯、龙脑烯醛缩-1,3-丙二醇的驱避中量（RD50）分别为154.7、56.2、165.9和151.3μg/cm2,均低于DEET的RD50（194.5μg/cm2）。结论本项研究结果说明,羟基香茅醛、薄荷醇、羟基香茅醛丙酸酯、龙脑烯醛缩-1,3-丙二醇具有作为蟑螂驱避剂的应用前景。

英文摘要：

Objective To screen and evaluate the repellent activity of terpenoids compounds isolated or synthesized from turpentine against adult male German cockroaches（Blattella germanica）. Methods Bioassay with dipped filter pa- pers. Results Among those 43 terpenoids compounds, four compounds, namely hydroxycitronellal, menthol, hydroxy- citronellal propionate and campholenie aldehyde propylene glycol 1,3 - acetal displayed the most powerful activity in the preliminary screening test using dipped filter paper at the dose of 340 μg/cm2. Further test with geometric series doses for the RD50s （dose of 50% repellency） reveal that the RD50s were 154.7, 56.2, 165.9 and 151.3 μg/cm2 for hydroxycitronellal, menthol, hydroxycitronellal propionate and campholenic aldehyde propylene glycol 1,3 - acetal re- spectively, less than diethyltoluamide （DEET） with the RD50 of 194.5 μg/cm2. Conclusion It is supposed that these four terpenoids, hydroxycitronellal, menthol, hydroxycitronellal propionate and eampholenic aldehyde propylene glycol 1,3 - acetal would be potential and promising cockroach repellents.
