摘要
目的筛选评估不同植物精油对德国小蠊的驱避活性,为开发新型蟑螂驱避类产品提供参考。方法采用滤纸药膜测试法进行试验,采用气相质谱-色谱法(GC/MS)进行精油成分分析。结果在1000μg/cm^(2)剂量下,13种植物精油中丁香油、柠檬桉油、玫瑰油、香叶油和肉桂油5种植物精油的驱避效果优于DEET。对5种植物精油设置剂量梯度进一步试验,结果表明驱避率随浓度的增加而上升,5种精油的驱避中量(RD_(50))均低于DEET,其中丁香油的驱避中量最低,为37.47μg/cm^(2)。GC/MS分析出丁香油的主要成分为丁香酚(总含量的83.46%),其驱避中量为38.23μg/cm^(2)。结论丁香油主要成分丁香酚对德国小蠊有较好的驱避效果,具有作为蟑螂驱避类产品的应用前景。
Objective To evaluate the repellent activity of 13 different plant essential oils against Blattella germanica,and provide reference for developing new cockroach repellent product.Methods The repellent effect of essential oil on B.germanica was detected by filter paper diffusion method.The principal components of essential oils were analyzed by GC-MS.Results Among these essential oils,clove oil,eucalyptus oil,rose oil,geranium oil and cinnamon oil showed better repellent effect than DEET at the dose of 1000μg/cm^(2).Further test with series doses showed that the repellent rates increased with the doses.The RD_(50)s(dose of 50%repellency)of these 5 essential oils were less than DEET,and the RD_(50)of clove oil was the lowest,37.47μg/cm^(2).The composition of clove oil analyzed by GC/MS,showed that the main component was eugenol(83.46%of the total content),which held the RD_(50)of 38.23μg/cm^(2).Conclusion Clove oil and its main component eugenol displayed good repellent effect against B.germanica,with the potential as cockroach repellent in application.
