采用滤纸浸液法测试了松节油、羟基香茅醛、薄荷醇及其衍生合成的多个系列的萜类化合物对赤拟谷盗Tribolium castanenum的驱避活性。结果显示,质量浓度10 000 mg/L时,所有化合物对赤拟谷盗有不同程度的驱避效果,其中有14个化合物24 h驱避率达100%。质量浓度为1 000 mg/L时,9、27、32号化合物,即内型1-异莰烷基-3-戊醇乙酸酯、羟基香茅醛丙酸酯和蒎酮酸甲酯驱避效果最好,24 h驱避率均在75%上。系列等比浓度测试结果显示,这3个化合物在质量浓度为500~8 000 mg/L时,均表现出很好的驱避活性和良好的持效性,是很有前景的赤拟谷盗驱避剂。
The repellent activities of turpentine, hydroxycitronellal, menthol, and a series of terpenoids derived from them on the Tribolium castanenum were tested by filter paper immersion method. The results showed that when the concentration was 10 000 mg / L, all the compounds had repellent effects on the Tribolium citrinum to a certain degree, of which 14 compounds had a repellent rate of 100% at 24 h. At mass concentrations of 1 000 mg / L, the compounds 9, 27, 32, ie, endo-1-isocatanyl-3-pentanol acetate, hydroxycitronellal propionate and methylpinalone Avoid the best results, 24 h repellent rates were 75%. The results of the series of iso-concentration tests showed that the three compounds showed good repellent activity and good retention at the concentration of 500-8000 mg / L, and the three compounds were very promising Repellent.
