摘　　要：为了探究澳洲坚果青皮不同溶剂提取物的杀虫活性,以水、乙醇及石油醚为提取溶剂,对澳洲坚果青皮的活性物进行提取,并将提取物对3龄和4龄的思茅松毛虫进行杀虫活性的研究。结果表明:澳洲坚果青皮的水提物、醇提物及石油醚提取物对3龄和4龄思茅松毛虫都有一定的杀虫活性,且浓度越高,杀虫活性越强;相同浓度、相同时间处理下,澳洲坚果青皮的石油醚提取物对思茅松毛虫杀虫活性大于水提液和醇提液;相同的处理下,3龄松毛虫的死亡率高于4龄的死亡率;在一定浓度下对松毛虫进行处理,松毛虫的死亡率随处理时间的延长而增加。澳洲坚果青皮不同溶剂提取物对松毛虫具有不同的杀虫活性,杀虫活性的大小和溶剂的极性大小相反。In order to explore insecticidal activities of different solvents extracts of macadamia peel,the author used water,ethanol and ether as solvents to extract active constituent of macadamia peel,and studied insecticidal activities of different extracts to 3rd instar and 4th instar Dendrolimus kikuchii Matsumura.The results showed that there was certain insecticidal activity of macadamia peel’s water extract,ethanol extract and ether extract to 3rd instar and 4th instar Dendrolimus kikuchii Matsumura,and the higher concentration had the stronger insecticidal activity.Insecticidal activity of macadamia peel’s ether extract to Dendrolimus kikuchii Matsumura was higher than water extract and ethanol extract on same.Mortality and corrected mortality of 3rd instar Dendrolimus kikuchii Matsumura were higher than 4th instar Dendrolimus kikuchii Matsumura in same time and same concentration stress.The Mortality and corrected mortality of Dendrolimus kikuchii Matsumura were increased with the prolonging on some concentration water extract,ethanol extract and ether extract of macadamia peel.There were different insecticidal activities of different extracts of macadamia peel,the insecticidal activities was inversely proportional to polar of extract.
