摘要
采用索氏提取法,以乙醚作为提取溶剂提取柑桔皮、臭椿树皮、辣椒粉的植物精油,研究了其对米象、锯谷盗、赤拟谷盗、小眼书虱的控制作用。结果表明:臭椿皮精油和辣椒精油对4种储粮害虫均有较强的驱避作用,柑桔皮精油对小眼书虱若虫有极为显著的引诱作用。3种植物精油对米象成虫具有较强的触杀活性,对锯谷盗成虫具有较强的熏蒸活性;对锯谷盗成虫的当代种群抑制率都达到了100％,对米象成虫的当代种群抑制作用也较强。
Essential oils were extracted by Soxhlet extractions with anhydrous diethyl ether from Citrus suavissima Tanaka, Ailanthus altissima L. and Capsicum frutescensp L. , and their bioactivities on Sitophilus oryzae, Oryzaephilus surinamensis, Tribolium castaneum adults and Liposcelis paeta nymphae were detailedly investigated in the paper. The results showed that the essential oils extracted from A. altissima and C. frutescensp significantly repelled the four species of important stored - grain insects, the essential oils extracted from C. suavissima could distinctly attract L. paeta nymphae. All of the essential oils possessed strong contact - killing effects on S. oryzae adults and fumigant activities on O. surinamensis adults. All of the essential oils successfully inhibited O. surinamensis and S. oryzae current population, especially, the current population percentage of O. surinamensis reached 100%.
