摘要

摘要: 植物提取物对苏云金芽孢杆菌Bacillus thuringiensis(Bt)的杀虫活性有不同程度的影响。试验结果表明,处理48 h后,花椒Zanthoxylum bungeanum、假连翘Duranta repens、南洋楹Albizia falcataria、羊蹄甲Bauhinia variegata、番石榴Psidium guajava、荷花玉兰Magnolia grandiflora 的乙醇提取物对Bt的杀虫活性有显著增效作用; 小蜡Ligustrum sinense、胜红蓟Ageratum conyzoides、一品红Euphorbia pulcherrima、烟草Nicotiana tabacum、南洋杉Araucaria cunninghamii、繁缕Stellaria media、光叶子花Bougainvillea glabra、小飞蓬Conyza canadensis、地肤Kochia scoparia的乙醇提取物对Bt杀虫活性有显著拮抗作用;其他植物提取物则没有显著影响。

Abstract: Adjusted mortality rates were used to measure the influences of secondary plant metabolites on Bacillus thuringiensis. Forty-eight hours after treatment, a significant difference (P＜0.01, One-Way ANOVA) was found among the mixtures of ethanol extracts and Bacillus thuringiensis (Bt). While the ethanol extracts of Zanthoxylum bungeanum, Duranta repens, Albizia falcataria, Bauhinia variegata, Psidium guajava and Magnolia grandiflora had synergistic effects on Bt, ethanol extracts of Ligustrum sinense, Ageratum conyzoides, Euphorbia pulcherrima, Nicotiana tabacum, Araucaria cunninghamii, Stellaria media, Bougainvillea glabra, Conyza canadensis and Kochia scoparia had antagonistic effect on Bt. There were no effects on Bt caused by the others.
