摘要
植物提取物对苏云金芽孢杆菌Bacillusthuringiensis(Bt)的杀虫活性有不同程度的影响。试验结果表明,处理48h后,花椒Zanthoxylumbungeanum、假连翘Durantarepens、南洋楹Albiziafalcataria、羊蹄甲Bauhiniavariegata、番石榴Psidiumguajava、荷花玉兰Magnoliagrandiflora的乙醇提取物对Bt的杀虫活性有显著增效作用;小蜡Ligustrumsinense、胜红蓟Ageratumconyzoides、一品红Euphorbiapulcherrima、烟草Nicotianatabacum、南洋杉Araucariacunninghamii、繁缕Stellariamedia、光叶子花Bougainvilleaglabra、小飞蓬Conyzacanadensis、地肤Kochiascoparia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。
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.
