摘　　要：研究通过田间试验评价了15%烟碱、烟草提取物和假莲翘提取物对黄曲条跳甲种群的田间控制作用。结果表明,15%烟碱,烟草提取物和假莲翘提取物对黄曲条跳甲种群均有明显的忌避作用、控制效应或保苗效果。其中,15%烟碱对黄曲条跳甲的田间控制效果较好,其忌避率和保苗效果分别为62.14%,10.22%～23.81%;烟草提取物次之,其忌避率和保苗效果分别为50.72%,9.25%～16.42%,假连翘提取物的控制效果最差,其忌避率和保苗效果分别为45.60%,8.73%～18.13%。结果表明,15%烟碱,烟草提取物和假连翘提取物中含有对黄曲条跳甲种群明显起忌避作用的活性物质。因此,可尝试在蔬菜感虫敏感初期利用烟碱防控黄曲条跳甲,以降低其大田危害。同时,减少化学农药的使用,提高蔬菜的安全性,保护环境。Control effects of 15% nicotinamide, Nicotiana tabacum L. and Duranta repens L. against the striped flea beetle （ SFB）, Phyllotreta striolata （ F. ） were investigated in the fields. The results of this trial showed that 15% nicotinamide had a better control effect than N. tabacum L. and D. repens L. in the fields. The deterrent rates and protecting seeding rates of 15% nicotinamide were 62. 14% and between 10.22% and 23.81% , respectively. However, the deterrent or protecting seeding rates of Nicotiana tabacum L. and Duranta repens L. were between 45.60% and 50. 72% or between 8.73% and 18.13% , respectively. In a word, the results of the trials suggest that it may be a very useful material to protect vegetable or other plants by the use of Nicotinamide in fields.
