采用类同合成法对吡虫啉分子结构进行改造，合成出了５ 个新取代－ ２ － 硝基亚氨基－咪唑烷化合物，并且对这５ 个化合物用萝卜蚜进行了初步药效试验，发现５ 个化合物都有不同程度的药效，显示出其均可作为先导化合物，从而进一步优化分子结构开发成为一种高效、低毒、较低成本新农药的良好前景。
The imidazoline molecular structure was modified by the same synthesis method to synthesize five novel substituted 2-nitroimino-imidazolidine compounds. The five compounds were tested with radish aphids and found that 5 Compounds have different degrees of efficacy, showing that they can be used as a leading compound, thereby further optimizing the molecular structure of the development of a high efficiency, low toxicity, low cost new pesticide good prospects.
