另一方面,化学式(A)的化合物可以以微囊剂型应用。
化学式(A)的化合物可与环糊精混合,以配成一种施用于害虫及其聚集区的含环糊精的复合物。
将在农业上可应用的添加剂,应用到杀虫的组合物中,以增进活性成份的性能,以及减少例如发泡、结块与腐蚀。

生物活性
实施例4
在三龄早期(0-24小时)的烟草蚜虫幼虫、烟芽夜蛾的背部腹部用作试验用的浓度的试验化合物丙酮稀释液1微升进行局部处理。
将出处理过的幼虫放入一个装有人工饲料的、内有用塑料格子格开成多个单独小室的、盖好的陪氏培养皿中。使该容器保持27℃及光照期为16小时直到所有的幼虫要末死亡要末脱皮成5龄幼虫。通常,在对每个昆虫应用约0.004至0.070微克的试验化合物(4至70ppm)之后,就可观察到杀虫的活性。
