以敏感和抗性棉铃虫为试虫，比较测定了DEF、PBO、SV1 和S2 对氰戊菊酯的增效作用。
Synergism of DEF PBO SV1 and S2 to fenvalerate were measured against susceptible and resistant strain of Helicoverpa armigera.

生物测定结果表明，PBO对所测定的7种拟除虫菊酯均有不同程度的增效作用，对氰戊菊酯的增效比最高（119 3），对氯菊酯的增效比最低（2 1）。
The bioassay results indicated that PBO synergised 7 pyrethroids significantly, with the highest synergistic ratio (119 3) for fenvalerate and the lowest (2 1) for permethrin.

通过数据还发现氰戊菊酯中的三个苯环的原子轨道间也存在较强的相互作用。
It is also revealed that there are fairly strong interactions among the atomic orbitals of the three phenyl of fenvalerate.
