An interference index of population control (IIPC) was constructed for investigating the complex effects of plant protectants, including the effects of repelling insect pests away from the plant, deterring the egg laying of adults and the continuation of feeding, and causing death by toxicity. At the same time, indicated by IIPC, the alcohol extracts of some common plants, such as Eucalytus rubusta, Wedelia chinensis etc. and the neem oil gave very good results to protect the plant against Plutella xylostella. The D-C-Tron NR Petroleum Spray Oil (CALTEX) also gave an excellent effect to protect citrus against red mite. All the experiments show the important role of the repellent effect on the pests.
构建了种群控制干扰指数（IIPC）以研究植物保护剂的综合作用，包括将害虫驱离植物、阻止成虫产卵和持续取食以及通过毒性导致死亡的作用。同时，由IIPC表明，一些常见植物如粗皮桉、蟛蜞菊等的酒精提取物以及印楝油在保护植物免受小菜蛾侵害方面效果非常好。D-C-Tron NR石油喷雾剂（加德士）在保护柑橘免受红蜘蛛侵害方面也有出色效果。所有实验都表明驱避作用对害虫的重要作用。
