The influence of beta-cypermethrin, a commercial insecticide, and Cicuta virosa L var. latisecta Celak (Umbelliferae:Cicutal), an insecticidal plant, on the spontaneous ultraweak photon emissions from larvae of Spodoptera litura Fabricius and Zophobas mono Fabricius were studied. The increased percentages of spontaneous photon emission intensities from S. litura treated with 0.1 and 1 mu g/ml beta-cypermethrin were both lower than those of the control in the 24 post-treatment hours, remarkable difference could also be observed during the same period from 1 mono treated with beta-cypermethrin at 0.156, 0.313 and 0.625 mu g/ml. The increased percentages of spontaneous photon emission intensities from the two mentioned, insects treated with 10,100 and 1000 mu g/ml petroleum ether fraction of C virosa L var. latisecta, which displayed little activity against whole insects, could also be changed noticeably. The present study indicated that change in the intensity of spontaneous ultraweak photon emission from insect could be used as a novel method for screening insecticidal compounds with very low content in plant.
