Abstract: 

In an attempt to find a practical method of natural products to control the stored-product pests, the combined effect of gamma radiation and essential oil from Cuminum cyminumn L. on the mortality rate of Trogoderma granarium larvae were investigated. Experiments were carried out at 27±1oC and 65±5% R.H. and three experimental regimes were designed: 1) application of gamma radiation and essential oil simultaneously; 2) fumigation of irradiated adults after 3 days; 3) irradiation of fumigated adults after 3 days. The mortality was assessed 24 hours after the first treatment. The results showed a significant synergistic effect of the combination of gamma radiation with the C. cyminum essential oil on T. granarium larvae. The best combination in T. granarium larvae was the third regime, where at doses of 900 and 1000 Gy of gamma in combination with each 3 doses of essential oil after 35 days 100% mortality among T. granarium larvae was wrought, while in application of gamma radiation (1000 Gy) alone 36.66% mortality after 35 days was wrought. The results indicated that the acceptable combined effect of gamma radiation with the C. cyminumn essential oil in management of T. granarium larvae.
