| Abstract | ||
| The effect of ultra-violet rays 312 nm wavelength on different egg ages (1,2and3) days of the fig moth, Ephestia cautella as well as the effects on early and late pupa exposed for 3, 6, 9and 15 minutes were studied. Results showed that percent of egg hatching and adult emergence were reduced gradually with increasing exposure period, this is because of higher sensitivity of the embryonic cells in the eggs when exposed to this type of radiation. This study also showed significant differences in many biological parameters for the pupae aged 2 days when compared with 7 days old ,the younger one was more effected, therefore, resulted in increasing pupal and adult malformation .This investigation concluded that uv-radiation can be apply as safe and effective method to control the storage pests. | ||
