Cowpea weeevli Callosobruchus maculatus Pic., is one of the most important storage pests of beans including mung bean. In this research, the possibility of using different frequency and priods microwave to control the insect was examined. In this experiment the three stageg of the pest exrosed to frequency of 2450MHz, 200W in periods of 15, 30, 60, 120, 240 and 360 seconds. The results showed that frequency and the time needed to avoid hatching eggs, pupae phase control and inducing adult mortalitywas 200W and 360 secods. In all experiments the mortality rate increased with increas time. According to the results 92.2% mortality of pupae and 96.02% were occurred at 200W and 360s. Also, the results showed that eggs are the most sensitive compase to other stages such a way that 96.11% of mortality occurred at 300W, and duration of 240s, and 200 and 360s. There fore it is recommended 200W and 360s to control all stages of the pest. Manuscript profile

Cotton bollworm and corn stem borers are the most significant pests in the Middle East countries. Habrobracon hebetor is one of the most important parasitoid of some agricultural pests. In this study, we investigate the effect of cold storage on the biological parameters of Habrobrac wasp including percentage parasitism, reproduction, male generation in temperature 5 storage on the within 5, 10, 15, 20, 25 days in laboratory condition on the flour moth 30 days Anagasta kuehnilla (Zeller) that the experiments were conducted at 26ºc, 60 ± 5 % humidity  and 16:8 light\dark ratio. Based on these results, the most percentage parasitism (97.67%), reproduction (28.20 wasps) and adults longevity (7.60 days) were obtained in storage on the within 5 days that show significant difference in comparison with other storages. Also the obtained results show that time saving does not effect on the breeding but mass production of H. hebetor is improved and greatly enhances the performance of this biological agent in pest control.

Oryzaephilus surinamensis L. (Col., Silvanidae) is one of the most important stored product pests in Iran. Regarding to environmental risks of pesticides, scientists are exploring substitute compounds with less hazard to man and environment, such as RGRs. The purpose of this project is to evaluate the efficacy of three IGR insecticides, Tebufenozide, Chromafenozide and Lofux® with two methods of oral and contact on O. surinamensis larvae in laboratory condition. Different concentrations of the above insecticides have been used on 4-5 (young) and 19-20 day-old (old) larvae. Bioassay tests showed that in oral method Lufox (LC50 =9.68) and Tebufenozide              (LC50 =24.49) had the most and the least efficacy on young larvae, respectively. Lufox                  (LC50 =22.82) and Tebufenozide (LC50 =80.18) had also the most and the least efficacy on old larvae, respectively. The most and the least efficacy contact method, on young larvae have been induced by Lufox® (LC50 =1) and Tebufenozide (LC50 =33.9), respectively. Lufox (LC50 =29.2) and Tebufenozide (LC50 =143.03) had the most and the least efficacy on old larvae, respectively. Based on the results obtained, the use of oral method was more effective than useing contact method. Lufox® is a mixture of chitin synthesis inhibitor and juvenile hormone mimic. This combination showed the best performans on larvae O. Surinamensis and can be used safely for controling the pest. Manuscript profile
