Abstract

On experiment was conducted to investigate the effect of temperature 45Cْ at 50% LT on treated larvae of hairy grain beetle at relative humidity of 45% . Results showed significant effect of temperature on life parameters of insect .The treatment reduced the development rate for the stage of larvae for more than of the half the duration of the control treatment, more than a half of the average pupation percentages. The average duration was reduced of pupa to the third, while the effect was limited in the rate of emergence of adult. The data were 17 days, 46% , 4 days, 60%, 4 days respectively, compaired to the control treatment which was 29 days, 100%, 64% respectively.
The results also indicated that the treatment showed significant effect on first and second generations originated from treated larvae . An obvious reduction was observed in rate of egg laying, and egg hatch which was reduced to a half and incubation to the third comparred to control treatment ,larvae duration was 18 days, the pupation percente was 73%, the average duration for the pupa was 5 days, adult emergence was 10% and the average of adult life span was 1 day, compared to 63 days, 100% , 7 day , 93% and 7 days respectively in the control treatment for the second generation. These results indicate the feasability of using the lethal temperature for the control of this pest and other stored products pest.
