دراسة تأثير التفريغ الهوائي بمستويات مختلفة مع درجات حرارة وأزمنة تعريض مختلفة على موت بالغات خنفساء الطحين المتشابهة Tribolium confusum (Coleoptera : Tenbrionidae)‎

Abstract EN

The results of the impact of different pressures that the lower of pressure increased the number of dead adults, on the other hand the results showed that the high temperature increased the mortality rate of adults.

The results showed that the increased exposure time increased the insect death rate, and In the study of the effect of low pressure and temperature interference, the highest mortality rate of adult was 58.89 at 15 ml / bar and 45 minutes.

The effect of the overlap between the pressures and the different exposure times.

The results showed that the highest rate of dead adults was 39.17 at 15 m / bar and 40 mins, In the study of the effect of temperature overlap with exposure times, the highest mortality rate was 36.67 at 45 and 40 minutes.

The results showed that the low pressure, temperature and exposure times increased the mortality rate, Bar, 45 ° C and 40 mins exposure time.

This study showed that low pressure (low vacuum) at 15 ml/bar with 45 ° C in 45 minutes had a fatal effect on the tested insect.

It was also found that alone pressure did not have much effect in the fight against T.

confusum, which required a long period of time to reach high rates of death, but when combined with high temperatures, the mortality rate was high when exposure was shorter Time
