تقييم كفاءة استعمال غاز الأوزون و درجات الحرارة العالية على طوري البيض و العذاري لخنفساء الحبوب الشعرية (الخابرا)‎ مختبريا : Trogoderma granarium everts coleoptera dermestidae

The effect of the treatments were the combination of ozone gaz with high temperatures ( 35، 40 and 45C) and tempreture alone in addition to control treatment treatments were tested on Egges and Pupae stages of hairy grain beetle Trogoderma granarium (Everts).

Results showed that( Z+H) and (H) treatments were more lethally effective (100%mortality) than to control treatment on Egges and Pupae stages of insect .

The results also showed that first treatment(Z+H) was more effective than the second treatment (H) on two stages , 1Tthe total1T 1Tkillings1T 1T100%(LT100)1T 1Tin eggs1T 1Treached at1T 1Tperiods1T 1T15.001T, 1T13.001T 1Thours and1T 1T18 minutes1T, respectively1T with treatment of1T 1Tthe 1Tozone gaz with high temperatures ( 35، 40 and 45C),when tempreture alone showed 1Texposure to1T 1T0.01T, 1T0.01T 1Tand 30 minutes1T.

,the temperature alone treatment with 35,40C was not effective on Egg and Pupae while the temperature 45C alone and combined with Ozone gaz was more effective on two stages of insect .It was also found that Egg stage was more sensetive to all treatments than Pupae stage at 45 Celsius.
