Evaluation the Efficacy of Ozone and High Temperature to Control Egges and Pupae Stages Laboratory for Hairy Grain Beetle (khapra) Trogoderma granarium Everts Coleoptera : Dermestidae

Abstract

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

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
