Abstract
In a study Match and Trigard (insect growth regulators) were used against the eggs and larval instars of Khaprah beetle Trogoderma granarium Everts. The results showed a reduction in eggs hatching reach 0.00% at the concentration 0.50 and 0.75 ml/L for match and 0.3g /L for the Trigard compared with 86.30 % at the control treatment . Mortality rates of the larval stage coming from the treated eggs reach 100% at the Conc. 0.50 and 0.75 ml/L for Match and 0.3 g/L for Trigard. The first larval instars was more sensitive than the fourth and the last instar .Mortality rates of the 4th and last instars reach 100 , 96.70 and 93.30 % respectively at the conc. 0.75 ml/L of Match and 100% for the 1st and 4th instars treated with Trigard at the conc. 0.3g/L and 95.00% for the last instar at the same conc. Developmental period of Larval stage of treated larvae increases also. Adult emerges from pupa reduced and the sick larvae took abnormal behaviors by movement and color changes and the shape of body parts at the begging of 3rd Larval stage.
