Abstract EN

This study was carried out in the laboratories of the College of Agriculture - Muthanna University 2017 - 2018 to find out the effect of the Insect growth regulator Applaud in some life stages of the Trogoderma granarium (Everts).

The results of the insect egg treatment were shown in the three concentrations of Applaud (0.5, 1 and 1.5) g / L decrease in the rate of hatching ratio of the treated eggs to reach 00% at the concentration of 1.5 g / L compared to the control treatment which reached 93.3% .

While the larval ages treatment showed that the first, second and third larvae instars of Khapra were more sensitive than the fourth and last instars, The results showed an increase in the duration of larval instars due to the treatment of the first instar of the insect that reached (38 and 41 days) at the concentrations (0.5 and 1.5) g / L of the growth regulator Applaud, The pupation percentage of larvae treated decreased to (33.5 and 00 % ), The duration of the pupal stage increased to reach (11 and 13 days) at the concentrations (0.5 and 1) g / L respectively, The percentage of emergence of adults decreased to (22.38 and 00 % ), The duration of the adult stage was reduced to reach (0.5 and 1) g / L to (12 and 9 days) respectively, It was found that the increased concentration of the growth regulator had a fatal effect on the treated larvae as it was unable to reach subsequent stages.
