Efficacy of Artemisia herba alba seed extract and aqueous copper sulphate powder in controlling the larval role of the grain beetle Trogoderma granarium everts

Abstract

The study examined the effect of the alcoholic extract of   Plant seeds of Artemisia herba alba and inert powder, Anhydrated copper sulphate   CuSo4 in controlling the lightning roles of the hairy grain beetle Trogoderma granarium(Everts) reared on wheat seeds. The results showed effective effects in killing the insect stages by rearing the larvae on wheat treated with the materials used in the experiment. Four concentrations of the extract were used: (10.5, 1.5 2), while the concentrations of the inert powder were (10, 20, 30, 40 gm. The results showed that the highest percentage of killing in the wormwood extract for the first larval age reached 93.33% at a concentration of 2% in a time of 96 hours, and that the lowest percentage Recorded kill rate of 3.33% A time of 24 hours at a concentration of 0.5% for the third and fifth stages, respectively. While the highest kill rate recorded for the sulphate-bearing powder for the first and second lightning age, respectively, was 100% at all concentrations (10, 20, 30, 40)gm for the first phase at a time of 96 hours, and the lowest kill rate recorded for the second phase was 0% at a concentration of 20 gm. At 24 hours, the lowest kill rate for the fourth stage is 3.33% at 20% concentration in 24 hours.
