| Abstract | ||
| In the first part of this study the Khapra Beetle eggs were impacted to the corn seeds that treated with concentration 2×106 spore/ml of Bacillus thuringiensis (Berliner) and 2×106 spore/ml of Trichoderma harizanum (Rifia) and 4×105 spore/ml of Beauveria bassiana (Vuill), they were highly effective, the mortality percentages of this insect were 92.5, 88 and 92.6% respectively. In the second part of this study three kinds of sacks were treated with the same concentrations of the forenamed agents, the results showed that these agents can protect the corn seeds foon infestation by this insect for six months compared with that of untreated ones and the P.C.V. sack is the best. | ||
