The study was conducted on a group of adults of Pentodon bispinifrons Reitter, as it was treated by Nogos at three concentrations (5, 10, 15) ppm and Beauveria bassiana fungus under the influence of three different temperatures: 10, 20 and 30 °C. The results showed that the insect killing rates remained low at the three temperatures when using the Nogos pesticide, while the results when using the fungus extract B. bassiana showed that the killing rate was low at 10 °C but increased at 20 °C as it reached 40% after 8 days after the treatment, while it reached 80% at a temperature of 30 °C after 6 days of treatment.
