    Diffusion Behavior of Adults of Tribolium castaneum Released at Different Temperatures

    • The diffusion behavior of adults of Tribolium castaneum released at different temperature conditions was investigated. The results showed that there was no obvious diffusion direction, and most of the adults preferred to stay at the release point at 25 to 30 ℃. The number of T. castaneum adults distributed in different regions had no significant difference when released at 40 ℃. The number of T. castaneum adults distributed in different regions was significantly different when released at 45 ℃. The T. castaneum adults quickly lost their sense of direction at the release point, and soon became heat shock when released at 50 ℃. The adults of T. castaneum rotated in situ at the release point and quickly died when released at 55 ℃. The maximum diffusion rate of adults was 127.43 cm/min at 40 to 50 ℃. The present results provided a reliable basis for effective control of T. castaneum by heat treatment.
