AbstractThe influence of temperature on the dispersal rate and flight initiation of Tribolium castaneum（Herbst) adults was studied at different temperatures and on different substrates. The dispersal rate was monitored both on a solid surface and on wheat in a perspex groove at both uniform temperatures and over a temperature gradient. The results indicate that the minimum temperature that initiated crawling was 17℃ both on the solid surface and wheat bulk. The minimum temperature for flight initiation was 25 ℃ on both substrates. The dispersal rate of adults significantly increased with temperature within the range of 15-25℃ for horizontal movement, and within the range of 15-20℃ for vertical movement in the wheat column. The dispersal rate on the solid surface was 39-59 times higher than that on wheat. The dispersal rate in wheat columns was 12-31 times higher than in vertical columns without wheat. The ideal flight temperature was 25-30 ℃ for both male and female T. castaneum.
