Abstract

We have plotted the complete range of flight temperatures for the southern pine beele, the first such figures for any bark beetle.The optimum flight temperature was about 27^oC.Observed minimum and maximum flight temperatures for southern pine beetle were 6.7^oC and 36.7^oC, respectively. Projected thresholds are 5.6^oC and 38^oC.The observed minimum of 6.7^oC is the lowest ever recorded for any scolytid. This minimum is 7.8^oC lower than previous estimates from field studies and 15.3^oC lower than previous estimates from laboratory studies.Solar insolation may explain these discrepancies.
