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 27oC.Observed minimum and maximum flight temperatures for southern pine beetle were 6.7oC and 36.7oC, respectively. Projected thresholds are 5.6oC and 38oC.The observed minimum of 6.7oC is the lowest ever recorded for any scolytid. This minimum is 7.8oC lower than previous estimates from field studies and 15.3oC lower than previous estimates from laboratory studies.Solar insolation may explain these discrepancies.
