Observational analysis reports on how temperature extremes affect southern pine beetle abundance, suggesting ecological implications.
The effect of extremes of temperature on the abundance of the southern pine beetle is here reported. The factors considered were low winter temperature and high summer temperature. Low winter temperatures were often found to be associated with the termination of outbreaks of this insect.High summer temperatures were effective only in felled exposed logs during part of the summer.
