Abstract

Conophthorus lambertianae broods within cones in sunny places on the ground can be killed by high temperatures. This conclusion is supported by experimental evidence from four sources: (1) mortality of broods in cones placed in the sun; (2) mortality of cone beetles exposed to high temperatures in the laboratory; (3) measurements of internal cone temperatures occurring in nature; and (4) consideration of some factors that influence internal cone temperatures.
