Biology of Dendroctonus punctatus (Coleoptera: Scolytidae)
Annals of the Entomological Society of America, 1995The biology of Dendroctonus punctatus LeConte was studied in white spruce, Picea glauca (Moench) Voss, forests of boreal western North America and in the laboratory. Engelmann spruce, P. engelmannii (Parry) Engelmann, was not found to be infested in nature but was used successfully for rearing in the laboratory.

Limonene released by the Scolytid beetle Dendroctonus pseudotsugae
Zeitschrift für Angewandte Entomologie, 1976AbstractThe monoterpene limonene was released with known pheromones of both sexes of the Douglas‐fir beetle when stimulated by stridulation of the opposite sex. This compound was previously known as a host tree attractant and a synergist of the aggregative pheromone, but not as a substance either received from the host or biosynthesized by the beetle ...

Masking of the Aggregation Pheromone in Dendroctonus pseudotsugae Hopk.
Science, 1969The pheromone mask released by female Dendroctonus pseudotsugae Hopk. after the male stridulates stops aggregation of beetles in flight, but not arrestment of males, in an interaction of chemically and sonically induced behavior. This masking is viewed as a mechanism for survival through the regulation of attack and

Biology of the Southwestern Pine Beetle, Dendroctonus barberi
Annals of the Entomological Society of America, 1961This species is associated with 60% of the insectcaused losses annually in the ponderosa pine type in Arizona and New Mexico. There it has three generations a year. It flies and attacks green trees from early May to October, most intensely in late July and early August; its development from egg through adult requires 50 to 60 days in the summer months.
