Abstract
The aspen bark beetle, Trypophloeus populi Hopkins, was studied in nature to determine the number of larvae emerging from galleries. Fifty-five percent of the larvae in aspen galleries in the field developed into adults. An artificial rearing medium for third instar larvae of the beetles was also developed from aspen bark sawdust and nutrient agar. The optimum medium contained a ratio of 1:2 parts of agar to sawdust which gave 70 percent emergence of the beetles and less than 10 percent of adult mortality over the 36 days following emergence.
