Abstract
Average fat content and pronotal width of newly emerged adults of Dendroctonus frontalis Zimmerman varied with season in east Texas. Fat content of beetles Beetles were smallest during the months of July, August and September. Females, in general, were larger and had higher fat contents than males, regardless of emerging during the spring and fall was greater than season. Implications in relation to bark beetle dispersal that of beetles emerging during the summer and winter. and seasonal behavior are discussed.
