Abstract
Larval head capsule widths, and number of instars of the southern pine beetles found during the summer and winter in Mississippi are compared with those of beetles from Texas, Georgia, and Virginia. Four instars occur in all populations. Head capsules of winter larvae in Mississippi are significantly larger (P<0.05) than those of summer larvae. In addition, summer larvae from Mississippi are significantly smaller (P<0.05) than those of beetles from Texas, Georgia, and Virginia.This publication has 1 reference indexed in Scilit:
