Abstract
Unikaryon minutum is a microsporidian parasite of the southern pine beetle, Dendroctonus frontalis. It infects muscle tissue, the alimentary tract, Malphighian tubules, and fat body of larvae and adult beetles (J. D. Knell and G. E. Allen, Acta Protozool. 17, 271-278, 1978). The effects
of U. minutum on southern pine beetle population dynamics are not known, although most beetle populations examined have been infected.
