Abstract

A Frontalure-33 baited livetrap that excluded clerid beetle predators was used to capture adult males of the southern pine beetle (SPB), Dendroctonus frontalis Zimmermann and estimate the natural incidence of the microsporidan, Unikaryon minutum Knell and Allen, and the nematode, Contortylenchus brevicomi (Massey) Ruhm in trap catches. No significant difference in the incidence of U. minutum was found between trapped SPB (@M @M) and SPB (@M @M and @V @V) reared from infested trees, but C. brevicomi incidence was consistently lower in trapped males. Incidence of the microsporidan and nematode did not differ significantly between reared SPB males and females.
