Abstract

Abundance and population dynamics of adult Sphenophorus inaequalis were monitored at 4 bermudagrass golf courses in Florida. Sphenophorus inaequalis was present at 3 of the courses, but was the dominant billbug species at one public golf course in Gainesville, FL. Peak activity occurred from Jun to Aug in both 2006 and 2007 in Gainesville. Sphenophorus inaequalis appears to be univoltine and populations are localized within Florida.
