the remainder of the year. A strip (2 cmlong) of
Hercon VaporTape II (10% 2,2-dichlorovinyl dimethyl
phosphate) periodically was placed in the collection
container of the trap to kill captured beetles. The area
beneath traps was mowed and treated with glyphosate
(Roundup PRO [240 ml/11.4 liter]), oryzalin (Surßan
A.S. [70 ml/11.4 liter]), and isoxaben (Gallery 75 DF
[15 ml/11.4 liter]) as needed to prevent weed growth
fromobscuring traps. Traps were suspended froma
tree branch, near the edge of a mixed pine-hardwood
forest on the northern and southern end of the research
station. Traps were placed with the base 60
cmfromthe ground and were emptied at 2Ð5 d intervals
depending on the season and beetle collection
rate. In addition, a Lindgren funnel trap was placed in
two commercial nurseries in northern Grundy County
near Tarlton, TN, and in northern Warren County
near Dibrell, TN. Traps at Dibrell and Tarlton were
checked at 14- to 28-d intervals, depending on the
season and beetle collection rate. Beetle collections
also were occasionally received fromtraps operated in
Franklin and Davidson Counties during 1998 and 1999.
Beetle samples were separated to species for each
sample date and location.
