Pitfall traps were used in field tests to evaluate the relative attractiveness of red pine,Pinus resinosaAiton, volatiles, turpentine, ethanol, and combinations thereof to adultHylobius radicisBuchanan andPachylobius picivorus(Germar). Traps baited with a combination of ethanol and turpentine caught significantly more of both species of weevils than any other bait tested. Only overwinteredH. radiciswere attracted to the baits. The sex ratio for weevils captured in all traps was 9.1:1 females/males forH. radicisand 1.7:1 forP. picivorus. A significant relationship was observed between numbers ofH. radiciscaptured in pitfall traps placed in plots of Scotch pine,Pinus sylvestrisL., and percentage incidence of foliar symptoms.
