Attraction of Hylobius radicis and Pachylobius picivorus (Coleoptera: Curculionidae) to ethanol and turpentine in pitfall traps
Environmental Entomology 18 (3), 351-355
Abstract: Pitfall traps were used in field tests to evaluate the relative attractiveness of red pine, Pinus resinosa Aiton, volatiles, turpentine, ethanol, and combinations thereof to adult Hylobius radicis Buchanan and Pachylobius 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 overwintered H. radicis were attracted to the baits. The sex ratio for weevils captured in all traps was 9.1 : 1 females/males for H. radicis and 1.7 : 1 for P. picivorus. A significant relationship was observed between numbers of H. radicis captured in pitfall traps placed in plots of Scotch pine, Pinus sylvestris L., and percentage incidence of foliar symptoms.
