Comparison of arboreal beetle catches in wet and dry collection cups with lindgren multiple funnel traps

Abstract

We compared the effectiveness of a dry collection cup (with an insecticide killing strip) to a wet collection cup (containing antifreeze) for use with Lindgren multiple-funnel traps in catching several common species of bark and wood-boring beetles, and their associates in southern pine forests. All traps were baited with either the binary combination of ethanol and (±
)-
a-pinene or the quaternary combination of (±)-ipsenol, (±)-ipsdienol, ethanol, and (±
)-±
-pinene. We found that cup treatment had little, if any, effect on catches of Ips avulsus (Eichhoff) and I. grandicollis (Eichhoff) (Coleoptera: Scolytidae), Alaus myops (F.) (Elateridae), Chalcophora Solier species (Buprestidae), Temnochila virescens (F.) (Trogositidae), and Lasconotus Erichson species (Colydiidae). In contrast, catches of the following species were signiÞcantly less (by 40Ð97%) in traps with dry cups than in traps with wet cups: Hylobius pales Herbst and Pachylobius picivorus LeConte (Curculionidae); Buprestis lineata F. (Buprestidae); Acanthocinus obsoletus (Olivier), Arhopalus rusticus nubilus (LeConte), Monochamus titillator (F.) and Xylotrechus sagittatus agittatus (Cerambycidae); Hylastes porculus Erichson and Xyleborinus saxeseni (Ratzeburg) (Scolytidae); and
