Evaluation of traps of six different designs to capture pine sawyer beetles (Coleoptera: Cerambycidae)

Abstract

Summary1 Sawyer beetles (Coleoptera: Cerambycidae) and metallic wood‐boring beetles (Coleoptera: Buprestidae) attack recently killed or felled trees. They are attracted to potential hosts by volatiles and possibly by visual cues. We examined traps of six different designs to determine the role of silhouette and shape in the capture of pine sawyer beetles, Monochamus L.2 Traps with a round black cylinder, a single vane (clear or black), or cross vanes (clear or black) all mounted above a pan were compared to an open pan. Each pan contained soapy water to retain insects.3 Traps with a black silhouette were significantly more effective in capturing male and female Monochamus scutellatus (Say) than traps with or without clear vanes. For both sexes of M. mutator LeConte, pan traps were as effective as traps with a black silhouette. Silhouette was not important for the capture of male and female M. notatus (Drury). Trap catches for the six trap types were not significantly different for male Buprestis maculativentris Say.4 A pan trap with a black silhouette is recommended for general use in capturing wood‐boring cerambycids and buprestids.

“…The importance of visual cues in host selection behavior has been reported in many phytophagous insects [2,4,10,19,24], and studies have demonstrated that visual cues are used in the host-finding behavior of Cerambycid species [8,17,18]. Further studies on how visual cues are utilized in combination with attraction to host volatiles should clarify the host selection precess of M. alternatus.…”

Host Volatile Attractants and Traps for Detection ofTetropium fuscum(F.),Tetropium castaneumL., and Other Longhorned Beetles (Coleoptera: Cerambycidae)

“…In each year, a factorial experiment was run with three trap types, either baited with two spruce blend lures (Ϸ300 mg/d) or left unbaited to serve as controls, for a total of six treatments. In 2001, the trap types were (1) 12-unit multiple funnel trap (Lindgren 1983, Phero Tech 1997; (2) Intercept panel trap (IPM Technologies, Portland, OR); and (3) cross-vane pan trap (de Groot and Nott 2001). In 2002, the funnel trap was replaced with IPM-Intercept panel traps that had been coated with Rain-X (Pennzoil-Quaker State, Burlington, Ontario, Canada).…”

“…Positive response to monoterpenes, ethanol, and other conifer volatiles has been shown for some species of cerambycids (Gardiner 1957, Ikeda et al 1980, Phillips et al 1988, Ché nier and Philogè ne 1989b, Allison et al 2001, 2003, de Groot and Nott 2001, Morewood et al 2002a), but little is known of the BSLBÕs response to host volatiles. In 1990, BSLB adults (originally misidentiÞed as the native beetle, T. cinnamopterum Kirby) were captured on turpentinebaited traps intended to capture bark beetles in Point Pleasant Park (Robertson 1990).…”

Attractive responses by Monochamus galloprovincialis (Col., Cerambycidae) to host and bark beetle semiochemicals

“…It has been shown that traps with black silhouettes are significantly more effective in capturing woodborer cerambycids, including M. scutellatus, than traps with clear vanes (de Groot and Nott, 2001). In another experiment, black-panel cross-vane traps were more effective than dry multiplefunnel traps for capturing several North American Monochamus species .…”
