Natural-history traits suspected behind interspecific variations of bark- and wood-boring beetles in response to trap size and design.

ABSTRACT: The performances of traps used for pest monitoring are not well understood. Variable trap sizes and shapes make cross-comparisons difficult. We tested with four Scolytinae species (Coleoptera, Curculionidae) a set of traps of the same model (fan-traps) in four sizes (310, 536, 832.5, 1,200 cm²), and a larger trap with another design (a four-vane trap, 4,500 cm²). A significantly linear relationship was observed between trap sizes and catches for Pityogenes chalcographus, but the catches of Ips typographus, Trypodendron lineatum and T. signatum tapered off. In the literature, comparable tapering-off effects were observed with Xyleborus glabratus (Scolytinae) and Agrilus planipennis (Coleoptera, Buprestidae), but a significant linear response with increasing trap size w
