Abstract

A field test was conducted using Lindgren traps baited with (1) ethanol, (2) ethanol plus conophthorin, and (3) ethanol, conophthorin, and green LEDs (525 nm) to compare their efficacy for capture of bark and ambrosia beetles. Captures of Cnestus mutilatus were similar with all 3 treatments. Captures of Xylosandrus crassiusculus and other Scolytinae were significantly higher with ethanol-baited traps supplemented with conophthorin and green LEDs, as compared to traps baited with ethanol alone. Results of this study indicate that detection and monitoring of pest Scolytinae may be improved by incorporating conophthorin and green LEDs into the standard ethanol-baited Lindgren trap.

 

Se utilizaron trampas para determinar el atractivo de los 3 diferentes tratamientos sobre la corteza y escarabajos ambrosías (Coleoptera: Curculionidae: Scolytinae): trampas cebadas sólo con etanol, trampas con etanol y conophthorin, y trampas con etanol, conophthorin y LED verde. Las trampas cebadas con etanol integradas con conophthorin y LED verde (525 nm) fueron más atractivas para X. crassiusculus y otros Scolytinae que las trampas cebadas con solo etanol. La captura de Cnestus mutilatus no fue afectada por la adición de conophthorin, o de conophthorin y LED verde en trampas cebadas con etanol. Este estudio indica que trampas cebadas con etanol y suplementadas con el conophthorin y LED verde pueden ser útiles para mejorar el atractivo de X. crassiusculus y otros Scolytinae hacia las trampas cebadas con etanol.
