Abstract

Light trapping is a common method for monitoring and capturing insects such as the invasive agricultural pest, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae). Efforts to develop more effective trapping methods for H. halys have led to research investigating the response of this insect to potentially exploitable stimuli. A behavioral study was conducted to examine the response of H. halys to various light stimuli. Seven intensities (0 [control: dark], 0.1, 10, 50, 75, 100, and 155 lx) of white light were tested. The most attractive intensity for H. halys was 75 lx for adult males and females. Nymphal instars 2 to 5, adult males, and adult females were also exposed to 75 lx white light. Adult males were significantly more attracted to the light than any other life stage. Adults were also exposed to green, orange, red, white, and yellow light. All colors tested were attractive to H. halys. White light was significantly more attractive than the other tested colors. The findings of this study suggest that the incorporation of a white light into H. halys traps may increase the number captured.

 

Resumen

La trampa de luz es un método común para monitorear y capturar insectos como la plaga agrícola invasora, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae). Los esfuerzos para desarrollar métodos de captura más eficaces para H. halys han llevado a investigar la respuesta de este insecto a estímulos potencialmente explotables. Se realizó un estudio de conducto para examinar la respuesta de H. halys a diversos estímulos de luz. Se ensayaron siete intensidades (0 [oscuro], 0,1, 10, 50, 75, 100 y 155 lx) de luz blanca. La intensidad más atractiva fue de 75 lx para machos y hembras adultas. Los estadios de ninfas de 2 a 5 instares, los machos adultos y las hembras adultas también fueron expuestos a 75 lx de luz blanca. Los machos adultos estaban significativamente más atraídos por la luz que cualquier otro estadio de vida. Los adultos también fueron expuestos a luz verde, anaranjada, roja, blanca y amarilla. Todos los colores probados fueron atractivos para H. halys. La luz blanca fue significativamente más atractiva que los otros colores probados. Los hallazgos de este estudio sugieren que la incorporación de una luz blanca en las trampas de H. halys puede aumentar las capturas.
