The effectiveness of a green light emitting diode (LED) trap at capturing the West Indian sweet potato weevil, Euscepes postfasciatus (Fairmaire) (Coleoptera: Curculionidae) in a sweet potato field

Abstract

A light emitting diode (LED) color ray was used to determine the most effective light color to capture the West Indian sweet potato weevil, Euscepes postfasciatus (Fairmaire). Preference tests were conducted using four colors of LED ray (blue, green, yellow and red) at fixed light quanta in the laboratory. The weevils preferred the green LED to the three other LEDs. The effectiveness of a green LED trap was subsequently compared with that of a sweet potato root trap in a sweet potato field with mature potatoes and the green LED trap was confirmed to be applicable for monitoring of the number of weevil.

“…Previous studies have reported that the attractive effect of the green LED to insect pests. For example, Nakamoto and Kuba (2004) reported that the green LED (536 nm) was more attractive than blue LED (470 nm) to West Indian sweet potato weevils (females) in a sweet potato field. In addition, Chen et al (2004) reported that the yellow sticky card (YC) equipped with lime green LED (530 nm) traps captured more leafhoppers and western flower thrips than YC in greenhouse.…”

“…Attraction to green wavelengths has also been noted to occur in other members of the Curculionidae. For instance, Nakamoto & Kuba (2004) found evidence that the weevil Euscepes postfasciatus (Fairmaire) (Coleoptera: Curculionidae) preferred green LEDs to the UV light traps.…”

“…However, more studies are looking into other wavelengths and their attraction to insects. Nakamoto and Kuba (2004) tested the effectiveness of green LEDs in light traps against the weevil Euscepes postfasciatus (Fairmaire) and made a case for using LEDs as opposed to more conventional UV lights. Chang et al (2001) looked at alate attraction of Formosan subterranean termite, Coptotermes formosanus Shiraki, to different light wavelengths and found that blue (367Ð583-nm) and green (525Ð 648-nm) lights attracted signiÞcantly more alates of this species than the red (600 Ð733-nm) lights and the control.…”
