Abstract

The cigarette beetle, Lasioderma serricorne (Fabricius), is an important pest insect that consumes a variety of dry foods. It is known that UV light traps attract this species. However, less attention has been paid to its preferred wavelength. First, we investigated the spectral sensitivity of the compound eye. Next, we compared the attraction efficiency of LEDs of different colors (wavelengths). Our results showed that ultraviolet (UV, 375 nm) and blue (470 nm) LEDs attracted the most cigarette beetles of both sexes, irrespective of mating or oviposition status, although the UV LED consistently tended to attract the most beetles. Although the primary sensitivity peak of the compound eye was 520 nm, the green LED (520 nm) scarcely attracted beetles. Although the reason for the difference between the peaks in spectral sensitivity and attraction of beetles awaits further studies, whether UV and/or blue LEDs is more effective as a practical light trap for controlling L. serricorne beetle is discussed in this study.
