The Electrode-Type Light Trap for the Collection of Moths

概要

For the purpose of standardizing the form of the light trap for surveying moth communities, the authors improved the baffled funnel trap by setting aluminum electrodes on the surface of the baffles. An efficiency test of this electrode-type light trap was carried out on the campus of the Sugadaira Montane Research Center of University of Tsukuba, Nagano Prefecture, Japan. The collected moths were sorted and counted, and the electrode-type light trap was found to be 3 times as efficient as the non-electrode custom type with respect to the number of individuals, and 1.79 times as efficient with respect to the number of species. There was no significant correlation between the effectiveness of the electrode-type and the body size of moths. However, it seems probable that the electrode-type is most effective for slender-bodied, weakly flying moths. This means that the electrode-type makes up for the disadvantages of the custom type light trap for these groups of moths.
