抄録

<p>Aquatic insects in paddy fields collected using underwater light traps were investigated in Fukushima prefecture. 10, 118 individuals（6 orders, 18 families）were collected from 2008 to 2011 in six areas. Using underwater light trap was more effective than dipping a D-flame hand net for individual collection in seven taxa: Guignotus japonicus, Noterus japonicus, Peltodytes intermedius, Hydrophilidae spp., Ranatra chinensis,Microveliinae spp., and Baetidae spp.. For the six taxa: Lissorhoptrus oryzophilus, Notonecta triguttata,Sigara spp., Appasus spp., Zygoptera spp., and Trichoptera spp., no significant differences were found between the use of light traps and that of hand nets. Seasonal changes in the number of several species were apparent in the case of using underwater light traps. These results indicate that underwater light traps are effective for surveying biodiversity in paddy fields.</p>
