The effect of imidacloprid and fipronil on Sympetrum infuscatum larvae and adults during the rice cultivation period was monitored using an experimental micro-paddy lysimeter (MPL) system. Twenty-two hatched larvae were laid on the soil surface of each MPL. MPLs were treated with imidacloprid, fipronil, and the control MPL was left untreated. The pesticide(More)
The aim of the present study was to obtain quantitative information on egg hatching with respect to temperature and light to clarify the effect of cultivation methods on three Japanese Sympetrum species. Eggs of three Sympetrum species were collected on October 2005 at Akita prefecture located at north of Japan, and the eggs had been laid on soil surface of(More)
Among terrestrial arthropods, the dragonfly species Pantala flavescens is remarkable due to their nearly global distribution and extensive migratory ranges; the largest of any known insect. Capable of migrating across oceans, the potential for high rates of gene flow among geographically distant populations is significant. It has been hypothesized that P.(More)
Twenty-three polymorphic microsatellite markers for Sympetrum frequens were developed and characterized. The number of distinct alleles per locus in 32 individuals ranged from 2 to 23. The observed heterozygosity ranged from 0.031 to 0.938, while the expected heterozygosity varied from 0.031 to 0.922. No loci deviated significantly from Hardy–Weinberg(More)
