摘要：

Radiocesium contaminations in Diptera (Muscidae, Calliphoridae) was investigated at three distances (11 km, 14 km, and 25 km) from the Fukushima Dai-ichi Nuclear Power Plant. The Cs134+137 concentrations in adults of coprophagous Musca hervei Villeneuve and necrophagous Chrysomyia pinguis (Walker) at an 11-km point were 3 and 2.8-4 times higher than those of a 14-km point, respectively. The Cs134+137 concentration in adults C. pinguis throughout three years from 2014 to 2016 with maximum 6886 Bq kg(-1) was significantly higher than that of M. hervei. In rearing experiments, eggs of uncontaminated Neomyia cornicina (Fabricius) and Lucilia caesar Linnaeus were inoculated onto cattle dung and meat samples (cattle and the Japanese monkey) contaminated with radiocesium. The Cs134+137 concentrations in pupae of N. cornicina reared from two contamination levels of dung samples were 217 +/- 4.9 Bq kg(-1) and 597 +/- 22 Bq kg(-1), respectively; those in pupae of L. caesar reared from two contamination levels of monkey meat samples were 55 +/- 4.3 Bq kg(-1) and 3390 +/- 55 Bq kg(-1), respectively. The Cs134+137 concentrations in adults emerged from pupae for cattle dung and meat suggest that most of the Cs134+137 in pupae transfer to adults during metamorphosis in cyclorrhaphous Diptera.
