Butterfly mutation caused by Fukushima nuclear acc

Xinhua news agency, Tokyo, August 11 (LAN Jianzhong) - the research team led by zhanger Otaki, an associate professor of Ryukyu University, found that a local butterfly in Fukushima Prefecture had genetic abnormalities due to the radiation leakage from the Fukushima Daiichi nuclear power plant

this butterfly is called sorrel grey butterfly, which often appears on the edge of grass and trees near people's living places, and its adults can be seen all year round

in March last year, the Fukushima Daiichi nuclear power plant suffered a serious nuclear leak due to the damage of the earthquake and tsunami. In May and September of the same year, the success of the study that there was a product of ipwan in Europe, Asia and Latin America that could help the trial sale of mixed glass and nylon proved that this was a miracle. The team collected sorrel grey butterflies in Fukushima Prefecture, Ibaraki Prefecture, Tokyo and other places. Keeping improving, they let 144 sorrel grey butterflies collected in may lay eggs and hatch larvae after removing broken specimens. In the process of breeding these larvae, it was found that the mortality rate of the offspring of sorrel grey butterfly in Fukushima Prefecture, such as iwaki and Hirono, was higher than that in other regions, and the higher the radiation dose, the smaller the size of the male butterfly's wings

in the offspring of sorrel grey butterfly in Fukushima Prefecture, about 20% of the wing color matching and the number of spots were abnormal, and the frequency of abnormality was 1.5 times that of its parents. About 50% of the offspring of about 240 adults collected in Fukushima Prefecture in September showed similar abnormalities

for comparison, the research team conducted a low-dose irradiation experiment with the Kojima sorrel butterfly, which was considered to be almost unaffected by the Fukushima nuclear accident, and the same abnormality occurred

in the latest issue of the scientific report, Otaki and others published an article saying that the Fukushima nuclear accident undoubtedly had an impact on the surrounding environment. Although insects are considered to have strong resistance to the impact of low radiation doses, this investigation shows that the resistance of sorrel grey butterflies is low
