| Outline of Final Research Achievements |
The effects of insecticides for paddy rice on paddy organisms were evaluated from individuals to biocommunity level. Neonicotinoid insecticide, Clothanidin, gave several negative effects to paddy biocommunity, and particularly caused a decrease of the amount of midges, dragonflies, and water fleas. Also, Nereistoxin insecticide, Cartap, indused several severe abnormalities on earlier development of frog embryo including Xenopus. The DNA microarray analysis suggested that disturbance of the genes expression related to morphogenesis and immune system was involved in teratogenic process of frogs.
