| Research Abstract |
(1) We applied the identification of the trace element by the activation analysis to the insects for the first time. The results revealed that several trace elements which are common to both a target insect, Culex tritaeniorhynchus, and soil of its habitat were identified from a total of 24 representative elements.(2) We used synchrotron radiation to an adult mosquito in large-scale emission light institution(SPring-8) in Harima, Hyogo, and carried out a preliminary experiment of analysis of trace elements contained in mosquito body. The X-ray imaging using X-ray fluorescence microscopy was also carried out. These results revealed the more detailed information of trace elements composition contained in an adult mosquito and indicated the elemental distribution in each part of the mosquito body with a scanning of X-ray microprobe.
