Abstract: 　Objective To study the changes in the content of elements in Aedes albopictus after dengue virus typeⅡ(DV2) infection. Methods DV2 were injected into the thorax of Ae.albopictus . The content of elements in Ae. albopictus was determined on days 5, 10 and 20 after infection respectively and compared with those in the same instar non infected mosquitoes. Results and Conclusion For the group of day 5 after DV2 infection, the content of elements Ca, S and Cr increased remarkably compared to those in the control group; while the content of elements Zn, Mo, Pb, Ce and Cl reduced remarkably. For the group of day 10 after infection, the content of Na, Mg, Zn, Se, Ce and S increased remarkably compared to those in the control; only that of Fe was lower remarkably than the control. For the group of day 20 after infection, the content of elements Ti and Pb increased remarkably than that of the control; while the content of Na, Zn, Cr and Ce reduced remarkably.
