Abstract

Ion induced X-ray fluorescence was used to analyze adult and immature stages of Solenopsis richteri Forel and S. geminata (F.) for total body concentration of 16 major and trace elements. Results indicated that P, S, Cl, K, Ca, Ni, Cr, Ti, Fe, Cu, Zn, Mn, Pb, Sr, Mo, and Rb could be detected in ashed samples of major and minor workers, pupae, and larvae. Multi-elemental analyses among 3 developmental stages in each of the 2 species indicated that adults contained a greater relative concentration of major and trace elements when compared to the immature stages. In addition, the following trend concerning the total body elemental concentration was generally observed: workers > pupae > larvae.
