Resumo
In this study, multielemental analysis of Lonomia obliqua (Lepidoptera,
Saturniidae) caterpillar was performed using energy dispersive X‐ray fluorescence
and instrumental neutron activation analysis techniques. This caterpillar
is poisonous and has the ability to cause fatal hemorrhagic effects in humans
after contact. The need of this study is related to morphological changes
(mainly size and color) observed in some caterpillars used for preparation of
antilonomic serum (antivenom). The samples were classified as healthy (caterpillars
of control) and unhealthy (caterpillars visibly modified). The XRF measurements
were performed in an energy dispersive X‐ray fluorescence
spectrometer and the instrumental neutron activation analysis using the IEAR1
nuclear reactor at IPEN. The results show significant differences for several
elements (mainly, P, Cl, Ca, Ti, Mn, Fe, Ni, and Zn) in unhealthy caterpillars
that can affect the development of this species as well as the quality and yield
of the antivenom. Furthermore, its elemental characterization contributes for
the understanding the potential pharmacological (procoagulant and antithrombotic)
in the prevention of life‐threatening blood clots.
