Studies on insect biochemistry. XI. Trace elements in the metamorphosis of Malacosoma neustria

Abstract
A semiquantitative spectrographic analysis is carried out, with bow arch excitation of the ashes of the three phases of evolution and of the cocoons of Malacosoma neustria.
The order of concentrations of the bioelements found in the samples is the following:
Larvae: P — Mg =s Ca > K > Si > Fe > Na > Al > Ba > > Sr > Mn = Ti > Cu > B > Cr. Not fount Be, Li, Ni.
Chrysales: P — Mg — Ca > K = Fe = Al > Na = Ba > > Sr > Si > Mri > Cu > Ti > B > Cr. Lacking Be, Li, Ni.
Butterflies: P — Mg — Si Ca > Fe = Na > K = Al > > Ba > Sr > Ti > Mn > Li = Cu > B > Ni > Be = Cr.
Cocoons: P Ca > Fe = K = Al = Mg > Na = Si > Sr > > Ba > Mn = Ti > Cu > B > Cr. Not found Be, Li, Ni.
