ASPECTS QUANTITATIFS DES BESOINS EN MINÉRAUX DES LARVES DE TRIBOLIUM CONFUSUM DUVAL: I. POURCENTAGE OPTIMUM D'UN MÉLANGE SALIN

Abstract

The quantitative requirements of the larvae of Tribolium confusum are studied. For optimal growth, the larvae require 1% to 8% of salt mixture No. 2 U.S.P. XIII. For the imaginal metamorphosis, we must add at least 2% of the salt Mixture. The requirements of the male and female are absolutely identical.
