Abstract

Haemolymph from Colorado potato beetles at larval, pupal, and adult stages was analyzed for pH, osmolality, and concentrations of magnesium, calcium, potassium, sodium, chloride, phosphate, and citrate. Differences in the concentrations of some ions observed between stages were used to formulate physiological saline solutions for the adult and larval stages.

Résumé

Nous avons déterminé la concentration en magnésium, calcium, potassium, sodium, chlore, phosphate, citrate, le pH et l’osmolalité du sang provenant de doryphores de la pomme de terre au stade larvaire, nymphal et adult. Des solutions physiologiques ont été développées pour le stade larvaire et l’adulte en tenant compte des différences de concentration de certain éléments.
