Abstract

A holidic diet which allowed the onion maggot, Delia antiqua (Meigen), to undergo complete development to the adult reproductive stage was developed. The effects of various concentrations of choline and salts on development were investigated. The amount of choline which gave optimal development was approximately 1/50 that used in most other artificial diets. It was found that the complex salt mixture (Wesson salts) normally used could be replaced by a solution of salts containing specific trace element ions (Fe, Mn, Cu, and Zn) and the two salts CaHPO4·H2O and KH2PO4.

Résumé

Un régime holidique permettant le développement complet de la mouche de l'oignon, Delia antiqua (Meigen), jusqu'au stade de l'adulte en reproduction a été mis au point. Les effets de différentes concentrations de choline et de sels sur le développement ont été étudiés. La quantité optimale de choline pour le développement s'est révélée être environ un cinquantième de celle utilisée dans la plupart des autres régimes artificiels. On a observé que le mélange complexe de sels normalement utilisé (sels Wesson) peut être remplacé par une solution de sels contenant les ions de certains oligo-éléments (Fe, Mn, Cu et Zn) ainsi que les deux sels CaHPO4·H2O et KH2PO4.
