Effects of different artificial diets on commercial honey bee colony performance, health biomarkers, and gut microbiota.

Hives are routinely fed artificial "pollen substitute" diets to compensate for insufficient nutritional forage in the environment. The aim of this study was to investigate the effects of different artificial diets in a northern California, […]
