UNDIGESTED UPTAKE OF NON-HOST PROTEINS BY VARROA JACOBSONI
NARESH C. TEWARSON AND WOLF ENGELS
Nutrition of the sucking mite Varroa jacobsoni includes macromolecular resorption of proteins. Undegraded Apis proteins can be detected in the blood and eggs of the mite by immuno-techniques. Uptake of proteinaceous molecules without digestion is not restricted to host proteins, as was demonstrated by the injection of bovine serum albumen into adult worker honeybees and its subsequent detection in the haemocoel of female mites which had fed on the injected bees for 12-48 h.
