Summary

In the tickOrnithodorus moubata, the major protein of egg yolk, vitellin, was conserved in the guts of larvae and nymphs in aggregated forms for over four months after hatching. Vitellin was the nutrient which supported tick survival until the nymph could obtain a blood meal. This adds to the known role of yolk protein as the nutrient reserved for embryos a new role as a reserve for post-embryonic development and during starvation in the nymphal stage.
