Temporal modulation of pyrrolizidine alkaloid intake and genetic variation in performance of Utetheisa ornatrix caterpillars.

Abstract excerpt

Foraging on a variety of different food items allows individuals to balance nutrient intake, but it also may dilute toxins present in single items of the diet. The distinction between nutrient balancing and toxin dilution becomes less clear, however, for organisms that sequester potentially toxic compounds for their own benefit.
