Self-Medication as Adaptive Plasticity: Increased Ingestion of Plant Toxins by Parasitized Caterpillars
Figure 1
Percentage survival to adulthood of unparasitized and parasitized G. incorrupta caterpillars given a synthetic food lacking (PA−) or containing (PA+) 0.1% monocrotaline.
Survival of unparasitized caterpillars was significantly higher on PA− food, whereas survival of parasitized caterpillars was significantly higher on PA+ food (see text for statistics).
