On the Evolution of Host Specificity in Phytophagous Arthropods
We argue that generalist natural enemies of herbivorous insects provide a major selection pressure for restricted host plant range. The significance of plant chemistry is discussed in terms ofExpand

Self-Medication as Adaptive Plasticity: Increased Ingestion of Plant Toxins by Parasitized Caterpillars
Self-medication is a specific therapeutic behavioral change in response to disease or parasitism. The empirical literature on self-medication has so far focused entirely on identifying cases ofExpand

Diet-Induced Head Allometry Among Foliage-Chewing Insects and Its Importance for Graminivores
Individuals of the grass-feeding caterpillar of Pseudaletia unipuncta, reared from hatching on hard grass, had head masses twice as great as those of caterpillars fed soft artificial diet, evenExpand

When host choice is a problem for a generalist herbivore: experiments with the whitefly, Bemisia tabaci
1. Experiments with adult females of the whitefly, Bemisia tabaci, demonstrated that when mixtures of host plants were present, performance was reduced relative to that on the best of the host plantsExpand

Trade‐offs in host use by Manduca sexta: plant characters vs natural enemies
There are two principal native host plants for the sphingid moth Manduca sexta L. in south eastern Arizona: Datura wrightii (Solanaceae), and the more recently reported, nonsolanaceous host,Expand
