Effects of Intraspecific Genetic Variation and Prior Herbivory in an Old-Field Plant on the Abundance of the Specialist Aphid Uroleucon nigrotuberculatum (Hemiptera: Aphididae).

Abstract excerpt

Intraspecific genetic variation in plants can contribute to the diversity and abundance of associated insects, though many questions remain about why some genotypes support more insects than others. Since plant secondary metabolites, which may be induced after insect attack, may potentially vary among genotypes, these compounds provide a possible explanation for insect abundance variation in plants with...
