Food and Trophic Relationships

Insects have evolved diverse feeding habits that allow them to exploit virtually every naturally occurring organic substance. Among their adaptations are specialized ingestive and digestive systems, the ability to detoxify or physically avoid toxins produced by the host, mutualistic relationships between the insect and microorganisms, and life-history strategies that result in temporal avoidance of resource-poor situations (including those resulting from interspecific competition) or times when the host's toxins are abundant. Thus, insects participate in an array of trophic interactions as herbivores, predators, parasites, parasitoids, detritivores, and prey in both terrestrial andfreshwater ecosystems (Figures 23.1 and 23.2). Food may be an important limiter of insect population growth; it may also affect the distribution and the dispersal of species over time (Price, 1997).
