Describes a quantitative framework that may be used for understanding the effects of inducible plant defenses on herbivore populations. Procedures were used for modeling continuous, structured populations to examine the dynamics of interactions between inducible defenses and mobile herbivores. Inducible defenses can by themselves regulate herbivore populations under a wide variety of conditions and, in conjunction with other regulatory agents (eg predators, parasitoids), they can significantly depress herbivore populations. However, only under unusual conditions can inducible defenses cause persistent fluctuations in herbivore populations. The model suggests that herbivores cannot maintain heterogeneity in the level of inducible defenses within a plant population. Conclusions may not apply to sedentary or selective herbivores or to herbivores with discrete, nonoverlapping generations. -from Authors
