WebHerbivores are dependent on plants for food, and have coevolved mechanisms to obtain this food despite the evolution of a diverse arsenal of plant defenses against herbivory. Herbivore adaptations to plant defense have been likened to "offensive traits" and consist of those traits that allow for increased feeding and use of a host. Plants, on the other hand, … WebMany insects depend on their facultative symbionts to increase their survival against com-mon threats, and an increasing number of mutualistic microbes have been shown to provide protection [6–8].
