Understanding the behavior of spider mites as well as the predaceous mites is significant for successful biological control. Dispersal behavior of different predatory mites will affect how well they control different types of infestations. Generalist mites move around individual plants more, whereas specialists cover an over all broader area. Herbivore-induced plant volatiles have effects on both spider and predacious mites.
Various behaviors occur in response to conspecific and heterospecific competitors.
There are certain advantages or disadvantages in selecting a plant already inhabited by conspecific or heterospecific competetors. This needs to be considered before release of predatory mites. Mites can be either feeding, resting, or moving. The allocation of these behaviors is significant to the interactions of plant, prey, and predator. The amount of time spent doing each activity by spider and predacious mites of various ages is discussed.
