Mass production of predatory mites: state of the art and future challenges

Abstract: Predatory mites, and phytoseiids in particular, are among the most important
biological control agents used in integrated pest management. The ability to mass-produce these predators at high density on inexpensive food sources is a key driver of their success. Here, we provide an overview of the rearing systems currently in use by biocontrol producers. Moreover, we discuss the biotic and abiotic challenges that are associated with the rearing systems. Finally, we highlight possibilities for further improvement of the efficiency of mass production of predatory mites.
