Influence of banker plants and spiders on biological control by Orius insidiosus (Heteroptera: Anthocoridae)

► Banker plants did not improve biological control by Orius insidiosus. ► Pollen, as alternative food, did not reduce predation by O. insidiosus. ► Spider colonized banker plants reducing O. insidiosus access to pollen. ► Banker plants appear best suited for indoor greenhouse crops.
