The use of mirids and anthocorid bugs as polyphagous predators in greenhouse crops

Abstract: Polyphagous predators have shown to be a viable solution for IPM programs in vegetable crops. In this paper advantages and disadvantages of using polyphagous predators are discussed. We also summarize existing experiences on the use of refuge plants to implement conservation programs. Recent experiences conducted by our group for the conservation of mirid and anthocorid bugs in tomato and lettuce Mediterranean crops are explained. The presence of refuge plants in the crop margins can increase the abundance of those polyphagous predators, advance their presence in the crop and facilitate their establishment, contributing to control crop pests, besides to be also beneficial to other neighbouring vegetable crops.
