Exploitation of predators in UK fruit and hop culture

A wide range of species of predators has been exploited, or has the potential to be exploited, as biological control agents against pests of fruit and hop. They include members of the families Miridae, Anthocoridae and Chrysopidae, and of the mite family Phytoseiidae. Some species can colonise fruit plantations naturally, whereas others are mass-cultured and introduced artificially. The characteristics of the various predator species are considered in relation to the requirements for biological control agents in specific crop situations.
