Notes: Pest control on pear primarily focuses on containing few species. Cydia pomonella is the most dangerous due to either suitable climatic conditions of the last decade or the occurrence of insect populations resistant to some of the most commonly used insecticides. Cacopsylla pyri and Quadraspidiotus perniciosus [Diaspidiotus perniciosus] are also among the most feared pests and are contained by means of specific chemical applications. Other species infest the pear orchard occasionally and insecticide applications are triggered by specific damage threshold. Some of them occur sporadically close to harvest (Lygus rugulipennis and Ostrinia nubilalis) or in orchards where environmental friendly pest control strategies are applied (Stephanitis pyri, Dysaphis pyri, Cossus cossus, Zeuzera pyrina, Euzophera bigella, Caliroa cerasi, Dasineura pyri, Anthonomus pomorum, Contarina pyrivora, Janus compressus and some mite species). Indications on the choice of insecticide and time of application are given.
