Rhagoletis completa is one of the major pests of nuts in the area of Bleggio (Trento province). In this area, the biology of this carpophagous insect was studied from the summer 2013 through 2015. Adult presence was checked using yellow sticky traps; oviposition and larval presence were observed on the fruits still on the plants and after harvest. The evaluation of efficacy of the product tested was done at harvest, first on the nuts fallen in the nets and then after the removal of the husk. Nuts were then classified in three groups according to damages. The study allowed to establish first emergence, flight period, oviposition beginning, larval hatching as well as a first evaluation of the control strategies. The research can be considered as a starting point for the control of the pest in field.

Abstract
Rhagoletis completa is one of the major pests of nuts in the area of Bleggio (Trento province). In this area, the biology of this carpophagous insect was studied from the summer 2013 through 2015. Adult presence was checked using yellow sticky traps; oviposition and larval presence were observed on the fruits still on the plants and after harvest. The evaluation of efficacy of the product tested was done at harvest, first on the nuts fallen in the nets and then after the removal of the husk. Nuts were then classified in three groups according to damages. The study allowed to establish first emergence, flight period, oviposition beginning, larval hatching as well as a first evaluation of the control strategies. The research can be considered as a starting point for the control of the pest in field.
