First Insights on Early Host Plants and Dispersal Behavior of (Hemiptera: Pentatomidae) from Overwintering to Crop Colonization.

Following its first detection in North Italy in 2012, has become a serious threat in many crops, including hazelnut. The present study aimed at investigating dispersal capacity and behavior in relation to host plants of overwintered adults of before the colonization of hazelnut crop. Research was carried out in four polyculture areas (from 14 to 50 ha) in north-western Italy in 2018, by using (i) pheromone-baited traps, (ii) visual inspection and beating sheet sampling, and (iii) immunomarking-capture technique.
