| Abstract:
In some peach growing areas in Piedmont (Northern Italy), damages to fruits by Noctuid larvae were recorded in the last years. Damages were up to 40% of total yeld. The species involved were: Peridroma saucia, Mamestra brassicae, Axylia putris, Xestia c-nigrum and Diataraxia oleracea, with a greater abundance of Peridroma saucia, Mamestra brassicae and Axylia putris. Nocturnal inspections of the trees to find active larvae and monitoring with pheromone traps were poorly significant; ground examination gave data concordant with previous infestation on fruits. The orchards concerned had a grass cover, that was as high as lower branches of the trees, where damaged fruits were mainly found. All the species found are polyphagous and some of their host plants were present in the orchards concerned; this is probably one of the major factors influencing the attacks. | |
