What is Impact and control of the cone tortricid Pseudococcyx tessulatana (Staudinger), damaging the cone crop of a selected clone of cypress ( Cupressus sempervirens L.) in Italy about?

## Abstract The green cypress (__Cupressus sempervirens__) is of great interest for ornamental, reforestation and windbreak use in the whole Mediterranean basin. In Italy, seed material selected for resistance to the fungus __Seiridium cardinale__ is produced in seed orchards by controlled crosses of parent trees. The insect pest showing the highest impact on seed cone production is __Pseudococcyx tessulatana__ (Lep.; Tortricidae), which attacks cones during the initial growth period as well as full‐grown cones. The impact on the seed cone crop of the tortricid was estimated on a clone patented for its resistance to cypress canker (Agrimed 1). The attack was inversely related to the cone crop, as it concerned 36.7 % of cones in 1999 (high crop year) and the 66 % in 2000 (low crop year). In both years, about 90 % of the surveyed branches revealed cones attacked by __P. tessulatana__ by the 1^st^ life‐cycle larvae, whereas only 40 % of branches were also attacked by the larvae of the 2^nd^ life cycle. The highest attack rate per branch was always observed on branches bearing a low number of cones. The potential of two control methods against __P. tessulatana__ to protect cones which
