Squamura, Heylaerts, 1890

Symptoms of Squamura View in CoL damage in host trees

Thirty trees of each species from from which Squamura adults were reared were selected to investigate the morphology and distribution of tunnels within the bark and sapwood. Trunk and branch surfaces were examined to locate the number of tunnel entrances and document their length and diameter. To describe chambers, the bark or sapwood around larval and pupal chambers was carefully sectioned and opened. To characterize chambers inside the branches, damaged branches of each tree were removed and dissected (one branch per pest species per tree).
