| Abstract:
In the present paper, results are reported of studies carried out in Italy on some species of Psyllids which infest urban trees. Particular emphasis is given in illustrating the life cycle and natural enemies of Cacopsylla pulchella (Löw), living on Juda's Tree, together with bio-ecological information on the elm psyllid [Cacopsylla ulmi (Förster)] and two oak-feeding psyllids of the genus Trioza. Notes are also provided on species living on acacias [Acizzia acaciaebaileyanae (Froggatt) and A. uncatoides (Ferris and Klyver)], ashes (Psyllopsis spp.), Maple [Rhinocola aceris (L.)], Italian Alder (Psylla cordata Tamanini) and on a few secondary species. | |
