First record of Tinocallis ulmiparvifoliae in Italy on bonsai plants

In spring 1994, in the Province of Bologna (IT), a new aphid pest has been found repeatedly on bonsai plants of Ulmus parvifolia, in garden centres and nurseries. This aphid has been identified as Tinocallis ulmiparvifoliae which originates from Japan, Korea and China. It is also present in Taiwan and Australia. The authors recalled that T. ulmiparvifoliae has been also recorded in 1973 on bonsai elms in England. This aphid causes a progressive yellowing of the leaves, followed by leaf drop. It produces also large quantities of honeydew which favour the development of sooty mould on the leaves.
