Yet more foreign pests, brouht in with consignment plants.by Malcolm Greenhalgh on 03/28/13
This time two very closely related species, the Asian and the citrus longhorn beetles, have arrived and are spreading. Their larvae feed on the heartwood of trees and shrubs and their tunneling weakens the plant, leading to death. The larvae have exit holes 6-11mm in diameter close to ground level. The adult beetles are unmistakeable: up to 37mm (1 1/2 inches) in lenght, with a black body with double white spots on the back and with very long, black and white banded antennae. Should you come across one, put it alive in a container for examination: these are notifable pests. The Food and Environments Agency (FERA) can be contacted on 01904 465625.
