1 Elatobium abietinum (Walker) is the most important defoliating pest of Sitka spruce Picea sitchensis (Bong.) Carr. Climate change in the U.K. is predicted to increase incidences of spring–summer drought events, with the aphid expected to respond to these changes. This will have serious implications for damage levels and growth of infested Sitka spruce, as well as control of the aphid pe…
