THE EFFECT OF MECHANICAL HARVESTING ON THE RASPBERRY CANE MIDGE, RESSELIELLA THEOBALDI

There were more larvae of the raspberry cane midge in primocanes of the red raspberry cultivar, Malling Jewel, damaged by the fish plates on a mechanical harvester than in primocanes from hand-picked rows.

There was little difference in the number of larvae occupying natural sites at the base of primocanes in hand-picked and machine-picked rows, but populations on primocanes in machine-picked rows were increased by larvae developing in fish plate wounds.
