Conditions good for development of aphid infestations

Whilst there have been few Brevicoryne brassicae flying so far this year, conditions have been good for development of infestations on plants (warm and dry). Liam Harvey, one of our HDC PhD students infested his plots with Brevicoryne earlier on and the picture below shows what an impact they can have. The inner plants were infested, the outer plants were 'guards'.
