Aphids in tunnel berries

This is just a short note to mention that aphids have popped up in tunnel strawberries at one of the research stations we work on. They haven't been problematic in our plots, and it takes a lot of aphids per plant (10 per newly expanded leaf on average as a rule). Aphids are, however, one of the pests that will likely be more problematic in tunnels than in the field. There are several conventional and organic options for aphid management when they do exceed threshold levels, but the strategy used for each will be different--early and often is the mantra for organic aphid materials, while conventional materials can and should be used much less frequently.
