One of the most important pest management practices growers can implement is montoring insect pest populations. This allows management pratices to be targeted when damaging populations are present and also provides a wealth of information about future pest populations.

We’ve posted lots of information about monitoring methods for insects in berry crops, including a series of “do-it-youself” (DIY) posts.

One caveat to our spotted wing drosophila (SWD) trapping recommendations-many new baits and lures are in the process of being developed for SWD. We no longer believe that apple cider vinegar is the most appropriate bait for traps. Instead, we are suggested that interested trappers use a mixture of 4 Tbsp sugar plus 2 Tbsp active yeast dissolved in 32 oz water. Traps should be filled 1 to 2 inches deep with this bait and changed weekly! After one week, yeast baits become unusable.
