  1. The insecticide resistance screening for Waimea and Kula looked good in 2011. The next DBM assay has been set for June 2012. The moon calendar suggests favorable pupae field collection times during May 28-31. Keep your back and eyes in shape for another round--lots of stooping, searching and working with tiny caterpillars.
