The recent rain front and cooler conditions are likely to have slowed thrips development and kept adult thrips from flying long distances, reducing the chances of spread of any TSWV that might be present. The first generation of post-winter adults is expected to reach maximum numbers (i.e. "peak") today. Currently we are projecting that peak egg hatch for the second generation will occur around April 27th. The weather forecast for the week ahead is for temperatures in the mid to high 70s and no rain so we expect to see thrips activity begin to build. We are 5 days ahead of 2012 and 3 days ahead of the 30-year average for thrips degree day accumulation, indicating that thrips may be active relatively early this year.
