June 12, 2017 – Our temperature sensors suggest codling moth degree day accumulation at 1063 with a possible second biofix which we will need to verify with additional trap data. We are still catching scale crawlers as of 6/12/17.
June 5, 2017 – Our temperature sensors suggest codling moth degree day accumulation at 943 with a possible second biofix which we will need to verify with one more trap check.
