2nd Generation Codling Moth in Higher Elevations, BMSB in Lower Elevations Codling Moth: In higher elevation orchards such as Henderson County, second generation codling moth DD accumulations average about 1512, compared to 2056 in lower elevation Cleveland County. The 1512 cumulative DD in Henderson correlates with about 15% egg hatch of the second generation. If not using mating disruption, now is an excellent time for insecticidal control of this generation. While pheromone trap captures should be used to judge population abundance and the need for additional applications, one application is usually sufficient against in low-population orchards.
