Codling moth degree day (DD) accumulations since biofix range from about 1660 in Henderson County to almost 2000 in Cleveland County, which coincides with second generation egg hatch of about 30% and 70% completion, respectively. In orchards not using mating disruption, an insecticide application effective against codling moth (Altacor or Delegate, whichever was NOT used against the first generation) should have been recently applied. Overall codling moth pressure has been fairly low in most orchards, so a single application is probably sufficient in many locations. If you are unsure of your population density, two applications at 14-day intervals are recommended. In orchards with very low codling moth pressure, as documented by low pheromone trap captures, other insecticides may also be considered, including Assail and Intrepid.
