Pheromone traps, degree-days, and sunset temperatures are used to determine egg hatch and proper spray timing for control of codling moth. In spring, degree-days should be accumulated from the first date that moths are consistently found in traps and when sunset temperatures have reached 62°F. This date is the first biofix, and is used in conjunction with accumulated degree-days to time sprays for effective control of the different generations of codling moth.
