Briefly describe the biology of codling moth?
The codling moth overwinters as a mature larva beneath tree bark scales or at the base of the tree. Adults appear about full bloom of Red Delicious apples and eggs are laid on leaves or developing fruitlets. Eggs hatch in 10 to 25 days, depending upon temperature, and the young larvae move to developing fruit within a few hours, chew through the skin, and burrow into the flesh. Subsequently, the larva burrows to the fruit core and feeds on seeds. After 25 to 40 days, the larva is mature, exits the fruit, spins a cocoon, and pupates. Moths of the second generation emerge two to three weeks later.
