Home orchardists have a few different options for controlling codling moths 
as we have seen from the various discussion over the past few weeks. We 
talked about using pheromone traps for monitoring to time insecticide 
sprays, or using them to "trap out" all the male moths. "Trapping out" is 
something that can work very well for the orchardists that have only a few 
trees.  This involves using enough pheromone traps such that all of the male 
moths are captured before the female moths mate. Female moths are then able 
to lay only unfertilized eggs that will not develop. Typically, 2 to 4 traps 
per tree are required for this to be successful. This is less effective if 
there are additional sources of mated females, such as other trees in the 
neighborhood or wild hosts.  To overcome this, the new CM/DA Combo Lure can 
be used to trap both male and female moths.  i think I stated earlier that I 
was involved in testing some of these CM/DA lures 2 years ago.  I use 
nothing but these now!

Traps should be put out at the pink stage of bud development. Every month, 
pheromone lures need to be replaced. If you are using the CM/DA Combo Lure, 
it will last for up to eight weeks.  I change mine out of my monitoring 
traps at 6 weeks.  Since you may also pick up other insects that 
inadvertently fly into the traps, codling moths can be distinguished from 
other insects in the traps by their bronze or copper colored wing tips.

For those needing only a few lures and traps and prefer to order over the 
internet, go to http://www.gemplers.com/insect-traps where you can find a 
host of IPM products.  They are just slightly more expensive than Great 
Lakes IPM, but you can order on the spot and get the order within a few 
days.  Hope this helps!
