The following information is provided by Dr. Ramesh Pokharel, Western Colorado Research Center, Orchard Mesa Station.
Mesa County:
Codling moth is active, and you need to protect your crops from this pest by pesticide applications. (Please remember not to repeat the same chemistry of pesticides more than twice).
Peach twig borer moth (PTB) was captured in our trap on May 25 at WCRC-OM site. June 15-18 is the recommended period for the first cover spray for this insect.
Western Cherry fruit fly (WCFF) should be flying in the area by now and you need to spray your cherry to protect from WCFF.
Delta County
At Rogers Mesa, Delta County: Codling moth (CM) biofix occurred at about May 7. This is the right time to put your first cover spray for CM management.
At Rogers Mesa site, we have no record of other insects in our traps. However, you need to watch for PTB moths and western cherry fruit flies as this is the right time to observe these insects flying according to our DD model. If it is so, schedule your spray at around June 17-18 for PTB and June 5-6 for WCFF.
For more details on these fruit tree pests and sprays needed check out :

For Cedaredge, the biofix for codling moth (CM) was projected at around May 17-18. Then the first cover spray for CM should be scheduled for June 5-6 if you are scheduling to spray at 150 DD days, and the spray date should be June 10-11 if you are spraying at 250 DD of biofix. PTB is expected to fly from June 8 then you need to schedule your first cover spray at around last week of June or early July. Western cherry fruit fly is expected to start flying from June 11, and the first cover spray should be done around June 13-14.

Fruit tree pests still need to be controlled
In today’s fruit tree update by Dr. Ramesh Pokharel, Western Colorado Research Center the following treatments are recommended.
“Codling moth (CM): We are still catching substantial numbers of second generation moth in our traps. It suggests us that we need protection against this pest beyond August 1. You also may need an additional spray beyond August 1 depending upon the activity of moths, the protection window of your insecticide used and harvesting date.
Peach Twig Borer (PTB): We are catching higher numbers (more than previous weeks) of second generation PTB month in our traps. This suggests a need to protect crop against this generation. Control of this generation is important as this generation can feed on fruits.
Crown Borer: The Crown borers are active in our orchard. Please, remember to have two sprays (a cover and a follow-up spray) to protect your crop from this pest. If this borer is active even after second spray, we might need a third spray during fall (trunk spray). Keep eye on this pest.”
To ensure good quality fruit and the survival of your fruit trees, treatments for these pests need to be applied and/or continued. Information on these pests and their control is available at http://www.ext.colostate.edu/pubs/garden/02800.html and http://www.ext.colostate.edu/pubs/garden/02804.html .

Fruit Tree insect Spray Needs
Mesa County:
Apple and Pear - The Codling moth is the insect in this area that causes wormy fruit. Thankfully we do not have the biostrain of apple maggot that cause so much trouble back east and in other parts of the nation. The first spray for the codling moth should have been applied within 10 days of full bloom. The second generation codling moth flight is expected on June 19 and an insecticide needs to be applied by that time.
The Peach Twig Borer causes damage to the fruit of peach, plum and apricot and causes new shoots on these trees to wilt and die. The first spray for this insect should be applied between June 10-15.
Western Cherry Fruit Fly: Based on the available information from Fruitvale and Redlands, it is time for the cover spray for this insect, especially in those areas.
Delta County:
Rogers Mesa
Apple and Pear - The second generation of the codling moth is expected on July 2-3. A spray should be applied by that time.
Peach, Plum and Apricot – The Peach Twig Borer spray should be applied between June 17-21.
Cedaredge
Peach, Plum and Apricot – The spray for the Peach Twig Borer should be applied between June 19-24.
