In a fair world, hot weather would be as hard on the insects that attack fruit trees as it is on the trees. Unfortunately, the wormy apple culprit, codling moth, thrives in hot weather. In fact, most of Western Montana’s fruit tree pests like warm weather.
Insects have relatively predictable cycles from egg to larval to adult stages. Insects are bound to “physiological calendars”, based not on time, but instead on temperature and moisture. Codling Moth is partial to temperatures above 50 F. When temperatures consistently reach 50 F, Codling Moth adults emerge, mate, and lay eggs near or on developing apples. After a specific time period at 50 F, these eggs hatch and in 4 – 48 hours, tiny white Codling Moth caterpillars tunnel into apples. Then, these worms we hate to find as we crunch into our first home-grown apple are home-free. Bird and insect predators, as well as our sprays can’t touch them. Timing is everything! Timing Codling Moth control requires monitoring. We can use pheromone traps to catch the first emerging male moths. Pheromones are a little like insect perfume; they help male Codling Moths find female Codling Moths. Fortunately for gardeners, male Codling Moths will follow synthesized pheromone right into the sticky traps we use to monitor them. Remember that pheromone traps ONLY CATCH MALE MOTHS! PHEROMONE TRAPS DO NOT CONTROL FEMALE, EGG-LAYING CODLING MOTHS. When we catch the first Codling Moth, we start our 50 degree temperature clock and measure until a specific number of hours above 50 F have passed. This gives us the window for Codling Moth hatch and first spray timing. The warmer it is, the more quickly the Codling moth development hours accumulate. So, the first Codling Moth spray-timing window may be earlier this year. Models predict the egg hatch to start between end of May -first week of June.
It cannot be stressed enough that CM controls must be applied at the right time to affect the targeted life stage, otherwise the efforts will have little impact, may harm other wildlife, and time and products will be wasted. Keep in mind that any single method is unlikely to succeed on its own (aside from fruit bagging), so choose a combination of methods to implement throughout the CM season. Also recognize that CM is here to stay, and its management will always a part of raising crops susceptible to infestation.
There are many choices of control methods: bagging apples with a mesh bag, trunk banding, spays such as Spinosad, pyrethrin, malathion, carbaryl, and more. It’s good to rotate different kinds of sprays to insects don’t build a resistance to one spray. You will continue to spray as often as your label indicates till the end of August. You can check the Missoula County Pest Alert Hotline at 406-258-3820 for when to spray for codling moth.
