Codling moth larvae small caterpillar stage hatch in June and early July. They seek newly developing fruit, which they tunnel into, usually feeding in the center of the fruit and on the developing seeds. They feed on apples and pears, and even the related landscape plants quince, hawthorn, and crabapple. Affected fruits, if just with a bite on the surface, usually merely have a surface blemish.

One way of reducing pest damage therefore is to create an orchard habitat that encourages biodiversity and these natural enemies. Many pesticides will kill these beneficial species as well as the pests you are trying to control, which means your first line of defence is removed or weakened the next time the pest species attacks your fruit trees or crop.
For example, evidence shows that use of pesticides kills off the natural predator of red spider mite which is slow to recover, resulting in outbreaks of these as a result. The effect on natural enemies … would appear to be detrimental. The predator was unable to recover quickly enough to prevent a resurgence in pest numbers.
Even intensively managed orchards are now moving away from heavy pesticide use in favour of bio-control, mimicking the natural predator-prey relationships found in healthy orchard ecosystems to reduce damage to the fruit crop. This is often referred to as agroecology, the idea that you can reduce pest and disease damage by building in resilience through natural systems. Agriculture is more sustainable and resilient to change when it mimics biological systems. What we do know is that a biodiverse ecosystem is a more robust ecosystem, less at risk of high pest populations.
Many natural predators live in the canopy of your trees such as small soldier beetles, lacewings, earwigs, and hoverfly larvae, or ladybirds that overwinter in loose bark, which naturally help to control pests such as aphids. Wasps and hornets offer fantastic pest control in spring and early summer, being voracious predators of smaller insects to feed to their larvae. Wasps then have another role in the summer, particularly in cider orchards, whilst on their search for sugar, they inadvertently spread the wild yeasts required for cider to ferment.
Parasitic wasps have the reverse pattern; they act as pollinators in the spring and summer depending on the sugar rich wildflower nectar, then act as pest control in the late summer and Autumn when they parasitise pest species by laying their eggs within them. In this way parasitic wasps help regulate the populations of leaf mining moths and apple leaf midge among others.
Earwigs help prevent outbreaks of woolly aphid and also regulate the populations of other pest species. Both ladybird larvae and lacewing larvae are extremely efficient predators of aphids. Think holistically. The richer the botanical diversity of your orchard, the greater the array of insects it will sustain that act as pest control agents. This not only includes the plants on the orchard floor and in the hedgerow, but within your trees. Mosses and lichens on trees provide ideal habitat and protection for insects.
There are two main reasons for this:. This could be nesting boxes for birds if your orchard trees are not mature enough to provide suitable sites. It could also be nesting boxes for lacewings, ladybirds or earwigs. Earwig nesting sites can be made from tightly packed bundles of twigs and straw, protected from the elements however you see fit we find in a plastic bottle with the bottom chopped off works well and hung in your trees. Codling moth is a widespread and common pest of apple fruit.
The larvae burrow through the flesh into the core. They feed in the fruit for a number of weeks, excreting a wet dark-brown frass and spoiling the fruit. Eggs laid on leaves or fruit hatch and enter by the calyx eye , by the stalk or on the side of the fruit.Entry points on the fleshy side are more distinctive and detectable as it forms a prominent red ring around a hole that is often blocked by frass. Entry points at the stalk and calyx ends are more difficult to see, and can sometimes only be confirmed by cutting open the fruit.
After about 4 weeks inside the apple the larvae leave, spin cocoons under loose bark, in cracks in wood and in debris around the base of the tree, where they overwinter and pupate in spring. Codling moth is difficult to control once it is already in the fruit, so steps should be taken to reduce the larvae getting to the fruit.
A healthy ecosystem acts as a defence against outbreaks of pest species. There are many species that traditionally live in or visit orchards that will eat codling moth at every stage of development. Earwigs are predatory insects and a great ally of orchard owners, predating on codling moth eggs and young larvae.
Insect eating birds such as blue tits will also gorge on the larvae where they can, as will various beetles. Planting trees a good distance away from each other will help reduce the infection of other trees. Pests find it easier to spread in an overcrowded orchard. The flightless female moth will normally climb her tree of origin to mate and lay.
If you have a tree that suffers codling moth infestation annually, you can try a number of non-chemical controls. Wrapping bands of corrugated cardboard around the trunk from mid-summer offers an alternative place for moths to spin cocoons and overwinter.
Remove these every couple of weeks and burn them. Be aware that it will not only be codling moth larvae that use this as a nesting site, so only use this method on trees that suffer infestations. For any tree that is regularly infested with codling moth, remove the leaf litter and debris from under the tree.
This exposes the cocoons that are overwintering under the tree to predation. Chickens will scratch around under the trees; they will eat a good number of overwintering larvae so reducing infestation the next year.
Remove any infested fruit whilst thinning. This is only possible for young trees or lower branches of mature trees, but the removal of any larvae will reduce the scale of infection the next season.
Clear infested fruit as it drops. Infected fruit should be removed from the orchard, or the larvae killed by immersing the fruit in water for a week. Natural predators as pest control The species that act as pests in our orchards have natural predators and parasites. Natural predators and pesticides Many pesticides will kill these beneficial species as well as the pests you are trying to control, which means your first line of defence is removed or weakened the next time the pest species attacks your fruit trees or crop.
Encouraging beneficial predator species Apart from not spraying your orchard, there are other ways you can promote beneficial species. Keep the whole of your orchard botanically diverse. There are two main reasons for this: Many natural predators directly rely on nectar or fruit at certain stages of their life cycle.
Parasitic wasps and common wasps are good examples of this. Plant diversity increases the variety and number of insects in general, so you will be increasing the prey available for natural predators. This will help keep predator numbers high enough to tackle pest species and keep predators in your orchard even when pest numbers are temporarily low.
Provide additional nesting sites. Codling moth Codling moth is a widespread and common pest of apple fruit. Banding Wrapping bands of corrugated cardboard around the trunk from mid-summer offers an alternative place for moths to spin cocoons and overwinter.

Pest & Disease Control for Apple Trees
Local Local. Pears and apples are particularly susceptible to a fruit pest called the codling moth, and insecticide is required for all fruit growth residential and orchards within the Upper Grand Valley Pest Control District UGVPCD to limit damage that could be wrought on local fruit crops. This incentive program kicked off this month and will last until December. The district encompasses Clifton east to Palisade and parts of Orchard Mesa. Tree removal must also be carried out by landowners, not the county. Werkmeister additionally stressed that even a few untreated backyard fruit trees may cause damage to the local orchard business because pests move quickly and can easily get out of control.
garden reduces the risk of pest damage and can significantly reduce the need for pesticide treatments. Neglected fruit plants harbor many pests and should.
Integrated Pest Management IPM is a method of encouraging natural predators to control pests in your garden or orchard. Nature provides a balance between plant pests and the beneficial insects that control these pests. The less we do to tamper with that balance, the more likely it is to work successfully. How does it differ from organic gardening? Proponents of IPM are not opposed to the use of chemical controls, but use them only when necessary and only in amounts and with proper timing to minimize a negative effect on the beneficial bugs in the garden. Natural predators such as lacewings, leatherwing beetles, ladybird beetles, ground beetles, wasps, praying mantis and pirate bugs will control or contain most pest populations at an acceptable level, especially if trees are kept vigorous, orchard areas are kept clean of trash and weeds, and trees are well pruned to facilitate good air movement. Home orchardists have little need to completely eradicate pests. Most insect and mite pests of fruit trees are controlled by many beneficial species of insects and mites found in the orchard. Do not spray pests unless you are certain they are present in damaging numbers or this publication suggests you do so. Unnecessary sprays reduce control provided by beneficial species and may result in added damage from pests freed from their natural controls.
Peach Tree Borers
The following is a general guideline regarding when to spray for certain insects. Click here for a general overview of optimum spraying schedules. Oil based insecticides were developed for use during the dormant season, before the flower buds begin to open. This "dormant oil" kills off overwintering insects such as aphids, mites and scale, by virtually suffocating them because the oil blocks the spiracles through which insects breath.

How to Treat Fruit Tree Borers
A: Caring for fruit trees is a year-round job that includes pruning, fertilizing, removing diseased fruit, and spraying at different times of the year. Timing is critical for each of these tasks. During active growth, the trees absorb and use nutrients from fertilizers. To know when to spray fruit trees for pests, you first need to know what threatens the tree and when the threat is active. An insect egg can lie dormant in the bark of an apple tree all winter, only to hatch and feed on the leaves in spring. Or a particular fungal spore might infect a peach tree only while the flowers are open.
Dormant sprays kill overwintering insect pests on fruit trees. Unless pest populations spike, it is not necessary to spray dormant oil every.
Peach tree borers are serious pests of "stone fruit" trees, such as peaches, cherries, nectarines, apricots and plums. Adult peach tree borers don't harm trees directly; these moths simply lay eggs on stone fruit tree trunks. Damage comes when the moth eggs hatch and new caterpillar larvae travel down trunks and burrow into tree bases and roots, disrupting the flow of water and nutrients through the trees. Infestations of these trunk-boring caterpillars can kill stone fruit trees.RELATED VIDEO: Peach Tree Borers
This list of organic pest controls for fruit trees will help combat pests that attack orchard trees. Till recently even the most dedicated eastern organic orchardist has had to resort to powerful, indiscriminate insecticides from time to time—or lose a crop to the twin banes of fruit producers: the codling moth apple maggot and oriental fruit moth, whose brown-tunnel-making larvae ruin stone fruit. Now you can get Isomate-C to protect apples and Isomate-M for the oriental fruit moth. These are artificially produced sex pheromones—the chemical lures that females emit to attract males. A bargain!
In a garden orchard, fruit tree pest control requires some attention. When you plant a few fruit trees, you are offering an invitation to hundreds of different forms of life.
Pest Control. It is hard to beat the enjoyment of biting into a fresh, delicious, pest free delicious peach! The image of the Okanagan region is memorialized for its apples, peaches and tree fruits. More recently, it has become renowned for its wines, ciders and organic produce. Noxious pests are insects or related pests that are capable of devastating fruit bearing trees and shrubs in both residential and commercial plantings.Noxious Pests often lack natural enemies and can quickly take over plantings from single fruit tree in a backyard to an entire commercial orchard.
Commercial peach production in Florida would not be possible without effective disease and insect control. Although the peach fruit has a relatively short development period in Florida, the fruit as well as the tree is subjected to constant attack by a variety of pests. A good disease and insect control program is important, not only in protecting the maturing fruit, but in maintaining the trees' vigor season after season. Nevertheless, spraying for pest control is no easy task, and very difficult for the homeowner.
