Once hatched, the larva will head towards the center of the fruit, where it consumes the developing seeds. Be sure to remove any fruit that has small holes made by codling moth caterpillars. It is an ugly-looking snout beetle, or weevil, less than ¼ long as an adult, mottled tan and black, with bumpy knobs on its wing covers. Excellent control can be achieved by enclosing young fruit in Maggot Barrier bags right on the tree to protect them from the codling moth. Stings made in early spring are generally the sign of Codling Moth activity. A summer and fall clean up fallen apples is recommended. When the apples are ripe in the fall and drop from the tree, the worms crawl out and burrow into the ground. How else can I stop the worms? Contact Us | There is a visible exit hole if the larva has already left the fruit. The larva that will soon be looking for a spot to spend the winter and turn into flies and moths come autumn. Like all caterpillars, it has legs, which distinguish it from other kinds of larvae usually found infesting apples. Caterpillar worms, which are generally larger, will usually feed deeper—to the core itself. The caterpillars of this insect can damage a high proportion of the fruits on apple trees in gardens. Tour | Begin implementing control measures early in the season. The damage is at first only a pinprick, but the scars from these stings distort the shape of the apple as it grows, often leaving it lumpy and unattractive. The damage starts in the Spring when a moth known as the codling moth is busy laying its eggs at the base of your newly formed apples or pears and also on the leaves. Typically, after entering the fruit, the larva will tunnel into the core, where it feeds on the developing seeds for about three weeks. Unfortunately, the adults do not all hatch at the same time, so that monitoring must be carried out until the end of August. The period between the emergence of the adults and the hatching of the caterpillars is when the Codling Moth is most vulnerable. The core of an infested apple is usually filled with frass. The Apple Maggot is a creature of midsummer. Thinning when fruit is small (the size of a marble or walnut) so that there is only one apple or pear per fruit cluster is a good practice to encourage a larger fruit size and provide less optimal laying sites.
