The Apple Maggot Fly Can Use Hawthorn Berries Or Apples As Hosts. – Mature apple maggots begin to emerge from the ground around July 1 and continue through most of the summer.
Removing overripe and rotten apples around your trees can help reduce apple maggot infestations, but it won’t prevent apple flies from coming from other areas.
The Apple Maggot Fly Can Use Hawthorn Berries Or Apples As Hosts.
This method was developed in western Minnesota and should be used after thinning the fruit in early to mid-June.
How To Get Rid Of Apple Maggots In Your Apple Tree
Packing fruit takes extra time, but the apples are protected from apple maggots for the rest of the season.
Bagging is easy to do if you have a small to medium-sized tree that can be managed from the ground or a short ladder.
If you have a tall tree, you can choose to pack only the fruits that are easy to reach, and let the apple maggots grow the fruit higher.
Whatever type of trap you choose, the bulbs or apples should be at least 3 inches in diameter and bright red.
The Rise Of The Apple Maggot Fly
If there are apple or hawthorn trees in wooded or landscaped areas nearby, you may want to hang traps in these trees as well, to further reduce apple moth pressure.
Kaolin clay can discourage apple flies and other insects from laying eggs in apple plantings. This method is best used with traps and before any pesticide application.
Check for the presence of apple maggots using sticky red orbs. This will help you decide if you should use a pesticide.
Fortunately, the number of adult apple moths decreases as the season progresses and you should be able to stop spraying sometime in August.

NOTE: Pesticide listing or use of a pesticide label is for educational purposes only. Always follow the directions on the pesticide label attached to the pesticide container you are using. Make sure the plant you want to treat is on the label of the pesticide you want to use. And observe the number of days between pesticide use and when you can harvest your crop. Remember, the label is the law.

Apple maggots can ruin an entire crop, leaving you unsure of what to do. Learning to recognize the signs and taking the right preventive measures in advance is essential to combat these pests.
While apple trees are the main host for apple maggot pests, they can also be found in any of the following:
While other worms that affect apples can be confused with these pests, you can usually tell them apart simply by taking a closer look. Caterpillars, which are generally larger in size, will usually feed deeper – right down to the core itself. Apple maggots, the small, about ¼ inch (6 mm.), larva of fruit flies and resemble maggots, usually feed on the flesh and tunnel through the fruit.

Evidence of apple maggots can be seen as small pinpricks or dimples in the skin. In addition, affected apples will begin to rot quite quickly, becoming soft and rotten before falling from the tree. As the maggots grow and tunnel, you’ll see the telltale brown trails winding through the fruit when cut open.
The best way to prevent attacks is to keep things tidy by picking apples regularly, especially those that fall from the tree. Unfortunately, once infested, the only treatment is chemical control, which normally targets the adult fruit flies.
The specific types and availability of apple mite control products can usually be obtained through your local county extension office. Affected trees are sprayed from about mid-July until pre-harvest with continuous applications, according to product instructions, or mixed with 3 cups (710 ml) of kaolin clay for every 1 gallon (4 L.) of water every seven to 10 days.
Another apple moth control product that is more natural is kaolin clay. This is often used as a preventative measure as it creates a film on the fruit that insect pests find irritating. As a result, they tend to avoid trees/plants that have been treated with kaolin clay. Spraying should be done mid to late June and reapplied every seven to 10 days. Be sure to saturate the tree completely.

To prevent these pests, apple fly traps are also available. These can be purchased at most garden centers or through agricultural suppliers. Apple fly traps are usually set in the spring (June) and followed throughout the fall (September). Set a trap in trees less than 2 m high and about two to four traps in larger trees. Traps should be cleaned weekly and may need to be replaced monthly.
Another idea to catch the apple worm is by using homemade methods. For example, you can take some red balls (styrofoam works well) – about the size of an apple – and cover them with a sticky material, such as molasses. Hang these fake apples from the tree (about four to six per tree, depending on size) at shoulder height. This should attract the fruit flies, which stick to the balls and are immediately thrown away when full.
You can also mix 1 part molasses with 9 parts water with a small amount of yeast. Pour this into several wide-mouth jars and let them ferment (ready once the bubbling is gone). Hang the jars on the strongest limbs and the fruit flies will get trapped inside. flies, and a plague of various fruits, especially apples. This species evolved about 150 years ago through a sympatric shift from the native hawthorn to the domesticated apple variety Malus domestica in the northeastern United States. This fly is believed to have accidentally spread to the western United States from the demic eastern region of the United States via infected apples at multiple points in the 20th century. The apple worm uses Batesian mimicry as a defense method, with a color similar to that of the front legs and pedipalps of a jumping spider (family Salticidae).
The adult form of this insect is about 5 mm (0.20 in) long, slightly smaller than a housefly. The larva, the stage of this insect’s life cycle that does the actual damage to the fruit, resembles a typical fly larva or maggot. Caterpillars, especially the codling moth larvae, which infest the insides of apples, are often confused with the apple worm. However, these organisms generally feed on the core of the apple while apple maggots feed on the pulp. The larvae of the apple maggots are often difficult to detect in infected fruit because of their pale, cream color and small body size. The adult fly lays its eggs in the fruit. Larvae consume the fruit and cause it to bruise, decay and eventually fall before it ripens. The insect overwinters as a pupa in the ground. It only appears after metamorphosis into a relatively defenseless fly. Adults appear from late June to September, with their peak flight times in August.
Are Apples With Maggots Safe To Eat? The Health Risks Of Eating Maggots
From USDA. A: Female fly B: Eggs removed from apple C: Egg holes in apple skin D: Eggs in normal position in apple E: Larva, almost fully grown F: Pupae.
Eggs are spindle-shaped and pearly white when laid in the fruit, but after a short time in the fruit they turn cream-colored. Clearly developing larvae can be seen in the translucent eggs.
The larva is white or cream colored, but if it eats gre pulp near the fruit skin, the gre is visible through the skin. Larvae range in length from 7 to 8.5 mm and in width from 1.75 to 2 mm.
The pupa is formed in the larval skin, after the maggot strikes shorts and becomes inactive. During the pupal stage, the larva is initially light yellow, but turns yellow-brown within a few hours and in the dark. The pupae vary in length from 4 to 5 mm and in width from 2 to 2.5 mm and have an elongated oval shape.

Adult female R. pomonella are glossy black with white markings and an average length of 6.25 mm. Their wingspan is on average 12 mm. They have gray eyes and a white stripe on each side of the thorax. The belly is glossy black with four uniform white bands. When not in use, the ovipositor is fully retracted into the abdomen. The ovipositor is horn-like, hard and chitin-like. Male R. pomonella have a similar appearance to the females, but are smaller with an average length of 4-5 mm; the size of the abdomen is the main difference, with only five of the sev segmts visible (the sixth and sevth are retracted below the fifth). The sixth and seventh segments contain a chitinous framework that supports a long, spiral (coiled) chitinous piss, which is closed by a spiral brush with numerous stiff bristles.
Rhagoletis pomonella is common in North America, although it is only found in the eastern United States. The apple variety’s range falls within that of the hawthorn variety, including the Northeast and Midwestern United States and eastern Canada.
The species has been found as far south as Florida. 1979,
