Fruit mites, photo and description
They are among the most common pests of garden trees. Due to the specific piercing-cutting mouth apparatus, the mites pull juices from the leaves, which leads to wilting and dropping of the latter, the affected fruits become smaller and wrinkle.
Severe infestation of the garden can result in the loss of more than a third of the crop.
What an apple red tick looks like can only be seen in a photo or under a magnifying glass, because it is very small in size, the length of an adult is 0.3 - 04 mm, males are smaller than females.
It is a polyphage, it can feed on the sap of representatives of different plant families: rosaceous, elm, beech, birch, walnut. It affects all fruit trees, roses, houseplants.
It can reproduce by bisexual and parthenogenetic means. The number of generations per year is:
- 7-9 generations in warm climates;
- in cool conditions - from 3 to 4.
The female lays from 60 to 150 eggs per season. Only eggs laid by females hibernate. Adults and larvae die with the onset of winter.
Reproduction, development, nutrition of the red apple tick occurs at a temperature of about +21 C, development stops at a temperature of + 8 C.
The life of an arachnid pest consists of 4 stages:
The body shape of adults is oval, the color is from light red to cherry, there are black spots on the sides. Eggs and larvae have a red color of varying intensity. At the nymph stage, they acquire a yellowish brown or reddish brown color.
They lead a sedentary lifestyle, high survival rate is ensured by the ability to adapt to the most extreme conditions of existence in any of the climatic zones.
Let's watch an interesting video about the red apple mite:
Symptoms of defeat
You can notice the presence of a red apple mite on trees by the appearance of numerous light spots on the affected leaves. They are especially noticeable near the veins. The leaves themselves acquire a gray-red color and look as if they are covered with road dust.
Flowers, shoots, fruits, juicy shoots can be affected by the pest. The larvae live and feed on the lower part of the leaves.
With a careful examination of fruit trees, it is not difficult to identify a tick infestation.
The colonization of ticks begins from the inner part of the crown of the tree, then they move higher along the trunk. A heavily affected plant may take on a pinkish or reddish tint. Damage and leaf fall can cause the tree to lose up to 40% of its chlorophyll.
Important points of tick development that gardeners need to consider
The female tick lays 2 to 4 eggs daily. The process of laying continues until late autumn, stops when the temperature drops to + 9 C. The pest overwinters at the stage of eggs laid in cracks in the bark, at the base of growths, in forks of branches, in knot grooves.
Females begin to lay eggs suitable for wintering from the second half of summer.
The larvae emerge from the eggs with the onset of warmth, in late April-early May, as soon as the buds begin to open. The appearance of adult females occurs at the end of May, after a few days they are able to reproduce offspring.
Unlike other pest species, the female red apple tick does not form cobwebs.
If the conditions are favorable, then no more than 7 days pass from the laying process to the formation of an adult who feeds on plant sap.
How to prevent spread
You can avoid massive destruction of the garden if you adhere to the rules of tree care:
- in the fall, all fallen leaves should be removed from the trunks;
- using a metal brush, it is necessary to remove the flaky remnants of the old bark;
- old and dry branches should be cut and burned.
Thus, the places of future wintering of new generations of the pest will be destroyed.
Trapping belts that collect a fairly large number of pests are effective. They need to be systematically treated with boiling water to destroy arachnids and insects.
Moisture and coolness prevent the red apple mite from multiplying. We cannot influence the weather. but watering the tree with high quality, at least several times per season, is within the power of most gardeners.
How to get rid of ticks using folk methods
If there are not very many pests detected, then you can try to do without the use of pesticides.
To destroy the tick, a strong tobacco infusion is used, prepared by infusing 1 kg of tobacco dust or chopped tobacco in 10 liters of water. The infusion is filtered, another 10 liters of water and 50 g of laundry soap are added to improve adhesion. It is advisable to repeat spraying the tree in a week.
For the treatment of trees, an infusion of chamomile is also used; 1 kg of dried grass is needed for a bucket of water. The infusion is prepared for 10 hours, filtered, then sprayed onto the trees. The procedure should be repeated after a week.
Chemical means of protection
A massive infestation with the red apple mite, especially if there is a threat to the crop, requires the use of insecticides.
Chemical treatment is carried out twice:
- immediately after the formation of ovaries;
- a month before the planned harvest.
In summer and spring, it is also practiced to spray trees with ether sulfonate (3 g of powder per 1 liter of water) or a solution of colloidal sulfur (10 g of powder per 1 liter of water) ten grams of sulfur per liter of water).
If mass reproduction of ticks is found in the garden, treatment with pyrethroid drugs against the codling moth is not carried out.
With the threat of pest infestation, treatments with specific acaricides are recommended:
In case of severe damage, insectoacaricides will give a good effect:
A chemical method of processing is also used, the trees are sprayed (washed):
- organophosphorus compounds,
- mineral oils.
Possible application against pests of biological pesticides based on avermectins.

The apple red mite is a serious threat to garden trees. For humans, it is completely safe, it does not feed on blood, contact with this arachnid can only cause an allergy.
