Fruit from the local garden is the pride of every gardener. But as popular as apple, pear or cherry are with us humans, it is the fruit trees even with pests. Now it would be nonsensical to want to protect the fruit trees in advance against pests. But every tree has its peculiarities, which could not be covered with a single measure. Moreover, it is natural that fruit trees protect themselves in some way. This happens, for example, by the falling of the leaves and their rotting. The result is natural humus, which provides the tree with the necessary nutrients.

Despite self-protection, it is often unavoidable that pests settle on and on fruit trees. A large part of the pests are caterpillars, mites and aphids. But you should distinguish between real pests and less dangerous animals before you start fighting them.

Small and large frost breaker

One of the most dangerous caterpillars is the frost tensioner . Whereby one differentiates exactly between the small and the big frost-tensioner. Most dangerous for fruit trees is the small frost spanner. If a fruit tree, or other woody plants, are attacked by the small frost vein, it can come in the worst case to Kahlfraß.

To control the pest infestation, you can hang nesting boxes for great tits. For the birds, the frost tensioning caterpillars are a favorite dish. If it does not work naturally to combat the frost-breaker, wrap glue rings around the trunk. Once the sticky effect subsides, the glue rings must be changed.

Leaf bug

Although the leaf bug does not harm humans or animals, it is harmful to our fruit trees. Leaf bugs are between five and ten millimeters in size, have wings and a yellow-green-red color mixture. They feed on the sap and thus ruin the tree. Visible is the infestation of tattered leaves and malformed fruits.

Leaf bugs are very heat loving, that is, it gets colder and wetter, they disappear again by itself. If that is not enough for you, it is probably only a fight with paraffin oil-containing remedies.

The fruit moth is a pest that affects not only apple trees or apples. Also pear and quince as well as stone fruit, figs and walnuts are colonized by the pest. The females lay eggs, from which the caterpillars hatch. The gluttonous animals then unobtrusively make use of the shell of the apple right down to the pulp.

To give the codler no chance, wrap a wide strip of corrugated cardboard around the tree trunk. The space in the corrugated board is used by the fruit mats as lodging for laying eggs. At the end of July you can remove the cardboard again and dispose of it together with codling moth.

Other pests

On fruit trees, however, there are far more pests than those mentioned here. Animals such as the leaf flea, the gallmidge, the hazelnut drill and the raspberry beetle also cause damage.
