Some Common Pests that Affect Pear Trees


It’s not only humans who find pears succulent and delectable. Some pests do, too. When they attack and feast on pears, you might find your fruits too damaged to be consumed by humans. So better take the necessary precautions.

Here are some of the most common pests that can affect pear trees:

Codling Moth

This insect is one of the most deadly pests that can attack pear trees, apples and crab apples. If you are not familiar with this insect, they are the same worms (their larval stage) you see in “wormy apples.”

They lay eggs on the leaves and feeds on it as larvae. Later on, they start feeding on the developing fruit. When they become fully-grown, they crawl out from inside the fruit and crawl to the tree’s trunk where they will pupate under the protection of bark flaps.

Pear Slug or Sawfly

Pear sawfly feed on upper surface of the leaves of pears and several other plants. They look similar to slugs but they are actually a type of non-stinging wasp.

These pests usually create havoc in the area between the main vein on the upper leaf, eating away the softer parts of the leaves and leaving the veins.

Pear Psylla

It’s another serious pear pest that must be controlled. Pear Psylla are aphid-like insects that suck the sap from the leaves which can eventually weaken your pear tree.

You will notice if your tree is infested with this insect when you see sticky drops of honeydew coating your tree and its fruits.

Scale Insects

These tiny and round insects are most commonly found on branches and fruits, typically that of pears and apples.

Although they develop slowly, they are deadly in a sense that they can cause the death of the particular branch where they are. This can contribute to the overall decline of your pear tree.
