How to Deal with Pests that Affect Pears

fruit-pest

There are several insects that feast on the pear’s succulent fruits, leaves and even branches.  They create damage to your tree by eating its leaves and sucking nutrients from the tree that’s why it’s important to know how to deal with them.

What are these pests and how do you make them go away?

Codling Moth

These insects are the same worms you see in “wormy apples.”  Yes, they are insects all right.  They are only worm-like during their larval stage.

Coddling moth lay their eggs on the leaves of pear trees and feeds on it, too.  Once they have become adults they move to eat the fruits and much later, move out from the fruit to pupate in the tree’s bark flaps.

Insecticides can be used to control this pest, but it must be applied immediately after petal fall and never during periods of bloom.  Doing this would kill pollinators.

A few pesticides you can use are Permethrin and Carbaryl (Sevin).

Pear Slug or Sawfly

Pear sawflies are a lot similar to slugs in appearance but technically, they are a type of non-stinging wasp.

These east the leaves of pears leaving out the veins which makes the remains of the leaves look like a skeleton.

Pear slugs can easily be controlled.  Just use home orchard insecticide and insecticidal soaps.  The larvae of pear slugs can also be washed away if use a vigorous jet of water on it.  Dusting the leaves lightly with wood ashes will also work.

Pear Psylla

Another serious pear pest that has to be constrained is Pear Psylla.  This pest looks a lot like aphids.  They suck out the sap from the leaves and can lead to the weakening of your tree.

Unfortunately, this pest is highly resistant to most insecticides.  But you can use oil sprays or sulfur-based sprays, although you should not mix the two or you might injure you tree.  Remember to use sprays during the pear tree’s dormant season.

Scale Insects

Typically found on branches and fruits of pear and apple trees, this tiny insect can kill the particular branch where they are crowding.  Heavy infestation can eventually lead to the overall deterioration of your pear tree.

Scale infestations are slow to develop and treatments are seldom needed in backyard orchards.  In case you are experiencing an infestation of scale insects in your own tree, you can use horticultural oils during the tree’s dormant periods.
