Mayhaw Insect Problems: How to Spot, Prevent and Control Them

Mayhaw trees are popular fruit-bearing plants in the southern United States. They produce small, tart berries that can be used to make jams, jellies, and other delicious treats. However, like any plant, mayhaws are susceptible to insect problems that can damage or even kill the tree. In this article, we will discuss some of the most common insect problems that mayhaw trees face, how to spot them, and what you can do to prevent and control them.

1. Mayhaw Bud Weevils

Mayhaw bud weevils are a type of beetle that feeds on the buds of the mayhaw tree. The adult weevils emerge from the ground in early spring and feed on the buds as they begin to open. This can cause significant damage to the tree, as it reduces the number of flowers and fruit that will develop that year.

You can spot mayhaw bud weevil damage by looking for small holes in the buds or discoloration around the edges. If left untreated, the infestation can spread and cause significant damage to the tree. To prevent mayhaw bud weevils, you can apply an insecticide in late winter or early spring before the buds begin to open. You should also remove any fallen leaves or debris around the base of the tree, as these can provide a habitat for the weevils.

Mayhaw bud weevils can cause severe damage to the tree if left untreated.

2. Scale Insects

Scale insects are small, sap-sucking insects that attach themselves to the branches and leaves of mayhaw trees. They appear as small bumps or lumps and can be difficult to spot without close inspection. Scale insects can cause stunted growth, yellowing or browning of leaves, and can weaken the tree over time.

To prevent scale insects, you can spray the tree with horticultural oil during the dormant season. This will smother the eggs and larvae of the insects and prevent them from reproducing. You can also use a soft brush to remove adult scales from the branches and leaves of the tree. If the infestation is severe, you may need to apply an insecticide.

Scale insects can weaken the tree over time if not treated properly.

3. Aphids

Aphids are another type of sap-sucking insect that can cause damage to mayhaw trees. They are small, pear-shaped insects that cluster together on the leaves and stems of the tree. Aphids can cause distortion and curling of leaves, as well as stunted growth and reduced fruit production.

To prevent aphids on your mayhaw tree, you can introduce natural predators such as ladybugs or lacewings to the area. You can also spray the tree with a soapy water solution, which will suffocate the aphids. If the infestation is severe, you may need to apply an insecticide.

Aphids can cause leaf distortion and reduced fruit production.

4. Spider Mites

Spider mites are tiny arachnids that feed on the sap of the mayhaw tree. They are typically found on the underside of leaves and can cause a stippling or mottling effect on the foliage. Severe infestations can cause the leaves to become discolored and fall off the tree.

To prevent spider mites on your mayhaw tree, you can spray the tree with a strong jet of water to knock them off the leaves. You can also use a miticide to treat the infestation. Be sure to follow the instructions carefully, as some miticides can harm beneficial insects as well.

Spider mites can cause discoloration and leaf drop if left untreated.

5. Japanese Beetles

Japanese beetles are a common pest that can cause significant damage to mayhaw trees. They feed on the leaves, flowers, and fruit of the tree, causing skeletonization and defoliation. Japanese beetles are more active in warm weather and can quickly decimate a tree if left unchecked.

To prevent Japanese beetles on your mayhaw tree, you can use a pheromone trap to attract and catch the adult beetles. You can also apply an insecticide to the tree, but be sure to follow the instructions carefully and avoid using during periods of high bee activity. Removing fallen fruit and pruning damaged branches can also help reduce the risk of Japanese beetle infestations.

Japanese beetles can quickly decimate a mayhaw tree if left unchecked.

Mayhaw insect problems can be frustrating for gardeners and orchard owners, but with proper prevention and treatment, they can be managed effectively. By monitoring your tree regularly and taking action at the first sign of an infestation, you can keep your mayhaw tree healthy and productive for years to come.
