Alaska Tree Pest

Aphids are most active during the spring and early summer when temperatures are mild and new growth is emerging on trees and plants. They are attracted to trees with soft, succulent leaves and sap, which they feed on by piercing the plant tissue with their mouthparts.

Some of the trees that are most susceptible to aphid infestations include:

1. Fruit trees such as apple, peach, and cherry trees

2. Ornamental trees such as maple, birch, and magnolia trees

3. Evergreens such as spruce and fir trees

Aphids can cause damage to trees by sucking out the sap, which can weaken the tree and stunt its growth. They also produce a sticky substance called honeydew, which can attract other pests like ants and cause fungal growth on the tree.

To prevent or control aphid infestations, it's important to keep your trees healthy by watering them regularly, fertilizing them appropriately, and pruning them to remove any dead or diseased branches. You can also use natural predators like ladybugs or lacewings to control aphids, or apply insecticidal soaps or oils to kill them.
