How to Control Avocado Pests
Avocado Pests: Identifying the Most Common Pests and Their Impact on Your Crop
- Avocado Lace Bug: These tiny insects feed on the undersides of avocado leaves, causing stippling and discoloration. They can weaken the tree if left untreated.
- Avocado Leafroller (Amorbia cuneana): Leafrollers roll avocado leaves to create protective shelters while feeding. They can cause leaf damage and potentially affect the fruit.
- Avocado Whitefly (Trialeurodes floridensis): Whiteflies feed on the sap of avocado leaves, leading to yellowing, wilting, and a sticky residue known as honeydew. They can transmit diseases to avocado trees.
- Redbay Ambrosia Beetle (Xyleborus glabratus): These beetles bore into avocado trees, introducing a fungus (Raffaelea lauricola) that causes laurel wilt disease, which can rapidly kill the tree.
- Fruit Borers: Various caterpillars, such as the avocado fruit borer (Stenoma catenifer), can infest avocado fruit, making it unmarketable.
- Mites: Spider mites and other mites can damage avocado leaves by piercing cells and sucking out their contents. This can lead to bronzing and leaf drop.
- Mealybugs: Mealybugs feed on avocado leaves and fruit, often secreting a waxy substance that can harbor sooty mold, further impacting tree health.
