Most Common Citrus Plant Pests:
Identification and Treatment Guide

Citrus plants are popular among gardeners and homeowners for their bright, juicy fruits and fragrant blooms. However, these plants are susceptible to various pests that can damage fruit, leaves, and stems, and even kill the plant if left untreated. In this article, we will provide a guide to help you identify the most common citrus plant pests and offer effective treatment options.

1. Aphids

Aphids are small, soft-bodied insects that suck sap from the leaves and stems of citrus plants. They are usually green or yellow in color but can also be black or brown. Signs of aphid infestation include curled or distorted leaves, yellowing or stunted growth, and the presence of sticky honeydew on the leaves.

Treatment

Aphids can be controlled by spraying the plant with insecticidal soap or neem oil. You can also introduce natural predators like ladybugs or lacewings to your garden to control aphid populations.

2. Citrus Leaf Miner

Citrus leaf miner is a tiny moth whose larvae tunnel through the leaves of citrus plants, causing them to curl and distort. The damage caused by citrus leaf miner can weaken the plant and make it more susceptible to other pests and diseases.

Treatment

Preventative measures like pruning affected leaves and reducing nitrogen fertilizer can help control citrus leaf miner. Insecticides like spinosad or carbaryl can also be applied to control the pest.

3. Citrus Red Mite

Citrus red mites are tiny arachnids that feed on the sap of citrus plants, causing yellowing or bronzing of leaves. The damage caused by citrus red mites can also lead to defoliation, reduced fruit yield, and even death of the plant if left untreated.

Treatment

Citrus red mites can be controlled by spraying the plant with miticides like abamectin or fenbutatin oxide. You can also introduce natural predators like predatory mites or ladybugs to control populations.

4. Citrus Rust Mite

Citrus rust mites are also tiny arachnids that cause damage to citrus plants. They feed on the underside of leaves, causing silvering or bronzing of the upper surface. Severe infestations can lead to defoliation and reduced fruit yield.

Treatment

Citrus rust mites can be controlled by spraying the plant with miticides like lime sulfur or wettable sulfur. Introducing natural predators like predatory mites can also control citrus rust mite populations.

5. Scale Insects

Scale insects look like small, flat, oval bumps on the stems and leaves of citrus plants. They feed on the sap of the plant, causing yellowing or wilting of leaves, stunted growth, and reduced fruit yield.

Treatment

Scale insects can be controlled by spraying the plant with horticultural oil or insecticidal soap. You can also introduce natural predators like parasitic wasps or ladybugs to control scale insect populations.
