Dragonfruit plants are ornamental and edible cacti that require specific care to thrive. The plant is vulnerable to pests like the Lerp insect, which can cause significant damage to the plant if not controlled. The Lerp insect is a small, flat, white or gray insect that feeds on the sap of the plant. As they feed, they leave behind a sticky secretion called honeydew, which attracts other pests like ants and mold. If you have noticed these pests on your dragonfruit plant, here’s a guide on how to get rid of them.

Identify the Lerp Insect

The Lerp insect is easy to identify on the dragonfruit plant. They appear as small, flat, white or gray insects that stick onto the leaves and stems of the plant. Once they invade the plant, they create a waxy layer over their bodies that protects them from predators and pesticides. The waxy layer also makes it difficult for pesticides to penetrate through and eliminate them.

Manual Removal

The best and most effective way to remove Lerp insects from your dragonfruit plant is through manual removal. You can do this by using a soft-bristled brush or cloth to gently scrub the leaves and stems of the plant to remove the insects. Be careful not to damage the plant while doing so.

Use Insecticides

If manual removal doesn’t work or if there are too many pests on the plant, you can use insecticides. However, since Lerp insects are protected by their waxy layer, you need to use specific insecticides that can penetrate through and kill them. Look for insecticides that contain neonicotinoids or systemic insecticides like Imidacloprid.

Prune Infected Parts

If your dragonfruit plant is severely infected with Lerp insects, you may have to prune the infected parts. This will prevent the pests from spreading to other parts of the plant. Use clean and sterilized pruning shears to cut off the infected parts and dispose of them properly.

Keep the Plant Healthy

A healthy plant is less vulnerable to pests and diseases. Ensure that your dragonfruit plant receives proper care, including regular watering, fertilization, and adequate sunlight. A healthy plant can also recover quickly from pest infestations.
