It mainly harms the leaves. The nymphs and female adults suck sap from the back of the leaves, causing yellow-green spots to appear on the front of the leaves. In severe cases, it will affect the growth and development of the entire plant.

Prevention and treatment methods

Usually, you should pay more attention to the rationality of fertilization and watering, and provide more light and ventilation. If you find branches and leaves that have been infested by insects, you should cut them off and burn them immediately. In addition, spray 1000 times diluted 90% dichlorodiphenyltrichloroethane evenly for prevention and control.

The pest mainly comes out in large numbers in the evening or early morning after a heavy rain to eat the flowers and tender leaves of Strelitzia reginae, causing serious damage to its appearance.

Prevention and treatment methods

Dead branches and leaves should be removed promptly. Once pests and diseases are discovered, they should be killed manually, or poison baits such as snail killer should be spread in places where they frequently move to lure and kill them. In addition, spray 50% octyl sulphate and 80% dichlorvos for drug control.
