Mango spring to prevent locusts

The mango worm, both in its adult and nymph stages, primarily feeds on the shoots and the upper surfaces of young leaves. These pests feed on the sap found in flower spikes and young fruit stalks, which leads to symptoms such as leaf curling, shoot tip dieback, and premature dropping of flowers and fruits. This feeding activity significantly hinders the growth of new shoots. In severe infestations, it can result in the death of entire shoots. To manage this pest, several control methods are recommended. First, biological control is an effective and environmentally friendly approach. Natural predators such as ladybugs, lacewings, spiders, and certain types of parasitic wasps can help keep mango worm populations in check. When using chemical pesticides, it's important to choose selective products that minimize harm to beneficial insects. This helps maintain a balanced ecosystem within the orchard. In addition to biological control, chemical control measures can be applied when necessary. For large infestations, foliar sprays such as 50% imidacloprid WP, 40% dimethoate EC diluted at 1000–1500 times, or 2.5% lambda-cyhalothrin (commonly known as Kung Fu) at 3000 times dilution can be used. Applications should be spaced 7–10 days apart, with 2–3 treatments typically required for effective control. It’s also important to rotate pesticide types to prevent resistance development and ensure long-term effectiveness. By combining these strategies, farmers can effectively manage mango worm infestations while maintaining the health and productivity of their mango trees.
