Insect pests often feed on the branches and stems of plants, creating holes or tunnels that can severely damage the growth of trunks and main shoots. This kind of infestation not only weakens the plant's structure but can also lead to disease infections or even plant death if left untreated.
To manage these pests effectively, several control methods can be applied:
1. Manually remove larvae by cutting off affected parts of the plant and destroying the larvae. This is especially effective when the infestation is still in its early stages.
2. For adult insects, manual collection or using black light traps can help reduce their population. This method is environmentally friendly and suitable for small-scale infestations.
3. Apply chemical treatments such as 80% dichlorvos diluted at a ratio of 500 times or 40% omethoate diluted between 20 to 50 times. These solutions can be injected directly into the holes created by the pests or used to soak cotton swabs, which are then inserted into the damaged areas. After treatment, it's important to seal the holes with a layer of mud or sealing compound to prevent re-infestation and promote healing.
Regular monitoring and timely intervention are crucial for long-term pest management. Combining both physical and chemical methods usually yields the best results while minimizing harm to beneficial insects and the environment.
