Pests Strike as Mangoes Begin to Ripen

In a blow to mango lovers and farmers alike, a severe pest outbreak has hit mango orchards across Uttar Pradesh, particularly in Malihabad. As mangoes grow in size, rising temperatures have triggered a surge in pest activity, leaving fruits scarred, deformed, and less marketable. Although this season has produced larger fruits compared to previous years, pests like the dudwa (paired fruit borer) and the cutter (semilooper or humpback caterpillar) are causing significant damage. These pests target tender-skinned fruits and clusters, reducing both quality and yield.

Insects Thrive in Heat, Say Experts

Dr. T. Damodaran, Director of the Central Institute for Subtropical Horticulture (CISH), confirmed that rising temperatures are helping pests multiply rapidly. “While mango leaves have hardened, insects are now laying eggs on the developing fruits and their stalks,” he explained. Bagging fruits remains the most effective defence. However, with each bag costing around ₹20, many small farmers cannot afford this method. For them, scientists recommend targeted insecticide sprays—focused only on areas where pests are active—to avoid waste and ensure better results.

Sneaky Invaders Need Smart Control

The semilooper, for instance, drops from trees using a silk thread when disturbed by wind, rain, or pesticides, often crawling back afterwards. To prevent this, experts advise spraying tree trunks in addition to the canopy. The paired fruit borer lays eggs between two mangoes or inside clusters, making it harder to detect. If not controlled early, both pests can cause widespread damage.

Timely Action Can Save the Season

Farmers can take preventive steps such as:

• Bagging fruits early

• Using light, frequent irrigation

• Mulching the tree base with dried leaves

• Managing tree canopies to keep height low and access easier

These simple steps can reduce pest pressure and protect crop quality, even in high temperatures.
