White-eyes (Zosteropidae)
The family Zosteropidae, commonly known as white-eyes, belongs to the order Passeriformes. These small birds are easily identified by the distinct white ring around their eyes. While they are known to provide some biological control by eating insects, they can become significant agricultural pests in areas where their population density is high and commercial fruit production is concentrated.

White-eyes (Zosteropidae)
White-eyes are notorious for damaging various horticultural crops, particularly grapes, figs, peaches, and citrus fruits. As opportunistic feeders, they consume the pulp of ripening fruits, often causing extensive destruction. Their preference for sugar-rich fruits makes them a recurring challenge for vineyard and orchard managers during harvest season.
The biology of these birds is marked by highly gregarious behavior. They forage in large flocks, which significantly increases the rate of crop consumption per unit of time. Their reproductive cycle and habitat preferences allow them to thrive in human-modified landscapes, ensuring a consistent presence in agricultural zones where food resources are abundant.
The damage caused by white-eyes is characterized by puncture wounds and deep gouges in the fruit surface. This destruction leads to rapid spoilage and secondary infections from fungi and bacteria. Consequently, even minor feeding damage can render entire clusters or fruit batches unmarketable, resulting in substantial financial losses for farmers.
To mitigate the negative impact of Zosteropidae, integrated pest management strategies are essential. Growers often utilize netting as the most effective physical barrier for valuable crops. Additionally, deterrent methods such as acoustic scaring devices, reflective visual markers, and habitat modification are used to reduce flock pressure during the most vulnerable stages of fruit ripening.
