Oriental white-eye

The Oriental white-eye (Zosterops palpebrosus) belongs to the Zosteropidae family within the order Passeriformes. While often appreciated for its role in pollination, this species is frequently categorized as a significant pest in agricultural sectors across South and Southeast Asia, where it targets ripening fruit crops.

Their diet is diverse, including nectar, insects, and fruits. They represent a substantial threat to commercial vineyards, orchards growing peaches, plums, and various berry farms. Due to their gregarious nature and habit of feeding in large flocks, they can quickly deplete fruit stocks in an unprotected orchard.

The biology of the Oriental white-eye is closely aligned with the seasonal availability of fruit. They are highly agile birds with strong foraging instincts. Their reproductive cycles and movement patterns are often synced with the maturation of local crop harvests, leading to peak pressure on farmers during the critical harvest window.

Damage is characterized by precise pecking at the fruit skin, which exposes the underlying flesh. This activity leads to immediate loss of aesthetic quality and weight, while the open wounds serve as entry points for pathogens, fungi, and fruit flies, significantly accelerating the decomposition process of the affected crops.

To mitigate the impact of the Oriental white-eye, farmers employ several management techniques:

• Exclusion netting to physically prevent birds from reaching fruits.
• Acoustic deterrents such as distress call broadcasts.
• Visual repellents like holographic streamers or reflective tape.
• Strategic timing of harvesting to remove ripening fruit from reach as quickly as possible.
