Old World monkeys

These primates cause damage to a vast array of crops. Primary targets include maize, sorghum, millet, bananas, citrus fruits, and oil palm plantations. Because they operate in groups, their ability to consume or destroy large quantities of produce in a short timeframe makes them a severe economic threat to local and commercial agriculture.

The biology of Cercopithecidae is characterized by complex social hierarchies and group living. They exhibit advanced learning behaviors, allowing them to adapt to new environments and overcome basic agricultural defenses. Their reproduction rate, while lower than that of insects, is offset by high juvenile survival rates in areas near human settlements.

The damage caused is often indiscriminate. Beyond direct consumption, these animals cause severe physical destruction to crop structures, such as breaking maize stalks or snapping fruit-bearing branches. This activity leaves crops vulnerable to secondary rot and pest infections, reducing the overall market value of the harvested yield.

Effective mitigation strategies are essential for crop preservation:

• Installation of physical barriers such as chain-link fencing or electric fencing.
• Deployment of bio-acoustic deterrents that mimic predator calls.
• Strategic crop planning to include non-palatable buffer zones.
• Active surveillance and the use of guard animals to deter group incursions.
