Bee-eaters
The Meropidae family, commonly known as bee-eaters, belongs to the order Coraciiformes. These birds are specialized aerial insectivores that primarily prey on flying insects, including honeybees, wasps, and bumblebees. In the context of agriculture, they are considered pests due to their significant impact on apiculture and the pollination of entomophilous crops.

Bee-eaters
Crops that suffer from the activity of bee-eaters are those that rely heavily on honeybees for pollination. When large colonies of bee-eaters establish themselves near apiaries, they consume a high volume of foraging bees daily. This loss reduces the overall strength of the hives, limits nectar collection, and impairs the necessary pollination of commercial crops.
The biology of Meropidae involves colonial nesting, typically in burrows excavated in sandy banks or steep cliffs. Their life cycle is synchronized with the period of peak insect flight activity. During the breeding season, the birds' energetic needs are high, leading to concentrated hunting pressure on nearby honeybee populations, which often coincides with the flowering stages of various agricultural plants.
The damage caused by bee-eaters is primarily through the predation of foraging bees, which disrupts the normal rhythm of the colony. The presence of these birds often causes bees to stay inside the hive to avoid predation, thereby reducing the rate of flower visits. This leads to poor pollination success and decreased yields in agricultural production areas.
Effective management and protection strategies for beekeepers include:
- Using reflective tapes and mirrors to disorient and deter the birds.
- Deploying acoustic deterrents that emit sounds of predators or distress calls.
- Moving apiaries to locations further away from known nesting sites in rivers or quarries.
- Installing protective mesh covers over hives during peak migration or nesting times to allow safe movement for bees.
