Weaver ants as natural biocontrol agents against agricultural pests


Weaver ant workers hunt and kill insects that are potentially harmful plant pests, trees harboring weaver ants benefit from having decreased levels of herbivory. They have traditionally been used in biological control in Chinese and Southeast Asian citrus orchards from around least 400 AD. Many studies have shown the efficacy of using weaver ants as natural biocontrol agents against agricultural pests.Fruit trees harboring weaver ants produce higher quality fruits, show less leaf damage by herbivores, and require fewer applications of synthetic pesticides.
