"Harnessing natural insect power can, with proper management, have higher efficacy than resorting to harmful chemicals".

"Ants can be more effective than pesticides at helping farmers produce food, according to new research. They are better at killing pests, reducing plant damage and increasing crop yields, according to the first systematic review of ants’ contributions to crop production.

Ants are generalist predators and hunt pests that damage fruits, seeds and leaves, leading to a drop in crop yields. A greater diversity of ants generally provides more protection against a wider range of pests, the study found.

The analysis looked at 17 crops, including citrus, mango, apple and soya bean in countries including the US, Australia, the UK and Brazil. “In general, with proper management, ants can be useful pest controls and increase crop yield over time. Some ant species have similar or higher efficacy than pesticides, at lower costs,” researchers wrote in the paper published in Proceedings of Royal Society B."
