Horses need help when it comes to insect pests like flies but many horse owners are in the dark about how best to effectively manage it.
A new overview of equine fly management in the latest issue of the Journal of Integrated Pest Management, an open-access journal that is written for farmers, ranchers, and extension professionals.
One fly-management method that is gaining ground is the use of wasps that are parasitoids of fly pupae. The female wasp inserts an eggs into the fly puparium, and when the egg hatches, the wasp larva eats the fly pupa.
The authors conducted research on two wasp species that are sold commercially to see what type of manure they preferred.
