Chrysomya Bezziana - Management and Control

Management and Control

Management of Chrysomya bezziana can be conducted using several different methods, depending upon the adult or larvae form.

To remove and manage the infestation of larvae in the host, the larvae may be removed with forceps. This removal process should take place daily or as often as needed until the infestation is clear. These larvae can also be killed by applying proper insecticides to the infected areas and making sure the wounds are properly dressed. Organophosphorus insecticides like coumaphos, dichlofenthion, and fenchlorphos can be applied to wounds with fly larvae. These cause the larvae to leave the wound and fall to the ground, and the larvae will die without a host to feed on. Castration wounds in cattle that have insect growth regulators, such as dicyclanil, have high success rates of preventing the establishment of C. bezziana.

When trying to manage areas that have adult Chrysomya bezziana, one of the first tasks is to improve sanitation of the area. Many types of decaying matter serve as a food source and should be cleared out of the area. Adult flies can also be controlled by the use of insecticides. A few of the insecticides that are available for use in the management of adult C. bezziana include: ectopor, diazinon, nagasunt and coumaphos. When trying to prevent infestation of livestock and other animals, proper spraying and dipping with these insecticides can help in management control.
