The veterinary entomology project focuses on control of pest insects associated with food animal production, especially house flies and horn flies, and a manure management system utilizing the beneficial black soldier fly. This unique animal waste management system utilizes the non-pest native black soldier fly. It eliminates house fly production, and reduces manure accumulation by half. Also, prepupae are self-collected as they crawl off and are used as animal feedstuff. Sixty-six tons of prepupae could be collected each summer from just one commercial caged layer house. These are high in protein, energy and minerals. The feed value of the prepupal based feedstuff produced from Georgia's laying hens alone could amount to $7 million. Pollution abatement through waste reduction may be the greatest benefit.
Areas of this system under study are the biology and mass rearing of the black soldier fly, utilization of the prepupal feedstuff, food safety issues related to this feedstuff and the resulting manure residue, and nutrient depletion of the residue. Insecticide resistance management in house flies and horn flies is also an area of interest. New insecticides which show promise for inclusion in IPM programs are tested.
