Research Project:
Rearing and Release Technology for Biological Control & Sterile Insect Releases of Fruit Flies
Location:
Tropical Plant Pests Research
Project Number: 5320-22430-019-00
Project Type:
Appropriated
Start Date: Oct 24, 2001
End Date: Aug 31, 2005
Objective:
Develop efficient rearing technology to produce high quality Mediterranean, oriental, melon, and Malaysian fruit flies and their associated parasitoids. Improve quality and quality control procedure and reduce negative effects of sterilization, shipping, distribution, and dye marking on sterile fly releases. Reduce operating costs including waste disposal costs of mass rearing operations.
Approach:
Modification in diet components, antibiotics, pH, and temperature regimens will be evaluated by yield and quality of produced flies. Use of various devices to stimulate mating, attack rate, and survival will be evaluated in mass rearing parasitoids. Strains of flies will be evaluated for ease and yield of mass rearing, quality, and field effectiveness. Comparisons of several medfly genetic strains and "males only" releases will be conducted in field releases in coffee plantations. Recycling of used larval media & the utilization of spent media for animal feed will be evaluated. Optimal pH, heat regimens, optimum diet for animal feed will be factors causing colony mortality and/or lowering of fecundity will be determined. Behavioral and fitness parameters of parasitoids will be quantified and incorporated in rearing, packaging, shipping, and release procedures. (Replacing 5320-22430-018-00D, 9/28/01)
