BSFL 101 - Life Cycle
7
BSFL as Biological tools
• Waste Management o Nitrogen reductions up to 25%
o Overall mass reductions of 56%
• Animal feed o Swine, chickens, catfish
o Nutritional content
8
BSFL as Biological Tools cont.
• Pest Control
• House flies and blow flies o Oviposition prevention
o Larval competition
9
Project Planning: PMEI Visit
• Met with the clients at PMEI
• Set project goals: o Meet the protein supplement need of 45 chickens
o Off-season production?
10
BSFL Experiment
• Goal: Determine conditions and resources
necessary to breed Black Soldier Flies
indoors
• ~100 BSFL ordered online,
feeding begins o High mortality
11
Redesign
• Reevaluation: focus on feeding first,
breeding later
• Experimental Design o Vary food sources
o Maintaining constant temperature and humidity
12
Experimental Results
• Observations o Food scrap/coffee: largest
o Coffee: most active
o Food scraps: burrowed under tape
• Greenhouse temp highly variable: 57-108 oF
• Humidity maintained close to optimal (50%)

Structure Design: "Grub Tub"
Basics:
• Structure & Design
• Scale

Structure Design: "Grub Tub"
Final Design:
• Small dish tub (1x1.5 ft) with tubing
extended
• Shed near chickens to protect from weather
18
Deliverables
• How-To-Guide for BSFL
production in the
Piedmont bio-region
• Poster to be presented
at the Association for
Environmental Studies
and Sciences 2013
conference
• Grub Tub
• Final report with
complete account of
research
19
Final Recommendations
• Off-season BSFL operation
• Advocacy for implementation
• Closed system vs. Natural breeding
