Black Soldier Fly e-Books

by Terry Green on 11/16/12

At DipTerra ( we have compiled a series of practical “how to” eBooks in pdf format available for purchase which provide detailed information on the propagation, management and maintenance of a Black Soldier fly nursery, how to build a food scrap recycling bin in processing food scrap waste, information on the biology of the Black Soldier fly, and related recycling applications. These eBooks are based on scientific and practical knowledge gained through in depth observations on the characteristics and behavior of Black Soldier flies and studies relating to the decomposition of biodegradable waste materials. If you want to set up a Black Soldier fly nursery designed to propagate Black Soldier flies, for example, you may want to read our DipTerra e-Book titled "Propagating Black Soldier Fly Larvae in Nurseries" (Fig. 1).

Black Soldier flies, unlike the common house fly, do not  spread diseases. They avoid houses, preferring instead to habitat outdoors. Adults do not feed on waste, and live for no more than four or five days at most after emerging from their chrysalis, just long enough to find a mate. After mating, females lay upwards of 400 or more eggs in clutches near decaying organic waste.

Larvae spawned from the eggs rapidly consume the waste, mineralizing it as they grow, and advance into a prepupa stage at which point they crawl (self-harvest) free of the waste and off to a hiding place under rocks or other quiet spaces. There they undergo metamorphosis, emerging free of their chrysalis some three weeks or so after entering the pupa stage (under optimal growth conditions conducive to metamorphosis) as adults ready to repeat the cycle over again.

The advantage of using Black Soldier flies in processing food scrap is that they are extremely efficient in breaking down the waste. They are indigenous  throughout the tropic, subtropic  and temperate zones of the world to about the 49th Parallel North and South of the equator. They are not regarded as pests. Adults stay out of sight by hiding in bushes and trees. During the larval stage they confine themselves in feeding and growing on waste, assimilating the nutrient value stored up in the waste into insect biomass.

Larvae have proven value as poultry and fish meal. Their exoskeleton is comprised of high quality chitin of known medical value as a starting product in the production of chitosan. Processed leachate derived from the liquid released in decaying organic wastes on which larvae feed furthermore has beneficial effects on the growth of plants (see Black Soldier Fly Processed Food Scrap | Foliant and Soil Applications).
