Environmental conditions influencing growth and development of the black soldier fly (Hermetia illucens (L.)) (Diptera: Stratiomyidae)

Abstract

While biotic conditions are recognised contributors to the growth and production of the black soldier fly, Hermetia illucens (L.) (Diptera: Stratiomyidae), abiotic conditions are arguably of equal or greater relevance. Shifts in key environmental conditions can be the difference between optimal production of a black soldier colony, or its collapse. As with all insects, the impact of these criteria is highly dependent on development stage of the insect and scale of application (e.g. growth chamber in a laboratory versus an industrial rearing room). Through the analysis presented herein, the impact of three abiotic factors (temperature, humidity, and photophase) on immature black soldier flies will be discussed as a means to serve as a model for investigating other abiotic factors contributing to the physiology of the species. By identifying the impact of these factors on black soldier fly development, the industry can optimise production, minimise financial investment, and enhance the economic and environmental returns of the system.
