How could climate change influence the distribution of the black soldier fly, Hermetia illucens (Linnaeus) (Diptera, Stratiomyidae)?

Abstract

The black soldier fly, Hermetia illucens (Linnaeus, 1758), is a saprophagous species used to decompose organic matter. This study proposes a distribution model of H. illucens to illustrate its current and future distribution. The methodology includes data collection from the Global Biodiversity Information Facility (GBIF), complemented with iNaturalist, manual expert curation of occurrence records, six species distribution models algorithms and one ensemble model. The average temperature of the driest annual quarter and the precipitation of the coldest annual quarter were the key variables influencing the potential distribution of H. illucens. The distribution range is estimated to decrease progressively and their suitable habitats could change dramatically in the future due to global warming. On the other hand, current optimal habitats would become uninhabitable for the species, mainly at low latitudes. Under this scenario, the species is projected to move to higher latitudes and elevations in the future. The results of this study provide data on the distribution of H. illucens, facilitating its location, management and sustainable use in current and future scenarios.

Flight toward Sustainability in Poultry Nutrition with Black Soldier Fly Larvae

“…Thriving best in temperatures of 25 • C to 30 • C, BSFL can also grow in a range of environmental conditions, showcasing their resilience. Their natural inclination toward habitats rich in decomposing organic material, coupled with this adaptability, highlights their pivotal role in sustainable agriculture and waste management, suitable for diverse geographical locations [8][9][10]. These larvae, which can grow up to 27 mm in length and weigh approximately 220 mg, are nutritionally dense, with a composition rich in proteins and fats [11][12][13][14][15][16][17].…”
