Genetic differentiation in domesticated black soldier fly (Hermetia illucens) populations.

ABSTRACT:

Background

The black soldier fly (BSF, Hermetia illucens) is widely used for waste bioconversion and sustainable protein production. However, domestication and prolonged captive rearing can rapidly alter genetic diversity and population structure. This study investigated how selective breeding, genetic drift, and relaxed selection have shaped genomic variation and effective population size in multiple BSF populations. Using genome-wide restriction site-associated DNA sequencing, we analysed population structure, heterozygosity, and selection signatures across 11 BSF populations, including 1 long-term domesticated line, 5 selectively bred lines (Line A to Line E), 3 wild-derived populations, and 2 commercial strains.

Results

Despite shared origins, lines LA to LE diverged rap
