bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 10, 2024

Abstract In animal breeding programs, utilizing quantitative genetic designs such as the full-/half-sibling design is fundamental. A demands that mating can be controlled, and individuals tracked for construction of a pedigree. nature, black soldier fly ( Hermetia illucens L.) males are reported to gather in lekking groups engage competitive displays courtship rituals before mating. This behavior described crucial establishing suitable conditions achieving successful mating, polygyny therefore assumed rare. We show when exposing virgin male female, they readily mate, demonstrating ability mate without prior it possible selected pairs. Furthermore, we achieved between an individual at least four females within four-hour time span, nearly all matings result live offspring. Our findings pave way moving H. programs beyond mass selection towards advanced selective demanding controlled Such enable multiple traits simultaneously, used prevent inbreeding, drastically increase rates responses compared selection.

Rapid Evolutionary Adaptation to Diet Composition in the Black Soldier Fly (Hermetia illucens)

Insects, Journal Year: 2023, Volume and Issue: 14(10), P. 821 - 821

Published: Oct. 18, 2023

Genetic adaptation of Hermetia illucens (BSF) to suboptimal single sourced waste streams can open new perspectives for insect production. Here, four BSF lines were maintained on a sourced, low-quality wheat bran diet (WB) or high-quality chicken feed (CF) 13 generations. We continuously evaluated presumed evolutionary responses in several performance traits rearing the two diets. Subsequently, we tested interchanged diets, i.e., larvae that had been reared and vice versa evaluate costs associated with different found experience rapid composition. While performances WB always inferior CF diet, adaptive stronger former diet. This response was likely due selection pressure experienced by fed The experiment no adaptation, but revealed cross generational gain parental treatment. Our results rapidly respond adaptively although mechanisms are yet be determined. has potential utilized commercial breeding produce tailored specific

Whole-genome sequencing of two captive black soldier fly populations: Implications for commercial production

Genomics, Journal Year: 2024, Volume and Issue: 116(5), P. 110891 - 110891

Published: June 22, 2024

Black soldier fly (BSF; Hermetia illucens) is a promising insect species for food and feed production as its larvae can convert different organic waste to high-value protein. Selective breeding one way optimize production, but the potential of only starting be explored not yet utilized BSF. To assist in monitoring captive population implementing program, genomics tools are imperative. We conducted whole genome sequencing two populations separated by geographical distance - Denmark (DK) Texas, USA (TX). Various genetics analyses revealed moderate genetic differentiation between populations. Moreover, we observed higher inbreeding DK population, detection subpopulation within aligned well with recent foundation from Additionally, generated gene ontology annotation variants wider applications. Our findings establish robust marker set research genetics, facilitating laying groundwork practical programs

What Veterinarians Need to Know About the Newly-Emerging Field of Insects-as-Food-and-Feed

Veterinary Sciences, Journal Year: 2024, Volume and Issue: 12(1), P. 12 - 12

Published: Dec. 31, 2024

Over the last two decades, insects-as-food-and-feed industry has rapidly emerged. Its growth is largely because insects require substantially less resources (water, food, and energy) to produce than traditional sources of animal protein, making it a sustainable alternative food option. As this continues grow, veterinarians will likely be called upon assist in identifying safety concerns, assessing health, implementing biosecurity measures, formulating/prescribing treatment protocols comparable what we have seen with honeybee institution veterinary feed directives (VFDs). Similar other agricultural markets, high densities management practices put at risk for infectious diseases. Veterinarians interested working these species need become knowledgeable regarding diseases afflicting feeder insect how best diagnose treat pathogens concern. Using edible cricket as an example, review highlight health production issues while drawing similarities livestock operations. If insects-as-feed-and-food going viable, involvement essential ensure that can used safe source all.

Heterogeny in cages: Age-structure and timing of attractant availability impacts fertile egg production in the black soldier fly,Hermetia illucens

Abstract Adult behavior is a growing area of interest for those researching the black soldier fly, Hermetia illucens (L.) (Diptera: Stratiomyidae), which affected by underlying demography and spatiotemporal patterns. This greenhouse experiment examined interaction age-related effects that can accrue within heterogeneous breeding populations potential benefits delaying an oviposition attractant in concert with restricting mean cohort age. The impetus this investigation was because if flies are introduced into mating-cage before old removed or culled, creates population mixed-age mating-status. We hypothesized potentially reduces quality among available mate choices, especially small cages where might not be able to spatially segregate. Metrics fitness included copulation frequency, weight eggs produced, hatch percentage. “Same”-aged cohorts (maximum 4-d-old at introduction) performed better than highly (1-16-d-old) “mixed” mating 2.32-times more frequently laying 6.58-times were 1.17-times fertile, despite 1.41 fewer observed events. Delaying had significant effect on egg collection led 1.25-times higher yields same- age compared mixed-aged no effect. These results likely due part immediate desire lay older females as well haphazard cage material, 2.09-times mixed cohorts. highlight importance constraining removing adults from improve manipulate behavior.
