15 mins to 2 hrs are kept for drosophila mating

Mating duration used by different research groups: 15-30 mins (https://www.sciencedirect.com/science/article/pii/S0022191012002259#s0025) 30 mins (https://www.nature.com/articles/ncomms12322) 90 minutes (https://academic.oup.com/beheco/article/22/1/184/232467?login=false) 2 hours (https://onlinelibrary.wiley.com/doi/full/10.1111/j.1420-9101.2010.01973.x) ~15 mins for mating latency + copulation time (https://academic.oup.com/jinsectscience/article/11/1/67/2492817?login=false#90814333)

AMPs regular endosymbionts

"bacteriome highly expresses the coleoptericin A (colA) antimicrobial peptide (AMP), which was shown to prevent endosymbiont escape from the bacteriocytes." "This work provides a striking example of how a conserved immune pathway, initially described as essential in pathogen clearance, also functions in the control of mutualistic associations."  https://microbiomejournal.biomedcentral.com/articles/10.1186/s40168-017-0397-9

Nucleoproteins

Nucleoproteins are complex structures made up of proteins and nucleic acids, such as DNA or RNA.  Histone, protamines, ribosomes,  Spermatids are the cells which are produced from the testes as a result of spermatogenesis .  The spermatids develop into spermatozoa or sperms by the process of spermiogenesis .

Lactobacillus plantarum and Acetobacter pomorum increases frut fly developmental pace

D. melanogaster gut microbiome, particularly Lactobacillus plantarum and Acetobacter pomorum, increases the pace of host development (Shin et al., 2011; Storelli et al., 2011).

Lab flies have lower microbiome diverity than wild flies

Reduced Richness and Diversity : Lab-raised flies exhibit significantly lower richness and diversity of bacteria compared to wild-caught flies. Specific Strains : Laboratory flies have bacterial strains closely related to those from previous studies, with five strains being >99% identical to previously identified cultured isolates of D. melanogaster. Enterococcus, which was previously found to comprise nearly 50% of the lab bacterial microbiome, is virtually absent in current lab samples. https://journals.plos.org/plosgenetics/article?id=10.1371/journal.pgen.1002272#pgen-1002272-g002
