So you’re able to pic copulatory marks as well as the men vaginal morphology of each types, we reached female and male genitalia due to dissections. For this reason, we tested additional queens (each other virgin and you can physogastric mated of them) and extra recently came up males of each kinds, pursuing the same testing conditions prior to now revealed (see the previous parts). We after that dissected each specimens’ metasoma to get into the newest genital region of females and people. Shortly after dissection, we instantly snap this type of formations so that the stability of membranous frameworks, particularly in lady. Dissections used the procedure in past times explained in Genital useful morphology, hypothesized plugging measures and mating ranks. Fundamentally, i put an effective Leica DM one thousand stereomicroscope, coupled with an attracting tubing to set up brand new visuals of your own mating few (?20 magnification, Genital useful morphology, hypothesized plugging measures and you may mating ranking) together with vaginal practical morphology (?80 magnification, Vaginal useful morphology, hypothesized plugging actions and you will mating ranking). We vectorized and you can treated such photos playing with an image publisher software. I together with used a beneficial Leica DFC420 digital camera attached to a good Leica M205A stereomicroscope to produce large-solution images of females and you may guys genitalia (?1.0 contact lens and ?50 magnification, Part dos.4). Earliest, we got multifocus colour photos, then we stacked him or her in a single image utilising the Leica software suite adaptation step three.4.1. We repeated this process each genitalia (female and male) out-of most of the sampled stingless bee varieties, but you to definitely, Yards. melapling limits.
Harrowing mating inside the stingless bees
No melanized patches have been imagined into the inspected unmated virgin queens. Throughout types, physogastric queens presented melanized patches on the membranous pockets ( Dining table 1), except for Meters. fasciculata ( Profile 1). The brand new membranous pouches was basically the only part having copulatory marks. In per mated queen, patches was indeed always matched, matching this new inferred reputation of collection of dick regulators when you look at the a man vaginal capsule. Spots were situated on for every single pouch, and you may symmetrically organized ( Shape step 1). On top of that, melanized spots appeared as if permanent, since i noticed him or her within the mated queens various decades, centered on our very own wing wear category ( Supplementary Figure S3 ).
Ladies genital chamber, development from copulatory marks, and you will ventral look at men genital medicine https://www.besthookupwebsites.org/local-hookup/bristol/ out-of F. longipes, P. minima, Scaptotrigona aff. postica, Melipona flavolineata, Meters. seminigra, and you may M. fasciculata. Out-of left to help you proper, photos let you know the fresh new vaginal chamber of virgin queens, new genital chamber out-of mated queens, in addition to melanized spots entirely on queens, being expressed by white arrows on the 3rd column from photographs. Singly mated queens show a single group of melanized spots, found for F. longipes, P. minima, S. aff. postica, Meters. flavolineata, and you can Meters. seminigra; otherwise a lengthy-title affixed plug, only used in Meters. fasciculata. Remated Yards. seminigra queens, expressed by the black asterisk, show several pairs out of melanized spots and central spots. Regarding right hand band of images, male products is presented given that triggered mating plugs just for Melipona types, indicating turned penis regulators. We as well as show an inactivated mating connect having M. fasciculata, because the expressed by the light asterisk. Black bars depict a level away from 0.5 mm. This shape has photographs away from 6 regarding the eight analyzed types (find Procedure and methods).
Female vaginal chamber, pattern regarding copulatory scratches, and you may ventral view of men vaginal drugs out-of F. longipes, P. minima, Scaptotrigona aff. postica, Melipona flavolineata, M. seminigra, and you may Yards. fasciculata. Out-of remaining in order to right, images show this new genital chamber from virgin queens, this new vaginal chamber regarding mated queens, as well as the melanized patches entirely on queens, which happen to be indicated because of the white arrows regarding the 3rd line out-of pictures. Singly mated queens inform you a single group of melanized patches, shown having F. longipes, P. minima, S. aff. postica, M. flavolineata, and M. seminigra; otherwise an extended-term connected plug, merely used in Yards. fasciculata. Remated Meters. seminigra queens, conveyed of the black asterisk, let you know several sets off melanized patches and you will main patches. In the right-hand selection of images, male capsules try demonstrated while the activated mating plugs simply for Melipona species, appearing rotated dick regulators. We as well as show a keen inactivated mating plug to own Meters. fasciculata, because the shown of the white asterisk. Black colored taverns depict a size of 0.5 mm. This figure boasts pictures off six from our very own eight examined variety (get a hold of Thing and methods).
