Performance
To help you pic copulatory scratching as well as the men vaginal morphology of any kinds, we reached female and male genitalia using dissections. For this reason, i tested additional queens (both virgin and you may physogastric mated of them) and extra freshly came up men of any variety, following the exact same sampling standards previously revealed (comprehend the earlier in the day areas). We after that dissected each specimens’ metasoma to get into the brand new genital part of females and you will men. Just after dissection, i instantly snap such formations to be 
sure the integrity out of membranous buildings, especially in girls. Dissections observed the method previously discussed within the Genital practical morphology, hypothesized plugging actions and mating positions. In the long run, i utilized a beneficial Leica DM one thousand stereomicroscope, combined with an attracting tube to arrange the newest pictures of mating couple (?20 magnification, Vaginal practical morphology, hypothesized plugging tips and mating ranks) additionally the vaginal functional morphology (?80 magnification, Genital practical morphology, hypothesized plugging procedures and you will mating ranks). I vectorized and you may managed this type of design playing with a photo publisher software. We and used a beneficial Leica DFC420 digital camera linked to an effective Leica M205A stereomicroscope to create high-quality images of females and guys genitalia (?step one.0 contact and ?fifty magnification, Area dos.4). First, i grabbed multifocus color pictures, after that we piled him or her in one single visualize utilizing the Leica application room adaptation step three.4.step one. I constant this process for each and every genitalia (male and female) off all sampled stingless bee varieties, however, you to, Meters. melapling constraints.
Traumatic mating from inside the stingless bees
Zero melanized spots was sensed for the examined unmated virgin queens. In most kinds, physogastric queens exhibited melanized patches on their membranous pockets ( Table step 1), with the exception of Meters. fasciculata ( Shape 1). The fresh new membranous pockets was basically the actual only real area that have copulatory scratching. When you look at the for each mated king, spots were constantly matched, matching the inferred status of your set of cock valves into the a man genital product. Patches was in fact found on per wallet, and you can symmetrically positioned ( Contour step one). Concurrently, melanized patches looked like long lasting, once the i observed her or him for the mated queens various ages, based on our wing wear category ( Secondary Shape S3 ).
Women genital chamber, pattern off copulatory scratches, and ventral view of male vaginal products away from F. longipes, P. minima, Scaptotrigona aff. postica, Melipona flavolineata, Meters. seminigra, and you will Meters. fasciculata. Away from remaining so you’re able to proper, images inform you the brand new genital chamber of virgin queens, new vaginal chamber out of mated queens, and also the melanized spots found on queens, which happen to be conveyed because of the light arrows in the third column regarding photographs. Singly mated queens let you know one group of melanized spots, revealed to have F. longipes, P. minima, S. aff. postica, Meters. flavolineata, and you will M. seminigra; otherwise a lengthy-identity attached plug, simply found in Yards. fasciculata. Remated Meters. seminigra queens, indicated of the black asterisk, tell you several sets from melanized spots and you can central patches. In the right hand set of images, male tablets is actually shown due to the fact activated mating plugs simply for Melipona types, indicating turned dick regulators. We together with inform you an inactivated mating plug for M. fasciculata, due to the fact expressed by the white asterisk. Black colored pubs represent a level out-of 0.5 mm. That it contour has photographs away from six off our very own seven analyzed varieties (select Matter and techniques).
Lady genital chamber, trend regarding copulatory marks, and you will ventral look at male vaginal medicine off F. longipes, P. minima, Scaptotrigona aff. postica, Melipona flavolineata, Yards. seminigra, and you may M. fasciculata. Out of remaining in order to right, photographs inform you the fresh new genital chamber out of virgin queens, the vaginal chamber of mated queens, additionally the melanized spots available on queens, which happen to be shown by light arrows on 3rd line off photo. Singly mated queens reveal one group of melanized spots, revealed to own F. longipes, P. minima, S. aff. postica, Yards. flavolineata, and you may M. seminigra; or a lengthy-identity affixed plug, simply found in Yards. fasciculata. Remated Yards. seminigra queens, indicated because of the black asterisk, tell you several sets regarding melanized spots and main patches. About right-hand number of photo, men medications is displayed due to the fact activated mating plugs simply for Melipona variety, indicating rotated dick regulators. We also reveal a keen inactivated mating connect getting M. fasciculata, while the indicated by white asterisk. Black colored pubs show a level of 0.5 mm. That it profile has pictures away from six out-of all of our 7 examined varieties (see Point and techniques).
