Predicted mating systems are provided in line with the 4 procedures suggested within our symptomatic approach (e.g., mating facts, level of spots, patch development, and you can connect perseverance)
Forecast mating options are provided in accordance with the 4 tips recommended within symptomatic approach (elizabeth.grams., mating facts, amount of patches, area development, and you will connect persistence)
To help you estimate the age of sampled queens, we categorized all of the anybody from the cumulative wing don ). Queens have been classified with the after the categories: (1) “recently mated,” undamaged wings (0–dos wear scratching); (2) “young,” quite used wings (3–5 wear scratching); (3) “middle-aged,” worn wings (6–several don scratching); and you will (4) “old,” most used wings (?a dozen don ples, data for the wing wear just weren’t compiled ergo are known as “no information.”
grams., solitary pair otherwise several pairs)-if the there’s one few, the new queen are sensed singly mated, if there were several pairs, the king was sensed remated; (3) effort off mating plug attachment according to the combined pointers out-of the clear presence of melanized patches, the existence of a plug inside queen, and inferred age-in the event that melanized spots was in fact present, but plug was missing, no matter what king many years, the fresh new plug are sensed short term, however, if the plug are establish, no matter queen age, it is actually thought a lengthy-identity connect; (4) recently mated queens (i.elizabeth., has just mated queens coming back from an excellent nuptial journey; Kerr mais aussi al. 1962; Weil Silva ainsi que al. 1972), was basically those individuals with a connected mating plug, although not yet physogastric. We don’t get a hold of any physogastric queens having melanized patches and you can connected mating plugs (comprehend the “Results” section).
We removed the last part of the stomachs of 1 private for each gender for every single varieties (regarding tergum T-IV and you may sternum S-IV in women; and out of tergum T-VI and you may sternum S-VI when you look at the men; Additional Figure S1 )
I opposed a man genital pill regarding Meters. fasciculata with its sleeping status (in the male’s system) along with their triggered condition as a great mating plug (for the woman’s vaginal chamber) to understand its functional morphology. I demonstrated and represented the working morphology in line with the differences of initially and you will finally ranks of one’s after the male genital formations: the penis regulators, the newest gonocoxites, while the gonobase. Immediately following having the ability to characterize this new resting county while the triggered state of your mating plug, we suggested advanced claims on the formations of your genital medicine in order to depict its changes within the plug activation. Likewise, i changed the fresh literary works to gather data to your male vaginal morphology regarding almost every other genera and you can visually contrast research regarding previous degree to help you our tested types. All of our mix-varieties analysis consisted of a categorized class of one’s cock valves element (sturdy otherwise slim), curve (good, intermediary, otherwise weakened), and you will spatha’s advancement (setup, reduced, otherwise missing) ( Supplementary Dining table S2 ).
To choose mating status from queens we experienced cuatro points: (1) the presence of melanized spots regarding girls genital chamber-when the introduce, queen try thought mated, otherwise, are felt unmated; (2) level of matched up melanized spots (e
We opposed the newest genital morphology anywhere between pre- and you will article-mating, from both men and you may queens from Meters. fasciculata, knowing the fresh values of plugging process. I find the variety Meters. fasciculata to rebuild the latest method out-of mating plug while the all of the mated queens within this variety employed mating plugs aside from their age (comprehend the “Results” section). Hence, we think this species invited me to evaluate females to provide the mating plug while in the their most likely activated standing. We opposed some step three–5 specimens belonging to different groups-(1) newly emerged males out-of brood combs; (2) sterile penisless people; (3) physogastric queens having mating connect; and (4) virgin queens. I upcoming revealed and you may depicted the functional morphology between your initial and you may latest amount out-of mating. To accomplish this, we accessed the vaginal region of lady and you will men and you may dissected for every single specimens’ metasoma. Just after deleting it, we manually established the fresh marks that with tweezers in order to holding apart brand new critical sternum and you can tergum. For males, i open their genital product because of the totally removing they from the dissected part. Shortly after structures were dissected and you will unwrapped, we depicted him or her from the drawings. According to research by the photos regarding a whole band of mating connect says, we speculate from the male and female genital motions to explain the newest hypothetical setting and action from plugs inside stingless bee mating.
