This is the third part of a series on various taxonomic matters regarding Neotropical stingless bee genus Scaptotrigona Moure (Apinae: Meliponini). Here, an infrageneric classification established, with Sakagamilla resurrected for tubiba group, while Moure, s.str., encompasses postica group. A key to subgenera presented and five new are established: Eoscaptotrigona Engel, subgenus; Dasytrigona ...

OBJECTIVE To investigate the synergic antibacterial activity of garlic and tazma honey against standard and clinical pathogenic bacteria. METHODS Antimicrobial activity of tazma honey, garlic and mixture of them against pathogenic bacteria were determined. Chloramphenicol and water were used as positive and negative controls, respectively. Minimum inhibitory concentration (MIC) and minimum ba...

Sexual selection predicts that individuals competing for access to sexual partners should maximize their chances of mating by looking for sites where the chances of finding partners are more likely to occur. However, males of stingless bees have been observed sharing nonspecific reproductive aggregations. This uncommon behavior appears to confer no obvious increase of individual fitness. It has...

Amber and copal are renowned for preserving insects and other inclusions with lifelike fidelity. However, due to their frozenin-time nature, they are taxonomically subequal to Recent insects, which commonly require dissection in order to identify them to species level. This can be overcome to a degree through digital dissection using computed tomography, but this technique is time consuming, ex...
