The cephalic extracts of two species in the stingless bee genusOxytrigona were analyzed. Extracts made in diethyl ether, and then derivatized with diphenyldiazomethane, revealed large quantities of formic acid, potentially a major defensive secretion of this stingless bee group. We additionally identify several hydrocarbons, aldehydes, ketones, and acetates. Novel diketones identified by others were detected in both species. 
Nest plundering allomones of the fire beeTrigona (Oxytrigona) mellicolor
TLDR
Ten volatile compounds derived from the cephalic glands of the fire beeTrigona (Oxytrigona)mellicolor were bioassayed for possible allomonal activities facilitating nest plundering, causing the honeybeeApis mellifera to display avoidance behavior and reduced defensive behavior. Expand
Stingless Bees (Hymenoptera: Apidae: Meliponini) in Oriental Mountains Cementeries from Colombia
In 11 cemeteries of Cundinamarca and Meta (Colombia) departments we found 203 nests of stingless bees pertaining to 15 species. The majority of the found nests (61%) belong to genus NannotrigonaExpand
Propolis of stingless bees: A phytochemist's guide through the jungle of tropical biodiversity.
TLDR
This review summarises and discusses the available data about the chemical composition of propolis from the stingless bee species (Meliponinae) of the Americas, Asia and Australia, published after 2007 and results in the discovery of new natural molecules, some of them with valuable bioactivity. Expand
Defensive repertoire of the stingless bee Melipona flavolineata Friese (Hymenoptera: Apidae)
TLDR
The results confirm the mandibular gland as a source of alarm pheromone for this specie and also the chemical triggering of defensive response for the known cleptoparasite L. limao. Expand
Oxytrigona tataira (Smith) (Hymenoptera: Apidae: Meliponini) as a collector of honeydew from Erechtia carinata (Funkhouser) (Hemiptera: Membracidae) on Caryocar brasiliense Cambessèdes (Malpighiales: Caryocaraceae) in the Brazilian Savanna
TLDR
Observations of Oxytrigona tataira (Smith) collecting honeydew from Erechtia carinata on Caryocar brasiliense Cambessedes in a cerrado sensu stricto fragment from Brazilian Savanna are presented as a novel bee-treehopper interaction. Expand
Stingless Bees: Chemical Differences and Potential Functions in Nannotrigona testaceicornis and Plebeia droryana Males and Workers
TLDR
Cuticular wax, abdominal and cephalic extracts of foraging workers and males of Nannotrigona testaceicornis and Plebeia droryana, from the “Aretuzina” farm in São Simão, SP, Brazil, were analyzed by GC-MS and found that these compounds do not function as alarm or recruitment pheromones. Expand
Taxonomic exploration of Neotropical Microdontinae (Diptera: Syrphidae) mimicking stingless bees.
TLDR
Several species of Neotropical Microdontinae (Diptera: Syrphidae) are mimics of stingless bees and are treated as different genera, with some considerations on mimicry as a possible drive for speciation. Expand
Mandibular gland secretions of meliponine worker bees: further evidence for their role in interspecific and intraspecific defence and aggression and against their role in food source signalling
TLDR
The role of the mandibular gland secretions of Meliponini is confirmed in nest defence and experiments provide strong evidence against their role in food source signalling. Expand
Karyotypic description of the stingless bee Oxytrigona cf. flaveola (Hymenoptera, Apidae, Meliponina) of a colony from Tangará da Serra, Mato Grosso State, Brazil
TLDR
The aim was to broaden knowledge on the cytogenetics of the subtribe Meliponina, by furnishing cytogenetic data as a contribution to the characterization of bees from the genus Oxytrigona by studying members of a colony from Tangará da Serra, Mato Grosso State, Brazil. Expand
Stingless bee floral visitation in the global tropics and subtropics
TLDR
A database of reported associations (flower visits) between stingless bees and plants, from studies that have made either direct observations of foraging bees or analysed the pollen stored in nests supports the view that stingless Bees play an important role in the ecosystems of the global tropics and subtropics as pollinators of an exceptionally large and diverse number of plants.

Biosynthesis of formic acid by the poison glands of formicine ants.
TLDR
The uniqueness of the Poison gland system is that it accumulates formic acid to large extent, yet avoids its cytotoxicity, made possible by a combination of the biochemical characteristics of the pathway and the special morphological features of the poison gland. Expand
