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

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.

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 Nannotrigona

Defensive repertoire of the stingless bee Melipona flavolineata Friese (Hymenoptera: Apidae)

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.

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

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.

Stingless Bees: Chemical Differences and Potential Functions in Nannotrigona testaceicornis and Plebeia droryana Males and Workers

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.

Taxonomic exploration of Neotropical Microdontinae (Diptera: Syrphidae) mimicking stingless bees.

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.

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

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.

Stingless bee floral visitation in the global tropics and subtropics

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.

Karyotypic description of the stingless bee Oxytrigona cf. flaveola (Hymenoptera, Apidae, Meliponina) of a colony from Tangará da Serra, Mato Grosso State, Brazil

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.



Alarm substances of the stingless bee,Trigona silvestriana

2-Nonanol, 2-heptanol, octyl decanoate, and octyl octanoate were identified from the heads of Trigona silvestriana workers and elicited angular flights, landing, and buzzing of guard bees.

Workers ofMelipona fasciata andM. interrupta triplaridis respond to their respective mandibular gland extracts with alarm recruitment and defensive behavior. Workers rapidly exit from the nest

Sociochemicals of bees

The aculeate Hymenoptera include approximately 14 000 species of ants, 16 3000 species of wasps and 20000 species of bees world-wide, which exhibit diversity both in the chemistry of their exocrine secretions and their behaviors.

Comparative Anatomy and Histology of the Alimentary Canal of Adult Apinae

SUMMARYThe alimentary canals of workers of 15 species of social bees, including Apis, Bombus and four genera of meliponids, were compared. The anatomical differences were greater than the

Chemistry of cephalic secretion of fire beeTrigona (Oxytrigona) tataira

Analysis of the volatile compounds derived from cephalic glands of the fire beeTrigona (Oxytrigona) tataira by GC-MS was undertaken and two major components of the mixture were identified as E-hepten-2,5-dione andE-3-nonen- 2,5 -dione.
