SummaryThe stingless bee Trigona (Tetragonisca) angustula has a sophisticated defense strategy against flying insect predators at the entrance of its nest. Groups of worker bees hover on both sides in front of the nest entrance tube, facing a flight corridor leading to the nest. Intruders which enter this corridor are attacked by these bees from the side and from behind and are forced to the ground by biting bees clinging to their wings. T. angustula is subject to predation by Lestrimelitta… 
Robber bees (Lestrimelitta limao) and their host chemical and visual cues in nest defense byTrigona (Tetragonisca) angustula (Apidae: Meliponinae)
TLDR
It is concluded that guard bees recognize L. limao by the major terpenoids of their volatile cephalic secretions, geranial, neral (=citral) and 6-methyl-5-hepten-2-one; other components may fine-tune this recognition.
Hovering guards of the stingless bee Tetragonisca angustula increase colony defensive perimeter as shown by intra- and inter-specific comparisons
TLDR
The hypothesis that T. angustula hovering guards increase the detection perimeter for flying intruders, especially L. limao, is supported and a greater number of attacks by guards occurred when dummies were impregnated with citral, a major component of L. Limao.
First report of hovering guard bees of the Paleotropical stingless bee Tetrigona apicalis (Hymenoptera: Apidae: Meliponini)
TLDR
The use of flying guards for the Paleotropical stingless bee species Tetrigona apicalis (Smith) which is the first known species in the region to incorporate this defense strategy and has a continuous presence unless interrupted by rain.
Ambush Predation of Stingless Bees (Tetragonisca angustula) by the Solitary-Foraging Ant Ectatomma tuberculatum
TLDR
A solitary foraging strategy of the ant Ectatomma tuberculatum is described, on nest guards of the stingless bee Tetragonisca angustula, suggesting an adaptive and targeted predatory strategy aimed at gathering external guard bees as prey from these heavily fortified nests.
Temporal Response of Foragers and Guards of Two Stingless Bee Species to Cephalic Compounds of the Robber Bee Lestrimelitta niitkib (Ayala) (Hymenoptera, Apidae)
TLDR
It is found that even though T. angustula did not react to nestmates’ crushed head, its response towards L. niitkib cephalic compounds was stronger and lasted longer than that of S. mexicana; however, more species must be studied to elucidate any pattern regarding the absence/presence of alarm pheromones and the corresponding response to intruders’ phersomones.
Standing and hovering guards of the stingless bee Tetragonisca angustula complement each other in entrance guarding and intruder recognition
TLDR
It is shown that T. angustula colony entrances are also defended by guards standing on the entrance tube, and the defence reaction was not, however, comparable to the reaction previously reported to citral, the propaganda chemical used by the obligate robber bee Lestrimelitta limao when attacking other bee colonies.
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.
Handling sticky resin by stingless bees (Hymenoptera, Apidae)
TLDR
All parts of stingless bee workers contacting these sticky resins are identified, of special interest are those body parts with anti-adhesive properties to resin, where it can be removed without residues.
Fighting ability and the toxicity of raiding pheromone in an obligate kleptoparasite, the stingless bee Lestrimelitta niitkib
TLDR
It is suggested that the large quantities of MGP used during raiding have led to an unexpected outcome, a semiochemical evolving the additional function of a toxin, and contribute to the ability of Lestrimelitta to rob its victims.
Subtle visits despite guards: Theft from nest of stingless bee (Meliponini) by orchid bee (Euglossini)
TLDR
This note recorded the theft of cerumen and propolis made by a species of the orchid bee, Euglossa annectans Dressler, 1982 (Apidae: Euglossini) from the nest of the stingless bee Tetragonisca angustula (Latreille, 1811).

TLDR
Since Apis mellifera lose their stings as a result of use of the sting in defense, the authors suggest that new methods of defense evolved which do not exact a heavy toll of the colony.

TLDR
A rapid survey of the collection of the ants in the Museum of Comparative Zoology, Harvard University, and some other collections, has turned up additional cases of ants in which, judging now only from externally visible structures, the metapleural gland is absent, nonfunctional, or significantly reduced.

TLDR
The mandibular glands of the stingless bee Lestrimelitta limao secrete a volatile terpenoid which has been identified as citral, and the probable functions of citral are discussed in relation to the biology of L. limao.
