Nest materials and some chemical characteristics of nests of a New World swarm-founding polistine wasp, Polybia paulista (Hymenoptera Vespidae)
TLDR
The present result supports the view that amino acid composition of the protein in nests reflects phylogenetical relationships among wasps.
Agelaia vicina, a Swarm-Founding Polistine with the Largest Colony Size among Wasps and Bees (Hymenoptera: Vespidae)
TLDR
The nest size and colony size of A. vicina is evidently unrivalled among all wasps and bees.
Low mating frequency of queens in the stingless bee Scaptotrigona postica1 and worker maternity of males
TLDR
Genetically analysed 20 worker and 20 male pupae from each of 10 colonies of the stingless bee Scaptotrigona postica use six microsatellite loci and demonstrate queen monandry in eight nests and apparent low me in the other two, broadly in agreement with predictions from kin selection theory.
First record of emergency queen rearing in stingless bees (Hymenoptera, Apinae, Meliponini)
TLDR
This paper presents the first record of emergency queen rearing in stingless bees, and in one case, the new gyne started ovipositing at 19 days old.
The cuticular hydrocarbons profiles in the stingless bee Melipona marginata reflect task-related differences.
TLDR
The results showed that cuticular hydrocarbon profiles of workers were composed of alkanes, alkenes and alkadienes that varied quantitatively and qualitatively according to function of workers in the colony.
Nestmate recognition in the stingless bee Frieseomelitta varia (Hymenoptera, Apidae, Meliponini): sources of chemical signals
TLDR
This work used behavioural recognition tests and cuticle chemical investigation to elucidate the role of endogenous and environmentally based cues for nestmate recognition in the stingless bee Frieseomelitta varia and found that although newly emerged workers present specific cuticle patterns according to their nest origin, these compounds are not used for nestmates recognition.
Exploitation of carbohydrate food sources in Polybia occidentalis: social cues influence foraging decisions in swarm-founding wasps
TLDR
It is demonstrated that the decisions of when and where to forage are influenced by information from conspecifics in the swarm-founding polistine wasp Polybia occidentalis, and that the newcomers’ choice on where to collect was strongly influenced by field-based social information.
Caste Flexibility and Variation according to the Colony Cycle in the Swarm-founding Wasp, Parachartergus fraternus (Gribodo) (Hymenoptera: Vespidae: Epiponini)
TLDR
Findings support the occurrence of caste totipotency in Parachartergus fraternus, which is evidently post-imaginally determined and probably taking place according to the colony conditions.
Cuticular hydrocarbons in the stingless bee Schwarziana quadripunctata (Hymenoptera, Apidae, Meliponini): differences between colonies, castes and age.
TLDR
There were significant differences in cuticular hydrocarbons between bees from different colonies, workers of different age and between workers and virgin queens.
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.
