First record of emergency queen rearing in stingless bees (Hymenoptera, Apinae, Meliponini)
Summary: This paper presents the first record of emergency queen rearing in stingless bees. The main steps of the event in Trigona (Frieseomelitta) varia (Lepeletier) queenless colonies are: 1)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
SUMMARY Like ants and termites some species of stingless bees (Meliponini), which are very important pollinators in the tropics, use pheromone trails to communicate the location of a food source. WeExpand

Low mating frequency of queens in the stingless bee Scaptotrigona postica1 and worker maternity of males
Kin selection models of intracolonial conflict over the maternity of males predict that social hymenopteran workers should favour the production of sons and nephews over brothers when the effectiveExpand

Agelaia vicina, a Swarm-Founding Polistine with the Largest Colony Size among Wasps and Bees (Hymenoptera: Vespidae)
-Since von Ihering (1903, 1904), Agelaia vicina is famous for its huge nests, but no detailed account has been published. Several nests examined by us were mainly built in shelters but some were halfExpand

Nestmate recognition in the stingless bee Frieseomelitta varia (Hymenoptera, Apidae, Meliponini): sources of chemical signals
Social insects use cuticular lipids for nestmate recognition. These lipids are chiefly hydrocarbons that can be endogenously produced or acquired from the environment. Although these compounds areExpand

Exploitation of carbohydrate food sources in Polybia occidentalis: social cues influence foraging decisions in swarm-founding wasps
An efficient exploitation of carbohydrate food sources would be beneficial for social wasp species that store nectar within their nest. In the swarm-founding polistine wasp Polybia occidentalis, weExpand

Caste Flexibility and Variation according to the Colony Cycle in the Swarm-founding Wasp, Parachartergus fraternus (Gribodo) (Hymenoptera: Vespidae: Epiponini)
Abstract Differences between castes and related aspects in Parachartegus fraternus (Gribodo) have been studied in various stages of the colony cycle. Five colonies from three colony developmentExpand

Behavioral interactions among females of Halictus (Seladonia) lanei (Moure) (Hymenoptera: Halictidae)
Halictus (Seladonia) lanei (Moure) has the most extreme cephalic dimorphism, and thereby presumably also caste dimorphism, among the halictine bees. Previously known only from a few sites in Brazil,Expand

Food profitability affects intranidal recruitment behaviour in the stingless bee Nannotrigona testaceicornis
Does the food’s sugar concentration affect recruitment behaviour in the stingless bee Nannotrigona testaceicornis? We recorded intranidal forager behaviour while offering sugar water of constant,Expand
