Hygienic behavior; Plebeia remota; Stingless bees

We investigated hygienic behavior in 10 colonies of Plebeia remota, using the pin-killed method. After 24 h the bees had removed a mean of 69.6% of the dead brood. After 48 h, the bees had removed a mean of 96.4% of the dead brood. No significant correlation was found between the size of the brood comb and the number of dead pupae removed, and there was no apparent effect of the ... more

Cuticular hydrocarbons; Dufour’s gland; Kin recognition; Melipona bicolor; Pheromone; Stingless bee

In social insects, cuticular hydrocarbons are involved in species, kin, caste and nestmate recognition. Gas chromatography and mass spectrometry were used to compare the cuticular hydrocarbon composition of workers, males and queens of Melipona bicolor. The cuticular hydrocarbon composition of this species was found to consist mainly of C23, C25:1, C25, C27:1, C27, C29:1 and C29 ... more

male production; Plebeia remota; queen production; Stingless bees; worker production

Queen, male and worker production was studied during one year in three Plebeia remota colonies from Atlantic Rainforest in Cunha, São Paulo State, and two from a subtropical Araucaria forest in Prudentópolis, Paraná State. All the colonies were kept in São Paulo city during our study. Plebeia remota has reproductive diapause during autumn and winter, which makes its biology ... more

pollen analysis; pollen exploitation; sampling methods; Stingless bees

Pollen counts from samples taken from storage pots throughout one year (from October to September) were adjusted by Tasei’s volumetric correction coefficient for the determination of pollen sources exploited by two colonies of Nannotrigona testaceicornis in São Paulo, Brazil. The results obtained by this sampling technique for seven months (December to June) were compared with those ... more

chemical communication; hydrocarbons; Schwarziana quadripunctata; social insect; Stingless bees

Chemical communication is of fundamental importance to maintain the integration of insect colonies. In honey bees, cuticular lipids differ in their composition between queens, workers and drones. Little is known, however, about cuticular hydrocarbons in stingless bees. We investigated chemical differences in cuticular hydrocarbons between different colonies, castes and individuals of different ... more

Molecular markers; Single sequence repeats; Stingless bees

Many factors have contributed to reductions in wild populations of stingless bees, such as: deforestation, displacement and destruction of nests by honey gatherers, as well as use of insecticides and other agrochemicals. All of these can potentially affect the populational structure of native species. We analyzed genetic variability and populational structure of Melipona scutellaris, ... more

Behavior; Communication; Mixed colony; Nestmate recognition; Stingless bees

We describe a case of a spontaneously established mixed colony of two species of stingless bees. The host colony of Scaptotrigona depilis, an aggressive bee that forms large colonies, was invaded by workers of Nannotrigona testaceicornis, a smaller bee that forms small colonies. The host colony and the invading species colony were maintained in next boxes about 1.5 m apart. ... more

greenhouse; pollination; Stingless bees; strawberry

We investigated the success of two stingless bee species in pollinating strawberries in greenhouses. Three greenhouses and one open field area were used; one greenhouse had only strawberry plants (control), another (G1) had three colonies of Scaptotrigona aff. depilis and another (G2) had three colonies of Nannotrigona testaceicornis. In the open field area, the ... more

Hygienic behavior; Melipona beecheii; Meliponini; Scaptotrigona pectoralis; Stingless bees

Hygienic behavior, a trait that may confer resistance to brood diseases in the honey bee Apis mellifera, was studied in two species of stingless bees in Mexico. Eight colonies each of Melipona beecheii and Scaptotrigona pectoralis were tested for hygienic behavior, the removal of dead or diseased brood, by freeze killing a comb of sealed cells containing pupae. Both ... more

AFLP; Population differentiation; Species-specific marker; SSCP; Stingless bees; Trigona collina

A molecular maker for authenticating species origin of the stingless bee (Trigona collina) was developed. Initially, amplified fragment length polymorphism analysis was made of 11 stingless bee species using 64 primer combinations. A 316-bp band found only in T. collina was cloned and sequenced. A primer pair (CUTc1-F/R) was designed and tested for species-specificity in ... more
