Cytogenetic Analysis in Trigona spinipes Fabricius (Hymenoptera, Meliponina) Reveals Intraspecific Variation

Neotropical Entomology, 2021
Trigona spinipes Fabricius is a stingless bee with wide geographical distribution. Although being sometimes considered an agricultural pest, in fact, it has great pollinating potential, and therefore economic interest. Conventional and molecular cytogenetic techniques have been little used to verify genetic diversity in this species, despite its ...

Behaviour of drones in Melipona (Apidae, Meliponinae)

Insectes Sociaux, 1997
The behaviour of drones of different species of Melipona was studied in Costa Rica and on Tobago. Drones of all species behaved very similarly. The intranidal behavioural analysis indicates that drones spent most time on standing, walking, stirring the antennae and self-grooming.

Melissopalynology for stingless bees (Apidae: Meliponinae) from Venezuela

Journal of Apicultural Research, 1994
SUMMARYPollen spectra were obtained for honey samples taken from the nests of 48 Melipona spp. and 20 other stingless bee species at 23 locations in Venezuela from 1987 to 1989. The order of abundance for dominant pollens in Melipona spp. honeys was: Mimosa pudica gr, Scrophulariaceae, Machaerium gr., Avicennia, Myrtaceae, Mimosa scabrella gr., Cassia,

Pollen Harvest by Stingless Bee Foragers (Hymenoptera, Apidae, Meliponinae)

Grana, 1994
Abstract Data on pollen load capacity and flower constancy are discussed for nine stingless bee species. The foragers present high levels of flower constancy and often visit only one flower type (on average 97% of bee foragers), rarely a few flower types (on average 3% of bee foragers), during the same foraging trip.
