Phylogenetic analysis of the corbiculate Apinae based on morphology of the sting apparatus (Hymenoptera: Apidae)

Cladistics, 2007
AbstractThis study aimed to test the various competing hypotheses regarding the relationships among the four tribes of corbiculate apine bees (Euglossini “orchid bees”, Bombini “bumble bees”, Meliponini “stingless bees”, and Apini “honey bees”) with a completely new set of previously unstudied morphological characters derived from the sting apparatus ...

Phylogeny of the orchid bees (Hymenoptera: Apinae: Euglossini): DNA and morphology yield equivalent patterns

Molecular Phylogenetics and Evolution, 2004
Orchid bees (Euglossini) are spectacular long-tongued Neotropical bees important in the pollination of Neotropical long-corolla flowers, particularly some orchids. Besides remarkably long tongues, males in particular exhibit other flower-related adaptations, including setal brushes on the foretarsi used for rasping the petals of orchids while ...

Behavioral Phylogeny of Corbiculate Apidae (Hymenoptera; Apinae), with Special Reference to Social Behavior

Cladistics, 2002
The phylogenetic relationships among the four tribes of corbiculate bees (Euglossini, Bombini, Meliponini, and Apini) are controversial. There is substantial incongruence between morphological and molecular data, and the single origin of eusociality is questionable.

First record of emergency queen rearing in stingless bees (Hymenoptera, Apinae, Meliponini)

Insectes Sociaux, 2002
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) construction and provisioning of an auxiliary cell in close contact to that housing a late feeding-stage larva; 2) construction of a connection between the two cells; 3)

Could Tetragonisca angustula Latreille (Apinae, Meliponini) be effective as strawberry pollinator in greenhouses?

Australian Journal of Agricultural Research, 2004
We evaluated the contribution of the stingless bee Tetragonisca angustula as a strawberry pollinator using primary flowers of the ‘Oso Grande’ cultivar. We applied 4 pollination treatments: open-pollination in the field, T. angustula pollination inside a greenhouse, and spontaneous self-pollination in the field and greenhouse.

Historical Biogeography of the Meliponini (Hymenoptera, Apidae, Apinae) of the Neotropical Region

2012
The Meliponini have a pantropical distribution (Indo-Australia, the Neotropics and Africa-Madagascar) which includes continental disjunctions unique among the Apidae, revealing a complex history of vicariance events of great antiquity. The trait of disjunction by vicariance permits the inference that Meliponini possibly had their origin on the ancient ...

Effect of Larval Food Amount on Ovariole Development in Queens ofTrigona spinipes(Hymenoptera, Apinae)

Anatomia, Histologia, Embryologia, 2005
SummaryCaste determination inTrigona spinipesFabricius (Hymenoptera, Apidae, Meliponini) is trophogenic. Larvae that eat about 360 μl of food become queens, while those who consume 36 μl develop into workers. We studied the effect of larval nutrition on the number and length of ovarioles and on ovarian development in fifth instar larvae, white eyed ...
