Nest architecture and population dynamics of the ponerine ant Ectatomma edentatum (Hymenoptera, Formicidae)
(2001-12-01)
Twelve nests of Ectatomma edentatum (Hymenoptera, Formicidae) were collected from January to December 1996, in Rio Claro, SP, southeastern Brazil. This species excavates their nests up to 1, 10m deep, containing 2, 3, or ...
A method for rearing immature stages of Apis melifera outside the colony (Hymenoptera: Apidae)
(2002-01-01)
The objective this work is to define an effective method for following the development of immatures of Apis mellifera from metamorphosis to the emergence of the adult, under conditions allowing the application of diverse ...

Dominance hierarchy in different stages of development in colonies of the primitively eusocial wasp Mischocyttarus cerberus styx (Hymenoptera, Vespidae)
(2001-12-01)
In primitively eusocial insect societies, reproductive division of labor is established by dominance-submission interactions which determine a linear dominance hierarchy. As previously observed for other species, in ...

Ant colony optimization algorithm for a Bi-criteria 2-stage hybrid flowshop scheduling problem
(Journal of Intelligent Manufacturing, 2011)
We consider the problem of scheduling jobs in
a hybrid flowshop with two stages. Our objective is to minimize both the makespan and the total completion time of
jobs. This problem has been little studied in the literature. ...
Morphological caste differences and non-sterility of workers in Brachygastra augusti (Hymenoptera, Vespidae, Epiponini), a neotropical swarm-founding wasp
(New York Entomological Soc Inc, 2003-12-01)
Morphological caste differences and ovary conditions were analyzed in four colonies of Brachygastra augusti collected in different stages of the colony cycle. Differences between castes are distinct suggesting pre-imaginal ...
