Influência do ambiente no desenvolvimento de colônias iniciais de formigas cortadeiras (Atta sexdens rubropilosa)
(2013-08-01)
Annually, mature colonies of Atta ants produce winged males and females, where leave the colony in which they were produced to form new colonies and thus continue the species perpetuation. The foundation of Atta spp. ...
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 modified ant colony optimization algorithm modeled on tabu-search methods
(Institute of Electrical and Electronics Engineers (IEEE), 2006-04-01)
An earlier model underlying the foraging strategy of a pachycodyla apicalis ant is modified. The proposed algorithm incorporates key features of the tabu-search method in the development of a relatively simple but robust ...
Mechanism of leaf‐cutting ant colony suppression by fipronil used in attractive toxic baits

Brood care and male behavior in queenless Acromyrmex subterraneus brunneus (Hymenoptera: Formicidae) colonies under laboratory conditions
(2006-11-10)
In this study we describe and quantify the brood care performed by workers in queenless colonies of the leaf-cutting ant Acromyrmex subterraneus brunneus. Fifteen behavioral acts were recorded in the three colonies studied. ...
Immatures of Nesticodes rufipes (Araneae, Theridiidae) Causing Considerable Damage to Ant Colonies in the Laboratory
(California State University, 2009-01-01)
Here we report the frequent occurrence of Nesticodes rufipes (Lucas) (Araneae; Theridiidae) immature spiders inside laboratory colonies of various ant species. It was the only spider species frequently found to invade the ...
Multiple queens in founding colonies of the neotropical ant Pachycondyla striata smith (Formicidae: Ponerinae)
(Neotropical Entomology, 2017)
Entomopathogens isolated from invasive ants and tests of their pathogenicity
(2012-08-17)
Some ant species cause severe ecological and health impact in urban areas. Many attempts have been tested to control such species, although they do not always succeed. Biological control is an alternative to chemical control ...
