The ant fauna of hospitals: advancements in public health and research priorities in Brazil
Provedor de dados: 92
Autores: Castro,Mariana Monteiro de; Prezoto,Helba Helena Santos; Fernandes,Elisa Furtado; Bueno,Odair Correa; Prezoto,Fábio.
Ants inhabit several types of natural and urban habitats, where they successfully nest. In urban environments, the hospitals should be considered priority for studies, as ants pose risks to human health due to their pathogen carrying potential. We aimed at surveying the literature about studies on ants in hospital settings in Brazil in the past 20 years. We found 40 papers in 22 journals, the first one published in 1993. Among them, 26 papers assessed pathogenic microorganisms on ants. We recorded 59 ant species, being Tapinoma melanocephalumthe most common. The Minas Gerais and São Paulo states had the largest number of published papers. Mato Grosso do Sul and Rio Grande do Sul showed the highest number of species. Exotic ant species were recorded in all...

Field methods for the study of ants in sugarcane plantations in Southeastern Brazil
Provedor de dados: 63
Autores: Souza,Débora Rodrigues de; Stingel,Erich; Almeida,Luiz Carlos de; Lazarini,Marco Antônio; Munhae,Catarina de Bortoli; Bueno,Odair Correa; Archangelo,Claudinei Rogério; Morini,Maria Santina de C.
The harvest of sugarcane is still traditionally done manually with the burning of straw in most cultivated areas in Brazil. However, burning has been gradually eliminated with the relatively recent use of mechanical harvesting. This will result in significant changes in the agroecosystem, as the straw will remain in the field. No investigation on Formicidae found in sugarcane plantations in Southeastern Brazil harvested by this new system has been done yet. Because of their feeding habits, many species of this family may act as predators of several sugarcane pests. In this study, the sampling efficacy of pitfall traps, baits, and underground traps with two types of attractants were evaluated. Pitfall traps gave the largest richness, while abundance was the...

Análise de caracteres morfológicos e comportamentais em abelhas africanizadas, caucasianas e em descendentes dos seus cruzamentos
Provedor de dados: 104
Autores: Malaspina,Osmar; Stort,Antonio Carlos; Bueno,Odair Correa.
Twetve external morphological traits and seven traits of food-gathering behavior were studied in africanized and caucasian (A. m. caucasica), bees. Discriminant analysis showed that neither the length of the fourth segment of the abdomen, nor bee weight can be considered as the traits with the highest discriminatory power between africanized and caucasian bees, with any in-bred bees. In the case of in-bred bees the discriminam traits had a lower interorbital width and time to reach the feeder. Multivariate comparisons between the data of in-bred colonies and twenty hibrid colonies, suggest dominance of the genes group of the africanized subspecies.

Composição da fauna de formigas (Hymenoptera: Formicidae) de serapilheira em florestas semidecídua e de Eucalyptus spp., na região sudeste do Brasil
Provedor de dados: 49
Autores: Mentone,Talita de Oliveira; Diniz,Eduardo Arrivabene; Munhae,Catarina de Bortoli; Bueno,Odair Correa; Morini,Maria Santina de Castro.
Este estudo teve como objetivo avaliar a composição da fauna de formigas de serapilheira em áreas de floresta semidecídua com plantio de eucalipto sem manejo durante diferentes períodos. Foram estudadas quatro áreas, sendo três com eucalipto e uma formada por vegetação nativa; todas estão localizadas no município de Rio Claro (SP), sudeste do Brasil. Em cada área foram coletadas 100 amostras de 1 m² de serapilheira, abrangendo os períodos seco e chuvoso da região. Cada amostra foi submetida a extratores do tipo mini-winkler, onde permaneceram por 48 horas. Foram amostradas 58.410 formigas, distribuídas em 10 subfamílias, 42 gêneros e 120 morfoespécies/espécies. Destas, 85 espécies foram encontradas na floresta semidecídua e 84 na floresta de Eucalyptus...

Evaluation of the possible role of ants (Hymenoptera: Formicidae) as mechanical vectors of nematodes and protists
Provedor de dados: 52
Autores: Villani,Fabio; Morini,Maria Santina de Castro; Franco,Marco Antonio; Bueno,Odair Correa.
Nematodes and protists can be transmitted to humans in many ways and little concern has been given to the mechanical transmission by ants. This study aimed at analysing how the eggs of Ascaris lumbricoides and cysts of Entamoeba coli could be mechanically transmitted to the man by Formicidae. Through the experiments using nests of Tapinoma melanocephalum, Linepithema humile and Monomorium pharaonis reared in the laboratory allied to observations of some 17 ant species in an urban park area in Mogi das Cruzes (SP), it was found that L. humile was capable of carrying eggs of A. lumbricoides both in the field and laboratory conditions (1 worker), as well as was Camponotus rufipes (2), Solenopsis saevissima (1) and Acromyrmex niger (1). The cysts of...
