| 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. |

| 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... |

| 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... |

| 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... |
