| The corn is a plantation attacked by a lot of pests, mainly by Caterpillar Spodoptera frugiperda (Smith), producing serious damages in the plants, occasioning unproductiveness. Thus, the goal of this research was to verify the predation of Polistes simillimus (Zikán, 1951) wasps on this pest of a corn plantation using the wasps colonies as a efficient form of this pest management. The present research was developed in a area in the Piracicaba county, São Paulo (22º43'S, 47º38'W), during the period of november/1995-march/1996, introducing 20 P. simillimus colonies in artificial wood shelters around of 5 plots of com, to accompany the foraging activity of the wasps and the development of the wasps colonies. Spodoptera frugiperda (23,07%) was the main prey... |

| Sudies of species survey are important to know the available natural resources and to get useful information about the ecological characteristics of a specific area. There are not studies, on this issue, related to social wasps, in the Triângulo Mineiro region. The present study describes the diversity of species found in fragments of the cerrado region in Uberlândia, MG, and their temporal distribution. The field study was conducted from October 2003 to September 2004, and 43 samplings were carried out using active searching (24) and point sampling (19) methodologies. Twenty-nine species were found in 10 genera, Polybia and Polistes corresponding to 51.5% of the total listing. Mischocyttarus cerberus styx Richards represented 26.5% of the total... |

| A criação de Galleria mellonella L. em laboratório é de grande importância para a multiplicação de nematóides entomopatogênicos, fundamental para estudos de controle biológico. O objetivo deste estudo foi verificar o efeito de três diferentes condições térmicas sobre os estágios imaturos desse inseto, possibilitando a sincronização de sua produção. Foram empregadas duas etapas na criação, utilizando núcleo de incubação para desenvolvimento dos ovos e recipientes circulares de alumínio para desenvolvimento de larvas e pupas. A duração dos estágios imaturos foi inversamente proporcional à temperatura em todos os bioensaios executados. Os períodos de incubação foram de 13,4 dias a 22ºC, 8,3 a 27ºC e 6,8 a 32ºC. Para os períodos de desenvolvimento larval foram... |

| A species' mating system depends on its spatial distribution and temporal availability of mating opportunities, as well as on the resources that create these opportunities. In addition, for many species, courtship is driven by specific behaviors that precede and follow copulation. Although Sphex ingens is a taxonomically well known species of digger wasp, its ecology and behavior remain poorly known. Hence, we analyzed patterns and trends of sexual behavior, in order to understand whether courtship can persist in a polygamous mating system. We monitored by video wasp populations in Ilha Grande, southeastern Brazil. Based on the observed behaviors, we calculated stochastic probabilities with a Markov chain to infer on behavioral trends. We recorded four... |

| The social wasps are predators of several species of insects and the study of their preys can reveal their potential for programs of biological pest control. During the period of September 2000 to January 2002, were accomplished 70h of collections of the preys captured in twelve nests of Polybia platycephala Richards, placed in urban areas of Juiz de Fora municipality, Minas Gerais State, Brazil. The preys captured by P. platycephala include five orders of insects: Diptera (33.4%), Lepidoptera (28.6%), Hemiptera (12.0%), Hymenoptera (9.4%) e Coleoptera (7.2%). The mean weight of protein charge carried by the wasps was 1.9 ±1.6mg (n = 34, 0.3 - 6.2 mg), and the mean of protein transported per day was 22.8 mg. According to the results, we could estimate that... |

| 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... |

| O objetivo deste trabalho foi determinar os recursos forrageados por Polistes versicolor em área de reflorestamento com eucalipto e identificar as presas forrageadas. No período de janeiro a dezembro de 2007, foram realizadas 24 observações da atividade forrageadora de colônias de P. versicolor presentes em um reflorestamento de eucalipto, em Juiz de Fora, MG, totalizando 240 horas de registros. Durante as dez horas de observação diária, foram registrados e qualificados, a cada 30 minutos, os retornos das operárias para a colônia. Foram registrados 1.809 retornos, dos quais 51,63% foram com néctar; 6,85%, com água; 4,7%, com fibra vegetal; 17,41%, com presas; e 19,40%, sem recurso forrageado (improdutivos). As operárias de P. versicolor predaram... |
