Ação de Polistes (Aphanilopterus) simillimus Zikán (Hymenoptera, Vespidae) no controle de Spodoptera frugiperda (Smith) (Lepidoptera, Noctuidae) Zoologia
Prezoto,Fábio; Machado,Vera L.L.
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...

Flight range extension in Polistes simillimus Zikán, 1951 (Hymenoptera, Vespidae) BABT
Prezoto,Fábio; Gobbi,Nivar.
The aim of this study was to determine the flight range extension of the social wasps, Polistes simillimus. The results of the 125 wasps-carried out tests originating from 10 colonies in post-emergency stage demonstrated that the flight range extension of P. simillimus was of approximately 150m, resulting in a collection area of about 70.650m² by colony. It suggested wasp's efficiency as a biological control agent.

Nesting substrata, colony success and productivity of the wasp Mischocyttarus cassununga Rev. Bras. entomol.
Castro,Mariana M. de; Avelar,Daniela L. Guimarães de; Souza,André R. de; Prezoto,Fábio.
Nesting substrata, colony success and productivity of the wasp Mischocyttarus cassununga. Colonies of the wasp Mischocyttarus cassununga (von Ihering, 1903) are easily found in urban areas. However, in spite of the massive presence of this species in cities, little is known about its nesting habits, colony success and productivity. The present study aimed at answering the following questions: What are the substrates used for nesting by M. cassununga? What is the main foundation strategy adopted by M. cassununga in urban areas: a solitary female or associative foundation? Is there a relationship between foundation strategies and colony success? Is the total number of cells per nest related to the number of adults produced? The study was conducted in Juiz de...

Nidification of Polybia rejecta (Hymenoptera: Vespidae) associated to Azteca chartifex (Hymenoptera: Formicidae) in a fragment of Atlantic Forest, in the state of Minas Gerais, southeastern Brazil Biota Neotropica
Souza,Marcos Magalhães de; Pires,Epifânio Porfiro; Prezoto,Fábio.
Records to nesting between associated social wasp Polybia rejecta(Fabricius, 1798) and the ant Azteca chartifex Forel, 1896 in the Parque Estadual do Rio Doce, Minas Gerais, are reported. This association is reported for the first time in this biome. Twelve colonies of P. rejecta founded close to nests of A. chartifex were observed. The wasp colonies were founded at a distance of about 10-20 cm from the ant nest and they did not overlap. The nests of wasps were smaller compared to ant, but the coloring was similar protective casing, making it difficult to differentiate between the wasp nest and the ant.

Prey captured and used in Polistes versicolor (Olivier) (Hymenoptera: Vespidae) Nourishment Neotropical Entomology
Prezoto,Fábio; Santos-Prezoto,Helba H.; Machado,Vera L.L.; Zanuncio,José C..
The social wasps are predators of many insect species and the study of their preys can reveal the potential of these natural enemies in biological control programs. A total of 240h of collections of preys in 32 nests of Polistes versicolor (Olivier) was carried on in Juiz de Fora, Minas Gerais State, Brazil, from March 2000 to February 2001. The preys captured by P. versicolor were mainly those from the orders Lepidoptera (95.4%) and Coleoptera (1.1%) while 3.4% of them were not identified. Chlosyne lacinia saundersii Doubleday & Hewitson (Lepidoptera: Nymphalidae) was the most collected prey (13.5%). The total of 4,015 preys was estimated to be captured per colony of P. versicolor during one year. The species can be used in integrated pest...

Sexual behavior of the digger wasp Sphex ingens Smith (Hymenoptera, Sphecidae) Rev. Bras. entomol.
Souza,Carlos Alberto S.; Prezoto,Fábio; Lima,Mauro Sérgio C.S.; Pederassi,Jonas.
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...

Survey of preys captured and used by Polybia platycephala (Richards) (Hymenoptera: Vespidae, Epiponini) Neotropical Entomology
Prezoto,Fábio; Lima,Maria A.P.; Machado,Vera L.L..
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...

The ant fauna of hospitals: advancements in public health and research priorities in Brazil Rev. Bras. entomol.
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...
