Does body size of neotropical ant species influence their recruitment speed? Biota Neotropica
Godoy,Bruno Spacek; Camargos,Lucas Marques de.
Ants are one of the most important animal groups in tropical forests because of its abundance and number of species. An important characteristic of the group is the eusociality, which allows the occurrence of a recruitment behavior when food resource is found. However, there are two main questions regarding this behavior: (i) the recruitment is a product of environmental or phylogenetic pressures, and (ii) the recruitment speed is related to the body size of the ant species. In this work we addressed these two questions using 17 species of neotropical ants, in the Amazonic lowland dense rain forest. According to results, recruitment behavior is related to ant size, where smaller species exhibit this trait when finding a protein resource. However, species...

Dynamics of the restoration of physical trails in the grass-cutting ant Atta capiguara (Hymenoptera, Formicidae) Rev. Bras. entomol.
Caldato,Nadia; Forti,Luiz Carlos; Camargo,Roberto da Silva; Lopes,Juliane Floriano Santos; Fourcassié,Vincent.
ABSTRACT Dynamics of the restoration of physical trails in the grass-cutting ant Atta capiguara. Leaf-cutting ants of the genus Atta build long physical trails by cutting the vegetation growing on the soil surface and removing the small objects they find across their path. Little is known on the dynamics of trail construction in these ants. How much time do they need to build a trail? To answer this question we selected six trails belonging to two different nests of A. capiguara and removed on each trail a block of soil of 20 cm × 15 cm that included a portion of the physical trail. This block was then replaced by a new block of the same size that was removed in the pasture near the trail and that was uniformly covered by the same type of vegetation as...

Firewood as a pathway for insect introductions: What are the risks of ant invasions in Patagonia? Ecología austral
Werenkrut,Victoria; Pirk,Gabriela I; Lescano,María N; Benclowicz,José D; Elizalde,Luciana.
Firewood can act as a long-distance dispersal vector for wood-infesting insects both within and among countries. Recently, we detected the alien carpenter ant Camponotus mus in firewood transported from central Argentina to Patagonia. This species generates significant economic losses in its native range and has invader potential. Moreover, global warming and the increasing anthropogenic disturbance in Patagonian ecosystems make them highly susceptible to insect invasions. This is especially alarming considering the current lack of sanitary controls of incoming goods into the region. To prevent insect introductions via firewood, it is crucial to implement a joint efort among the scientific community, control organisms, government and end user.

Hymenoptera marking technique J. Venom. Anim. Toxins incl. Trop. Dis.
Pereira,A. M.; Chaud-Netto,J..
In true social hymenopterans, such as many species of bees, wasps and all species of ants, the main characteristics are the overlapping of generations, the care with the offspring and the division of labor among the members of the colony. The first biological feature means that in a same moment there are groups of individuals, with variable ages, that execute different activities in the colony. In order to study the division of labor among the members of the colony, or to estimate the life span of these insects, or even to analyze any kind of behavior in non-social insects, it is necessary to know the exact age of each individual. For this reason, the insects must be identified soon after emergence. The identification of insects with numbers is an...

Nest architecture development of grass-cutting ants Rev. Bras. entomol.
Forti,Luiz Carlos; Moreira,Aldenise Alves; Camargo,Roberto da Silva; Caldato,Nadia; Castellani,Maria Aparecida.
ABSTRACT Atta bisphaerica is a species of grass-cutting ants commonly found in the Cerrado biome. The Brazilian Cerrado (savanna) biome covers 2 million km representing 23% of the area of the country. It is an ancient biome with rich biodiversity, estimated at 160,000 species of plants, fungi and animals. However, little is known about their nest architecture development. This study investigated the architecture of fourteen A. bisphaerica nests from Botucatu, São Paulo, Brazil. Molds were made of the nests by filling them with cement to allow better visualization of internal structures such as chambers and tunnels. After excavation, the depth and dimensions (length, width, and height) of the chambers were measured. As expected, there was a lateral...

Souza, Marcos Magalhaes de; Universidade Federal de Lavras; Pires, Epifânio Porfiro; Universidade Federal de Lavras; Elpino-Campos, Abner; Universidade Federal do Rio Grande do Sul; Louzada, Júlio Neil Cassa; Universidade Federal de Lavras.
The survival of social wasp species depends on the success in founding new nests. These species can use plant species with different specific characteristics for nesting, with nest architecture varying according to the habits of those plant species. The nesting of social wasps in natural environments was studied in the period from October 2005 to September 2007 inthe rio das Mortes riparian forest, municipal district of Barroso, Minas Gerais State, Brazil, with the objective of evaluating the different types of plant substrate used by social wasps for nesting, and to investigate whether there is a relationship between nest construction type and the habits of plant species. A total of 171 colonies of social wasps belonging to 29 species were recorded, which...

New host association: Polybia scutellaris (Hymenoptera, Vespidae) parasitized by Melaloncha (Diptera, Phoridae) Rev. Bras. entomol.
Lutz,M. Ayelen; Brown,Brian V..
New host association: Polybia scutellaris (Hymenoptera, Vespidae) parasitized by Melaloncha (Diptera, Phoridae). The genus Melaloncha Brues is a large assemblage of New World, parasitoid phorid flies. They are parasitoids of Apoidea bees. However, here we present the first record of a wasp parasitized by Melaloncha sp. The new host is Polybia scutellaris (White), a neotropical eusocial wasp. The parasitized wasp was found in an urban park near the city of La Plata, Buenos Aires, Argentina. It appears that the genus Melaloncha parasitizes a wider range of social Hymenoptera than currently known.

Notes on the diet of seven terrestrial frogs in three agroecosystems and forest remnants in Northwestern São Paulo State, Brazil. Repositório Alice
MENIN, M.; SANTOS, R. S.; BORGES, R. E.; PIATTI, L..
Anurans are predators of a great diversity of invertebrates, but studies on agroecosystems are very scarce. Herein we described the diet composition of seven species of terrestrial anurans captured in three different agroecosystems (corn, soybean and rubber tree) and in forest remnants of the Northwestern region of São Paulo state, Brazil. Ten prey categories were identified in the stomachs of 80 specimens belonging to the families Bufonidae, Leptodactylidae and Microhylidae. Hymenoptera (Formicidae) was consumed by all species. Coleoptera was the most frequent item, consumed by six of the even species followed by Araneae and Isoptera. Isoptera was the most abundant item followed by Formicidae, Coleoptera and Araneae. Adults and juveniles of Physalaemus...

Record of foraging of ants (Hymenoptera, Formicidae) in vertebrate carcasses Biological Sciences
Maciel, Tatiane Tagliatti; Barbosa, Bruno Corrêa; Santos-Prezoto, Helba Helena; Prezoto, Fábio.
 Knowing the importance of participation by insects at cadaverous decomposition processes, and the limited use of the family Formicidae in criminal investigations, this study aims to record the foraging activity of four genera of ants in carcasses of birds and mammals. Observations occurred accidentally in two locations in the State of Minas Gerais, Brazil. In total, seven species of ants foraging in eight vertebrate carcasses were recorded. In addition, the study reported for the first time the presence of Wasmannia in carcasses in Brazil.

The mitochondrial genome of the stingless bee Melipona bicolor (Hymenoptera, Apidae, Meliponini): sequence, gene organization and a unique tRNA translocation event conserved across the tribe Meliponini Genet. Mol. Biol.
Silvestre,Daniela; Dowton,Mark; Arias,Maria Cristina.
At present a complete mtDNA sequence has been reported for only two hymenopterans, the Old World honey bee, Apis mellifera and the sawfly Perga condei. Among the bee group, the tribe Meliponini (stingless bees) has some distinction due to its Pantropical distribution, great number of species and large importance as main pollinators in several ecosystems, including the Brazilian rain forest. However few molecular studies have been conducted on this group of bees and few sequence data from mitochondrial genomes have been described. In this project, we PCR amplified and sequenced 78% of the mitochondrial genome of the stingless bee Melipona bicolor (Apidae, Meliponini). The sequenced region contains all of the 13 mitochondrial protein-coding genes, 18 of 22...

The social wasp Polybia fastidiosuscula Saussure (Hymenoptera: Vespidae) uses herbivore-induced maize plant volatiles to locate its prey. Repositório Alice
SARAIVA, N. B.; PREZOTO, F.; FONSECA, M. das G.; MORAES, M. C. B.; BORGES, M.; LAUMANN, R. A.; AUAD, A. M..
Social wasps in the Polybia genus are important for use as pest-control agents in agricultural systems. The objective of this study was to investigate the behavioural responses of Polybia fastidiosuscula Saussure (Hymenoptera: Vespidae) to volatiles from maize, both constitutive volatiles and those induced by the herbivory of Spodoptera frugiperda (JE Smith) (Lepidoptera: Noctuidae). To assess the behavioural response of P. fastidiosuscula to S. frugiperda larvae, undamaged plants, S. frugiperda-damaged plants, mechanically damaged plants, mechanically damaged plants plus regurgitant from larvae and extracts from various treatments, bioassays were conducted in a Y-olfactometer. In addition, the volatiles from plants subjected to different treatments were...

Varroa destructor in Juquitiba, Vale do Ribeira, Southeastern Brazil: Seasonal Effects on the Infestation Rate of Ectoparasitic Mites on Honeybees Ciências Agrárias
Pinto, Fábio de Assis; Puker, Anderson; Message, Dejair; Barreto, Lídia Maria Ruv Carelli.
We evaluated the infestation rate (IR) of the ectoparasite mite Varroa destructor in hives of the Africanized honeybee Apis mellifera in 10 commercial apiaries located in the municipality of Juquitiba (Vale do Ribeira, São Paulo, Brazil) during two seasons (summer and winter). From each apiary, three colonies were randomly selected for collection of bee samples in each season. The average mite IR was 7.3%, when pooling both seasons. For the summer period the average IR varied from 1.1 to 11.6% (KW = 25.9191; p < 0.01). For the winter period, IR values were observed ranging from 0.3 to 19.1% (KW = 18.7760; p < 0.05). In only three of the studied apiaries did the IR remain unchanged over both seasons, even though it tended to be higher during the...
