1. Identification of two species of Binema Travassos 1925 (Oxyurida: Travassosinematidae) and Cameronia arecoensis Marchissio and Miralles 1987 (Oxyurida: Thelastomatidae) based on morphological and 18S rRNA partial sequence
Abstract: Oxyurid nematodes parasitizing the mole cricket Neoscapteriscus vicinus were isolated in the framework of sampling fields of mole-crickets from the pampean region, in Argentina. In this work, molecular characterization of the 18S rRNA partial sequence of nematodes belonging to the families Thelastomatidae (Cameronia arecoensis Marchissio and Mirall

2. Identification, expression and characterization of the recombinant Sol g 4.1 protein from the venom of the tropical fire ant Solenopsis geminata
Abstract Background: Fire ant venom is a complex mixture consisting of basic piperidine alkaloids, various biologically active peptides and protein components, including a variety of major allergenic proteins. Tropical fire ant Solenopsis geminata is an important stinging ant species that causes anaphylaxis and serious medical problems. Although the biologi

3. Hemolytic, anticancer and antigiardial activity of Palythoa caribaeorum venom
Abstract Background Cnidarian venoms and extracts have shown a broad variety of biological activities including cytotoxic, antibacterial and antitumoral effects. Most of these studied extracts were obtained from sea anemones or jellyfish. The present study aimed to determine the toxic activity and assess the antitumor and antiparasitic potential of Palythoa

4. Composition and biological activities of the aqueous extracts of three scleractinian corals from the Mexican Caribbean: Pseudodiploria strigosa, Porites astreoides and Siderastrea siderea
Abstract Background: Scleractinian corals (stony corals) are the most abundant reef-forming cnidarians found in coral reefs throughout the world. Despite their abundance and ecological importance, information about the diversity of their toxins and their biological activities is very scarce. In this study, the chemical composition and the biological activit

5. Pharmacological characterization of venoms from three theraphosid spiders: Poecilotheria regalis, Ceratogyrus darlingi and Brachypelma epicureanum
Abstract Background Tarantulas (Theraphosidae) represent an important source of novel biologically active compounds that target a variety of ion channels and cell receptors in both insects and mammals. In this study, we evaluate and compare the pharmacological activity of venoms from three taxonomically different theraphos

6. Natural history of Micrablepharus maximiliani (Squamata: Gymnophthalmidae) in a Cerrado region of northeastern Brazil
Micrablepharus maximiliani (Reinhardt & Luetken, 1861) is a microteiid lizard widely distributed in the open areas of South America. Little is known about its ecology and reproductive biology. Here, we analyzed aspects of the natural history of a population of M. maximiliani from a Cerrado area in the state of Piauí, northeastern Brazil. Our results suggest

7. First experimental evidence that a harvestman (Arachnida: Opiliones) detects odors of non-rotten dead prey by olfaction
Harvestmen feed on live, dead and fresh, or decomposing animals, fungi, and plant matter, being very dependent on chemoreception to find food. Herein we performed an experiment to test if individuals of Discocyrtus pectinifemur Mello-Leitão, 1937 (Gonyleptidae) (n = 23) behave differently when in contact with olfactory cues from different sources (rotten pr

8. Characterization of the allergen Sol gem 2 from the fire ant venom, Solenopsis geminata
Sol i 2 is a potent allergen in Solenopsis invicta venom, and most humans exhibit reactivity to it. The Sol gem 2 allergen found in the venom of the Thai tropical fire ant Solenopsis geminata was analysed in the present study. The protein was present in higher amounts than other proteins, as determined by SDS-PAGE, and presumably has allergenic properties si

9. Female monopolization and paternity assurance in South American crickets (Orthoptera, Grylloidea): mating plugs, extra claspers and forced copulation
Este trabalho descreve os primeiros três casos em que grilos machos monopolizam suas fêmeas através de plugues de acasalamento. A origem dessas estruturas varia entre os casos (i.e., não há homologia entre as mesmas). A monogamia feminina é assegurada pela presença permanente do plugue de acasalamento aderido a sua genitália após a primeira cópula,

10. ARTRÓPODES CAVERNÍCOLAS COM ÊNFASE EM FLEBOTOMÍNEOS (DIPTERA: PSYCHODIDAE) DO MUNICÍPIO DE PRESIDENTE FIGUEIREDO, AMAZONAS, BRASIL.
The cave fauna of the Brazilian State of Amazonas is poorly documented, publications being mainly restricted to summaries in congress reports. In this study three cavities in paleozoic sandstones formations in the municipality of Presidente Figueiredo, approximately 110 km north of the lower Rio Negro at Manaus, were sampled for arthropods. The techniques us

11. Phalangopsidae crickets (Orthoptera: Grylloidea) in Viçosa, Minas Gerais, Brasil / Os grilos Phalangopsidae (Orthoptera: Grylloidea) em Viçosa, Minas Gerais, Brasil
Os grilos Phalangopsidae (Orthoptera: Ensifera: Grylloidea) são facilmente coletados, criados e manipulados devido ao tamanho relativamente grande do corpo e pela abundância nas regiões tropicais. Entretanto, estudos taxonômicos, sistemáticos e biológicos são escassos para a maioria dos grupos neotropicais. Por isso este trabalho visou organizar o con

12. Invertebrados de cavernas do Distrito Federal: diversidade, distribuição temporal e espacial
There are 4,153 registered caves in Brazil, but most cave studies has been done by observant cavers rather than part of surveying programs. A correlate problem is the lack of ertebrates were sampled by active seach (hand collecting and the register of rganisms) and by baited pitfall traps. The number of traps varied among caves due to their morphological and
