25. Effects of sex, host-plant deprivation and presence of conspecific immatures on the cannibalistic behavior of wild Ascia monuste orseis (Godart) (Lepidoptera, Pieridae)
Influência do sexo, da privação de plantas hospedeiras e da presença de imaturos coespecíficos no comportamento canibal de Ascia monuste orseis (Godart) (Lepidoptera, Pieridae) selvagens. A curuquerê-da-couve, A. monuste orseis (Lepidoptera, Pieridae), alimenta-se de plantas da família Brassicaceae, mas ingere ovos e larvas coespecíficos, quando disp

26. Sensory response of the egg parasitoid Telenomus podisi to stimuli from the bug Euschistus heros.
The objective of this work was to study the foraging behavior of Telenomus podisi Ashmead (Hymenoptera: Scelionidae) in the presence of stimuli from its host, Euschistus heros (Heteroptera: Pentatomidae). The stimuli selected were: egg mass; virgin males and females; volatile extracts of sexually mature males and females; components of male sex pheromone; a

27. Egg parasitoid wasps as natural enemies of the neotropical stink bug Dichelops melacanthus.
Abstract ? The objective of this work was to determine the potential of five species of Scelionidae wasps ? Telenomus podisi, Trissolcus basalis, Trissolcus urichi, Trissolcus teretis and Trissolcus brochymenae ? as natural enemies of the neotropical stink bug Dichelops melacanthus, and to determine if the presence of eggs of other stink bug species influenc

28. Susceptibility and morbidity between male and female Swiss mice infected with Angiostrongylus costaricensis = Susceptibilidade e morbidade entre camundongos Swiss machos e fêmeas infectados com Angiostrongylus costaricensis / Susceptibilidade e morbidade entre camundongos Swiss machos e fêmeas infectados com Angiostrongylus costaricensis
The gender of vertebrate hosts may affect the outcome of parasitic infections. An experimental murine infection with Angiostrongylus costaricensis was followed with determinations of body weight, fecal larval elimination, number and length of adult worms, number of macroscopic intestinal lesions, and mortality. Groups of male and female Swiss mice were infec

29. Helminths of introduced house sparrows (Passer domesticus) in Brazil : does population age affect parasite richness? / Helmintos de pardais (Passer domesticus) introduzidos no Brasil: a idade da população afeta a riqueza de parasitos?
A introdução de espécies tem alterado a diversidade dos parasitos e seus hospedeiros em todo o mundo. No caso dos hospedeiros introduzidos, a idade da população parece ser um bom preditor da riqueza parasitária. A alteração do habitat é outra variável que pode ter impacto sobre as interações parasito-hospedeiro, pois afeta a disponibilidade de ho

30. Parasitóide de pupas Trichospilus diatraeae (Hymenoptera: Eulophidae): desenvolvimento e reprodução em lepidópteros-praga do dendezeiro / Parasitoid pupae Trichospilus diatraeae (Hymenoptera: Eulophidae): Development and reproduction in defoliating caterpillars of oil palm
The African palm or oil palm (Elaeis guineensis Jacq.) is a plant of African origin and considered the major industrialized activity in humid areas, similar in Amazon area. The expansion of oil palm, especially in northern region of Brazil, has presented more phytosanitary problems, including the caterpillars defoliating Brassolis sophorae L. Opsiphanes invi

31. Comparative reproductive biology of the social parasite Acromyrmex ameliae de Souza, Soares & Della Lucia and of its host Acromyrmex subterraneus subterraneus Forel (Hymenoptera: Formicidae)
Social parasites exhibit several characteristics that allow them to exploit their host species efficiently. The smaller size of parasite species is a trait commonly found in ants. In this work, we investigated several aspects of the reproductive biology of Acromyrmex ameliae De Souza, Soares & Della Lucia, a recently discovered parasite of Acromyrmex subterr

32. Epibionts on Arenaeus cribrarius (Brachyura: Portunidae) from Brazil
Mean prevalence and intensity of infestations by epibionts were evaluated in Arenaeus cribrarius (Lamarck, 1818), based on monthly samplings (May/1991 to April/1993), in Ubatuba, Brazil. Bryozoans were quantified in terms of colony numbers and barnacles by the number of specimens. Prevalence of infestation was determined in 1,914 individuals of A. cribrarius

33. Avaliação das características da motilidade (CASA), morfologia e funcionalidade da membrana plasmática (HOST) de espermatozóides bovinos sexados por cimetria de fluxo / Assesment of Motility Chacarteristics (CASA), morphology; plasmatic membrane funcionality (HOST) in flow citometry sex sorted bovine sperm
Sex selecting has a huge impact in dairy and beef production. The only way commercially viable to obtain sex selecting nowadays, is a flow citometry sex sorted sperm technique. Currently sex sorted sperm have been used regularly in Artificial Insemination programs. Meanwhile, there are limitations about non return rate in farm conditions, superficially expla

34. Does minor histocompatibility antigen HA-1 disparity affect the occurrence of graft-versus-host disease in tunisian recipients of hematopoietic stem cells?
INTRODUCTION: Minor histocompatibility antigen HA-1 (MiHAg-HA-1) disparity between a patient and his or her human leukocyte antigen (HLA) genoidentical donor has been widely associated with an increased risk of graft-versus-host disease following allogeneic hematopoietic stem cell transplantation. OBJECTIVE: To examine the effect of HA-1 disparity on the inc

Esteato-hepatite não alcoólica e esteatose em hepatite crônica pelo vírus C: prevalência e relações entre dados demográficos e clínico-laboratoriais com parâmetros histopatológicos / Nonalcoholic steatohepatitis and steatosis in chronic hepatitis C: prevalence and the relationship between demographic, clinical and laboratory data with histopathological parameters
Chronic hepatitis C is the leading cause of progressive liver damage and related complications, such as cirrhosis and primary hepatocellular carcinoma. Fibrosis stage and necro-inflammatory activity grade are good predictors of disease progression in chronic hepatitis C (CHC).The global epidemic of obesity and diabetes are associated with the increasing inci

36. Ecological parameters of the endohelminths in relation to size and sex of Prochilodus argenteus (Actinopterygii: Prochilodontidae) from the Upper São Francisco River, Minas Gerais, Brazil
This research aimed to investigate the ecological indexes of the helminths of the digestive system and coelom of Prochilodus argenteus Spix & Agassiz, 1829. A total of 150 specimens (53 males and 97 females) taken from the upper reaches of the São Francisco River in the municipality of Três Marias (18º12'32"S, 45º15'41"W), State of Minas Gerais, Brazil,
