13. Caracterização morfológica e molecular de híbridos do cruzamento entre Triatoma maculata (Erichson, 1848) e Triatoma pseudomaculata Corrêa &Espínola, 1964 (Hemiptera: Reduviidae). / Morphologic and molecular characterization of hybrids from the cross breeding among Triatoma maculata (Erichson, 1848) and Triatoma pseudomaculata Corrêa &Espínola, 1964 (Hemiptera: Reduviidae)
Due to its great morphological similarities, Triatoma maculata and Triatoma pseudomaculata, classified by Carcavallo et al. (2002) in the maculata complex, were considered the same species until 1964 (Corrêa e Espínola, 1964). These species are alopatric and, according to Schofield (1988), T. maculata would be introduced in the brazilian Northeastern by mi

15. Action of Metarhizium anisopliae (Metschnikoff, 1879) Sorokin, 1883 and Beauveria bassiana (Balsamo) Vuilllemin, 1912 on Ctenocephalides felis felis (Boúche, 1835) (Siphonaptera: Pulicidae) / Ação de Metarhizium anisopliae (Metschnikoff, 1879) Sorokin, 1883 e Beauveria bassiana (Balsamo) Vuilllemin, 1912 sobre Ctenocephalides felis felis (Boúche, 1835) (Siphonaptera: Pulicidae).
Fleas are ectoparasites commonly found in dogs and cats and the species Ctenocephalides felis (Bouché, 1835) are the most found in these animals. Ctenocephalides felis felis life cycle is influenced by temperature and humidity. This haematophagous insect feeds for approximately 30 days; its bite can cause allergic dermatitis and also can transmit several et

16. Crises cambiais x fundamentos macroeconomicos : a experiencia brasileira sob o regime de cambio flutuante (1999-2002)
This work analyzes, from an alternative not-conventional approach (heterodox), the exchange rate crises in the emerging market economies, during the 1990s, and the Brazilian exchange rate crises of 2001 and 2002. In contraposition to the currency crises models developed in the 1980s and 1990s, it discards the deterministic character of the economic fundament

17. AÃÃo de Metarhizium anisopliae var. anisopliae, Metarhizium anisopliae var. acridum, Beauveria bassiana e parÃmetros biolÃgicos apÃs passagem em Rhipicephalus sanguineus
The ticks are important vectors of diseases in the tropical and subtropical areas. Rhipicephalus sanguineus is an ixodÃdeo wich cause severe spoliation in the canÃdeos and is a vector of diseases as the hematozooses (Babesia canis; Ehrlichia canis). This work evaluated the action of Metarhizium anisopliae var. anisopliae, Metarhizium anisopliae var. acridu

18. Otimização da taxa de fertilização e eclosão de larvas de tambaqui, Colossoma macropomum (Cuvier, 1816) abolindo instrumentos.
A reprodução induzida de peixes é uma técnica dominada. No entanto, é possível que alguns procedimentos utilizados atualmente possam prejudicar a produção final de larvas. Assim, a utilização de instrumentos (penas de aves,espátulas) para mistura dos gametas, poderia ser um fator de redução da produção. Este trabalho teve como objetivo testar

19. Temperature influence on embryonic development of Anopheles albitarsis and Anopheles aquasalis
Temperature influence on the embryonic development of Anopheles aquasalis and An. albitarsis was investigated. At 26ºC, 75% and 60% of respectively An. aquasalis and An. albitarsis eggs hatched, with one peak of eclosion, between the 2nd and 3rd day after oviposition. At 20 ± 2ºC, around 66-70% of An. aquasalis eggs hatched, with one eclosion peak, on the

20. Estudo quÃmico e de atividade biolÃgica da Spigelia flemmingiana
Brazil presents a wide variety of superior plants, which have not been yet studied. Among these plants, we may find Spigellia flemmingiana, from the family Loganeaceae, which is currently utilized for anti-helmintic treatment. In the present work, the chemical constituents, antimicrobial and anti-helmintic activities were studied using the crude extracts pre

21. Estudo do crescimento e da reprodução de Bradybaena similaris (Férussac) (Mollusca, Xanthonychidae) em laboratório
Biological aspects of Bradybaena similaris (Férussac, 1821) were studied, such as: onset of sexual maturity, occurrence of self-fertilization, oviposition, incubation period, eclosion rate and shell length measurement at different stages of development. It was noted that in isolated B. similaris the minimum and maximum time for reaching sexual maturity were

22. Experimental evidence for a demographic cline in Panstrongylus megistus populations
The population biology of three populations of Panstrongylus megistus was compared to determine possible influence on the behaviour and epidemiological importance of this species. The results demonstrated differences in terms of egg eclosion time, nymphal mortality and development rates, and feeding and defaecation rates. These differences appeared to follow

23. Oviposition and eclosion periods of Ixodes didelphidis Fonseca and Aragão, 1951 (Acari: Ixodidae) under laboratory conditions
Oviposition and eclosion periods for Ixodes didelphidis were observed under two temperatures (25ºC and 27ºC) and 90-95% humidity. Although there was a significant increase in the eclosion period (p<0.05) and a tendency to increase the oviposition period at 25ºC, there was neither significant differences in the interval (days), until maximum peak of eclosi

24. Rearing of Lymnaea columella (Say, 1817), intermediate host of Fasciola hepatica (Linnaeus, 1758)
The intermediate host of Fasciola hepatica, Lymnaea columella, collected in Belo Horizonte, Minas Gerais, Brazil, was reared in our laboratory. The aim of the current study was to standardize a rearing and maintenance technique. Two kinds of diet were tested: fresh lettuce (A) and rodent ration + 10% CaCO3 plus fresh lettuce (B). The age for the beginning of
