3. Ação de cordia verbenacea sobre schistosoma mansoni / Activity of cordia verbenacea on schistosoma mandoni
The trematode Schistosoma mansoni is responsible for causing a form of schistosomiasis that kills around 280,000 people each year. Since there are cases of tolerance and resistance to the drugs currently used in the treatment for this disease, namely praziquantel (PZQ) and oxamniquine, there is a need for new schistosomicidal drugs. In that regard, the resea

4. Canaania obesa (Platyhelminthes: Dicrocoeliidae): redescription and new hosts records
The digenetic trematode Canaania obesa Travassos, 1944 (Dicrocoeliidae) was described as a parasite of the bile ducts of the rodent Akodon cursor Winge, 1887 (Cricetidae) collected in Santa Teresa, state of Espírito Santo, Brazil. In the present study, we report the occurrence of C. obesa infecting three additional sigmodontinae rodent species: Akodon monte

5. Aspectos biológicos e morfologia externa dos imaturos de Memphismoruus stheno (Prittwitz) (Lepidoptera: Nymphalidae)
Immature stages of Memphis moruus stheno (Prittwittz) were subject of a behavior, biological and morphological study. The morphological study was carried out through observation by stereoscopic microscopy with camera lucida and micrometric lens attached for illustrations and measurements, respectively; and scanning electron microscopy for ultrastructural ana

6. Análisis morfológico de huevos de Triatoma barberi Usinger(Hemiptera: Reduviidae)
Triatoma barberi Usinger is a widely recognized vector of the protozoa Trypanosoma cruzi. The determination of its presence in the rural houses is made by direct observation of adults, nymphs, exuviae or eggs. For this reason, egg structural characteristics could facilitate the differentiation and identification of species that inhabit such environments. In

7. Spinitectus osorioi (Nematoda: Cystidicolidae) in the Mexican endemic fish Atherinella alvarezi (Atherinopsidae) from the Atlantic River drainage system in Chiapas, Southern Mexico
Specimens of Spinitectus osorioi Choudhury and Pérez-Ponce de León, an intestinal nematode species previously considered to be specific to Chirostoma spp and endemic to some lakes in the Pacific drainage in Michoacán, were collected from the freshwater fish Atherinella alvarezi (Díaz-Pardo) (Atherinopsidae) of the Michol River near Palenque, Chiapas, Sou

8. Morphological study of the eggs and nymphs of triatoma dimidiata (Latreille, 1811) observed by light and scanning electron microscopy (Hemiptera: Reduviidae: Triatominae)
Eggs and nymphs of Triatoma dimidiata were described using both light and scanning electron microscopy. The egg body and operculum have an exochorion formed by irregular juxtaposed polygonal cells; these cells are without sculpture and the majority of them are hexagonal in shape. The five instars of T. dimidiata can be distinguished from each other by charac

9. Seletividade de fungos entomopatogênicos a Trichogramma pretiosum Riley (Hymenoptera: trichogrammatidae) e virulência a Bemisia tabaci (Hemiptera: Aleyrodidae
The entomopathogenic fungi and the parasitoid Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) can be used, at the same time, in the tomato culture. However, it is still unclear the effects of entomopathogenic fungi on T. pretiosum. Thus, this study aimed to analyze the selectivity of entomopathogenic fungi against T. pretiosum and assess the vi

11. Comparative descriptions of eggs from three species of Rhodnius (Hemiptera: Reduviidae: Triatominae)
The authors describe and compare the morphological and ultrastructural characteristics of eggs from the three most recent described species of the genus Rhodnius Stål, 1859, which have not previously been studied. These species are Rhodnius colombiensis (Mejia, Galvão & Jurberg 1999), Rhodnius milesi (Carcavallo, Rocha, Galvão & Jurberg 2001) and Rhodnius

12. 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
