American cutaneous leishmaniasis in dogs from an endemic urban area in Cianorte municipality, Paraná State, Brazil J. Venom. Anim. Toxins incl. Trop. Dis.
Cerino,DA; Veloso,J; Perles,TF; Zanzarini,PD; Lonardoni,MVC; Silveira,TGV.
American cutaneous leishmaniasis (ACL) was investigated in dogs from an urban endemic area in Cianorte, Paraná state, Brazil. Of 169 studied dogs, none presented suspected ACL lesions. Eleven animals (6.6%) had anti-Leishmania braziliensis antibodies (titers > 40) detected by the immunofluorescent antibody test (IFAT) while four (2.4%) showed L. braziliensis-complex DNA by the polymerase chain reaction (PCR). Although no associations were found between IFAT or PCR results and age, sex, origin, free-roaming animals or length of residence at the address, the majority of IFAT- or PCR-positive dogs were from the urban area of the city and were allowed to roam freely beyond their neighborhood. The presence of anti-Leishmania braziliensis antibodies and L....

Population dynamics of the invasive species Zaprionus indianus (Gupta) (Diptera: Drosophilidae) in communities of drosophilids of Porto Alegre City, Southern of Brazil Neotropical Entomology
Silva,Norma M. da; Fantinel,Carina da C.; Valente,Vera L.S.; Valiati,Victor H..
Population studies of invasive species allow us to understand how invaders react to new biotic and abiotic conditions, and how native species react to invasion. We evaluated the colonisation efficiency of the invader Zaprionus indianus (Gupta), in the urban area of Porto Alegre city, southern of Brazil. Samples of flies were taken from three urban parks, and ecological indexes were used based on the frequency of the sampled species. The indexes were calculated for breeding and feeding sites separately. The highest frequencies of Z. indianus compared to the other drosophilids were registered during seasons of highest mean temperatures, both for the feeding and the breeding sites. The highest values for the dominance index (D) and the lowest values for...

Twigs of Albizia niopoides (Spruce ex Benth.) Burkart as a nesting resource for ants (Hymenoptera: Formicidae) Rev. Bras. entomol.
Silva,Otávio Guilherme Morais da; Fernandes,Tae Tanaami; Silva,Rogério Rosa da; Souza-Campana,Débora Rodrigues de; Morini,Maria Santina de Castro.
ABSTRACT Ants can use twigs from fragments of tree branches as a nesting resource. The present study analyzed gatherings of ants in twigs of Albizia niopoides, a Fabaceae native to the Atlantic Forest that is used in landscaping in parks and squares in Brazil. Expeditions were performed in an urban park located in Atlantic Forest areas between February and June 2014. A total of 70 twigs with ants were collected and included 9357 workers, 2309 broods ants, 68 winged ants and 19 queens. Four subfamilies, 10 genera and 17 species/morphospecies were recorded. The species with the largest number of nests were Nylanderia sp.1, Hypoponera sp.4, and Wasmannia auropunctata. Ants of different species were found coexisting in the same twig, and Pheidole gr. tristis...
