RESUMO
ABSTRACT Pineus boerneri Annand, 1928 (Hemiptera: Adelgidae), a new exotic aphid species, was found in 2002 and 2004 infesting Pinus plantations in the states of São Paulo and Minas Gerais, Brazil. This is the first report of this species and family in pine plantations in the Brazilian Southeast. The geographic distribution, symptoms and damage caused by this species are presented.
RESUMO Uma nova espécie exótica de pulgão, Pineus boerneri Annand, 1928 (Hemiptera: Adelgidae) foi encontrada em 2002 e 2004 infestando plantios de Pinus, nos Estados de São Paulo e Minas Gerais, sendo este o primeiro relato tanto da espécie quanto da família destes pulgões em plantios dePinus spp. na região Sudeste do Brasil.

RESUMO
Rabies in wild canids in Northeastern Brazil is frequent and has been reported for some time, with episodes of rabies transmission from these animals to humans also reported. In this study, we analyzed the antigenic and genetic profiles of the rabies virus nucleoprotein gene, isolated from 20 samples taken from domestic animals and wild canids located in the Northeastern region of Brazil. All viruses isolated from domestic animals (dogs and cats) belonged to the antigenic variant 2 (AgV2). Among the wild animal samples, only four were AgV2, and nine showed a divergent antigenic profile. Phylogenetic analysis revealed two Brazilian clusters. Cluster 1 (Brazilian domestic carnivore-related strains) showed two subclusters, called 1A and 1B, and cluster 2 (Brazilian wild canid-related strains) also showed two subclusters, called 2A and 2B. The majority of the samples with divergent antigenic strains segregated into subcluster 2A. The intracluster identity of cluster 1 was 95.6% and that of cluster 2, 92.4%. When clusters 1 and 2 were compared, an identity of 88.6% was found. The genetic analysis of wild canid samples performed in this study indicates that there are two distinct rabies cycles among canids in Brazil, one represented by domestic canids and the other by wild canids. This study shows that the virus samples isolated in Northeastern Brazil are region and species-specific.
