Bromeliad-inhabiting mosquitoes in an urban botanical garden of dengue endemic ...
Mocellin,Márcio Goulart; Simões,Taynãna César; Nascimento,Teresa Fernandes Silva do; Teixeira,Maria Lucia França; Lounibos,Leon PhilipImmatures of both Aedes aegypti and Aedes albopictus have been found in water-holding bromeliad axils in Brazil. Removal of these plants or their treatment with insecticides in public and private gardens have been undertaken during dengue outbreaks in Brazil despite uncertainty as to their importance as productive habitats for dengue vectors. From March 2005-February 2006, we sampled 120 randomly selected brome...
Control of grapevine wood fungi in commercial nurseries
Oliveira, Helena; Rego, Cecilia; Nascimento, Teresa; Cabral, Ana; Silva, Maria JoséPrevious surveys conducted in commercial nurseries found that different wood fungi, namely Cylindrocarpon spp., Botryosphaeriaceae, Phomopsis viticola and Phaeomoniella chlamydospora infect grapevine cuttings. Two fi eld trials were carried out to evaluate the effectiveness of cyprodinil + fl udioxonil, pyraclostrobin + metiram, fl udioxonil and cyprodinil to prevent or reduce natural infections caused by such ...
Diverse population dynamics of three Anopheles species belonging to the Triannu...
Silva-do-Nascimento,Teresa Fernandes; Lourenço-de-Oliveira,RicardoThe Triannulatus Complex of Anopheles (Nyssorhynchus) consists of at least three sibling species, namely Anopheles triannulatus s.s., Anopheles halophylus and a third undescribed member herein referred to as An. triannulatus "C". Sympatric anophelines belonging to species complexes, even though closely related, may exploit different environments such as larval habitats. In this paper we hypothesize that rainfal...
Obtenção in vitro do teleomorfo de Cylindrocarpon destructans, Neonectria Radic...
Oliveira, Helena; Rego, Cecilia; Cabral, A.; Nascimento, TeresaBlack-foot is an important grapevine disease, caused by the fungus Cylindrocarpon destructans, which causes a darkening of the basal-end of the plant, leading to early decline and death of young grapevines. Both, C. destructans and C. obtusisporum are considered responsible for this disease, although only the former was isolated in Portugal. Neonectria radicicola (teleomorph of C. destructans) is an Ascomycota ...
Anopheles halophylus, a new species of the subgenus Nyssorhynchus (Diptera: Cul...
Nascimento,Teresa Fernandes Silva do; Lourenço-de-Oliveira,RicardoAnopheles halophylus n.sp. is described from Central Brazil. It is distinguished from An. triannulatus (Neiva and Pinto) by morphological and morphometric characters, especially in the male genitalia, larva and egg. Illustrations of the male and female genitalia, egg, larva and pupa, and discussion of the status of names associated with An. triannulatus are provided.
