Assemblages of endophagous insects on Asteraceae in São Paulo Cerrados
Provedor de dados: 82
Autores: Almeida,Adriana M.; Fonseca,Carlos R.; Prado,Paulo I.; Almeida-Neto,Mário; Diniz,Soraia; Kubota,Umberto; Braun,Marina R.; Raimundo,Rafael L.G.; Anjos,Luciano A.; Mendonça,Tehra G.; Futada,Silvia M.; Lewinsohn,Thomas M.
A survey of the endophagous insects fauna associated to Asteraceae capitula was carried out from 2000 to 2002 in eight cerrado sensu stricto sites located in the Brazilian state of São Paulo. Sixty-four endophagous species of Diptera and Lepidoptera were recorded from 49 asteracean host plants. Approximately half of the species were obtained from a single locality, with a large proportion emerging from a single sample (unicates). Thirty percent of the species were singletons (i.e. only one individual was recorded). The large proportion of rare species suggests a high species turnover among localities. Lepidopteran species were recorded on more host species than dipterans, confirming their more polyphagous food habit, also observed in other Brazilian biomes...

New host-plant records for neotropical agromyzids (Diptera: Agromyzidae) from Asteraceae flower heads
Provedor de dados: 82
Autores: Braun,Marina R.; Almeida-Neto,Mário; Loyola,Rafael D.; Prado,Angelo P.; Lewinsohn,Thomas M.
Agromyzidae is a large and cosmopolitan fly family with approximately 2,500 known species. Here we present 22 new records of agromyzid-host plant associations. Plants were sampled from 2002 to 2005 in São Paulo state, Brazil. A total of eight agromyzid species were reared from 18 Asteraceae host species. The genus Melanagromyza Hendel was the commonest. This is the first detailed study reporting associations between non-leafmining Agromyzidae and their host plants in Brazil.

Erigeron bonariensis: hospedeira alternativa do Lettuce mosaic virus no Brasil
Provedor de dados: 102
Autores: Chaves,Alexandre L. R.; Braun,Marina R.; Eiras,Marcelo; Colariccio,Addolorata; Galleti,Silvia R.
O gênero Erigeron (Asteraceae), de plantas da vegetação espontânea, encontra-se amplamente disseminado nas regiões Sul e Sudeste do Brasil, sendo freqüentemente encontrado em lavouras perenes e anuais. Plantas de E. bonariensis com sintoma de mosaico, típico do induzido por vírus, foram coletadas no município de São Paulo e submetidas a análises ao microscópio eletrônico de transmissão, testes biológicos, sorológicos e moleculares. Em cortes ultrafinos do tecido foliar original, observaram-se inclusões tubulares e cata-ventos dispersos no citoplasma. Através de inoculação mecânica, somente Chenopodium amaranticolor, C. quinoa, Nicotiana benthamiana e N. clevelandii foram infetadas. Os resultados obtidos em ELISA foram negativos quando se utilizaram...
