Zusammenfassung: | The red gum lerp psyllid, Glycaspis brimblecombei Moore, 1964 (Hemiptera: Aphalaridae), an insect pest originating in Australia and which feeds only on Eucalyptus L'Her. (Myrtales: Myrtaceae) plants, has spread to several countries. The populations of this insect commonly reach high populations on Eucalyptus plants since its entry into Brazil, and also indicated an unrecorded behavioral. The objectives of this study were to describe a peculiar adaptation in the feeding habit of G. brimblecombei and to register the new habit. The oviposition and feeding by G. brimblecombei, commonly, on the leaves of Eucalyptus, started to occur, also, on lignified twigs. This suggests a not yet recorded adaptation of this insect to reduce insect x plant intraspecific competition. Keywords: intraspecific competition, insect behavior, Eucalyptus camaldulensis, eucalypt pest, red gum lerp psyllid. O psilideo de concha, Glycaspis brimblecombei Moore, 1964 (Hemiptera: Aphalaridae), um inseto praga originario da Australia e que se alimenta apenas de plantas de Eucalyptus L'Her. (Myrtales: Myrtaceae), se espalhou por varios paises. Esse inseto, geralmente, atinge grandes populacoes em plantas de Eucalyptus desde sua entrada no Brasil e, tambem, indicou um comportamento diferente. Os objetivos deste estudo foram descrever uma adaptacao peculiar no habito alimentar de G. brimblecombei e registrar o novo habito. A oviposicao e alimentacao por G. brimblecombei, geralmente, nas folhas de Eucalyptus, passaram a ocorrer, tambem, em ramos lignificados. Isso sugere uma adaptacao diferente desse inseto para reduzir a competicao intraespecifica inseto * planta. Palavras-chave: competicao intraespecifica, comportamento dos insetos, Eucalyptus camaldulensis, praga do eucalipto, psilideo de concha. |
