Análise das principais espécies de Scolytidae coletadas em floresta primária no estado do Amazonas

Insects of the Subfamily Scolytinae (Insecta: Coleoptera, Curculionidae) Collected with Pitfall and Ethanol Traps in Primary Forests of Central Amazonia

“…The Xyleborus genus stood out from the others because it represented 97% of the collection in the pitfall trap and 57.14% in the EC trap. The predominance of this genus has already been observed in the work carried out also in primary forest by Abreu [14].…”

“…Studies involving biology and ecology of this subfamily have also been conducted in the Amazon, using mainly flight intercept traps, in which an attractive substance is used [13][14][15]. These insects have also been found in other substrates, as shown by surveys conducted by Schubart and Beck [16], Penny and Arias [13], Morais [17,18], and Rodrigues [19], in samples collected from trees, leaf litter and on the ground, Psyche where various types of traps were used, including the pitfall trap.…”

Diversidade de Scolytinae (Coleoptera: Curculionidae) em diferentes paisagens no norte do Brasil

“…According to this author, X. affinis apparently has no preference for hosts and may attack a wide range of plants, including herbs and lianas. The strong dominance of X. affinis can be explained by interspecific competition, considering that fast-growing species are more destructive and reduce the resources available for other plant species (Abreu et al, 1997).…”

Coleópteros broqueadores de madeira em ambiente natural de Mata Atlântica e em plantio de eucalipto

“…O monitoramento de insetos em plantações e sistemas florestais é uma importante ferramenta do manejo integrado de pragas, pois serve para auxiliar na análise de sua flutuação populacional. Armadilhas em que se utiliza o etanol como atrativo são uma boa alternativa para o monitoramento de insetos, principalmente em povoamentos florestais e em especial para os da Ordem Coleoptera (Flechtmann et al, 1996;Abreu et al, 1997;Ferraz et al, 1999;Dorval et al, 2004;Pelentir, 2007;Murari et al, 2012). Isto se deve ao álcool, que atrai as coleobracas de forma similar à madeira, e aos produtos provenientes da fermentação dos extrativos da madeira de árvores recém abatidas ou senescentes (Trevisan et al, 2008).…”
