Preferência de vôo de nove espécies da família scolytidae (Insecta: Coleoptera) na Amazônia Central1

Abstract

RESUMO -Neste trabalho foi avaliada a preferência por altura de vôo de nove espécies da família Scolytidae, capturadas com armadilhas Escolitídeo/Curitiba e Marques/Carrano/Abreu, instaladas a 1; 3; 5; 7,5 e 10m de altura na Reserva Florestal Adolpho Ducke, no km 22 da rodovia AM-010 (Manaus, AM). Para isto foi feita uma análise de variância e as médias comparadas pelo teste de Tukey. O resultado das análises mostraram que, independente da armadilha utilizada, Xyleborus affinis Eichhoff, Xyleborus sp. 1 e Monarthrum sp. 1 apresentaram preferência de vôo por alturas inferiores a 3m; Cryptocarenus heveae (Hagedorn) mostrou preferência por alturas superiores a 5m; e Hypothenemus obscurus Fabricius acima de 7,5m; Xylosandrus compactus Eichhoff não apresentou preferência por qualquer altura de vôo. Cryptocarenus diadematus Eggers, Hypothenemus eruditus Westwood e Premnobius cavipennis Eichhoff apresentaram divergência quanto à tendência de vôo, em relação às armadilhas utilizadas.

These insects were captured with Escolitídeo/Curitiba and Marques/Carrano/Abreu traps, installed at heights of 1, 3, 5, 7,5, and 10m, in the Adolpho Ducke forest reserve, located at the km 22 of AM-10 road (Manaus, AM). An analysis of variance was carried out and the means were separated by the Tukey test. The results showed that, in both traps, the Xyleborus affinis Eichhoff species, Xyleborus sp.1 and Monarthrum sp.1, had preference for heights below 3m; Cryptocarenus heveae (Hagedorn) for heights above 5m, and Hypothenemus obscurus the other hand, Hypothenemus eruditus Westwood, Cryptocarenus diadematus Eggers, and Premnobius cavipennis Eichhoff presented discrepancy concerning flight preference,

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

“…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.…”
