Resumo

A busca por novos métodos de manejo e controle de formigas-cortadeiras vem sendo enfoque de inúmeros estudos pelo país, impulsionada por aspectos econômicos e ambientais. O estabelecimento de espécies resistentes ou menos preferidas ao corte pode contribuir substancialmente neste sentido. Logo, o objetivo deste estudo foi avaliar a preferência de corte entre as espécies Corymbia citriodora check for this species in other resources , Eucalyptus benthamii check for this species in other resources , Eucalyptus camaldulensis check for this species in other resources , Eucalyptus dunnii check for this species in other resources , Eucalyptus globulus check for this species in other resources e híbrido de Eucalyptus urophylla check for this species in other resources X Eucalyptus grandis check for this species in other resources por Acromyrmex ambiguus check for this species in other resources e Acromyrmex crassispinus check for this species in other resources em laboratório. Para isso, folhas foram ofertadas, simultaneamente, para seis colônias de cada espécie em bioensaios com chance de escolha. No entanto, nos testes sem chance de escolha, apenas as espécies menos preferidas pelo teste anterior foram utilizadas. Para Acromyrmex crassispinus, as espécies Eucalyptus camaldulensis e híbrido de Eucalyptus urophylla X Eucalyptus grandis foram mais cortadas, enquanto que as espécies Corymbia citriodora, Eucalyptus dunnii e Eucalyptus globulus foram menos preferidas ao corte. Acromyrmex ambiguus apresentou padrão similar de preferência, adicionando-se Eucalyptus benthamii entre as mais preferidas e excluindo-se Eucalyptus dunnii das menos preferidas.

Abstract

The search for new leafcutter ant management and control methods have been the aim of several studies over the country, propelled by economic and environmental aspects. The establishment of resistant or less preferred species for the cut can contribute substantially in this subject. This way, the objective of this study was to evaluate the cutting preference between the species Corymbia citriodora check for this species in other resources , Eucalyptus benthamii check for this species in other resources , Eucalyptus camaldulensis check for this species in other resources , Eucalyptus dunnii check for this species in other resources , Eucalyptus globulus check for this species in other resources and híbrido de Eucalyptus urophylla check for this species in other resources X Eucalyptus grandis check for this species in other resources by Acromyrmex ambiguus check for this species in other resources and Acromyrmex crassispinus check for this species in other resources in laboratory. Therefore, leafs were offered simultaneously to six colonies of each species in bioassays with chance to choose. However, in the tests without chance to choose, only the least preferred species in the previous test were utilized. For Acromyrmex crassispinus, the species Eucalyptus camaldulensis and híbrido de Eucalyptus urophylla X Eucalyptus grandis were the most cutted, besides Corymbia citriodora, Eucalyptus dunni and Eucalyptus globules were less preferred. Acromyrmex ambiguus showed similar preference pattern, adding Eucalyptus benthamii among the most preferred one and excluding Eucalyptus dunnii from the least preferred.
