CUTTING PREFERENCE OF Acromyrmex crassispinus (FOREL, 1909) AND Acromyrmex ambiguus (EMERY, 1887) (HYMENOPTERA: FORMICIDAE) BY DIFFERENT EUCALYPT SPECIES IN LABORATORY
A busca por novos m\ue9todos de manejo e controle de
formigas-cortadeiras vem sendo enfoque de in\ufameros estudos pelo
pa\ueds, impulsionada por aspectos econ\uf4micos e ambientais. O
estabelecimento de esp\ue9cies resistentes ou menos preferidas ao
corte pode contribuir substancialmente neste sentido. Logo, o objetivo
deste estudo foi avaliar a prefer\ueancia de corte entre as
esp\ue9cies Corymbia citriodora , Eucalyptus benthamii , Eucalyptus
camaldulensis , Eucalyptus dunnii , Eucalyptus globulus e
h\uedbrido de Eucalyptus urophylla X Eucalyptus grandis por
Acromyrmex ambiguus e Acromyrmex crassispinus em laborat\uf3rio.
Para isso, folhas foram ofertadas, simultaneamente, para seis
col\uf4nias de cada esp\ue9cie em bioensaios com chance de escolha.
No entanto, nos testes sem chance de escolha, apenas as esp\ue9cies
menos preferidas pelo teste anterior foram utilizadas. Para Acromyrmex
crassispinus, as esp\ue9cies Eucalyptus camaldulensis e h\uedbrido
de Eucalyptus urophylla X Eucalyptus grandis foram mais cortadas,
enquanto que as esp\ue9cies Corymbia citriodora, Eucalyptus dunnii e
Eucalyptus globulus foram menos preferidas ao corte. Acromyrmex
ambiguus apresentou padr\ue3o similar de prefer\ueancia,
adicionando-se Eucalyptus benthamii entre as mais preferidas e
excluindo-se Eucalyptus dunnii das menos preferidas.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 ,
Eucalyptus benthamii , Eucalyptus camaldulensis , Eucalyptus dunnii
, Eucalyptus globulus and h\uedbrido de Eucalyptus urophylla X
Eucalyptus grandis by Acromyrmex ambiguus and Acromyrmex
crassispinus 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
h\uedbrido 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
