Electrophysiological responses of eucalyptus brown looper Thyrinteina arnobia t...
Batista-Pereira,Luciane G.; Fernandes,João B.; Corrêa,Arlene G.; Silva,M. Fátima G. F. da; Vieira,Paulo C.Eucalyptus is frequently attacked by the Brazilian eucalyptus brown looper, Thyrinteina arnobia. This caterpillar is regarded as the main lepidopterous pest of Eucalyptus and yet no practical and environmentally acceptable method of control currently exists. Electroantennographic techniques (EAG) have never before been used to detect semiochemicals that affect the behavior of T. arnobia. Thus, in this work, the...
Inhibition of the symbiotic fungus of leaf-cutting ants by coumarins
Godoy,Marizete F. P.; Victor,Sandra R.; Bellini,Adriana M.; Guerreiro,Gisleine; Rocha,Waldireny C.; Bueno,Odair C.; Hebling,Maria J. A.Leaf-cutting ants are known to be a serious pest for agriculture due to the high amounts of vegetal matter from crops used by them in order to cultivate a symbiotic fungus on which they rely for food and enzymes. The mutualism between the fungus and the ants is a point to be explored when alternative methods of control are being thought of. Considering that some plants are naturally resistant to phytophagous in...
