Abstract

The objective of this work was to evaluate the different resistance of commercial E. camaldulensis and E. urophylla clones to the attack of (Glycaspis brimblecombei) Moore (Hemiptera: Aphalaridae). The experiment was carried out between May of 2007 and April of 2008, in João Pinheiro, Minas Gerais State, Brazil, with 5 clones of E. camaldulensis and 5 of E. urophylla. The experimental design was randomized blocks, with 25 plants per plot, and four replications. Four leaves of nine plants were collected in the center of each plot to quantify the number of eggs and nymphs. The highest averages for eggs and nymphs were observed in E. camaldulensis clones, which were classified as highly susceptible to the red-gum-lerp-psyllid attack. Clones of E. urophylla had lower averages for eggs and nymphs, and it was classified as resistant.
