Resistence of Eucalyptus clones to the red gum lerp psyllid

Resistence of Eucalyptus clones to the red gum lerp psyllid

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.

O experimento foi conduzido entre maio de 2007 e abril de 2008, em João Pinheiro, MG, com cinco clones de E. camaldulensis e cinco de E. urophylla. O delineamento experimental foi de blocos ao acaso, contendo 25 plantas por parcela, com quatro repetições. Mensalmente foram coletadas quatro folhas das nove plantas centrais de cada parcela, quantificando o número de ovos e ninfas do inseto. As maiores médias para ovos e ninfas foram observadas para os clones de E. camaldulensis, os quais foram classificados como altamente suscetíveis ao ataque do psilídeo-de-concha. Os clones de E. urophylla apresentaram menores médias para ovos e ninfas, sendo classificados como resistentes.
