Effect of silicon application to Eucalyptus camaldulensis on the population of ...
Queiroz, Dalva Luiz de; Camargo, Joelma Melissa Malherbe; Dedecek, Renato Antonio; Oliveira, Edilson Batista; Zanol, Keti Maria RochaThe use of silicon in forestry has increased recently as it is directly related to improved resistance to insect pests. The red gum lerp psyllid, Glycaspis brimblecombei, occurs in all eucalypt producing regions in Brazil. Two field experiments were conducted to study the effect of silicon applied to Eucalyptus camaldulensis on the psyllid population. In the first experiment, the applications were made via soil...
Resistence of Eucalyptus clones to the red gum lerp psyllid
Camargo, Joelma Melissa Malherbe; Zanol, Keti Maria Rocha; Queiroz, Dalva Luiz de; Dedececk, Renato Antonio; Oliveira, Edilson BatistaThe 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 bloc...
