| The eucalypt shoot psyllid, Blastopsylla occidentalis Taylor, 1985 (Hemiptera: Psylloidea), is reported here for the first time from Burundi, Indonesia (Sumatra), Nicaragua, the Philippines and Yemen. The record from Paraguay is shown to be erroneous. New state records are given for the Brazilian states Bahia, Ceará, Piauí and Rio Grande do Sul. Eucalyptus viminalis is listed for the first time as host of B. occidentalis. |

| The 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 (calcium silicate) and leaves (potassium silicate) in a nine months old E. camaldulensis plantation. In the second experiment, we evaluated silicon on seedlings, incorporating it into the substrate (soil) or applying it on leaves (foliar). Monthly, for 24 months, the number of psyllid eggs and immatures were counted on leaf samples. The plant height... |
