| Tetra magnolivora (Keifer, 1939) (Acari, Eriophyidae) new combination was observed infesting Magnolia grandiflora L., in urban areas of Curitiba, Paraná State, Brazil. This mite was observed in high populations on magnolia trees, causing wrinkles, distortion and decreased growth in infested leaves. This is the first record from Brazil for T. magnolivora and we provide new combination. |

| 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... |

| O objetivo deste trabalho foi avaliar a resistência de clones comerciais de E. camaldulensis e E. urophylla ao ataque de Glycaspis brimblecombei Moore (Hemiptera: Aphalaridae). 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.... |

| Glycaspis brimblecombei Moore, 1964, (Hemiptera: Psyllidae) is an insect of Australian origin which can cause severe damage on the production of different species of Eucalyptus. In Brazil, its presence was first described in the State of Sao Paulo in 2003 and it is present in several states such as Paraná, Goiás, Minas Gerais, Santa Catarina, Rio Grande do Sul, Espírito Santo and Bahia. The occurrence of this insect in Pernambuco in Petrolina municipality on a small stand of Eucalyptus spp. confirms the dispersive and adaptive potential of this specie.doi: 10.4336/2010.pfb.30.63.253 |
