| The grevilea, Grevillea robusta (Cunn), species of the Proteaceae family, native of Australia it was introduced in Brazil and in several other countries of the world, for ornamentation, wind breaks and to shade agricultural crops. In general the grevilea has few pests in its area of natural dispersion and also in Brazil. Recently a severe infestation of the cicada Aethalion reticulatum (Hemiptera: Aethalionidae) was verified in experimental plantings of grevilea’s plantation in São Miguel Arcanjo, SP. This is the first verification of A. reticulatum causing damages to G. robusta. A. reticulatum is an sap sucking insect and the damages in grevilea are similar to the observed in fruit plants. |

| The injuries of Ctenarytaina spatulata Taylor, 1977, were characterized through observations in field, laboratory and greenhouse. The first injuries of C. spatulata in Eucalyptus grandis are caused during oviposition. At the point where the egg is inserted, a small black spot appears, which may grow larger, causing the bud death. The insect eliminates large amount of honeydew, accumulating on leaves and apical parts, which starts the proliferation of sooty mold, and fitopathogenic fungi. Leaves of the attacked lants become deformed, smaller than the normal ones, distorted, or with flaws among the ribs and sooty mold reducing the photosynthetic capacity. Due to damages provoked by the bites, oviposition, sooty mold accumulation and other fungi,... |

| Alguns ipês (Tabebuia alba, T. chrysotricha e T. heptaphylla) apresentam folhas jovens deformadas, na forma de enrolamento foliar, em viveiros e na arborização urbana. Uma avaliação foi feita em plantas destas espécies, com idade variando entre 1 mês e 3 anos, no Viveiro Municipal da Barreirinha e em árvores da arborização urbana da cidade de Curitiba, PR. Coletaram-se galhos apicais com sintomas, em cada planta, para a identificação dos insetos associados. Foram encontrados, associados às folhas deformadas, insetos pertencentes às ordens Coleoptera, Hymenoptera, Hemiptera e Diptera. No entanto, foi constatado que o enrolamento do lombo foliar do ipê é provocado por Trioza tabebuiae (Hemiptera: Psylloidea). |
