Aethalion reticulatum (Linnaeus, 1767) (Hemiptera: Aethalionidae) in Grevillea robusta
Provedor de dados: 190
Autores: Santana, Dalva Luiz de Queiroz; Ferreira, Carlos Alberto; Martins, Emerson Gonçalves; Silva, Helton Damin da.
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.

Insetos Associados ao Enrolamento Foliar de Tabebuia spp. em Viveiros e na Arborização Urbana de Curitiba
Provedor de dados: 190
Autores: Santana, Dalva Luiz de Queiroz; Auer, Celso Garcia; Rocha, Ana Lucia Jarretta Loyola; Marques, Elaine.
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).

Eucalyptus grandis Hill.ex. Maiden injuries caused by Ctenarytaina spatulata Taylor.
Provedor de dados: 190
Autores: Santana, Dalva Luiz de Queiroz; Zanol, Keti M. R.; Botosso, Paulo Cesar; Mattos, Patricia Póvoa de.
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,...

Ctenarytaina spatulata, Taylor: soil water, mineral nutrients and their relations to eucalyptus dieback
Provedor de dados: 190
Autores: Santana, Dalva Luiz de Queiroz; Bellote, Antonio Francisco Jurado; Dedecek, Renato Antonio.
To develop this study it was used Eucalyptus grandis seedlings planted in three-liter pots, filled with soil collected on areas where dieback occurred (Arapoti, PR). The experiment consisted of six soil water level treatments, with and without insects. The experimental design was randomized blocks with 6 replications, arranged in six cages inside a green house. Three cages received insects and other three, not. The experiment consisted of the following treatments: 1. Sat. - soil water content maintained on the saturated conditions; 2. CC – soil water content maintained on field capacity; 3. 60 - humidity of the soil to 60% of the field capacity; 4. 30 - humidity of the soil to 30% of the field capacity; 5. A7 – soil water content maintained 7 days on the...
