Última Eucalyptus grandis Hill.ex. Maiden injuries caused by Ctenarytaina spatulata Taylor. PFB - Pesquisa Florestal Brasileira 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,...

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...
