RESUMO
Abstract Costalimaita ferruginea (Coleoptera: Chrysomelidae) attacks Eucalyptus plants causing severe damage through netting of the leaves. Recently, this Coleoptera has been reported attacking Myrtaceae in Mato Grosso State and, studies about the occurrence of this beetle in commercial plantations of eucalypts has been the subject of researchers through monitoring programmes in the forest protection area. With the beginning of the rainy season, adults were observed causing damage in eucalypt plantations in four cities that are part of the transition region of Amazon and Cerrado Biomes. The spots where these insects were observed are located in Feliz Natal, Lucas do Rio Verde, Sorriso and Vera. The purpose of this study was to report the new occurrences and to characterize the attack period of the beetle C. ferruginea in Eucalyptus plantations in Middle-North region of Mato Grosso State, region of Biomes Transition.

Recentemente, esse Coleoptera tem sido relado atacando Myrtaceae no Estado de Mato Grosso e, estudos sobre a ocorrência desse besouro em plantios comerciais de eucaliptos tem sido alvo de pesquisadores através de programas de monitoramento na área de proteção florestal. Com o início do período chuvoso, adultos foram observados causando danos em plantios de eucalipto em quatro municípios que fazem parte da região de transição dos Biomas Amazônia e Cerrado. Os pontos onde foram observados esses insetos estão localizados em Feliz Natal, Lucas do Rio Verde, Sorriso e Vera. O objetivo deste trabalho foi relatar as novas ocorrências e caracterizar o período de ataque do besouro C. ferruginea em plantios de Eucalyptus na região Médio-Norte do Estado de Mato Grosso, região de transição de Biomas.

RESUMO
Desflurane anesthesia in low or intermediate oxygen flow rates were compared in dogs regarding its effects on heart rate (HR) and electrocardiography (ECG). In this experiment, 26 adult healthy mongrel dogs, males and females, weighing 32.04 ± 4.0 kg, were used. Dogs were randomly assigned to two equal groups (G1 and G2). In both groups, general anesthesia was induced with propofol (8.0 ± 2.0 mg/kg IV), followed by inhalation anesthesia with desflurane (7.2V% expired), diluted in oxygen (O2) at a flow rate of 50 mL/kg/min, using a semi-closed anesthetic system. After 15 35 minutes, O2 flow was decreased to 7 mL/kg/min and 30 mL/kg/min for G1 and G2 animals, respectively. After reducing O2 flow rate, the pop-off valve was closed for G1 animals, resulting in a closed anesthetic circuit. Parameters were measured immediately before the drugs were given (M0) and 15 minutes after anesthetic induction (M15), with repeated data collection at 15-minute intervals (M30 to M60). Statistical analysis was performed by Profile Analysis (p£0.05). We concluded that low flow anesthesia does not cause threatening changes in heart rate or in electrocardiographic parameters. KEY-WORDS: Anesthesia. Dogs. Desflurane. Low flow. Electrocardiography.
