Bactérias do gênero Staphylococcus estão entre os principais agentes causadores da mastite ovina. Um dos maiores entraves ao tratamento dos animais doentes são cepas resistentes aos antimicrobianos empregados. A pesquisa do gene mecA nos estafilococos é um instrumento auxiliar para a determinação de aspectos epidemiológicos da doença. Este trabalho teve por objetivo investigar a resistência à oxacilina em estafilococos coagulase-negativos isolados no leite de ovelhas com mastite subclínica. Foram analisadas 448 amostras de leite de dois rebanhos. Os micro-organismos isolados foram submetidos previamente a testes de sensibilidade a antibióticos in vitro a partir da técnica de difusão em disco. Naqueles resistentes à oxacilina nestes testes efetuou-se a... |

he objective of this study was to analyze the development, reproductive parameters and consumption capacity of Harmonia axyridis, using Cinara atlantica as food. The average time of egg incubation was 3 d, duration of larval instars was 3.5, 2, 2.2 and 4.1 d, respectively, and duration of the pupal stage was 5.8 d. Longevity was 85.6 d and the life cycle lasted 107.2 d. Egg viability was 92.7% and all stages had 100% survival. Adults consumed, on average, 1.892 aphids. Pre-oviposition, oviposition and post-oviposition periods lasted 6.8, 44.3, and 32.9 d, respectively. Fertility was 633.2 eggs per female. Each instar consumed, on average, 19.4, 24.8, 49.7 and 188.9 aphids, respectively. The life table results, together with biological data, indicated that... |

Abstract Knowledge of the population fluctuation and spatial distribution of pests is fundamental for establishing an appropriate control method. The population fluctuation and spatial distribution of the Alphitobius diaperinus in a poultry house in Cascavel, in the state of Parana, Brazil, was studied between October, 2001 and October 2002. Larvae and adults of the lesser mealworm were sampled weekly using Arends tube traps (n = 22) for six consecutive flock grow-outs. The temperature of the litter and of the poultry house was measured at the same locations of the tube traps. Beetle numbers increased continuously throughout all the sampling dates (average 5,137 in the first week and 18,494 insects on the sixth week). Significantly greater numbers of... |

The pathogenicity of insect-pathogenic hyphomycetous isolates to the lesser mealworm Alphitobius diaperinus (Panzer) was tested in this study. Thirty isolates of Beauveria bassiana (Balsamo) Vuillemin, Paecilomyces amoenoroseus (Hennings), P. fumosoroseus (Wize) Brown& Smith, P. lilacinus (Thom) Samson, P. tenuipes (Petch) Samson, Metarhizium anisopliae (Metschnikoff) Sorokin, and M. anisopliae var. acridum were initially screened by sprinkling dry conidia onto adult A. diaperinus or by allowing adults to walk on Petri dishes with sporulating fungal isolates. The two most virulent isolates, CNPSo-Ma352 (M. anisopliae) and CNPSo-Ma356 (M. anisopliae), killed 30% and 26.7% of the dry-conidia treated adults, respectively. These two isolates were selected... |
