| The beetle Alphitobius diaperinus (Panzer), considered a worldwide pest in the poultry industry, is difficult to control and it is a vector for pathogens. The objective of this study was to evaluate the biological control of the lesser mealworm, by strains of fungi Beauveria bassiana, Cladosporium sp. and Trichoderma sp. Larvae and adults of the A. diaperinus were inoculated with suspensions of conidia in the concentration of 10(7) conídia.mL-1. The B. bassiana isolate caused higher insect mortality as compared to Cladosporium sp. and Trichoderma sp. isolates, with the larvae being more susceptible than adults. The entomopathogenicity of B. bassiana was further evaluated with 200 larvae and 200 adults of A. diaperinus inoculated with suspensions 10(6),... |

| The objective of the present study was to evaluate mortality and performance, darkling beetle population (Alphitobius diaperinus), light intensity, electrical energy consumption and economic efficiency of broilers reared under two lighting programs (nearly continuous or intermittent) and two curtain colors (yellow or blue). The experiment was conducted between June, 2004 and May, 2005. Six flocks were sequentially housed in four 12 × 10 m broiler houses divided into 4 pens with 200 birds each. Litter was reused six times or until flock 6. Body weight and feed conversion were determined on days 21, 35, and 42 of each flock. Mortality was recorded daily. Electrical energy consumption was recorded at the end of the grow-out of each flock (every 42 days). A... |

| Resumo: O objetivo deste trabalho foi avaliar o efeito do extrato de tabaco no controle do besouro cascudinho [Alphitobius diaperinus (Coleoptera: Tenebrionidae)] de aviário. O experimento foi conduzido em delineamento inteiramente casualizado, com quatro tempos de contato (21/2, 5, 71/2 e 10 min) e quatro concentrações do extrato de tabaco (0, 25, 50 e 75% de diluição). O tempo de contato e as diluições do extrato foram independentes; entretanto, o tempo de contato exerceu maior influência na mortalidade do inseto. O extrato de tabaco tem potencial inseticida no manejo de aviários, mas testes de toxicidade devem ser realizados com as aves. |

| O objetivo deste trabalho foi avaliar a interferência dos métodos de bioensaios nos resultados de seleção de fungos entomopatogênicos, com a utilização de quatro isolados de Beauveria bassiana e adultos de Alphitobius diaperinus. Quanto à forma de inoculação, foram testados os seguintes métodos: imersão do inseto em suspensão de conídios; pulverização da suspensão sobre insetos; e tratamento de superfície com a suspensão em oito concentrações. Para avaliar a interferência do tempo de imersão sobre a mortalidade, os insetos foram colocados em suspensão de conídios por 1, 10, 20, 30, 40, 50 e 60 segundos. Conídios produzidos em arroz, insetos e meio sintético foram utilizados para avaliar a influência do substrato na virulência dos isolados. Os isolados... |

| ABSTRACT The aim of this study was to evaluate the in vitro bioactivity of tea tree (Melaleuca alternifolia) essential oil against larvae and adult forms of lesser mealworms (Alphitobius diaperinus) and its influence on the soil fauna. Tests were performed in triplicate using pure tea tree oil (TTO; 1, 5, 10, 25, 50, and 100%), TTO nanoparticles (1, 3, and 7.5%), or terpinen-4-ol, the main compound of the tea tree oil, at the same concentrations of TTO. Larvae and adult mortality occurred at concentrations up to 10 and 50% of TTO, respectively. No larvicidal or insecticidal effect of TTO nanoparticles was observed. Terpinen-4-ol showed insecticidal and larvicidal effect at concentrations higher than 25%. The evaluation of TTO effect on soil organisms was... |

| A estabilidade de ambiência na avicultura moderna tem favorecido a proliferação de insetos praga. Nesse cenário, Alphitobius diaperinus (Panzer) (Coleoptera: Tenebrionidae), comumente denominado cascudinho, surge como principal inseto cosmopolita infestando camas de aviários. Neste sentido o objetivo deste trabalho foi avaliar os fatores cal hidratada, temperatura e umidade na cama de aviários sobre a mortalidade de A. diaperinus em condições de laboratório. Foram realizados bioensaios laboratoriais simulando o ambiente de criação em recipientes com a adição de cama de aviário, ração e adultos e larvas de A. diaperinus. A variável resposta foi a mortalidade aos sete e 10 dias após a instalação dos experimentos. A adição de cal hidratada na cama de aviário... |

| The seasonality of Alphitobius diaperinus population was studied during different seasons during one year, in broiler facilities located in the center-north region of the State of São Paulo. Parasite counting was weekly carried out by the use of traps adapted from the modified model of Arends. During the experimental period, facilities were not submitted to chemical treatment, and the litter was changed between flocks. A lower number of adults and larvae was observed during autumn, with the peak registered in the summer. There was no significant difference between spring and winter averages (adults and larvae), and between spring and summer averages (adults). Average temperatures in the facilities varied from 23.4ºC (winter) to 27.1ºC (spring). The... |

| 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... |
