| Application of concentrated metabolites of Bacillus subtilis - CMBS - (5,000 µg/mL) one and 24 h before or after inoculation of Sphaerotheca fuliginea (3 x 104 conidia/mL) reduced the number of lesions on cucumber leaves by 90-99%. The average number of lesions on control plants was 16.7 per leaf. A wettable powder product formulated with cells (10%) and metabolites (10%) of B. subtilis (WPBS), and CMBS sprayed on cucumber plants (1,000 µg/mL and 10,000 µg/mL) twice a week totally controlled powdery mildew. In the control treatment, 18 days after the first spray, the percent leaf surface covered by lesions was 99.0 and 46.7%, on the cotyledonary and expanded leaves, respectively. In the control treatment, 30 days after the first spray, the percent leaf... |

| ABSTRACT Beauveria bassiana is naturally found in broiler chicken houses, and has been shown to be active against the lesser mealworm, Alphitobius diaperinus. The effectiveness of soil application of B. bassiana in emulsifiable oil-type formulation (Unioeste 4 isolate) to control the lesser mealworm in commercial poultry house was evaluated. The fungus was applied to the dirt floor of poultry house at 4.2 × 109 conidia/m2 (treated aviary) and the insect population was assessed before and 96, 146 and 216 days after application (DAA). In the control aviary, no treatment was performed to control those insects. Molecular techniques were used to confirm the presence of the fungus in dead A. diaperinus. Significant treatment effects were observed, with 56% and... |

| ABSTRACT The endophytic bacteria belong to a larger group of microorganisms that have their life-cycle partly or entirely inside the plant and are located in intra and inter-cellular spaces or in the vascular tissue. These bacteria can be found colonizing aerial parts or roots. This review aims to analyze the colonization strategies of endophytic bacteria through interaction with plants, as well as to highlight the metabolic influence of these organisms in plant tissues, which result in physiological and biochemical changes. Depending on the different mechanisms used internally to colonize a plant, these microorganisms are called obligate, facultative, or passive endophytes. Phytostimulation, biofertilization and biological control are mechanisms that... |

| The pigeon tick Argas reflexus is a pathogen-transmitting soft tick that typically feeds on pigeons, but can also attack humans causing local and systemic reactions. Chemical control is made difficult due to environmental contamination and resistance development. As a result, there is much interest in increasing the role of other strategies like biological control. In this study, the efficacy of three strains (V245, 685 and 715C) of entomopathogenic fungus Metarhizium anisopliae for biological control of three life stages of pigeon tick A. reflexus including eggs, larvae, engorged and unfed adults was investigated under laboratory conditions. Five concentrations of different strains of M. anisopliae ranging from 10³ to 10(7) conidia/ml were used. All... |

| The objective of this work was to evaluate isolates of Trichoderma harzianum regarding biocontrol of common bean seed-borne pathogens, plant growth promotion, and rhizosphere competence. Five isolates of T. harzianum were evaluated and compared with commercial isolate (Ecotrich), Carboxin+Thiram, and an absolute control. Bean seeds of the cultivar Jalo Precoce, contaminated with Aspergillus, Cladosporium, and Sclerotinia sclerotiorum, were microbiolized with antagonists, and seed health tests were carried out. Isolates were evaluated on autoclaved substrate and in field conditions. Ten days after sowing (DAS), plant length was measured. To test rhizosphere competence, isolates were applied in boxes containing autoclaved washed sand, and root colonization... |

| A cultura do tomate na Serra da Ibiapaba, no Estado do Ceará, é considerada uma das atividades agrícolas mais importantes e geradora de divisas para esta região. Entretanto, apresenta como uma das pragas chave a broca pequena, Neoleucinodes elegantalis (Guen.) (Lepidoptera: Pyralidae). Essa praga ocorre geralmente em elevadas infestações, ocasionando danos à produção em até 90%, pela destruição e apodrecimento dos frutos, levando os produtores a realizarem até duas pulverizações por semana. Sua ocorrência foi constatada no Brasil, em 1922, no Ceará, e em 1939, em São Paulo, encontrando-se atualmente disseminada em quase todas as regiões produtoras de tomate do Brasil. Na região Nordeste, a sua ocorrência é generalizada, exceto no Submédio do Vale do São... |

| The rubber tree (Hevea brasiliensis Muell. Arg.) (Euphorbiaceae) is attacked by various species of phytophagous mites in Brazil. Studies conducted in the State of Mato Grosso showed the presence of Agistemus floridanus Gonzalez, 1965 (Stigmaeidae) on rubber trees, associated with the mite Tenuipalpus heveae Baker, 1945. The aim of this work was to study the biology of that predator in the laboratory, when fed with T. heveae as prey. The study was started with 22 eggs, which resulted in 15 females reaching adult hood. To determine the effect of mating on oviposition, 30 females were used; half of those were maintained isolated and the remaining were maintained then with males during the whole adult stage. The stage of egg was the longest, with a duration of... |

| El psílido de la papa [Bactericera cockerelli (Sulc)] es una de las plagas más importantes de las solanáceas, causa daños no sólo por la alimentación sino además por el papel como vector de enfermedades en papa y tomate, lo cual ocasiona pérdidas millonarias en Estados Unidos de América, México y Centroamérica. Debido a esto el uso de plaguicidas contra este insecto se ha incrementado, y con ello los posibles problemas de resistencia a insecticidas, brotes de plagas secundarias y daños al ambiente; entonces es necesario implementar un programa de manejo integrado de esta plaga, donde el control biológico se convierta en una de las herramientas principales, para ello es necesario incrementar el conocimiento de la biología de los enemigos naturales de este... |
