| Outlines economic threshold models developed by various authors as an aid to decision-making about pest management. Particular attention is given to the models proposed by Stern et al. (1959) and by Headley (1972) and the major differences in their concepts of the economic threshold. Limitations and scope for applying these models is discussed as well as differences in the extent of their applications are reviewed. After considering general issues in this respect, particular matters are given attention such as difficulties raised by complexities in the nature of yield loss function due to uncertainty in pest densities, the presence of multiple-pests, and the occurrence of pesticide resistance. An extension is provided for multiple species pest models to... |

| Abstract: Antifeedant and repellent effects of two different extracts from native Solanum species Solanum bistellatum and Solanum sisymbrifolium on Cryptotermes brevis were evaluated. The extracts obtained, particularly the dichloromethane extracts and the enriched fraction of sugar esters from S. sisymbrifolium and S. bistellaltum, showed antifeedant and repellent action against the termite. The antifeedant effect of dichloromethane extract from S. sisymbrifolium at the concentration of 25.00mg/mL reached 100%, while the repellent action of the dichloromethane extracts and that of the enriched fraction of sugar esters at the concentration of 1.00mg/mL was higher than 90%. In case of S. bistellatum, the antifeedant effect of the dichloromethane extract and... |

| Agaricus subrufescens, known as Sun Mushroom, is a high-value mushroom because of its medicinal properties, used as nutraceutical food to stimulate the immune system and to prevent some diseases, including cancer. Mushrooms are generally characterized by their great ability to bioaccumulate heavy metals and other toxic substances from the mushroom compost. Sugarcane bagasse is a common raw material used in mushroom compost production for Agaricus subrufescenscultivation, whereas insecticides, such as fipronil, can be applied to combat several pests in sugarcane crops. For this reason, we aimed to assess mushroom yield and fipronil bioaccumulation in Sun Mushroom, regarding different concentrations added to the mushroom compost (0, 8, 16 and 32 mg kg-1) and... |

| Plantios de cupuaçu em monocultivos ou como componentes de sistemas agroflorestais (SAFs) são amplamente disseminados na Amazônia brasileira. Em ambas as formas de plantio há ocorrência de insetos associados à cultura, destacando-se os pertencentes à ordem Coleoptera e Lepidoptera, conhecidos popularmente por besouros e mariposas, respectivamente. Espécies pertencentes a essas ordens são broqueadores de frutos e/ou de madeira, causando prejuízos consideráveis, dependendo dos seus níveis populacionais. Dentre os lepidópteros considerados pragas do cupuaçuzeiro, Magulacra nigripennata Dognin (Lepidoptera: Cossidae), conhecida popularmente como "broca-do-ramo-terminal", "lagarta-flamenguista" ou "broca-dos-ramos", é uma das espécies de relevância econômica. |

| The objective of this study was to characterize the Peruvian isolate of Metarhizium anisopliae var. acridum, CG 863, obtained from the grasshopper Schistocerca interrita, a crop pest in Peru. The characterization was done by comparing this isolate with two other ones of M. anisopliae var. acridum, from Brazil and Australia, and with an isolate of M. anisopliae var. anisopliae. The three M. anisopliae var. acridum isolates had similar growth profiles in agar plates at 25°C and 37°C, and similar RAPD patterns according to the analysis of three primers. However, regarding these parameters and conidial size, these isolates were very distinct when compared to M. anisopliae var. anisopliae isolate. Bioassays indicated that the Peruvian isolate is as pathogenic... |

| The Thaumastocoris peregrinus spread to eucalyptus plantations in many countries. Chemical control is a questionable measure, mainly due to the environmental impact, high cost and moreover has the use restricted by the forest certifcations. Bio-insecticides may have similar efciency to chemical products to control T. peregrinus. The chemical thiamethoxam, thiamethoxam+lambda-cyhalothrin, acephate and the microbial Beauveria bassiana and Metarhizium anisopliae insecticides were tested at diferent doses to manage T. peregrinus. The products were sprayed on eucalyptus plants using aircraft and populations of this insect were counted before application and at 1, 14 and 21days afterwards (DAA). Ten eucalyptus trees were evaluated per plot, with the collection... |

| Todos os anos, com a chegada das chuvas, as cigarrinhas-das-pastagens, principal praga que ataca os capins tropicais, começam a causar transtornos para os pecuaristas. Em alguns anos, notadamente após um período seco mais pronunciado, a incidência e a severidade dos ataques costumam ser mais intensas, o que pode causar a morte de capins suscetíveis e a degradação da pastagem. Isso exige atenção por parte de toda a equipe da fazenda, que deve estar preparada para reconhecer o problema e combater a praga. A estratégia mais importante para amenizar os problemas causados por essa praga é a diversificação das pastagens na fazenda, com o plantio de capins tolerantes e resistentes. |
