| No Brasil, o ácaro ectoparasita de abelhas Varroa destructor Anderson e Trueman (Acari: Varroidae) se mantém em índices de infestação baixos, não causando grandes prejuízos. Todavia com a introdução e possível predominância de um novo haplótipo (K) do ácaro, geralmente encontrado em regiões com altas taxas de infestação (TI), faz-se necessário o monitoramento e seleção de colônias resistentes à praga, evitando problemas futuros. Vários fatores são relacionados como possíveis responsáveis pela dinâmica de infestação do ácaro, dentre os quais se destaca o comportamento higiênico (CH). Nesse contexto buscamos avaliar o CH de abelhas africanizadas Apis mellifera L. (Hymenoptera: Apidae) correlacionando com as TI do ácaro em apiários de dois municípios do... |

| Bactericera cockerelli es una de las plagas más importantes en solanáceas en México. Su manejo se basa en el uso de insecticidas y recientemente se ha explorado el uso del parasitoide Tamarixia triozae dentro de un programa de MIP. El objetivo del presente trabajo fue explorar la compatibilidad de insecticidas con este parasitoide. En este trabajo se evaluó, en condiciones de laboratorio (25±2ºC, 60±5% H.R.), la toxicidad de Azadiractina, Spinosad, Imidacloprid y Abamectina sobre T. triozae y B. cockerelli. Los cuatro insecticidas resultaron tóxicos tanto para el psílido como para el parasitoide, aunque el grado de toxicidad dependió de la especie, insecticida, estado biológico específico, dosis y forma en que los insectos se expusieron a los productos. De... |

| This research aimed to catalog insects that cause injury to the yacon (Smallanthus sonchifolius, família Asteraceae) crop, in order to identify those who may cause damage. The study was carried out in Alegre, Espírito Santo State, Brazil. Cultivation began in May 2013 and the harvest was done 180 days later. Three species from the Coleoptera order: Lagria villosa (Coleoptera: Lagriidae); Cerotoma arcuata and Diabrotica speciosa (Coleoptera: Chrysomelidae) and two species from the Lepidoptera order: Spodoptera eridania (Lepidoptera: Noctuidae) and Chlosyne lacinia saundersii (Lepidoptera: Nymphalidae) were observed causing damage to the yacon crop. The caterpillar C. lacinia saundersii, known as sunflower caterpillar, was the most important species, being... |

| This study determined the main mite species on rubber trees (clone RRIM-600) in Piracicaba, southeast of São Paulo State, from June 2002 to May 2003 and evaluated the possible relation between them. It was conducted in a plantation of 5 ha on 11 year old trees, 15 m high, surrounded with crops as pearl millet, cotton, bean or corn. Samples were taken monthly and consisted of five leaflets, five petioles (only from October 2002 on) and five terminal sections of twigs (10 cm) from 15 rubber trees. All mites of one leaflet, one petiole and one twig section of each plant were mounted for identification to genera/species to estimate the proportional occurrence of each species. A total of 84,850 mites belonging to 38 species of 34 genera and 16 families were... |

| Development of alternative methods for pest management is needed with the increased concern for adverse effects of pesticides for human health and the environment. The main goal of our study was to test the oil from seeds of sugar apple (Annona squamosa), an edible tropical fruit for pest control. The oil pressed out of seeds was as effective in controlling the silverleaf whitefly, Bemisia argentifolii Bellows & Perring (Homoptera: Aleyrodidae), infesting leaves of tomato plants in greenhouse conditions as the recommended insecticide, with the advantage of not being phytotoxic. When observed with a scanning electron microscope, the seed oil caused whitefly nymphs to shrink and detach from the leaf surface. Sugar apple seed oil was also very... |

| The objective of this work was to predict the occurrence of alates of Brevicoryne brassicae, Lipaphis erysimi, and Myzus persicae (Hemiptera, Aphididae) in Brassicaceae. The alate aphids were collected in yellow water traps from July 1997 to August 2005. Aphid population peaks were predicted using a degree‑day model. The meteorological factors, temperature, air relative humidity, rainfall, and sunshine hours, were used to provide precision indexes to evaluate the best predictor for the date of the first capture of alate aphids by the traps. The degree‑day model indicated that the peak population of the evaluated aphid species can be predicted using one of the following biofix dates: January 1st, June 1st, and the date of the first capture of the alate... |

| The objective of this work was to screen plants with insecticide activity, in order to isolate, identify and assess the bioactivity of insecticide compounds present in these plants, against Coleoptera pests of stored products: Oryzaephilus surinamensis L. (Silvanidae), Rhyzopertha dominica F. (Bostrichidae) and Sitophilus zeamais Mots. (Curculionidae). The plant species used were: basil (Ocimum selloi Benth.), rue (Ruta graveolens L.), lion's ear (Leonotis nepetifolia (L.) R.Br.), jimson weed (Datura stramonium L.), baleeira herb (Cordia verbenacea L.), mint (Mentha piperita L.), wild balsam apple (Mormodica charantia L.), and billy goat weed or mentrasto (Ageratum conyzoides L.). The insecticide activity of hexane and ethanol extracts from those plants on... |

| Adoption of genetically engineered crops with traits for pest management has risen dramatically since their commercial introduction in the mid-1990's. The farm-level impacts of such crops on pesticide use, yields, and net returns vary with the crop and technology examined. Adoption of herbicide-tolerant cotton led to significant increase in yields and net returns, but was not associated with significant changes in herbicide use. On the other hand, increase in adoption of herbicide-tolerant soybeans led to small but significant increases in yields, no changes in net returns, and significant decreases in herbicide use. Adoption of Bt cotton in the Southeast significantly increased yields and net returns and significantly reduced insecticide use. |

| The rice stink bug is a major pest of rice in Texas, causing quality related damage. The previous threshold used for assisting in rice stink bug spray decisions lacked flexibility in economic and production decision variables and neglected the dynamics of the pest population. Using stochastic dynamic programming, flexible economic thresholds for the rice stink bug were generated. The new thresholds offer several advantages over the old, static thresholds, including increased net returns, incorporation of pest dynamics, user flexibility, ease of implementation, and a systematic process for updating. |

| Ecological engineering has recently emerged as a paradigm for considering pest management approaches that are based on cultural practices and informed by ecological knowledge rather than on high technology approaches such as synthetic pesticides and genetically engineered crops (Gurr et al. 2004a). This article provides a brief summary of ecological engineering for arthropod pest management and contrasts it with its controversial cousin, genetic engineering. The development of ecological engineering is explored, ranging from a simple first approximation that diversity is beneficial, to contemporary understanding that diversity can have adverse effects on pest management. This requires that the functional mechanisms that lead components of biodiversity to... |
