| The giant African snail Achatina fulica Bowdich, 1822 was introduced into Paraná, Brazil, in the 1980s. Since then, it has spread across the country, despite its known invasive status on a global scale. The main objective of this study was to assess the problems faced in the management of the giant African snail. To accomplish that, we gathered and analyzed information available on the internet, scientific databases, field studies, as well as interviews and consultations with official agencies, NGOs, museums, the scientific community and people that coexist with the species. Despite the fact that extensive information has been generated regarding A. fulica (1,340 articles, 65 summaries in national annals, 40,700 pages on the internet), essential to promote... |

| 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... |

| La guanábana tiene un gran futuro en el mercado mexicano y de exportación; sin embargo, su producción se ve afectada por el ataque de plagas y enfermedades. B. cubensis es una de las plagas que causan mayores pérdidas económicas al cultivo de guanábana en México. Se han observado 60% de frutos dañados y de 5 a 50 semillas con daño por fruto, lo cual ocasiona pérdidas en la producción de hasta 25%. En Nayarit, se han determinado, en algunos casos, 100% de los frutos atacados. Los productores de la región, realizan aplicaciones de plaguicidas sin lograr un control efectivo. Con base en lo anterior, se plantearon los siguientes objetivos: determinar el ciclo de vida y hábitos de B. cubensis en guanábana en condiciones de campo y evaluación de... |

| The invasive aquatic plants Hydrilla verticillata (hydrilla), Eichhornia crassipes (water hyacinth), and Pistia stratiotes (water lettuce) have the potential to negatively impact recreational use of Florida lakes if consistent, adequate control expenditures are not made. In the mid-1990's, Florida significantly reduced its spending on invasive aquatic plant control measures, which resulted in a significant increase in needed control expenditures in subsequent years. This paper attempts to formalize a relationship between coverage of these invasive aquatic plants and angler effort on Florida lakes using data on 38 lakes over 20 years. Estimated regression coefficients are used to simulate control alternatives, and expenditure cost-benefit comparisons are... |

| The bacterial spot of tomato, caused by Xanthomonas spp., is a very important disease, especially in the hot and humid periods of the year. The chemical control of the disease has not been very effective for a number of reasons. This study aimed to evaluate, under greenhouse conditions, the efficacy of leaf-spraying chemicals (acibenzolar-S-methyl (ASM) (0.025 g.L−1), fluazinam (0.25 g.L−1), pyraclostrobin (0.08 g.L−1), pyraclostrobin + methiran (0.02 g.L−1 + 2.2 g.L−1), copper oxychloride (1.50 g.L−1), mancozeb + copper oxychloride (0.88 g.L−1 + 0.60 g.L−1), and oxytetracycline (0.40 g.L−1)) on control of bacterial spot. Tomatoes Santa Clara and Gisele cultivars were pulverized 3 days before inoculation with Xanthomonas perforans. The production of... |

| Human activities are altering greenhouse gas concentrations in the atmosphere and causing global climate change. In the near future, there will certainly be changes in the Brazilian phytosanitary scenario attributed to global climate change. The impacts of climate change can be positive, negative or neutral, since these changes can decrease, increase or have no impact on diseases, depending on each region or period. These impacts will also be observed on plants and other organisms as well as on other agroecosystem components. However, these impacts are not easily determined, and consequently, specialists from several areas must go beyond their disciplinary boundaries and placing the climate change impacts in a broader context. This review focuses on the... |
