| Con el propósito de identificar las plagas asociadas al mango así como también evaluar los insecticidas como son aceite mineral, azufre, spinosad e imidacloprid contra ellas, se realizó un estudio en la región de Costa Grande, Guerrero, México. La aplicación de estos productos se realizó con base de umbrales de acción. Se empleó un diseño experimental de bloques al azar con cinco tratamientos incluyendo el testigo, con cuatro repeticiones. Se registraron temperatura y humedad para correlacionarlas con las poblaciones. Las especies predominantes fueron Frankliniella invasor y Aulacaspis tubercularis, no hubo correlación significativa entre las poblaciones de ambas plagas y la temperatura, pero hubo correlación negativa con la humedad. Los tratamientos no... |

| En el estado de Tabasco, localizado en el trópico de México, se tienen plantadas alrededor de 7,000 ha de cedro (Cedrela odorata L), como una respuesta a los procesos de deforestación de la región y como una forma de suplir las necesidades de materia prima de la industria de la madera. La presente investigación tuvo como objetivo evaluar el crecimiento del cedro en etapa juvenil bajo riego, fertilización y aplicación de insecticida y su relación con la incidencia de Hypsipyla grandella Zeller. El estudio se desarrolló de abril a de septiembre de 2008 en una plantación de cedro de 10 meses de edad plantada en marco real de 3x3 m, con una densidad de 1100 plantas/ha, localizada en el municipio de Cárdenas, Tabasco (18°01´N, 93°03´ W). Las variables... |

| A mosca-dos-chifres é considerada um sério problema econômico à pecuária devido aos prejuízos causados à produção e gastos com controle. Este estudo objetivou conhecer o perfil da comercialização e uso dos produtos inseticidas para controle da mosca-dos-chifres no município de Aquidauana, MS. De nov/1999 a nov/2000, informações foram obtidas em estabelecimentos agropecuários na cidade de Aquidauana e em entrevistas com produtores rurais e gerentes de fazendas. Um total de 29 produtos indicados para o controle da mosca foram encontrados nos estabelecimentos, pertencentes aos grupos dos piretróides (58,6%), organofosforados (3,4%), fenil pirazoles (3,4%), lactonas macrocíclicas (3,4%) e associações entre inseticidas (31,0%). A cipermetrina foi o princípio... |

| Within the framework of the study on cup oyster breeding in the Arcachon Basin (IFREMER's SURGIBA Programme, co-financed by Europe, the Regional Council of Aquitaine, the Regional Council of Gironde and the Arcachon Basin's inter-communal Syndicate), some pesticides have been researched in the main waterways and in the waters of several of the Basin's zones (Figure 1), during the summer months (June to September) from 1999 to 2003 inclusive (Auby and Maurer, 2004). The presence of a certain number of molecules, mainly from herbicides, was found in the waters and it has generally been possible to identify their source. Certain substances come from agricultural uses or park maintenance; others are from nautical sources (anti-fouling paint for protecting the... |

| Curly top in sugarbeet can result in severe yield losses and is caused by Beet severe curly top virus (BSCTV) and other closely related Curtovirus spp. which are vectored by the beet leafhopper. Neonicotinoid seed treatments (Cruiser, NipsIt, and Poncho) have been shown to be an effective supplement to host resistance, but measures to extend control beyond the duration of seed treatment efficacy needs to be investigated. In 2012, a field study was arranged in a randomized complete block design with 8 replications and planted with the cultivar B-42. The 16 treatments included untreated and Poncho Beta treated seed with and without 6 foliar insecticides (applied 7 days before and 6 days after release of viruliferous beet leafhopper) and just Poncho and... |

| Insect feeding and vectoring of viruses cause serious problems in sugarbeet production worldwide. In order to ameliorate insect and disease problems on sugarbeet, two seed treatments, Poncho Beta (60 g a.i. clothianidin + 8 g a.i. beta-cyfluthrin/100,000 seed) and Cruiser Tef (60 g a.i. thiamethoxam + 8 g a.i. tefluthrin/100,000 seed) were investigated (the neonicotinoid was tested alone in some trials). The two seed treatments and an untreated check were tested in a series of seven field trials from 2006 to 2008 along with various commercial sugarbeet cultivars in a randomized complete block design with eight replications per trial. Natural insect incidence and curly top symptoms were evaluated. Both Poncho and Cruiser provided significant reduction... |

| Sucrose loss in sugarbeet storage is a concern for all roots, but particularly those stored under ambient conditions. In order to control or suppress insect issues in sugarbeet production and consequently improve root storability, two neonicotinoid seed treatments, Poncho Beta (60 g a.i. [active ingredient] clothianidin + 8 g a.i. beta-cyfluthrin/100,000 seeds) and Cruiser Tef (60 g a.i. thiamethoxam + 8 g a.i. tefluthrin/100,000 seeds), were used to produce roots from four commercial sugarbeet cultivars grown in Declo, ID. At harvest, eight-beet samples from each cultivar-treatment combination were collected and placed inside an outdoor pile. Samples were removed on approximately 30-day intervals beginning on December 6 and 8 in 2008 and 2009,... |

| Curly top caused by Curtovirus species is a widespread disease problem vectored by the beet leafhopper in semiarid sugar beet production areas. The insecticide seed treatment Poncho Beta has proven to be effective in controlling curly top in sugar beet, but was only evaluated under light to moderate disease pressure. Thus, the insecticide seed treatments Poncho Beta, NipsIt INSIDE, and Cruiser Force were evaluated under severe curly top pressure (6 viruliferous beet leafhoppers per plant) in field studies during the 2010 and 2011 growing seasons on two commercial sugar beet cultivars. In addition, the foliar insecticides Movento, Provado, and Scorpion were also evaluated. The seed treatments and Scorpion reduced curly top symptoms by 33 to 41% (P... |

| Curly top in sugar beet caused by Beet curly top virus (BCTV) is an important yield limiting disease that can be reduced via neonicotinoid and pyrethroid insecticides. However the length of efficacy of these insecticides is poorly understood, so a series of field experiments was conducted with the seed treatment Poncho Beta (60 g a.i. clothianidin + 8 g a.i. beta-cyfluthrin/100,000 seed) and foliar treatment Asana (55.48 g a.i. esfenvalerate/ha). A series of four experiments were conducted in 2014 and repeated in 2015 with four treatments (untreated check, Poncho Beta, Asana, and Poncho Beta + Asana) which were arranged in a randomized complete block design with 8 replications. To evaluate efficacy, viruliferous (contain BCTV strains) beet leafhoppers... |
