Autores: Cruz,Wilton Pires da; Sarmento,Renato Almeida; Teodoro,Adenir Vieira; Erasmo,Eduardo Andrea Lemus; Pedro Neto,Marçal; Ignacio,Maíra; Ferreira Junior,Diogenis Fontenele.
O objetivo deste trabalho foi identificar ácaros na cultura de pinhão-manso e em espécies de plantas espontâneas associadas. Para isso, foram avaliadas a riqueza e a abundância de ácaros em plantas de pinhão-manso e em 14 espécies de plantas espontâneas associadas. As amostragens foram realizadas por meio de coletas mensais de folhas de plantas de pinhão-manso e de plantas espontâneas, nas entrelinhas do cultivo. Foram encontradas quatro espécies de ácaros predadores - Amblyseius tamatavensis, Paraphytoseius multidentatus, Typhlodromalus aripo e Typhlodromalus clavicus -, com potencial para uso no controle biológico de ácaros-praga na cultura do pinhão-manso, e duas importantes espécies de ácaros fitófagos - Brevipalpus phoenicis e Tarsonemus confusus -...

Autores: Teodoro,Adenir Vieira; Carvalho,Hélio Wilson Lemos de; Barros,Inácio de; Carvalho,Luciana Marques de; Martins,Carlos Roberto; Soares Filho,Walter dos Santos; Girardi,Eduardo Augusto; Passos,Orlando Sampaio.
Abstract: The objective of this work was to evaluate the effect of nine rootstocks on 'Jaffa' sweet orange (Citrus sinensis) for its vegetative, productive, and qualitative traits, and for its susceptibility to three pest mites (Eutetranychus banksi, Tetranychus mexicanus and Phyllocoptruta oleivora). The following parameters were evaluated: vegetative growth, yield, physiochemical characteristics of fruit, and density of pest mites. 'Sunki Tropical' mandarin conferred high cumulative yields whereas 'Orlando' tangelo and 'Rugoso Vermelho' lemon imparted bigger fruit with low brix, and less acidity to 'Jaffa'. Indio and 'Riverside' citrandarins induced more acid fruit of smaller sizes, as well as low-cumulated yields and canopy volumes. Also, the 'Cravo...

Provedor de dados: 86
Autores: Carvalho,Hélio Wilson Lemos de; Martins,Carlos Roberto; Teodoro,Adenir Vieira; Soares Filho,Walter dos Santos; Passos,Orlando Sampaio.
Abstract The objective of this work was to evaluate the agronomical performance of 'Piemonte' mandarin grafted on 11 rootstocks grown under the edaphoclimatic conditions of the Coastal Tablelands, in the state of Sergipe, Brazil. The following combined agronomical parameters were evaluated: vegetative growth, abundance of phytophagous mites, plant yield, drought tolerance, and physicochemical quality of fruit. 'Piemonte' mandarin had the best productive performance when grafted on 'Santa Cruz Rangpur' lime, 'Red Rough' lemon, 'Sunki Tropical' mandarin, and 'Riverside' citrandarin, and it was more tolerant to drought when grafted on 'Santa Cruz Rangpur' lime and on the LVK x LCR-010 hybrid. Rootstocks did not affect pest population levels. 'Piemonte'...

Seasonal population abundance of the assembly of solitary wasps and bees (Hymenoptera) according to land-use in Maranhão state, Brazil
Provedor de dados: 92
Autores: Matos,Michela Costa Batista; Silva,Shênia Santos; Teodoro,Adenir Vieira.
ABSTRACT Solitary wasps and bees (Hymenoptera) play a key role in ecosystem and agroecosystem functioning. Crops may benefit from biological pest control and pollination carried out by predatory solitary wasps and solitary bees, respectively. Here, we aimed at evaluating the abundance and faunistic compositions of solitary wasps and bees in respect to land-use (pasture, alley cropping, young fallow and old fallow) over an entire year using trap nests in the Brazilian northeastern state of Maranhão. Land-use did not influence the abundance of solitary wasps and bees, however, levels of dominance, abundance and frequency of the species Pachodynerus guadulpensis Saussure, Isodontia sp. 1, Isodontia sp. 2, Trypoxylon nitidum Smith and Megachile cfr. framea...

Apple biological and physiological disorders in the orchard and in postharvest according to production system
Provedor de dados: 94
Autores: Martins,Carlos Roberto; Hoffmann,Alexandre; Rombaldi,Cesar Valmor; Farias,Roseli de Mello; Teodoro,Adenir Vieira.
The study aimed to evaluate the incidence of biological and physiological disorders in the field and postharvested apples cvs. Gala, Fuji and Catarina grown in four production systems: conventional, organic transition, integrated and organic. Apples were evaluated for damages related to biological and physiological disorders in the orchard and after harvest. The greatest damages were attributed to pests, especially Anastrepha fraterculus in the organic system and Grapholita molesta in the organic transition. Apples produced in organic orchards had higher damage levels caused by postharvest physiological disorders than those grown in other production systems. For apples becoming from organic orchards most of the damage was due to lenticels breakdown and...

Forest fragments' contribution to the natural biological control of Spodoptera frugiperda Smith (Lepidoptera: Noctuidae) in Maize
Provedor de dados: 52
Autores: Sousa,Eduardo Henrique Santana; Matos,Michela Costa Batista; Almeida,Ruanno Silva; Teodoro,Adenir Vieira.
The present work evaluated the influence of forest distance on predatory solitary wasps' abundance and richness and its relation to the natural biological control of the fall armyworm (Spodoptera frugiperda Smith - Lepidoptera: Noctuidae) in maize. The study consisted of two parallel lines of six experimental maize plots located at an increasing distance from a forest edge. Four trap-nests were placed in the vertices of each plot of the first line to evaluate the abundance and species richness of predatory solitary wasps. The larvae of the fall armyworm were sampled weekly by inspecting ten randomly chosen plants per plot. Predatory solitary wasp abundance (but not species richness) decreased whilst the fall armyworm abundance increased with the distance...

No evidence of coconut stem bleeding disease transmission by bark beetles in Brazil
Provedor de dados: 65
Autores: Guzzo,Elio Cesar; Neves,Jhonatan David Santos das; Santana,Samuel Farias; Negrisoli Junior,Aldomario Santo; Teodoro,Adenir Vieira.
ABSTRACT: Stem bleeding disease, caused by the fungus Thielaviopsis paradoxa is one of the most important diseases of coconut palm Cocos nucifera worldwide and some insect species have been found in association with T. paradoxa infected coconut palms. The present research investigated whether coconut palm-infesting bark beetles (Coleoptera: Curculionidae: Scolytinae) could disseminate stem bleeding disease. Adult bark beetles collected from coconut palms presenting stem bleeding symptoms were inoculated in PDA culture medium. Results showed no germination of the fungus T. paradoxa from either cuticle or digestive tract of bark beetles. Thus, we found no evidence that bark beetles carry viable spores of T. paradoxa that could infect healthy coconut palms...

Citrus rootstocks influence the population densities of pest mites
Provedor de dados: 65
Autores: Silva,Rafael Rocha da; Teodoro,Adenir Vieira; Vasconcelos,Jéssica Fontes; Martins,Carlos Roberto; Soares Filho,Walter dos Santos; Carvalho,Hélio Wilson Lemos de; Guzzo,Elio Cesar.
Citrus are attacked by pest mites such as the citrus rust mite Phyllocoptruta oleivora (Ashmead) (Acari: Eriophyidae) and the spider mite Tetranychus mexicanus (McGregor) (Acari: Tetranychidae). However, little is known on citrus rootstocks influencing pest mites. We aimed to evaluate the influence of rootstocks on population densities of pest mites on the sweet oranges 'Pera CNPMF D-6' and 'Valencia Tuxpan' throughout time. Adults of both mite species were monthly counted during 19 months from June 2011 to February 2013. Rootstocks influenced the populations of pest mites, since lower densities of P. oleivora were found on 'Pera CNPMF D-6' sweet orange grafted on the hybrid TSKC × CTTR - 002 and on 'Swingle' citrumelo in comparison with the hybrid LVK ×...

O ácaro Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) é importante em cafeeiro (Coffea spp.), por ser o vetor do vírus da mancha-anular, responsável por queda de folhas e má qualidade da bebida do café, e o ácaro-vermelho, Oligonychus ilicis (McGregor, 1917) (Acari: Tetranychidae), por reduzir a área foliar de fotossíntese. Alguns ácaros da família Phytoseiidae são eficientes predadores associados aos ácaros-praga. Com este trabalho teve-se como objetivo estudar o controle dos ácaros-praga e o impacto do abamectin e emamectin sobre fitoseídeos. Em laboratório, foram estudados os efeitos ovicida, tópico, residual, tópico mais residual aos ácaros-praga e a seletividade fisiológica aos fitoseídeos. Em semicampo, foi estudada a persistência dos...
