“…and T. rhynchophori (Pymotidae) have been recorded infesting the adult weevil, but the status of these species as parasites is uncertain (peter 1989), although Acari have been proposed as a biocontrol agent against insects (Welbourn & young 1988). The studies on the natural enemies of R. palmarum in the Neotropic have only revealed that this weevil is attacked by members of the parasitic dipterans family, Tachinidae; P. Menezesi palm (Moura et al 1993; and P. rhynchophorae (guiMaraes et al 1977) have been also identified in Brazil as ectoparasites. Association of R. palmarum with mites may affect the population dynamics of the weevils and/or its behavior.…”

Abstract. Palm weevils have been reported as a pest and red ring nematode vectors for several palms of the Arecaceae family. Rhynchophorus palmarum L (Coleoptera: Curculionidae) is a pest for coconut crop and other palms. It is vector of Bursaphelenchus cocophilus (Cobb) Baujard (Nematoda) etiological agent of Red Ring disease and other nematodes. Current methods recommended use of enemies and parasites in integrated pest management of Rhynchophorinae. In addition, mass trap reduce environmental damage. The objectives of our study on coconut plantations were: (1) to determine the efficiency of low expensive kariomones traps and (2) low expensive kariomones and pheromones traps using adult males; and (3) to examine R. palmarum using light and scanning electron microscopy searching for ectoparasites which can be proposed in integrated pest management. Handmade kariomones mass traps were efficient to R. palmarum and other Curculionidae capture but kariomones plus adult male R. palmarum was maintained inside trap enhanced its attractiveness for this palm weevil and Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae). R. palmarum presented occasionally fungal infection. In contrast, mites infested more than 50% of palm weevils. Infestation level was always high. Surface morphology of the mites and its interaction with R. palmarum were briefly described. All stages of ectoparasites life cycle were observed onto weevil elytra compartments. In this way, morphological evidences suggest the hypothesis of these mites as used as biological control agent in R. palmarum integrated pest management.Keywords: Coconut palm; Curculionidae; Integrated Pest Management; Light and Electron Microscopy; Mites. Coleta Massal e Controle Biológico de Rhynchophorus palmarum L.:Uma hipótese baseada me evidências morfológicasResumo. Coleópteros têm sido descritos como pragas e vetores de nematódeos causadores de Anel Vermelho em diversas palmeiras da família Arecaceae. Rhynchophorus palmarum L (Coleoptera: Curculionidae) é uma praga que afeta a cocoicultura e outras palmeiras; e, vetor de Bursaphelenchus cocophilus (Cobb) Baujard (Nematoda), agente etiológico de Anel Vermelho e de outros nematódeos. Atualmente, recomendase o emprego de inimigos naturais e parasitas no manejo integrado de pragas; dentre elas, Rhynchophorinae. Armadilhas de coleta massal são recomendadas no manejo integrado de pragas. Nosso estudo relata, na cocoicultura, a eficiência de armadilhas artesanais de baixo custo e a utilização cariomônios (toletes de cana-de-açúcar) e cariômonios mais feromônios (toletes de cana-de-açúcar e machos adultos de R. palmarum) como atrativos nas armadilhas. Ácaros ectoparasitas foram identificados nestes coleópteros, por microscopia, que podem ser propostos como parte do manejo integrado desta praga. Armadilhas de coleta massal com cariômonios foram eficientes na captura de R. palmarum e outros Curculionidae. No entanto, armadilhas de coleta massal com cariômonios e feromônios aumentaram a atratividade, em relação às primeiras, par...

Esta pesquisa teve como objetivo avaliar a ﬂutuação populacional de Rhynchophorus palmarum L. (Coleoptera: Curculionidae) em plantios de Elaeis guineensis Jacq, em ecossistemas de savana e floresta no estado de Roraima. A pesquisa foi desenvolvida durante o período de janeiro de 2011 a fevereiro de 2012 nos campos experimentais da Embrapa Roraima: Monte Cristo e Caroebe, numa área de 2 hectares com a cultura da Palma de Óleo, em cada campo. Foram distribuídas armadilhas iscadas com roletes de cana-de-açúcar e feromônio de agregação para captura dos insetos no entorno dos plantios. Ocorreu flutuação de R. palmarum com picos populacionais nos meses de julho e agosto no ecossistema de savana e de abril a setembro no ambiente de floresta. A população de R. palmarum foi menor em meses de baixa precipitação pluviométrica nos dois ambientes avaliados com a Palma de Óleo em RoraimaPopulation Fluctuation of Rhynchophorus palmarum L. (Coleoptera: Curculionidae) in Plantations of Oil Palm in RoraimaAbstract. This research aimed to evaluate the population fluctuation Rhynchophorus palmarum L. (Coleoptera: Curculionidae) in Elaeis guineensis Jacq plantations in forest and savanna ecosystems in the state of Roraima. The research was conducted during the period from January 2011 to February 2012 in the experimental field of Embrapa Roraima: Monte Cristo and Caroebe in an area of 2 hectares with culture Oil Palm in each field. Traps baited with rollers cane sugar and aggregation pheromone for capturing insects in the vicinity of the plantations were distributed. Fluctuation occurred R. palmarum with population peaks in the months of July and August in the savanna ecosystem and from April to September in the forest environment. The population of R. palmarum was lower in months of low rainfall in the two environments assessed with a palm-oil-in Roraima.

“…A armadilha Alçapão consistiu de balde plástico de 65 litros com tampa, dentro do qual foram colocados 15 toletes amassados de cana-de-açúcar com 40 cm de comprimento cada, conforme Moura et al (1990). Sob a tampa do balde foram feitos quatro orifícios eqüidistantes e em cada um deles foi acoplado com arames um funil plástico de 10 cm de diâmetro, com a parte estreita do funil cortada e voltada para o interior do balde para permitir a passagem dos insetos.…”
