“…Segundo Oehlschlager et al (2002), a média de captura de insetos por armadilha decresceu de 30 para quatro insetos em 80% das armadilhas, com apenas um ano após o início do controle. E decorridos seis anos, não havia mais que dois insetos por armadilha nas avaliações mensais, o que corrobora os dados deste estudo, uma vez que 40% das observações foram de no máximo quatro insetos, refletindo assim o baixo nível de infestação da área.…”

“…Esta discrepância pode ter ocorrido em função da espécie hospedeira, pois para Oehlschlager et al (2002), o inseto manifesta preferência pelo coqueiro quando comparado à palma de óleo. O ambiente também representa uma importante fonte de variação a ser considerada.…”

“…Apenas o monitoramento populacional da praga torna possível a escolha do nível do manejo a ser aplicado e a eficiência do mesmo, sendo fundamental no conhecimento do comportamento da praga, o qual é capaz de aumentar o número de insetos capturados e reduzir os casos de Anel Vermelho (Oehlschlager et al 2002). Assim, o objetivo deste estudo foi monitorar a flutuação populacional de R. palmarum por meio de armadilhas tipo balde em palmeiras do gênero Elaeis produtoras de sementes, localizadas em uma área circundada por floresta, no estado do Amazonas.…”

RESUMOAs coleobrocas são umas das principais pragas das palmeiras devido aos seus danos diretos e indiretos resultarem na morte de diversas plantas. O levantamento populacional destes insetos é de extrema importância, visto a necessidade de se manejar adequadamente o controle realizado na área. Este estudo teve como objetivo monitorar a flutuação populacional de Rhynchophorus palmarum em plantios comerciais de Elaeis guineensis Jacq. e E. oleífera (HBK) Cortes, no estado do Amazonas. Foram distribuídas armadilhas iscadas com roletes de cana-de-açúcar e feromônio de agregação para captura de insetos no entorno do plantio, na Estação Experimental do Rio Urubu, localizada no município de Rio Preto da Eva -AM e pertencente ao Centro de Pesquisa Agroflorestal da Amazônia -Embrapa (CPAA Population dynamic Rhynchophorus palmarum (L.) (Coleoptera: Curculionidae) on oil palm trees in the Amazonas State ABSTRACTThe borers are one of the main pests of palms due to their direct and indirect damages which may result in plant death. The population survey of this insect is important in order to properly handle its control. This study aimed to monitor the population dynamic of Rhynchophorus palmarum in commercial plantations of Elaeis guineensis Jacq. and E. oleifera (HBK) Cortes, in the Amazonas State. For capturing insects, baited traps containing pieces of sugarcane stalk and aggregation pheromone were distributed around the plantation, in the Experimental Station of Rio Urubu, Rio Preto da Eva, AM, Brazil. The data were evaluated for the annual (2005 to 2009) incidence of insects, monthly incidence and frequency of capture. Comparing the years, it was found that the largest amount of insects collected was in 2005, being observed a reduction in captured insects by 2007, then the amount of captured insects increased in 2008 and 2009. For months within a given year no difference was found on the population dynamic of this insect (P > 0,05). Approximately 40% of the collections exceeded four insects, being observed similar behavior in the capture frequency of years studied.

“…Palm weevil cultivation provides an ideal system to document and evaluate TEK in the realm of plant and insect interactions. The current body of scientific research on palm and palm weevil interactions has largely focused on studies in palm plantations because palm weevil infestations have lead to significant economic losses (e.g., Faleiro et al 2003;Oehlschlager et al 2002). As a consequence, palm weevil ecology and behavior in natural forest settings are not well-known (although see .…”

“…Efficient control methods are not available, but farmers trap adults with simple containers baited with fruit (Ministry of Agriculture and Ethiopian Agricultural Research Organization 1999). Traps baited with a combination of food (e.g., fruit) and pheromones have proved to be efficient for control of several beetle species that are pests on commercial crops (Alpizar et al 2002;Oehlschlager et al 2002). Field observations of mating and aggregation in adult P. interrupta led us to suspect that a pheromone could be involved in these behaviors.…”

Pheromone-based Mating and Aggregation in the Sorghum Chafer, Pachnoda interrupta

Adults of the sorghum chafer, Pachnoda interrupta Olivier (Coleoptera: Scarabaeidae: Cetoniinae), form aggregations during the mating period in July, but also in October. The beetles aggregate on food sources, e.g., Acacia spp. trees or sorghum with ripe seeds, to feed and mate. During the mating season, field trapping experiments with live beetles as bait demonstrated attraction of males to unmated females, but not to mated females or males, indicating the presence of a female-emitted sex pheromone. Unmated females combined with banana (food source) attracted significantly more males and females than did unmated females alone. Other combinations of beetles with banana were not more attractive than banana alone. Thus, aggregation behavior appears to be guided by a combination of pheromone and host volatiles. Females and males were extracted with hexane during the mating period, and the extracts were compared by using GC-MS. In a field trapping experiment, 19 compounds found only in females were tested, both singly and in a mixture. Traps baited with one of the female-associated compounds, phenylacetaldehyde, caught significantly more beetles than any other treatment. However, the sex ratio of beetles caught in these traps did not differ from that of control traps and it is possible that other components may be involved in the sex pheromone signal. Furthermore, traps baited with a mixture of all 19 compounds attracted significantly fewer beetles than did phenylacetaldehyde alone.
