The Red Ring Disease is an infectious plant disease caused by nematodes. The etiological agent, Bursaphelencus (Rhadinaphelencus) cocophilus (Nematoda: Aphelenchoididae), completes its life cycle within 9 to 10 days inside the palm tree. The main symptom is a permanent wilting of the plant aerial parts. Previous studies stated that B. cocophilus cohabits with other nematodes the gut of R. palmarum. The aim of this study is to identify nematodes collected from palm weevil found in coconut plantations from the north of the Rio de Janeiro State. Light (LM) and scanning electron microscopy (SEM) analyses were carried on samples of infected R. palmarum and fragments and fresh juice of infected plants with B. cocophilus. Observations of R. palmarum fecal material made by LM and SEM showed three species cohabiting these samples, being also present in fresh juice and fragments of infected coconut tree: B. cocophilus, Teratorhabditis palmarum (Nematoda: Rhabditidae) and Diplogasteritus sp (Nematoda: Diplogasteridae). These findings confirm previous studies, which related that R. palmarum own a varied nematode fauna. Nematodes associated to B. cocophilus probably could be co-participates of the etiology of the Red Ring disease.10aRhynchophorus palmarum1 aMagalhaes, J., A. S.1 aNeto, A., H.

Many surveys show the diversity of insects consumed by man, and their high nutritive value. In the Peruvian Amazonia, one of the favourite species is the larva of Rhynchophorus palmarum (Coleoptera Dryophthoridae). The most important host plant of this insect is the palm tree Mauritia flexuosa, which grows naturally in swampy areas. The larvae, or "sun", develop in the stipes cut down for fruit collecting. The production methods of the Kukama-Kukaminia indians have been studied, as well as the commercialization in the markets of the town of Iquitos. It appears that the average monthly revenue amounts to 800 soles (= 200 euros). A better exploitation of the trunks could make this product more profitable.10aRhynchophorus palmarum1 aDelgado, Cesar1 aCouturier, Guy1 aMathews, Paul1 aMejia, Kember  uhttps://weevil.myspecies.info/production-and-commercialization-larva-rhynchophorus-palmarum-coleoptera-dryophthoridae-peruvian-ama02037nas a2200193   4500008004100000020001400041245010800055210006900163260001800232300001200250490000700262520133700269653002901606653002701635100001801662700002001680700002301700856012001723       2009                        eng d  a0278-077100aThe importance of traditional ecological knowledge for palm-weevil cultivation in the Venezuelan Amazon0 aimportance of traditional ecological knowledge for palmweevil cu  cSpring-Summer  a113-1280 v293 aEntomophagy is widespread among indigenous people, promoting the gathering of traditional ecological knowledge of insect life histories and plant-insect interactions. In the Amazon, the cultivation of palm weevil larvae (Rhynchophorus palmarum and Rhinostomus barbirostris) for food provides an important supplement to the diets of many indigenous people. This study conducted with the Joti people from Venezuelan Amazonia examined their traditional ecological knowledge (TEK) of palm (Oenocarpus bacaba) and weevil interactions and how they have applied their TEK to optimize returns on palm weevil cultivation. They manipulate palms to induce changes in the resource-partitioning and competition that occurs naturally between weevil species, thereby increasing harvests of their preferred species of weevil. We found that the joti's traditional ecological knowledge was congruent with scientific findings of weevil natural history and palm and weevil interactions. This analysis identifies potential research directions that may provide solutions to agricultural problems such as palm weevil infestations in palm plantations. We conclude that understanding and preserving traditional ecological knowledge and practices is important for organisms such as palm weevils that rarely have been studied in their natural forest settings.10aRhinostomus barbirostris10aRhynchophorus palmarum1 aChoo, Juanita1 aZent, Eglee, L.1 aSimpson, Beryl, B.  uhttps://weevil.myspecies.info/importance-traditional-ecological-knowledge-palm-weevil-cultivation-venezuelan-amazon02180nas a2200229   4500008004100000020001400041245020500055210006900260260001100329300001200340490000800352520129600360653002701656100002001683700001601703700001801719700001801737700001801755700002001773700002201793856013501815       2009                        eng d  a1210-575900aPurification and characterization of a novel thermoacidophilic and thermostable alpha -mannosidase from the digestive fluid of oil palm weevil Rhynchophorus palmarum (Coleoptera: Curculionidae) larvae0 aPurification and characterization of a novel thermoacidophilic a  cMay 20  a185-1910 v1063 aAn extracellular [alpha]-mannosidase with unusual properties was purified from the digestive fluid of oil palm weevil (Rhynchophorus palmarum Linnaeus) larvae using ammonium sulphate saturation, size exclusion and anion-exchange chromatography. The enzyme named RpltM is thermoacidophilic, thermostable and behaves like lysosomal [alpha]-mannosidase (EC 3.2.1.24). The molecular weight, Km value, optimum reaction temperature and pH are 108-112 kDa, 0.36 mM, 65[degree]C and 4.5, respectively. Zn2+ enhanced whereas Cu2+ Sodium dodecyl sulphate, swainsonine and 1,4-dideoxy-1,4-iminomannitol strongly inhibited its hydrolytic activity. The enzyme was stable for 25 min at 65[degree]C and retained 70% of its initial activity after 60 min. At 70[degree]C, around 60% of this activity was conserved after 25 min. RpltM retained more than 90% of its activity over a pH range of 4.2 to 5.0 and remained fully active in the presence of detergents such as nonidet P-40, triton X-100, polyoxyethylen-10-oleyl ether (up to 1%, w/v), dithiothreitol and [beta]-mercaptoethanol. The stability under these conditions is also better than that reported for other insect [alpha]-mannosidases. Thus, RpltM could be used as an important bioindustrial tool for removing mannose residues from oligosaccharides.10aRhynchophorus palmarum1 aBedikou, Micael1 aAhi, Pascal1 aKone, Martial1 aFaulet, Betty1 aGonnety, Jean1 aKouame, Patrice1 aNiamke, Sebastien  uhttps://weevil.myspecies.info/purification-and-characterization-novel-thermoacidophilic-and-thermostable-alpha-mannosidase-digesti02255nas a2200229   4500008004100000020001400041245012200055210006900177260000900246300001000255490000700265520143200272653002701704100002301731700002001754700002301774700002201797700002201819700002301841700002601864856013501890       2009                        eng d  a1721-886100aBiochemical properties of extracellular alpha -mannosidases from the digestive fluid of Rhynchophorus palmarum larvae0 aBiochemical properties of extracellular alpha mannosidases from   cJune  a75-840 v623 aThree extracellular [alpha]-mannosidases (EC 3.2.1.24) were purified from the digestive fluid of oil palm weevil larvae. Rhynchophorus palmarum (L.) and characterized in order to explore their potential for biotechnological application. Three steps procedure including size exclusion, anion exchange and hydrophobic interaction chromatography were Used. The enzymes named Rp/M1, Rp/M2 and Rp/M3 had native molecular weights of approximately 125, 72 and 111 kDa, respectively and functioned as dimeric (Rp/M1) and monomeric (Rp/M2 and Rp/M3) Structures. The three [alpha]-mannosidases displayed acidic and mesophilic activities by using para-nitrophenyl-[alpha]-D-Mannopyranoside as substrate. Apparent KM values were found to be 0.13, 0.22 and 0.16 nM for Rp/M1, Rp/M2 and Rp/M3, respectively. Ba2+, Ca2+, Mg2+, Zn2+ and ethylene diamine tetra acetic acid (EDTA) had no effect oil the three enzyme activities whereas detergents and reducing agents were inhibitors. Rp/M1, Rp/M2 and Rp/M3 were more sensitive to swainsonine and cleaved [alpha]-1,2: [alpha]-1,3 and [alpha]-1.6 linked mannobioses. These characteristics prompted LIS to categorize them as catabolic [alpha]-mannosidases. Thus, they would help in the larval oil palm weevil nutrition allowing digestion by the removal of mannose residues in the beetle's diet. Also, these enzymes could find potential application in biological, biochemical and pharmaceutical area.10aRhynchophorus palmarum1 aBedikou, Ehuie, M.1 aAhi, Amedee, P.1 aKone, Fankroma, M.1 aGonnety, Jean, T.1 aFaulet, Betty, M.1 aKouame, Lucien, P.1 aNiamke, Sebastien, L.  uhttps://weevil.myspecies.info/biochemical-properties-extracellular-alpha-mannosidases-digestive-fluid-rhynchophorus-palmarum-larva
