a weevil pollinating the canary islands date palm: between parasitism and mutualism.palm pollination systems are highly diverse, including by wind and by several different groups of insects. many palm species are associated with more or less specific pollinating weevils that are also floral herbivores. for many such palms, the importance of these "palm flower weevils" as pollinators has not been examined. here we describe a new ex situ method of demonstrating insect pollination when pollinator exclusion is not possible. we show that neoderelomus piriformis beetles carry pollen ...200314564403

a set of 100 chloroplast dna primer pairs to study population genetics and phylogeny in monocotyledons.chloroplast dna sequences are of great interest for population genetics and phylogenetic studies. however, only a small set of markers are commonly used. most of them have been designed for amplification in a large range of angiosperms and are located in the large single copy (lsc). here we developed a new set of 100 primer pairs optimized for amplification in monocotyledons. primer pairs amplify coding (exon) and non-coding regions (intron and intergenic spacer). they span the different chlorop ...201121637837

pathogenicity bioassays of isolates of beauveria bassiana on rhynchophorus ferrugineus.the control of rhynchophorus ferrugineus (olivier), the main palm pest in the mediterranean basin, is problematic because of its biology and the current restrictions in many european countries on the use of chemical insecticides in urban areas. entomopathogenic fungi have been studied as potential biological control agents, but information on their natural incidence is limited. strains of beauveria bassiana (balsamo) vuillemin were isolated from symptomatic insects collected on dead palms, and t ...201524990249
could sterile males be used to vector a microbiological control agent? the case of rhynchophorus ferrugineus and beauveria bassiana.rhynchophorus ferrugineus (coleoptera, curculionidae) is the most threatening pest of palms worldwide. the potential of gamma-irradiated males to spread a pathogenic strain of the entomopathogenic fungus beauveria bassiana (ascomycota: clavicipitaceae) to control this pest was studied. first, the effects of gamma irradiation (15 and 25 gy) on the mating success and performance of adult males irradiated at age one day were studied in the laboratory. although male longevity decreased after irradia ...201323034248
evaluation of an oil dispersion formulation of imidacloprid as a drench against rhynchophorus ferrugineus (coleoptera, curculionidae) in young palm trees.background: the red palm weevil, rhynchophorus ferrugineus (olivier), is a phytophagous insect that feeds on soft succulent tissues of most palm species and is considered the main palm pest in the middle east and the mediterranean basin. the aim of this study was to test the efficacy of imidacloprid oil dispersion (od) as a drench in preventive and curative treatments against r. ferrugineus in phoenix canariensis, washingtonia robusta, washingtonia filifera and trachycarpus fortunei. results: le ...201122262504
basic bio-ecological parameters of the invasive red palm weevil, rhynchophorus ferrugineus (coleoptera: curculionidae), in phoenix canariensis under mediterranean climate.the invasive red palm weevil, rhynchophorus ferrugineus olivier (coleoptera, curculionidae), is one of the most destructive pests of palms in the world. since its detection in the mediterranean basin, the ornamental phoenix canariensis hort. ex chabaud has become its main host. this study was aimed at determining the life cycle of r. ferrugineus in live p. canariensis palms. egg lethal temperature threshold and thermal constant were determined in the laboratory and resulted in 13.1°c and 40.4 de ...201120822555
evaluation of the efficacy of an insecticidal paint based on chlorpyrifos and pyriproxyfen in a microencapsulated formulation against rhynchophorus ferrugineus (coleoptera: curculionidae).the weevil rhynchophorus ferrugineus (olivier) (coleoptera: curculionidae) is an important pest of palms. it has recently colonized the mediterranean basin where it is a serious problem on ornamental phoenix canariensis (hort. ex chabaud) palms. the efficacy of an insecticidal paint based on chlorpyrifos and pyriproxyfen in a microencapsulated formulation (inesfly igr fito, industrias químicas inesba s.l., paiporta, spain) against this weevil has been studied. laboratory results proved that pyri ...201020429455
potential of an indigenous strain of the entomopathogenic fungus beauveria bassiana as a biological control agent against the red palm weevil, rhynchophorus ferrugineus.the potential of a strain of beauveria bassiana (ascomycota: clavicipitaceae) obtained from a naturally infected rhynchophorus ferrugineus (coleoptera: curculionidae) pupa as a biological control agent against this weevil was evaluated both in the laboratory and in semi-field assays. laboratory results indicate that this strain of b. bassiana can infect eggs, larvae and adults of r. ferrugineus (lc(50) from 6.3 x 10(7) to 3.0 x 10(9) conidia per ml). however, mortality was not the only indicator ...201020398670
field efficacy of imidacloprid and steinernema carpocapsae in a chitosan formulation against the red palm weevil rhynchophorus ferrugineus (coleoptera: curculionidae) in phoenix canariensis.the invasive red palm weevil, rhynchophorus ferrugineus (olivier), has become the major pest of palms in the mediterranean basin. chemical control against this species is difficult because of its cryptic habits and is mainly based on the repeated application of large quantities of synthetic insecticides. the aim of this work has been to evaluate in the field the efficacy of imidacloprid (confidor 240 od) and steinernema carpocapsae weiser with chitosan (biorend r palmeras) as soil and stipe trea ...201019924729
rapid detection of the fusarium oxysporum lineage containing the canary island date palm wilt pathogen.abstract fusarium oxysporum f. sp. canariensis causes fusarium wilt disease on the canary island date palm (phoenix canariensis). to facilitate disease management, a polymerase chain reaction diagnostic method has been developed to rapidly detect the pathogen. a partial genomic library of f. oxysporum f. sp. canariensis isolate 95-913 was used to identify a dna sequence diagnostic for a lineage containing all tested isolates of f. oxysporum f. sp. canariensis. two oligonucleotide primers were de ...199918944754
autofluorescence detection of arbuscular mycorrhizal fungal structures in palm roots: an underestimated experimental method.the aim of this study was to reassess the use of autofluorescence for evaluating am colonization in mycorrhizal roots in the light of criticisms of this method that affirmed that only metabolically inactive arbuscules autofluoresce. it was also investigated whether other mycorrhizal structures, such as hyphae, vesicles and spores, could be detected by autofluorescence, and whether the autofluorescence pattern of am fungal structures could be exploited methodologically, for example, in the detect ...200616893637
allozyme variation and structure of the canarian endemic palm tree phoenix canariensis (arecaceae): implications for conservation.electrophoretic analysis of 18 allozyme loci was used to estimate the levels and structuring of genetic variation within and among natural populations of the protected endemic palm species from the canary islands (phoenix canariensis) to evaluate its genetic relationship with the widespread congener p. dactylifera, and to assess comparatively the genetic variation in the populations where the two species coexist with morphologically intermediate plants (mixed populations). our survey revealed th ...200415241448
occupational rhinoconjunctivitis and bronchial asthma due to phoenix canariensis pollen allergy.we report a case of occupational bronchial asthma and rhinoconjunctivitis caused by phoenix canariensis (pc) pollen. the canary palm is a type of palm tree, belonging to the arecaceae family, which is widely distributed in frost-free regions as an ornamental tree. our patient was referred because he suffered symptoms of bronchial asthma, rhinoconjunctivitis, and contact urticaria when pruning dried leaves from pc during the pollination months. the skin prick test (spt) with a pc pollen extract w ...19957677245
