The occurrence of the tachinid parasitoid Billaea rhynchophorae (Blanchard) on larvae of the palm weevil Rhynchophorus palmarum (L.) was evaluated in plantations of piassava palm (Attalea funifera Mart.) and African oil palm (Elaeis guineensis Jacquin), in southeastern Bahia, Brazil. The monthly percentages of parasitism were evaluated during 13 months, from November 2000 to November 2001, based on the comparison between the number of parasitized and non-parasitized cocoons of R. palmarum. Mean parasitism was 40% and ranged from 50% in November 2000 to 18% in July 2001. While there is no method of mass reproduction of the parasitoid, a simple management practice is recommended, in order to preserve its beneficial effects in palm plantations.

The palm weevil, Rhynchophorus palmarum (L.), was collected in cocoons from red ring-diseased coconut palms (Cocos nucifera L.) in Trinidad and Tobago. Juveniles of five species of nematodes were extracted from the genitalia and macerated bodies of newly emerged adults of the palm weevil: Rhadinaphelenchus cocophilus (Cobb) Goodey (the red ring nematode), Teratorhabditis sp., Diplogasteritus sp., Mononchoides sp., and Bursaphelenchus sp. Over 90% of newly emerged weevil females and males were infested internally with red ring nematode juveniles, and over 47% of the weevils contained more than 1,000 red ring nematodes each. There was no significant correlation between weevil body length and the number of red ring nematodes carried internally by each weevil. Teratorhabditis sp. and Diplogasteritus sp. were extracted from over 50% of the palm weevils, and Monochoides sp. and Bursaphelenchus sp. were found in a small proportion of the weevils. Field-collected adult weevils were also internally and externally infested with a Rhabditis sp., which was not observed in or on weevils allowed to emerge from field-collected cocoons.

The red palm weevil Rhynchophorus ferrugineus Olivier (Curculionidae/Rhynchophoridae/Dryophthoridae) is a lethal pest of young coconut palms, Cocos nucifera L. (Arecales: Arecaceae), with a highly aggregated population distribution pattern. R. ferrugineus is managed in several coconut growing countries using area-wide pheromone based programmes that need a substantial commitment of funds over a period of time. Often, decisions to implement area-wide management of R. ferrugineus are based on pheromone trap captures in surveillance traps and or infestation reports. Implementing area-wide management of this pest on the basis of such data can be inaccurate, as it may either under or over estimate the pest intensity in the field. This study presents sampling plans for rapid and accurate classification of R. ferrugineus infestation in coconut plantations of India by inspecting palms to detect infestation in a sequence until a decision to either implement or not to initiate area-wide management of R. ferrugineus can be made. The sampling plans are based on a common aggregation index of 3.45, assumed action threshold values of either 1.0 (plan A) or 0.5 (plan B) per cent infested palms and a risk factor of making the wrong decision set at 0.05. Using plans A and B...

During the last two decades Red Palm Weevil (RPW, Rynchophorus Ferrugineus) has become one of the most dangerous threats to palm trees in many parts of the World. Its early detection is difficult, since palm trees do not show visual evidence of infection until it is too late for them to recover. For this reason the development of efficient early detection mechanisms is a critical element of RPW pest management systems. One of the early detection mechanisms proposed in the literature is based on acoustic monitoring, as the activity of RPW larvae inside the palm trunk is audible for human operators under acceptable environmental noise levels (rural areas, night periods, etc.). In this work we propose the design of an autonomous bioacoustic sensor that can be installed in every palm tree under study and is able to analyze the captured audio signal during large periods of time. The results of the audio analysis would be reported wirelessly to a control station, to be subsequently processed and conveniently stored. That control station is to be accessible via the Internet. It is programmed to send warning messages when predefined alarm thresholds are reached, thereby allowing supervisors to check on-line the status and evolution of the palm tree orchards. We have developed a bioacoustic sensor prototype and performed an extensive set of experiments to measure its detection capability...

The earwig, Anisolabis maritima (Dermaptera: Carcinophoridae), is one of the most significant insects in KSA because, it was recorded in Saudi Arabia as a beneficial predator on eggs and newly hatched larvae of the red palm weevil, Rhyncophorus ferrugineus. We examined the external morphology of the antennal sensilla of males and females of A. maritima using scanning electron microscopy (SEM). The filiform antennae of A. maritima were of the conventional type comprising a basal scape, pedicle and a long, thread-like flagellum, which was composed of 12 flagellomeres of males and 16 flagellomeres of females. Six morphologically unique sensillar types were found and described on the antennae of males and females of A. maritima. Of those identified, there were three types of porous trichoid sensilla (long, curved and arcuate), and two types of basiconic sensilla (short and curved), and one type of aporous trichoid sensilla. The shape, external morphology and array of sensilla on the antennae of males and females of A. maritima were similar.

The harvested eggs of Rhynchophorus ferrugineus are ovo-cylindrical shaped, averaged 1.09 mm in length and 0.43 mm in width, with ratio of LW 4.42. The chorionic layer of electron dense material is seen covering the exochorion structure of the eggs. The egg main body chorion exhibits a polygonal pattern and architecture surface of the egg is supported by a system of irregular interconnecting grooves. The micropylar apparatus of the eggs of the Red Palm Weevil, R. ferrugineus is described in the present study for the first time. Two micropylar openings are found closed to the center of the posterior wide pole of the egg. Each micropylar opening presents a single small orifice and its surrounding chorion is porous and densely set with tiny projections allowing the spermatozoa to penetrate the egg. Respiratory aeropyles are distributed on the borders of reticulations in the area chorionic surface of egg capsule. The hatching region is detected on the anterior part at the opposite side of the egg. Changes in the appearance and shape of R. ferrugineus eggs as well as the incidence of embryonic development are observed.

The red palm weevil (RPW) is a major pest of palms. It is native to southeast Asia and Melanesia, but in recent decades has vastly expanded its range as the result of multiple accidental anthropogenic introductions into the Middle East, Mediterranean Basin, Caribbean, and U.S.A. Currently regarded as a single species, Rhynchophorus ferrugineus (Olivier), RPW displays remarkable color variation across its range, and consequently has a taxonomic history littered with new species descriptions and synonymization. We compared DNA sequences of the mitochondrial cytochrome oxidase subunit I (COI) gene from RPW populations throughout the native and invaded ranges, to investigate the specific status and invasion history of this serious economic pest, and to identify possible common routes of entry. Analyses of COI haplotype data provide conclusive support, corroborated by sequences of additional nuclear gene regions, for the existence of at least two predominantly allopatric species. The true R. ferrugineus is native only to the northern and western parts of continental southeast Asia, Sri Lanka and the Philippines, and is responsible for almost all invasive populations worldwide. In contrast, the second species, which is currently synonymized under R. ferrugineus and should be resurrected under the name R. vulneratus (Panzer)...

This study deals with the analysis of the integument of the red palm weevil Rhynchophorus ferrugineus of both sexes using the GC–MS technique. The results of the study revealed many promising compounds. These include aspidofractinine-3-methanol (kopsinyl alcohol) which was found in the acetone extract of the sternum of females, and 3-buten-2-ol (32-B) which was found in the extracts of sternum and tergum of males. This compound the aggregation pheromone was secreted by males. Additionally, compounds with methoxy groups were found. These may be responsible for insects’ resistance. This study, through separation and identification of these compounds, aims to open a new possibility for their future medical and therapeutic usage.

The intestinal microbes residing in the red palm weevil (RPW, Rhynchophorus ferrugineus) larva consume tender interior fibrous tissues of date palm trunks. The understanding of such microbiota at molecular level provides vital clues for the biological control of this devastating pest. Using pyrosequencing and shotgun strategy, we first study taxonomic profiles of the microbiota sampled at different months (March, July and November), and then confirm the impact of high-temperature stress on the microbial populations based on data from 16S rRNA amplicons using both field and laboratory samples. We further identify Klebsiella pneumoniae in November and Lactococcus lactis in July as the dominant species of the microbiota. We find that the RPW gut microbiota degrades polysaccharides and sucrose with hydrolases and that different active bacterial species in November and July are responsible for the symbiotic relationship between the microbiota and the host. Our results provide vital information for pest control and cellulolytic bacterial species characterization.

Rhynchophorus ferrugineus, also known as the red palm weevil, is regarded as the major pest of palm trees. Although studies of the microbiota associated with this species have been performed in recent years, little attention has been dedicated to the influence of the diet in shaping the host bacterial community. Here, we investigated the influence of food sources (i.e. palm tissues vs apple based substrate) on the microbial diversity associated with RPW, which was compared with the microbiota associated with wild individuals of the sister species Rhynchophorus vulneratus. The bacterial characterization was performed using a culture independent approach, i.e. the 16S rRNA pyrotag, and a culture dependent approach for a subset of the samples, in order to obtain bacterial isolates from RPW tissues. The bacterial community appeared significantly influenced by diet. Proteobacteria resulted to be the most abundant clade and was present in all the specimens of the three examined weevil groups. Within Proteobacteria, Enterobacteriaceae were identified in all the organs analysed, including hemolymph and reproductive organs. The apple-fed RPWs and the wild R. vulneratus showed a second dominant taxon within Firmicutes that was scarcely present in the microbiota associated with palm-fed RPWs. A comparative analysis on the bacteria associated with the palm tissues highlighted that 12 bacterial genera out of the 13 identified in the plant tissues were also present in weevils...

A state of the art proteomic methodology using Matrix Assisted Laser Desorption/Ionization-Time of Flight (MALDI TOF) has been employed to characterize peptides modulated in the date palm stem subsequent to infestation with red palm weevil (RPW). Our analyses revealed 32 differentially expressed peptides associated with RPW infestation in date palm stem. To identify RPW infestation associated peptides (I), artificially wounded plants (W) were used as additional control beside uninfested plants, a conventional control (C). A constant unique pattern of differential expression in infested (I), wounded (W) stem samples compared to control (C) was observed. The upregulated proteins showed relative fold intensity in order of I > W and downregulated spots trend as W > I, a quite interesting pattern. This study also reveals that artificially wounding of date palm stem affects almost the same proteins as infestation; however, relative intensity is quite lower than in infested samples both in up and downregulated spots. All 32 differentially expressed spots were subjected to MALDI-TOF analysis for their identification and we were able to match 21 proteins in the already existing databases. Relatively significant modulated expression pattern of a number of peptides in infested plants predicts the possibility of developing a quick and reliable molecular methodology for detecting plants infested with date palm.

The incidence of red ring disease was found to be highly correlated with the seasonal abundance of the palm weevil, Rhynchophorus palmarum (L.) Adult insects became contaminated with fragments of diseased tissue containing large numbers of nematodes after visiting diseased palms. The main source of contamination appeared to be the frass in tunnels excavated by the larvae during feeding, but adult weevils also became contaminated by bodily contact with diseased tissue and after walking through suspensions of worms in “pockets” in diseased palms. Internal contamination of the gut and body cavity also occurred following the feeding of insects on infected tissue. Virgin insects were found to be contaminated both externally and internally prior to emergence from their cocoons. The numbers of nematodes picked up by adult weevils was found to vary with the source of contamination, the density, stage, and activity of the worms present, and the age and feeding history of the insect. Longevity of the nematodes on the body surface of the insect varied between 2-6 days and was as long as 10 days in the gut and body cavity. External and internal contamination of the field population was found to be 38.5% and 9.8%, respectively. The incidence of red ring disease was significantly reduced following the application of endrin for palm weevil control.

In tropical America, Rhynchophorus palmarum (L.) is a major pest of coconut, Cocos nucifera (L.), and oil palm, Elaeis guineensis Jacq., through direct attack and as a vector of the red ring nematode, Bursaphelenchus cocophilus Baujard. We have developed an effective trap for this large weevil that employs the newly identified major component of the male-produced aggregation pheromone, 2-methyl-5(E)-hepten-4-ol (rhynchophorol). Trap design, color, placement, and pheromone release rate as well as type, quantity, and longevity of attractiveness of food additives were studied in a commercial oil palm plantation in Costa Rica. Insecticide-treated palm stem pieces baited with rhynchophorol were effective, but buckets or bags with rhynchophorol and insecticide treated sugarcane were the most effective traps. The latter captured 6 to 30 times more weevils than bucket traps containing rhynchophorol or treated sugarcane alone. Trap color did not influence capture rates. More weevils were captured in bucket traps placed at ground level than at 1.7 or 3.1 m. In bucket traps halved sugarcane stalk was significantly more effective than palm pieces, molasses on a sponge, or processed palm mesocarp. Insecticide-treated sugarcane was attractive for 2 wk.

Los m??ltiples usos derivados de ??sta han fortalecido su permanencia, a la vez que la imagen identitaria con que se asocia al territorio. Su presencia ha quedado plasmada en escritos de todo tipo desde la Ilustraci??n hasta nuestros d??as, lo que permite contrastar la visi??n de entonces con la situaci??n que atraviesa en la actualidad. Para ello se analizan tres ??mbitos diferentes, San Isidro, una poblaci??n entre palmeras tras la colonizaci??n de suelos salinos; el Palmeral de Orihuela, como pervivencia de un enclave hist??rico ligado a los rendimientos mixtos de la tierra; y finalmente, la dispersi??n generalizada de la palmera por el medio agrario.; The palm tree, regarded as an agrarian resource, has been closely linked to the orchards, or spaces of "Huerta", developed over centuries in the Segura River fertile plains.

The red palm weevil, Rhynchophorus ferrugineus (Olivier) (Curculionidae: Coleoptera), is not native to the United Arab Emirates (UAE). Since its arrival in 1985, it has been causing major damage to date palm trees. A primary control strategy has been the use of pheromone baited traps. The objectives of this study were to determine the quantity of bait, and the best trap color, to obtain the maximum catch of R. ferrugineus under field conditions in the UAE. Traps with 100, 300, or 500 g of dates as bait collected the same number of R. ferrugineus adults. Captures in black traps were significantly higher than captures in red, yellow, or white traps. Thus, using a black pheromone trap containing 100 g of dates can significantly enhance R. ferrugineus control efforts, and can help considerably in reducing the red palm weevil's deleterious impact on date palm production in UAE.

Il Punteruolo rosso delle palme, Rhynchophorus ferrugineus, Olivier (Curculionoidea, Dryophtoridae), è un coleottero originario del Sud-Est asiatico e della Melanesia invasivo in Medio Oriente ed in quasi tutti i paesi del bacino del Mediterraneo, compresa l'Italia. Il fitofago arreca ingenti danni a numerose specie di Arecaceae, tra cui molte palme di interesse economico. Le attuali azioni di controllo integrato, adottate per contenerne l'espansione, si sono rivelate finora insufficienti anche perché manca una approfondita conoscenza del sistema nuziale dell'insetto, ed il suo grande successo riproduttivo è proprio una delle cause principali del enorme potenziale invasivo di questa specie dannosa. Obiettivo generale del progetto di dottorato è stato dunque lo studio di aspetti del mating system del Punteruolo rosso legati ad eventuali comportamenti poliandrici e fenomeni di selezione sessuale post-copulatoria. Sono stati eseguiti a questo scopo dei test di paternità, per mezzo di analisi genetiche e bioinformatiche, sulla prole di esperimenti di incrocio effettuati in laboratorio, in modo da verificare ipotesi alternative riguardanti il sistema nuziale della specie. Date le scarse informazioni genetiche disponibili su R. ferrugineus...
