The red palm weevil, Rhynchophorus ferrugineus (Olivier) (Coleoptera, Curculionidae), is a widely distributed pest which has recently become the major pest of palms in the Mediterranean Basin. This weevil has been recorded on 19 different palm species, however, the host status of Washingtonia filifera and Chamaerops humilis remains unclear. The present study was carried out to check whether these species had either antixenotic or antibiotic mechanisms of resistance against this pest. Our… 

ATTACKS OF RHYNCHOPHORUS FERRUGINEUS (OLIVIER) (Coleoptera Curculionidae ) ON NATURAL SPECIMENS OF DWARF FAN PALM CHAMAEROPS HUMILIS L. ( Arecaceae ) IN SICILY

Reports of attacks of R. ferrugineus on dwarf fan palms in natural environments of Sicily indicate that this insect represents an important threat to dwarf palms and to the complex ecosystem where they live.

Susceptibility and possible resistance mechanisms in the palm species Phoenix dactylifera, Chamaerops humilis and Washingtonia filifera against Rhynchophorus ferrugineus (Olivier, 1790) (Coleoptera: Curculionidae)

It is concluded that the observed lack of infestation of P. dactylifera by RPW is due to factors other than antibiosis, and resistance to R. ferrugineus seems to rely on the presence of antibiosis compounds.

Factors influencing the mobility of Red Palm Weevil Rhynchophorus ferrugineus (Coleoptera: Dryophthoridae) adults.

The chromatic preference of R. ferrugineus adults has been studied by analysing their captures in coloured bucket traps, and the influence of sex, body size, and age of the adults on the aforementioned parameters has been examined.

Short communication. Susceptibility of Phoenix theophrasti (Palmae: Coryphoideae) to Rhynchophorus ferrugineus (Coleoptera: Curculionidae) and its control using Steinernema carpocapsae in a chitosan formulation

Gummy secretion was observed in both naturally and forced infested palms indicating the existence of antibiosis in this species, and curative applications with the entomopathogenic nematode Steinernema carpocapsae in a chitosan formulation in early infested P. theophrasti palms managed to reduce insect’s activity and could help the palms to recover.

Can high pest pressure of the red palm weevil Rhynchophorus ferrugineus beat the defense of Phoenix theophrasti?

Summary The Cretan date palm, Phoenix theophrasti, is a less susceptible and suitable host for the red palm weevil compared to the Canary palm, P. canariensis, even at high pest pressure.

Comparative Susceptibilities of Different Life Stages of the Red Palm Weevil (Coleoptera: Curculionidae) Treated by Entomopathogenic Nematodes

There is a great potential for the use of EPNs, in particular the Steinernema sp.

Could Plant Hormones Provide a Reliable Tool for Early Detection of Rhynchophorus ferrugineus (Coleoptera: Curculionidae) Infested Palms?

The main objective has been to characterize the metabolic response of Phoenix canariensis hort to identify candidate biomarkers for early detection of R. ferrugineus injury and to exploit these substances as early warning signs of infestation.

A QUARANTINE PROTOCOL AGAINST RED PALM WEEVIL RHYNCHOPHORUS FERRUGINEUS (OLIVIER) (COLEPTERA: CURCULIONDAE) IN DATE PALM

It is recommended to dip date palm offshoots in 0.004% Fipronil for 30 min before transporting to ensure complete mortality of the hidden larval stages, if any and complete certification and transport of the treated offshooting to the new planting site within 72 h of treatment.

Biology and Management of Red Palm Weevil

An urgent need to develop and deploy tools for early detection of infested palms, enhance the knowledge of the relationships between R. ferrugineus and its hosts, and explore alternatives to synthetic organic insecticides for eco-friendly management of this insect pest.

Antixenosis–A New Term Proposed to Define Painter's “Nonpreference” Modality of Resistance

Reginald Painter proposed that plant resistance, as observed in the field, could be explained by three fundamental mechanisms which he named: (a) nonpreference, (b) antibiosis, and (c) tolerance.

El unico efecto encontrado, debido a the cria prolongada en laboratorio, fue el menor tamano of las hembras adultas, que fue mas acusado en el caso of los machos; sin embargo, el mismo no repercutio en los parametros biologicos, antes indicados.
