INRAE 08/04/21 Découverte d’une cible pour le biocontrôle du charançon rouge du palmier. Le charançon rouge du palmier, Rhynchophorus ferrugineus, est l’ennemi numéro un des palmiers à travers le monde, causant chaque année la perte de millions d’euros.

INRAE 08/04/21 Découverte d’une cible pour le biocontrôle du charançon rouge du palmier

Au cours des deux dernières décennies, cet insecte a dévasté le palmier dattier en Arabie Saoudite, et on estime que ce ravageur menace environ 6 millions de palmiers dans ce pays. Il est présent dans tous les pays d’Asie, d’Europe du Sud, d’Australie et d’Afrique du Nord. Cet insecte évolue au travers de différentes étapes, dans le microhabitat qu’est le stipe des palmiers, et colonise les palmeraies grâce à une communication chimique sophistiquée incluant un bouquet odorant : la phéromone d’agrégation. Ce signal attire les charançons et facilite ainsi l'orientation vers les palmiers, la colonisation et l'accouplement.

(El Husseini et al. 2008) was cultured on potato dextrose agar (PDA) medium poured into sterilized Petri-dishes (12 cm in diameter). Inoculated Petri-dishes with a spore suspension of B. bassiana were incubated for 15 days at 25 °C. The produced areal conidiospores were harvested from the Petri-dishes by scraping with a spatula and suspended in distilled sterilized water with 0.02% Tween 80 as a wetting agent in the primary stock suspension, following Rombach et al. (1987). The spore count was determined by using a Neubauer Hemocytometer, and the stock was kept in the refrigerator till needed. Larvae and adults of RPW Larvae of the RPW were collected from three highly infested date palm trees that suddenly fell on the ground at the Experiment Station at the Faculty of Agriculture, Giza, Egypt, in 2017.

PLOS 19/07/18 Resistance to commonly used insecticides and phosphine fumigant in red palm weevil, Rhynchophorus ferrugineus (Olivier) in Pakistan

This paper reports the first survey of insecticide resistance in field populations of R. ferrugineus in Pakistan which were collected from seven date palm growing areas across Punjab and Khyber Pakhtunkhwa (KPK) provinces, Pakistan. The resistance was assessed by the diet incorporation method against the formulated commonly used chemical insecticides profenophos, imidacloprid, chlorpyrifos, cypermethrin, deltamethrin, spinosad, lambda-cyhalothrin and a fumigant phosphine. Elevated levels of resistance were recorded for cypermethrin, deltamethrin and phosphine after a long history of insecticide use in Pakistan. FRONT. MICROBIOL. 21/11/17 The Gut Entomotype of Red Palm Weevil Rhynchophorus ferrugineus Olivier (Coleoptera: Dryophthoridae) and Their Effect on Host Nutrition Metabolism. Introduction Rhynchophorus ferrugineus, also known as the red palm weevil (RPW), is widely considered as the most devastating insect pest of palms in the world, even in the countries where it has been accidently introduced (Ju et al., 2011; Hou et al., 2011; Wan et al., 2015).

FRONT. MICROBIOL. 21/11/17 The Gut Entomotype of Red Palm Weevil Rhynchophorus ferrugineus Olivier (Coleoptera: Dryophthoridae) and Their Effect on Host Nutrition Metabolism

This weevil is native to southern Asia and Melanesia, but due to international exchange of infected plant materials, it has spread to the Middle East, Africa and the Mediterranean Basin. More recently, RPW has become established in China, Japan, Australia and the Caribbean (Zhang et al., 2003; Wang et al., 2015).

Kesavan Subaharan, N Bakthavatsalam, Vibina Venugopal Abstract Red palm weevil (RPW) has been a devastating pest of the palms. Originally a pest of coconut palm in India, it has spread across to various hosts. Mortality caused to host by its damage has caused RPW to gain pest of national interest in many countries.

Des mesures visant à lutter contre le charançon rouge du palmier ont été prises en Tunisie. 29 mars 2017, Rome - Un petit charançon rouge détruisant les palmiers s'est rapidement répandu à travers le monde et menace la production de dattes et de noix de coco, si rien n'est fait pour l'en empêcher.

FAO 29/03/17 Premier effort mondial pour empêcher le charançon rouge de détruire les palmiers

Des scientifiques, des spécialistes de la lutte contre le ravageur, des ministres de l'agriculture et des représentants agricoles ont débuté une réunion de trois jours à l'Organisation des Nations Unies pour l'alimentation et l'agriculture (FAO), à Rome, dont l'objectif est de définir un plan d'action international visant à empêcher la progression du charançon rouge du palmier. Le ravageur s'attaque aux palmiers dattiers, aux cocotiers, ainsi qu'aux palmiers d'ornement que l'on peut voir dans de nombreuses villes européennes.

The red palm weevil (RPW), Rhynchophorus ferrugineus Olivier is an invasive, hidden pest of date palms causing significant economic losses in Middle East.

AFRICAN JOURNAL OF AGRICULTURAL RESEARCH 24/03/16 Efficiency of optimal pheromone trap density in management of red palm weevil, Rhynchophorus ferrugineus Olivier

Mass trapping of weevils with synthetic male aggregation pheromone and food baited traps has been an important component of Integrated Pest Management (IPM) program against RPW. As the viability of pheromone trapping system depends on the optimum trapping density, field experiments were conducted in two locations of Eastern Province of Saudi Arabia. The efficiency of four pheromone trap densities viz., 1, 2, 4 and 8 traps/4 ha, were evaluated using the Standard Saudi Trap. In Al Hassa experiment, the treatment with 1 trap / 4ha captured an average 10.0 weevils as compared to 61.5 weevils in 8 traps / 4 ha, while at Al Qatif experiment an average of 5.0 and 49.8 weevils were captured in 1 trap and 8 traps / 4 ha respectively in 10 weeks indicating the superiority of high density trapping.

The red palm weevil, Rhynchophorus ferrugineus, is a species of snout beetle also known as the Asian palm weevil or sago palm weevil. The adult beetles are relatively large, ranging between two and five centimeters long, and are usually a rusty red colour - but many colour variants exist and have often been misidentified as different species (e.g., Rhynchophorus vulneratus;[2]). Weevil larvae can excavate holes in the trunk of a palm trees up to a metre long, thereby weakening and eventually killing the host plant. As a result, the weevil is considered a major pest in palm plantations, including the coconut palm, date palm and oil palm.[3] Originally from tropical Asia, the red palm weevil has spread to Africa and Europe, reaching the Mediterranean in the 1980s.

It was first recorded in Spain in 1994,[4] and in France in 2006. Life cycle[edit] Oviposition[edit] After fertilization, the adult female can lay between 300 and 500 eggs.

L’adulte est un charançon de 2 à 4 cm de long, doté d’un long rostre, au corps orangé vif avec des taches noires. Il vole surtout de jour entre 25 et 40°C. Les femelles pondent toute leur vie entre 100 et 300 oeufs. La larve, qui mesure au maximum 5 cm de long, est le stade nuisible.
