“…The Red Palm Weevil (RPW) Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae) is a key pest of palms that has expanded its geographical and host range during the last three decades, ever since it gained foot hold on date palm Phoenix dactylifera L. in the Middle-East during the mid-19980s (Faleiro, 2006;Giblin-Davis et al, 2013;Gomez and Ferry, 2002). Rhynchophorus palm weevils threaten agricultural areas and natural landscapes (Milosavljević et al, 2018) and RPW poses a major threat to palm species in diverse agro-ecosystems worldwide. Recently the Caucuses (Sochi in Russia and Abkhazia in Georgia- Faleiro, 2018) and East Africa (Djibouti: Personal communication from Mr. Yusuf Duhur on 16 June, 2018) have detected RPW on the Canary palm and date palm, respectively.…”

The Red Palm Weevil (RPW) Rhynchophorus ferrugineus Olivier has emerged as a key pest of palms in diverse agro-ecosystems worldwide. RPW has its home in South and SouthEast Asia where it has been a major pest of coconut. Ever since it was reported on date palm in the Middle East during the mid-1980s, it has spread rapidly mainly through infested planting material. Recent reports of RPW invasion suggest that the pest is gaining foot hold in the Caucasian region where it is detected from Sochi in Russia and Abkhazia in the republic of Georgia and also from East Africa in Djibouti. The current RPW IPM programmes, based on pheromone/bait trapping among other techniques have been implemented with limited success. Gaps and challenges in almost all the components of the strategy, particularly with regard to early detection of the pest, developing and implementing phytosanitary measures, lack of farmer participation in the programmes and scarcity of data on socioeconomic issues among several other factors have made RPW control and eradication extremely difficult. On the positive side, the pest has been eradicated in the Canary Islands and is approaching eradication in Mauritania. Eradication has also been obtained in various oasis in Oman but new introductions of infested palms have ruined these successes. The Food and Agriculture Organization of the UN during the Scientific and High Level Meeting on the Management of RPW in March, 2017 called for the urgent need to combat RPW by collaborative efforts and commitments at the country, regional and global levels to stop the spread of this devastating pest and formulated a framework strategy for eradication of RPW which aims to support efforts/programs of countries to stop its spread, to achieve a strong decline and if possible its eradication. This has led to the 'FAO Programme on RPW Eradication in the NENA Region' to intensify governance, monitoring, scientific research, capacity building and coordination. The program fosters the ongoing research on the applicable approaches of biological control and innovative detection and control methods. Furthermore, the 'FAO Global RPW management platform' aims mainly at monitoring the pest using mobile apps and GIS based techniques. This presentation highlights the gaps and challenges in the current RPW-IPM strategy with prospects for improving each component of the RPW-IPM program, based on a much better knowledge on the socioeconomic situation and the participation of the farmers and other stakeholders.

“…Most recent introductions of RPW are from Abkhazia in the Republic of Georgia and in Djibouti in East Africa (Faleiro et al, 2018). Palm weevils threaten agricultural (date plantations) and natural areas (palm oases) (Milosavljević, 2018).…”

“…Insecticide applications are, at present, the most effective method for protecting palms from attack by palm weevils (Milosavljević, 2018). Although, curative treatments of RPW infested date palms using aluminium phosphide is widely practiced in UAE and the state of Bahrain, there is no information on the dose and duration of treatment using aluminium phosphide to safely and effectively treat RPW infested date palms.…”

Al Ballaa S.R. and J.R. Faleiro. 2019. Studies on curative treatment of red palm weevil, Rhynchophorus ferrugineus Olivier infested date palms based on an innovative fumigation technique. Arab Journal of Plant Protection, 37(2): 119-123. The Red Palm Weevil (RPW) Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae) is a key pest of date palm Phoenix dactylifera L. in the Near East and North Africa region. RPW infested date palms respond to curative chemical treatments if detected and judiciously treated in the early stage of attack. However, the currently used curative treatments, involve either excessive tissue removal of the palm around the infested palm section (mechanical sanitization) making the palm weak and vulnerable to toppling, injecting insecticide into the infested palms which often does not kill all the stages of the pest within the palm, calling for repeated applications or fumigating the infested palm section with phosphine gas which is also not always effective, possibly due to inadequate dose and escape of the gas. A new fumigation technique involving treatment of infested date palms with aluminium phosphide tablets (3g) ensuring complete entrapment of phosphine gas was devised and field tested in 295 RPW infested date palms in various stages of attack in Al-Qassim, Kingdom of Saudi Arabia, during 2017-2018. The technique was tested in both young date palms (9-12 years old) as well in offshoots (4 years old), through a series of field trials to optimize the number of applications, dose, duration of treatment and type of wrapping to entrap the gas. Results revealed that for young date palms in the susceptible age of attack to RPW, a single application of 10 aluminium phosphide tablets for 5 days inserted in air tight black plastic wrapping resulted in complete mortality of larva, pupae and adult stages of the pest. Further, in offshoots, a single treatment with 15 aluminium phosphide tablets inserted in air tight transparent plastic wrapping for 10 days ensured complete mortality of the pest within the palm. The technique can be used for both field treatment of infested palms as well for quarantine treatment of date palm offshoots and is gaining popularity in Saudi Arabia.

BACKGROUND Invasions of a number of tree‐feeding beetles have increased globally and pose a mounting threat to the world's trees, production forests and natural habitats. An in‐depth understanding of the determinants of invasion potential of a given species and invasibility of novel environments can help forecast future invasions and avert undesirable socio‐economic impacts. Here, we quantitatively assess the (multivariate) drivers of historic invasions of the coconut hispid Brontispa longissima (Coleoptera: Chrysomelidae) across the Asia‐Pacific region and critically assess its invasion potential for other key coconut‐growing regions. RESULTS Genetic variation of B. longissima in its invaded range indicated multiple incursions, likely associated with (short‐range) natural dispersal and (long‐range) trade in ornamental palms and coconut plantlets. Interception records at China's ports of entry accentuate the role of traded planting material. The high fecundity and prolonged, yet adaptable, oviposition period of B. longissima further enhance the invasiveness of this species and aid its successful establishment. Coconut‐growing areas are identified with high climatic suitability for B. longissima, and where strengthened biosecurity protocols can prevent future invasions. CONCLUSION A combined assessment of inter‐country trade patterns, population genetics and species bio‐ecology (e.g. climate‐related development) illuminates the dispersal pathways of invasive species, assesses invasibility of particular geographies, guides quarantine interventions and thus can effectively avert future invasions. © 2019 Society of Chemical Industry
