High infestation was reported in Miri, Mukah and Sibu. Censuses on the infestation of T. rufivena were conducted at three different locations, i.e. in Miri (young palm), Mukah (mature palm) and Sibu (ablation samples). Samples for census were taken from infested bunches, female and male inflorescences. The census was done by chopping the bunches and the female inflorescences while for the male inflorescences, the bottom of spikelets were cut to determine the number of live larvae and pupae. The census 44 Serangga reveiled that in Sibu, a high infestation of T. rufivena was found on male inflorescences compared to bunches of female inflorescences. The mean number of live larvae found in male inflorescences for the first and second day of census recorded 35.3 ± 15.7 and 14.0 ± 7.3, respectively. The highest number of live larvae recorded from male inflorescences was 207 and 65, respectively. Meanwhile, the mean number of live larvae from infested bunches and female inflorescences on the first day were 9.9 ± 3.5 and 19.4 ± 4.4, respectively. -
Giant Palm Weevils of the Genus Rhynchophorus (Coleoptera: Curculionidae) and Their Threat to Florida Palms
DACS-P-01719 Pest Alert created 18-February-2010 Florida Department of Agriculture and Consumer Services, Division of Plant Industry Adam H. Putnam, Commissioner of Agriculture Giant Palm Weevils of the Genus Rhynchophorus (Coleoptera: Curculionidae) and Their Threat to Florida Palms Michael C. Thomas, Taxonomic Entomologist, Florida Department of Agriculture and Consumer Services, Division of Plant Industry INTRODUCTION: The giant palm weevils of the genus Rhynchophorus Herbst are among the worst palm pests in the world. One species, Rhynchophorus cruentatus (Fabricius), is native to Florida and the southeastern US. Two other species, Rhynchophorus ferrugineus (Olivier) and Rhynchophorus palmarum (L.), are found in the New World and are considered to be threats to palms in Florida. Of particular concern is R. ferrugineus, known as the red palm weevil. It is a pest of coconut and other palms in its native range. Over the past three decades, its range has expanded into the Middle East, North Africa and Mediterranean Europe. It attacks many palm species, but is especially devastating on date palms. It recently became established in Curaçao in the Caribbean, placing it ever closer to Florida. In each case, it is suspected that the weevils travelled with imported palms. In January 2010, the federal government prohibited the importation into the United States of live palms belonging to 17 genera. IDENTIFICATION: Identification of adult palm weevils is straightforward as they are the largest weevils in NorthAmerica, ranging from about 1 to 1.8 inches (25mm to 45mm) in length. The individual species are rather similar, but the three species under consideration can be distinguished by the following key: 1. -

The Oil Palm Grower's Handbook
Human Planting Soil Material Timing Water Other Tools Plants Light 2 Human Planting Soil Material Timing Water Other Tools Plants Light 3 4 Introduction What drives life is a little electric current, kept up by the sunshine. Albert SZENT-GYÖRGYI, Nobel prize for medicine 1937 5 Over its lifetime, oil palm is one of the crops that generates most current" per unit area, from photosynthesis to oil: 5 to 10 times more oil per hectare than any other oil crop. This energy, in oil form, offers high nutritional value (vitamins, antioxidants, oleic fraction) and technological qualities (the naturally solid fraction is of interest to the agrifood industry). The photosynthetic efficiency of the oil palm cannot be achieved without humans, who are ten times more numerous per unit area than for the production of soybean oil: an “oil palm” project is therefore first and foremost a human project, a job generating project, a project that is demanding in both skills and work quality, a project combining the sun, land and people. These people are actively committed to producing seeds, managing prenurseries, nurseries and plantations, ensuring their upkeep and harvesting them... Their work is well rewarded, even on difficult soils. Water is the “switch”, and even the combustion agent, since every mm of rainfall gained over the water deficit generates much more than a linear response. Solar radiation feeds flow intensity, temperature modulates it. Production is organized in a given space that obviously needs to be preserved, or even enhanced – even more over the long term (oil palm works well for those who persevere best, and rewards them most generously). -

EPPO Categorization: A1 list view more categorizations online... EU Categorization: A1 Quarantine pest (Annex II A) EPPO Code: RHYCPA HOSTS R. palmarum has been reported on at least 35 plant species in at least 12 different families. However, it is primarily found in association with palms (Arecaceae) (Esser & Meredith, 1987; Grif?th, 1987; Wattanapongsiri, 1966; Jaffé & Sánchez, 1990; Sánchez & Cerda, 1993). With respect to palms, R. palmarum is commonly reported as a pest. It has also been observed reproducing on sugarcane stems, a non-palm host, (Arango & Rizo, 1977; Restrepo et al., 1982). Feeding damage by larvae to the apical meristematic region (i.e. the palm heart) causes palm mortality (Milosavljevi? et al., 2019). When reported on other plants, R. palmarum adults were observed feeding on ripe fruit. This type of feeding on fruit by adult weevils is typically not a source of significant economic damage. Breeding hosts: R. palmarum breeding is primarily restricted to palms (Arecaceae) and known hosts include: Brahea edulis (Guadalupe palm), Cocos nucifera (coconut), Dypsis lutescens (golden cane palm), Elaeis guineensis (African oil palm), Euterpe edulis (juçara, grown for hearts of palm), Livistona australis (cabbage tree palm), Metroxylon sagu (true sago palm), Phoenix canariensis (Canary Islands date palm), P. -

Improving Nutrient Use Efficiency. Turkish Journal of Agriculture and Forestry, 32:177-182. Reference ID: 21904 Notes: #21904e Abstract: Public interest and awareness of the need for improving nutrient use efficiency is great, but nutrient use efficiency is easily misunderstood. Four indices of nutrient use efficiency are reviewed and an example of different applications of the terminology show that the same data set might be used to calculate a fertilizer N efficiency of 21% or 100%. Fertilizer N recovery efficiencies from researcher managed experiments for major grain crops range from 46% to 65%, compared to on-farm N recovery efficiencies of 20% to 40%. Fertilizer use efficiency can be optimized by fertilizer best management practices that apply nutrients at the right rate, time, and place. The highest nutrient use efficiency always occurs at the lower parts of the yield response curve, where fertilizer inputs are lowest, but effectiveness of fertilizers in increasing crop yields and optimizing farmer profitability should not be sacrificed for the sake of efficiency alone. There must be a balance between optimal nutrient use efficiency and optimal crop productivity. Souza L. F. D.and D. H. Reinhardt. 2015. Pineapple. Pages 179-201 IPO.

Bud Rot and Other Major Diseases of Coconut, a Potential Threat to Oil Palm

The best-known examples are animal and/or human pathogens. Reference will briefly be made to them as they are very concrete examples of the current epidemic context. However, this also applies for the spread of plant diseases that we have been witness to in the last thirty years. Not only do pathogens travel over long distances, they also “jump hosts”, be it in the Animal Kingdom or the Plant Kingdom. Climate changes may be conducive to such events. Using these data, we shall attempt to examine the possible risks of seeing pathogens of the coconut palm, Cocos nucifera, or even of other plants, attacking the oil palm, Elaeis guineensis. DISPERSAL/PROPAGATION OF ANIMAL AND HUMAN PATHOGENS Sars The first example involves SARS (Severe Acute Respiratory Syndrome) which was identified in humans in China at the end of 2002. At the beginning of 2003, a hotel in Hong Kong very close to the original focus was the starting point for an epidemic that affected Vietnam, Singapore and even Toronto in Canada within a few weeks. -

Abstract Palm production faces serious challenges ranging from diseases to damage by insect pests, all of which may reduce productivity by as much as 30%. A number of disorders of unknown aetiology but associated with insects are now recognised. Management practices that ensure the sustainability of palm production systems require a sound understanding of the interactions between biological systems and palms. This paper discusses insect pests that attack palms, pathogens the insects vector as well as other disorders that are associated with these pests. We re-examine the disease aetiologies and procedures that have been used to understand causality. Pest management approaches such as cultural and biological control are discussed. Key words aetiology, Arecaceae, diagnosis, pathosystems, pest management. INTRODUCTION has transported them from their native habitats to new loca- tions. For example, the date palm is believed to have originated In many cultures, palms are a symbol of splendour, peace, in the Persian Gulf and North Africa but it is now grown victory and fertility. Palms constitute one of the best-known worldwide in semi-arid regions (Zaid 1999).
