Abstract:
Coconut is inseparable part of life of people of southern India particularly in the states of Kerala and Tamilnadu. Coconut as tender coconut water, coconut gratings, coconut milk, coconut oil etc. find its way in at least one food item cooked daily the people of this southern part of India. Due to extreme shortage in people to climb the coconut trees and pluck the coconuts, the cost of coconuts is increasing steeply. One solution to this problem is to have a robotic coconut tree climber with an arm to cut the coconuts. In this research work, we present the design, implementation and testing of robotic arms to be used in these robotic coconut tree climbers, to cut the coconuts. Different robotic arm designs are presented with proper analysis and results.

Abstract:
Endosperm quantity in kopyor coconut determines the quality of kopyor coconut. However, data of the best parental based on their progeny test is unavailable yet. In this study, we employed polycross approach and SSR molecular marker to estimate general combining ability of the best pollen contributor for the breeding purpose of this trait. Totally 151 kopyor coconuts were collected from the naturally open-pollinated population of kopyor Tall coconut Agom Lampung. The harvested nuts were rated for their endosperm quantity (scored 1-9). The analysis identified 31 paternal trees of the 53 progenies. The TJ-185 with the highest GCA has been considered as a promising paternal tree for development of high endosperm quantity of kopyor coconut.Keywords: combining ability, molecular marker, paternal trees, polycross, tall coconut

Abstract:
Coconuts (Cocos nucifera) have been grown in Coastal Kenya for many centuries and are an integral part of the farming systems in the region. Over 80% of the coastal farm households derive their livelihoods either directly or indirectly from the coconut tree that is considered as both cash and a food crop. The coconut tree on the other hand has a tremendous potential of helping Kenya’s poor in the coastal region and the rest of the country due to its multi-purpose uses that can be strategically harnessed to generate employment and income, reduce edible oil imports and generate foreign exchange for the country. The tree population stands at 7.5 million palms. Nut production is however very low (a minimum of 30 nuts per tree per year) owing to a number of challenges that include high incidences of pests and diseases, poor agronomic practices, low quality planting materials and a narrow genetic base. In order to address the major challenge of coconut pests, a baseline survey was undertaken in the major coconut producing counties of coastal lowland Kenya, targeting the smallholder coconut farmers. A total 170 farmers were interviewed using a structured questionnaire. A literature review was also conducted to contextualize and benchmark findings of the survey. Results showed that the rhinoceros beetle was the major pest on coconut trees, causing damage of up to 80% of the palms. The Coreid bug (Pseudotheraptus wayi) and the Eriophyid mites (Aceria guerreronis) were the major nut destructive pests with a resultant nut loss of 30% and 40% respectively. The study stresses the need to address the challenges posed by pests and diseases on coconut by adopting the Integrated Pest and Disease Management (IPDM) practices.

Abstract:
A study was conducted to analyze community perception on homestead agro-biodiversity and conservation of coconut genetic resources at Bagharpara Upazila (Sub district) of Jashore district, Bangladesh in October 2011. Tools and techniques of Participatory Rural Appraisals (PRA) were utilized to identify the socio-economic factors and agronomic practices influencing homestead agro-biodiversity. The participants identified coconut as a leading species in the homesteads. Communities suspected that the wave (electro-magnetic) generating from mobile phone towers was the cause of damaging coconut in their villages. Being disheartened with continuous yield loss, the farmers have resorted to fell down their coconut trees and shifted to cultivating fruit trees or suitable field crops. The research team used the matrices of PRA to develop a problem tree, which marked mite infestation in coconut as the focal problem. The developed problem-tree was transposed into an objective tree. Based on the objective tree, the research team was able to develop and implement a three-year research project on mite management in coconut involving farmers as implementers. The intervention stimulated community knowledge and skills towards mite management and conservation of unique traditional coconut varieties.

Abstract:
The coconut is known as Kalpa Vriksa to the world for being its multi faceted uses, which provide livelihood security to millions of people. Every part of it useful to humans in one of the other ways. The coconut palm is grown in more than 93 countries of the tropics. Its botanical name is Cocos-Nucifera L. and belongs to the aracaceae (Palm) family. The climbing methods of coconuts like manual, mechanical and climbing by Tractor Operated Hydraulic Elevator (TOME) were studied. The stability, safety, harvesting efficiency, drudgery of coconut harvesting is reduced by Tractor Mounted and Self Propelled Coconut Climber (TMSPCC) developed by considering the drawbacks of the above methods. The testing of developed TMSPCC was carried out at a Coconut Research Station, Bhyte Ratnagiri, India. To assess the physiological cost and the drudgery involved in the traditional method of tree climbing operation. The digital polar hart rate meter RS400TM having infrared connectivity sensor was used for recording the heart rates. The technical assessments included the use of biomechanical models, ODR, BPDS. The ergonomical evaluation of TMSPCC was carried out for testing feasibility, ease of operation; workers jeopardize safety health and efficiency for coconut harvesting. Ergonomically operational safe and controlled heart rates are recorded. The fourteen to seventeen number of coconut orchards were harvested in one hour by using TMSPCC. The tractor mounted and self propelled coconut climber founds suitable for harvesting 100 to 120 coconut trees in a day. The net coconut harvesting by using TMSPCC are 4000 coconuts/day. Also TMSPCC is safe, less hazardous and economical as compared to manual climbing coconut harvesting and climbing by the existing tractor mounted hydraulic elevator.

Abstract:
Coconut palm (Cocos nucifera L.) is one of the most important oil crops in the tropics. The tree is able to grow well under saline intrusion condition. However, in the case of high level of salinity for a long period, the coconut tree is severely affected, resulting in poor growth and yield. Therefore, providing balance and sufficient nutrients would help plants tolerate better to unsuitable environment including salinity. Among plant macronutrients, phosphorus is considered to help coconut tree have more roots and leaves, stimulating flowers formation and fruit setting which lead to improve yields. The aim of this work was to determine effects of the amount of phosphorus fertilizer and the frequency of application on growth, yield and quality of coconut tree at early reproductive stage under saline intrusion condition. Two two-factor experiments were conducted in Binh Dai district, Ben Tre province and Tan Phu Dong district, Tien Giang province where the highest salinity in the dry season reached 13.8‰ and 6.3‰, respectively. The treatments of experiments were arranged in split-plot design (SPD) with three replications. The main plot factor was the frequency of phosphorus fertilizer application (2 and 4 times per year) and the sub-plot factor was the amount of phosphorus fertilizer (30, 45, 60 and 75 kg P2O5/ha/year). The results showed that coconut trees grew best with the treatment of four applications of 60 kg P2O5/ha/year, corresponding to 0.3 kg P2O5/tree/year. The trees in this treatment had more leaves, fruit setting, nut number per tree and higher yield than other treatments under saline intrusion condition.

Abstract:
In the late 90s coconut farms in Mozambique were affected by a disease that made the coconut trees drop their leaves and die, the disease is called the coconut lethal yellowing disease (CLYD). It is known that planthoppers are spreading the disease. This thesis investigates if cultivation and farm related factors could have an impact on the risk of being infected by CLYD. With a sample of 534 farms from the two provinces Zambeze and Nampula a logistic regression model is estimated. The result shows that the only factor that has a significant effect of increasing the risk of getting infected by the disease is if farms had other palm species than coconut trees on the plantation.
I slutet av 90-talet drabbades många kokosnötsfarmer i Mocambique av en sjukdom som gjorde att träden började tappa sina löv och till slut dog. Denna sjukdom kallas för ”the coconut lethal yellowing disease” (CLYD). I dagsläget vet man att det är en specifik insekt som sprider denna sjukdom. Denna uppsats undersöker om det finns andra faktorer som kan påverka risken för koksnötsfarmer att drabbas av denna sjukdom, faktorer som är kopplade till farmerna och dess vegetation. Genom ett urval av 534 farmer från de två provinserna Zambezia och Nampula skattades en logistik regression. Resultatet visade att det enbart är en faktor, om plantagen innehåller andra palmsorter, som signifikant ökar risken för att en farm ska drabbas av CLYD.

Abstract:
Coconuts are one of the most economically important plants in Mozambique, where millions of people depend on income from coconuts. The coconut lethal yellowing disease (CLYD) is a highly destructive disease that ever since the early 90’s causes coconut palms in Mozambique to stop producing fruit and leave the coconut farmers with only empty stems. This thesis examines the disease's effect on the farmers’ income, both from coconuts and other complementary sources, since the vendible harvest should decrease with the incidence of the disease. The method used is multivariate linear regression, where several income variables are used as dependent variables. Two models are created, one only interpreted for the sample of 488 observations and one aiming at generalizing the results. By this study, it cannot be confirmed that the incidence of CLYD has a significant effect on coconut farmers’ income. The results from the sample analysis do however show that the income is affected by the degree of the disease, which is an incentive for continued research in the field.

Esta pesquisa teve como objetivo estudar diferentes possibilidades de redução do volume de água a ser aplicado pela irrigação localizada na cultura do coqueiro anão no semi-árido nordestino, através de um manejo de água, solo e da cultura. Para isto, foram realizadas as seguintes tarefas: testou-se uma nova metodologia de cálculo para o volume de água aplicado na cultura do coqueiro, que considera apenas a área efetiva de maior adensamento do sistema radicular, visando à domesticação de seu desenvolvimento num determinado bulbo molhado; controlou-se a temperatura do solo através da plasticultura, tendo em vistas redução na evaporação d'água no solo e, consequentemente, diminuição no volume d'água a ser aplicado; e avaliou-se o desenvolvimento inicial da cultura do coco, através das variáveis altura de planta e diâmetro do caule, para os procedimentos de manejo de água, solo e da cultura propostos nesta pesquisa. O experimento de campo foi instalado em blocos inteiramente casualizados, resultante de duas combinações fatoriais entre quatro diâmetros molhados (D| = 0,7 m, D2 = 0,8 m, D3 = 0,9 m, D4 = 1,0 m), delimitados por anéis de zinco que possuíam uma altura de 35 cm, sendo 20 cm enterrados no solo, e duas condições de cobertura de solo (coberto e nu), mais uma testemunha (4x2+ 1), perfazendo nove tratamentos com três repetições, totalizando vinte e sete parcelas. Para ambas as condições de cobertura do solo, os diferentes volumes de água aplicados nos diversos diâmetros de influência do sistema radicular não apresentaram efeito significativo no desenvolvimento da cultura do coco, no que diz respeito à sua altura e ao diâmetro caulinar, durante os primeiros 120 dias após transplantio. O procedimento de cálculo do volume de água aplicado promoveu considerável economia de água, com valores máximos e mínimos, respectivamente, de 93,95 e 87,62%, na condição de solo sem cobertura, e de 96,98 e 93,81%, em solo com cobertura. O isolamento da evaporação contribuiu para redução substancial (50%) no volume de água aplicado, ficando demonstrada a importância de se controlar a temperatura do solo em regiões semi-árias e a eficiência do filme de polietileno de duas faces para esta finalidade.
This research had as objective to study different possibilities of reduction of the water volume to be applied by localized irrigation in the dwarfish coconut crop in the Northeast semi-arid region, through a management of water, soil and of the crop. Thus, the following tasks were accomplished: a new calculation methodology was tested for the volume of water applied to the coconut crop, that considers only the effective area of higher concentration of the root system, seeking to the domestication of its development in a certain wetted bulb; the soil temperature was controlled by using plastic manta, purposing the reduction in the soil water evaporation and, consequently, decrease in the volume of water to be applied; and the initial development of the coconut crop was evaluated, through the variables plant height and diameter of the stem, for the water, soil and crop management procedures proposed in this research. The field experiment was installed in entirely randomized blocks, resulting from two factorial combinations between four wetted diameters (Di = 0,7 m, D2 = 0,8 m, D3 = 0,9 m, D4 = 1,0 m), delimited by zinc rings having a height of 35 cm, being 20 cm buried into the soil, and two conditions of soil covering (covered and nude), plus a control (4x2 + 1), resulting in nine treatments with three replications, totaling twenty-seven plots. For both conditions of soil covering, the different applied volumes of water in the several diameters of influence of the root system didn't present significant effect on the development of the coconut crop, regarding its height and stem diameter, during the first 120 days after sowing. The procedure of calculation of the applied volume of water promoted considerable economy of water, with maximum and minimum values, respectively, of 93.95 and 87.62%, in the soil condition without covering, and of 96.98 and 93.81%, in soil with covering. The isolation of the evaporation contributed to substantial reduction (50%) in the applied volume of water, being demonstrated the importance of controlling the soil temperature in semi-arid áreas and the efficiency of the two faces polyethylene film for this purpose.

Plants have evolved various strategies to defend themselves against herbivory. Under herbivore attack, they emit volatile organic compounds that indirectly defend the plant, by attracting herbivore s natural enemies or directly by repelling the herbivore. The coconut tree, Cocus nucifera, is grown in all regions of the country, being predominant in the northeast and hold socio-economic importance for the country. In this sense, the objective of this study was to characterize the emission of volatiles by C. nucifera induced upon herbivory of Brassolis sophorae caterpillars and to assess the behavioral response of Winthemia analis, larval parasitoid of B. sophorae, to B. sophorae induced volatiles. In addition, the biology of W. analis was studied. Were collected, using the aeration process, volatiles emitted by C. nucifera under the following treatments: 1 undamaged plants; 2 mechanically-damaged plants and 3 plants upon herbivory of Brassolis sophorae caterpillars. The collected volatiles were chemically analyzed by gas chromatography coupled to mass spectrometry (GC-MS). The behavioral response of the parasitoid to the induced compounds was tested in a Y-tube olfactometer, and the life cycle was determined from 79 larvae emerged from 28 B. sophorae pupae. The compounds nonanal, decanal and two ketones, geranyl acetone and 6-methyl-5-hepten-2-one, were identified in the samples containing volatiles emitted by C. nucifera 48h after the application of the three treatments. The homoterpene (E)-4-8-dimethyl-1,3,7-nonatriene (DMNT) was identified only in the samples containing volatiles emitted by C. nucifera upon herbivory of Brassolis sophorae caterpillars and mechanically-damaged plants. The DMNT contribution was higher in the sample emitted by plants upon herbivory of Brassolis sophorae caterpillars than in the samples emitted by mechanically-damaged plants. W. analis files were not attracted to the odors emitted by C. nucifera upon herbivory of Brassolis sophorae caterpillars. The emergence rate of adults was about 73%. Were possible to check sexual dimorphism in the adults wings using geometric morphometric (p<0.0001). The morphological analysis of the W. analis adults show one characteristic in the male abdomen.
As plantas apresentam diversas estratégias de defesa contra herbivoria. Muitas plantas, quando atacadas emitem compostos orgânicos voláteis que auxiliam na sua defesa, por meio da atração de inimigos naturais dos herbívoros ou repelindo diretamente o herbívoro. O coqueiro, Cocus nucifera, tem seu cultivo presente em todas as regiões do país, sendo predominante na região nordeste e apresenta uma grande importância social e econômica para o país. Nesse sentido, o presente trabalho teve como objetivo verificar a liberação de voláteis de C. nucifera induzidos pela herbivoria de lagartas de Brassolis sophorae e a resposta comportamental de Winthemia analis, parasitoide de lagartas de B. sophorae, aos compostos induzidos. Adicionalmente estudou-se a biologia de W. analis. Foram coletados, por meio do processo de aeração, voláteis emitidos por C. nucifera sob os seguintes tratamentos: 1 planta sadia; 2 planta com dano mecânico e 3 planta sob herbivoria de lagartas de B. sophorae. Os voláteis coletados foram analisados quimicamente por cromatografia gasosa acoplada a espectrometria de massas (CG-EM). A resposta comportamental do parasitoide aos compostos induzidos pela herbivoria das lagartas foi testada em um olfatômetro em Y e seu ciclo de vida foi registrado a partir de 79 larvas que emergiram de 28 pupas de B. sophorae. Os compostos nonanal, decanal e duas cetonas, geranil acetona e 6-metil-5-hepten-2-ona, foram identificados nas amostras de voláteis emitidos por C. nucifera 48h após a aplicação dos três tratamentos. O homoterpeno (E)-4-8-dimetil-1,3,7-nonatrieno (DMNT) foi encontrado somente nas amostras de voláteis emitidos por C. nucifera sob herbivoria de B. sophorae e com dano mecânico. A contribuição do DMNT foi maior nas amostras de planta sob herbivoria de lagartas de B. sophorae do que nas amostras de planta com dano mecânico. Os adultos de W. analis não foram atraídos pelos extratos obtidos da aeração de plantas sob herbivoria de lagartas de B. sophorae. A taxa de emergência dos adultos de W. analis foi de aproximadamente 73%. Foi possível verificar dimorfismo sexual alar por meio de morfometria geométrica (p<0,0001). A análise morfológica dos adultos de W. analis constatou a existência de uma característica no abdômen dos machos.

Abstract:
L’ intoxication par le crabe de cocotier Birgus latro représente une entité récemment décrite en Nouvelle-Calédonie. Elle résulte de la consommation par le crustacé des fruits du faux manguier Cerbera manghas, lesquels contiennent des hétérosides cardiotoxiques tels que la nériifoline, responsable de l’intoxication. Les crustacés impliqués ont tous été capturés dans les îles Loyauté.L’intoxication est potentiellement mortelle, en raison de la toxicité cardiaque de la nériifoline. Le décès survient du fait de troubles de la conduction sévères évoluant vers l’asystolie. La constatation d’unehyperkaliémie et l’existence chez les victimes d’antécédents tels qu’un âge élevé, une insuffisance rénale, un diabète et/ou une pathologie cardio-vasculaire ont été associées aux décès. La grande similitude de l’intoxication par la nériifoline avec l’intoxication digitalique a ouvert la voie à l’utilisation thérapeutique des fractions Fab antidigitaliques, dont l’efficacité a été démontrée lors d’intoxications par le crabe de cocotier avec mise en jeu du pronostic vital.La consommation du céphalothorax du crustacé, où se situe la partie proximale du tube digestif,semble exposer aux intoxications sévères. Toutefois, des hétérosides cardiotoxiques peuvent être présents en quantité significative dans toutes les parties de l’animal. Le portage des toxines par celui-ci apparaît prolongé, ce qui rend illusoire la mise en quarantaine des birgues en préalable à leur consommation. A défaut d’une interdiction, si ce n’est de la consommation, du moins de la vente du crabe de cocotier en Nouvelle-Calédonie, la détermination de zones de capture autorisée et la mise en place d’une réglementation de sa commercialisation pourraient être de nature à limiter le risque d’intoxication potentiellement létale auquel sont exposés habitants et visiteurs des îles Loyauté
Coconut crab Birgus latro poisoning has been recently reported in New Caledonia, resulting from theconsumption of the fruits of the red-eye-sea mango tree Cerbera manghas by the crustacean. Thosefruits contain several cardenolides such as neriifolin, showing cardiac toxicity. All coconut crabsinvolved in poisoning cases have been caught in Loyalty Islands.Coconut crab poisoning had shown to be a life-threatening condition, as severe atrio-ventriculardisturbances may lead to asystolia. Hyperkaliemia, age over sixty, previous history of chronic renalfailure, diabetes mellitus and/or cardiovascular disease were noticed among patients whose poisoningswere lethal. As coconut crab poisoning mimicks digitalis poisoning, specific antidotal therapy had to beconsidered. Digoxin-specific Fab antibody fragments have been effective in the treatment of lifethreateningcoconut crab poisonings in New Caledonia.Though the cephalothorax, where upper digestive tract is located, is the most toxic part of thecrustacean, significative amounts of cardenolides have been also found in the flesh of the crustacean.As we have shown a long-term bearing of the toxins in the crustacean, attempts for its quarantine withcontrolled atoxic diet prior to its consumption would not be effective as a preventive strategy. Failingthat consumption or capture of the coconut crab would be forbidden in New Caledonia, a strictregulation limiting the caught to some low-risk sternly controlled areas should be considered
