Full textAbstract:
This paper reviews the development of all-solid-state ion-selective electrodes (ASSISEs) for agricultural crop detection. Both nutrient ions and heavy metal ions inside and outside the plant have a significant influence on crop growth. This review begins with the detection principle of ASSISEs. The second section introduces the key characteristics of ASSISE and demonstrates its feasibility in crop detection based on previous research. The third section considers the development of ASSISEs in the detection of corps internally and externally (e.g., crop nutrition, heavy metal pollution, soil salinization, N enrichment, and sensor miniaturization, etc.) and discusses the interference of the test environment. The suggestions and conclusions discussed in this paper may provide the foundation for additional research into ion detection for crops.

Spraying pesticides using row alignment in the maize seedling stage can effectively improve pesticide utilization and protect the ecological environment. Therefore, this study extracts a guidance line for maize crops using machine vision and develops an automatic row-oriented control system based on a high-clearance sprayer. First, the feature points of crop rows are extracted using a vertical projection method. Second, the candidate crop rows are obtained using a Hough transform, and two auxiliary line extraction methods for crop rows based on the slope feature outlier algorithm are proposed. Then, the guidance line of the crop rows is fitted using a tangent formula. To greatly improve the robustness of the vision algorithm, a Kalman filter is used to estimate and optimize the guidance line to obtain the guidance parameters. Finally, a visual row-oriented spraying platform based on autonomous navigation is built, and the row alignment accuracy and spraying performance are tested. The experimental results showed that, when autonomous navigation is turned on, the average algorithm time consumption of guidance line detection is 42 ms, the optimal recognition accuracy is 93.3%, the average deviation error of simulated crop rows is 3.2 cm and that of field crop rows is 4.36 cm. The test results meet the requirements of an automatic row-oriented control system, and it was found that the accuracy of row alignment decreased with increasing vehicle speed. The innovative spray performance test found that compared with the traditional spray, the inter-row pesticide savings were 20.4% and 11.4% overall, and the application performance was significantly improved.

Abstract During World War II, American agriculture grappled with labor shortages while being expected to produce more for the military and the home front. Historians have studied the use of labor sources such as migrant workers and the Women's Land Army during this time, but the Victory Farm Volunteers, a program of the federal US Crop Corps, have been largely overlooked, despite the numbers of urban youth who participated. This study examines the program as it was carried out in the states of the Great Plains, particularly its relationship to 4-H and its impact on farm production goals during the war and in the immediate postwar era.

Reducing crop cultivation is providing ecological biota for plants through Integrated Pest Management (IPM). Farmers' problems regarding pests and diseases in Banyuasin and OKU Timur, especially for food crops and horticulture farmers. The purpose of this research is to evaluate the compliance of food crops and horticulture farmers in implementing safe and environmentally friendly IPM. Study on various fields of food and horticulture farmers in Banyuasin and Ogan Komering Ulu. The research method used is purposive sampling. Observation of Plant Pests and Diseases was completed directly in the field. Then determine the disease score in each sample plant. The parameters observed in this study are the behavior of farmers towards the decision-making process of using pesticides. Pest and disease intensity, and disease attack percentage were analyzed descriptively in the form of tables and graphs, as well as correlation analysis. The highest value of diversity of pests and diseases of food and horticultural crops based on the entire area of the observed land was found in a land area of 0.25 ha, which is the area that is often found in land for crop cultivation. The average age percentage of farmers in Banyuasin and OKU East is 40 to 50 years old. The average education of farmers in Banyuasin and OKU Timur is 24 farmers. The percentage and intensity of both horticultural and food crops in Banyuasin are good because only a few farmers get a score of 2 or 1. Cultivation techniques are land preparation, land sanitation, selection of resistant varieties, spacing, irrigation, crop rotation, intercropping, mulching, natural enemies of insects, and weeding.

Full textAbstract:
AbstractSpermatogenesis in two species of free-living marine nematodes from the family Chromadoridae (Panduripharynx pacifica and Euchromadora robusta) was studied electron-microscopically. The spermatogonia of both species are undifferentiated polygonal cells with a large nucleus surrounded by a small amount of cytoplasm. In P. pacifica the cytoplasm of spermatocytes contains many Golgi bodies, cisternae of RER, ribosomes, mitochondria and dense spherical bodies. Filamentous material is accumulated in spermatids, which contain only mitochondria and a fragmented (or lobed) nucleus devoid of the nuclear envelope. The immature sperm resembles the late spermatid: its central filamentous area is surrounded by chromatine particles and occasional mitochondria. The immature sperm plasma membrane forms deep infoldings. Mature spermatozoa from the uterus consist of a small main cell body (MCB) bearing a prominent pseudopod filled with cytoskeleton filaments. The MCB contains a nucleus and mitochondria. Spermatogenesis in E. robusta (studied only in testes) resembles that described for P. pacifica, but spermatocytes of E. robusta show much lower metabolic activity and, as a result, a smaller mass of filamentous material is stored in the spermatids and immature sperm. The spermatozoa of P. pacifica and the immature sperm of E. robusta have the main ultrastructural features characteristic for nematodes (amoeboid nature, absence of axoneme, acrosome and nuclear envelope). No aberrant organelles special for many nematode sperm (membranous organelles, paracrystalline fibrous bodies and their complexes) were found during sperm development of the chromadorids studied. In this respect their spermatogenesis differs significantly from that in secernents and monhysterids.La spermatogenèse a été étudiée en microscopie électronique à transmission chez deux espèces de nématodes libres marins (Panduripharynx pacifica et Euchromadora robusta) de la famille des Chromadoridae. Les spermatogonies, chez les deux espèces, sont des cellules indifférenciées avec un grand noyau entouré d'une petite quantité de cytoplasme. Chez P. pacifica, le cytoplasme des spermatocytes contient de nombreux corps de Golgi, des cisternae du RER, des ribosomes, des mitochondries et des corps sphériques denses. Le matériel filamenteux est accumulé dans les spermatides qui contiennent seulement des mitochondries et un noyau fragmenté (ou lobé) dépourvu d'enveloppe nucléaire. Le sperme immature resemble aux dernières spermatides: son aire centrale filamenteuse est entourée par des particules de chromatine et quelques mitochondries. La membrane plasmatique du sperme immature forme des invaginations profondes. Les spermatozoïdes matures, dans l'utérus, sont constitués par un petit corps cellulaire principal (MCB) portant un pseudopode proéminent rempli de filaments de cytosquelette. Le MCB contient un noyau et des mitochondries. La spermatogenèse chez E. robusta (étudiées seulement au niveau des testicules) ressemble à celle décrite chez P. pacifica, mais les spermatocytes d' E. robusta sont le siège d'une activité métabolique plus faible et, par conséquent, une masse plus faible de matériel filamenteux est stockée dans les spermatides et dans le sperme immature. Les spermatozoïdes de P. pacifica et le sperme immature d' E. robusta ont les mêmes caractéristiques ultrastructurales pour des nématodes (nature amiboïde, absence d'axonème, d'acrosome et d'enveloppe nucléaire) mais aucune des organelles aberrantes particuliéres à de nombreux spermes de nématodes (organelles membraneuses, corps fibreux paracrystallins et leurs complexes) n'ont été identifiées pendant le développement du sperme chez les Chromadorides étudiés. Par cet aspect, leur spermatogenèse diffère significativement de celle des Secernentes et des Monhysterides.

Full textAbstract:
AbstractPostembryonic developmental stages of naturally occurring populations of Paratylenchus straeleni and P. steineri were studied. In the former species all juveniles had a well developed stylet and pharynx, while the body of the 4th stage juveniles contained numerous dark granules and this is considered the resting stage. In P. steineri the stylet and pharynx were well developed in the 2nd and 3rd stage juvenile, but the 3rd stage juvenile had numerous granules in the body suggesting it is the resting stage. Fourth stage juveniles had no stylets and the pharynx is much reduced. Because some moulting females have the stylet cone of the juveniles being shed together with the juvenile cuticle, it is concluded that the 4th stage is short-lasting. The length of the body, pharynx, tail and genital primordium as well as the index b increases in successive developmental stages. Indices a, c, c' were almost constant in all juvenile stages. The resting juvenile stage characterises species and it should be included in species descriptions for better characterisation of Paratylenchus species. Paratylenchinae: stades de developpement de Paratylenchus straeleni (De Coninck, 1931) et P. steineri Golden, 1961 (Nematoda: Tylenchulidae) - Ont ete etudies les stades de developpement post-embryonnaire de populations sauvages de Paratylenchus straeleni et de P. steineri. Chez la premiere espece tous les juveniles ont un stylet et un pharynx bien developpes alors que le corps des juveniles de 4eme stade contient de nombreux granules fonces; ce stade a donc ete considere comme le stade de quiescence. Chez P. steineri, le stylet et le pharynx sont bien developpes chez le second et troisieme stades juveniles, mais ce dernier montre de nombreux granules a l'interieur du corps, suggerant qu'il constitue le stade de quiescence. Les juveniles de 4eme stade sont depourvus de stylet et le pharynx est tres reduit. Du fait que chez les femelles en train de muer le cone du stylet des juveniles est rejete avec la cuticule des juveniles, il a ete conclu que le 4eme stade n'a qu'une courte duree de vie. Les longueurs du corps, du pharynx, de la queue et du primordium genital de meme que l'index b augmentent en passant d'un stade a l'autre. Les indices a, c et c' sont generalement constants chez tous les stades juveniles. Le stade quiescent des juveniles est caracteristique de l'espece et devrait etre inclus dans les descriptions d'especes pour une meilleure caracterisation specifique des Paratylenchus.

The new species falls into the 'group 2', based on lip patterns (Decraemer & Geraert, 1992), which contains 13 other species characterised by a cephalic region with an offset, raised, narrower oral disc, followed by broader head annuli. The main distinctive characters of the new species are: lip region truncate, very long stylet (90-100 μ m), long body 548-750 μ m, R = 127-148, conical tail, VL/VB = 1.0-1.5, spined juvenile cuticular ornamentation (multispined scales, indented at their edges) arranged in ten alternate rows, and male lateral field with four incisures. Morphometric data, illustrations and brief descriptions are presented for an Italian population of H. ortonwilliamsi Ye & Siddiqi, 1994, while, for the first time, morphometric data and illustrations are given for the male and the juvenile of H. alexis Vovlas, 1980. Hemicriconemoides macrodorus n. sp. et observations sur deux autres espèces du genre (Nematoda: Criconematidae) - Hemicriconemoides macrodorus n. sp. est décrit et figuré d'une population bisexuelle collectée dans un habitat naturel à Santa Elena, Jaén, le Sud d'Espagne. La nouvelle espèce appartient au ''groupe 2'' sur la base de la morphologie labiale (Decraemer & Geraert, 1992), groupe comptant 13 autres espèces caractérisées par une région céphalique avec un disque labial séparé du reste du corps, proéminent et rétréci, suivi des anneaux céphaliques plus larges. Les principaux caractères distinctifs de la nouvelle espèce sont: région labiale tronquée, très long stylet (90-100 μ m), corps long 548-750 μ m, R = 127-148, queue conique, VL/VB = 1.0- 1.5, ornementations cuticulaires des juvéniles avec épines (écailles avec plusieurs épines, indentées sur les côtés) arrangées en dix rangées alternées, et champ latéral du mâle comportant quatre incisures.

Rivers play an essential role to humans and ecosystems, but they also burst their banks during floods, often causing extensive damage to crop, property, and loss of lives. This paper characterizes the 2014 flood of the Indus River in Pakistan using the US Army Corps of Engineers Hydrologic Engineering Centre River Analysis System (HEC-RAS) model, integrated into a geographic information system (GIS) and satellite images from Landsat-8. The model is used to estimate the spatial extent of the flood and assess the damage that it caused by examining changes to the different land-use/land-cover (LULC) types of the river basin. Extreme flows for different return periods were estimated using a flood frequency analysis using a log-Pearson III distribution, which the Kolmogorov–Smirnov (KS) test identified as the best distribution to characterize the flow regime of the Indus River at Taunsa Barrage. The output of the flood frequency analysis was then incorporated into the HEC-RAS model to determine the spatial extent of the 2014 flood, with the accuracy of this modelling approach assessed using images from the Moderate Resolution Imaging Spectroradiometer (MODIS). The results show that a supervised classification of the Landsat images was able to identify the LULC types of the study region with a high degree of accuracy, and that the most affected LULC was crop/agricultural land, of which 50% was affected by the 2014 flood. Finally, the hydraulic simulation of extent of the 2014 flood was found to visually compare very well with the MODIS image, and the surface area of floods of different return periods was calculated. This paper provides further evidence of the benefit of using a hydrological model and satellite images for flood mapping and for flood damage assessment to inform the development of risk mitigation strategies.

Michel Eugène Chevreul entered at 17 the laboratory of Vauquelin, at the Museum. He began his investigations on animal fats in 1811. They appear as yet the most complete and the best executed experiments found in all chemistry. For the first time, he combined fractional solution, crystallization, distillation, melting point determination, and ultimate analysis. All started with the isolation of an acid and solid substance, “margaric acid”, the first of a long list of fatty acids isolated from various fats. Studying saponification, he determined that “anhydrous glycerine” was combining with water. After studying human gallstones, he discovered “cholesterine” (cholesterol). From whale spermaceti, he described “cetin” (mainly cetyl palmitate), containing no glycerol. He isolated from sheep fat a new acid he named “stearic acid”. This component was proposed in a joint patent by Chevreul and Gay-Lussac (1825) for the fabrication of very efficient candles. He discovered several volatile fatty acids in cow and goat butter (from C4 to C10). His master work (Recherches chimiques sur les corps gras d’origine animale, 1823b) contains his experimental procedures and his theoretical conclusions on the nature of fats, it may be considered as the first treatise on lipochemistry.

Full textAbstract:
Apricot fruits provide important health, economic, and nutritional benefits. Weeds damage apricot production directly and host the pests that cause damages to apricot trees. However, very few studies are available on weed control in apricot orchards. This research work was aimed at evaluating five cover crops for weed suppression in apricot orchard. The effect of living, mowed, and soil-incorporated cover corps on weeds was recorded and compared with glyphosate application and mechanical weed control. The cover crops were Vicia villosa Roth., Vicia pannonica Crantz, Triticale + V. pannonica, Phacelia tanacetifolia Benth., and Fagopyrum esculentum Moench. Five major weed species in the experimental area were Amaranthus retroflexus L., Convolvulus arvensis L., Tribulus terrestris L., Sisymbrium officinale (L.) Scop., and Sorghum halepense (L.) Per. The highest biomass production was noted for Triticale + V. pannonica in 2015 and for P. tanacetifolia in 2016. Living cover crops were effective in decreasing the weed biomass compared with the control. Both mowing and soil incorporation of cover crops were effective in decreasing weed richness and density over control. Mowed or soil-incorporated cover crops were more effective than herbicide or mechanical weed control, while F. esculentum was the least effective cover crop for suppressing weeds in apricot orchard. The results of our studies implied that cover crops could be used for weed control in apricot, and their mowing or soil incorporation could enhance their efficacy.

AbstractHydrilla is an invasive aquatic plant that has rapidly spread through many inland water bodies across the globe by outcompeting native aquatic plants. The negative impacts of hydrilla invasion have become a concern for water resource management authorities, power companies, and environmental scientists. The early detection of hydrilla infestation is very important to reduce the costs associated with control and removal efforts of this invasive species. Therefore, in this study, we aimed to develop a tool for rapid, frequent, and large-scale monitoring and predicting spatial extent of hydrilla habitat. This was achieved by integrating in situ and Landsat 8 Operational Land Imager satellite data for Lake J. Strom Thurmond, the largest US Army Corps of Engineers lake east of the Mississippi River, located on the border of Georgia and South Carolina border. The predictive model for presence of hydrilla incorporated radiometric and physical measurements, including remote-sensing reflectance, Secchi disk depth (SDD), light-attenuation coefficient (Kd), maximum depth of colonization (Zc), and percentage of light available through the water column (PLW). The model-predicted ideal habitat for hydrilla featured high SDD, Zc, and PLW values, low values of Kd. Monthly analyses based on satellite images showed that hydrilla starts growing in April, reaches peak coverage around October, begins retreating in the following months, and disappears in February. Analysis of physical and meteorological factors (i.e., water temperature, surface runoff, net inflow, precipitation) revealed that these parameters are closely associated with hydrilla extent. Management agencies can use these results not only to plan removal efforts but also to evaluate and adapt their current mitigation efforts.

The goal of the research is to create strategies for teaching students’ pragmatic competence through the use of corpora. The ability to understand and apply rules for building statements, to use statements for a variety of communicative functions in accordance with the social and cultural context of communication, is how pragmatic competence is suggested to be understood in the paper. The formation of a number of competencies within the framework of foreign language communicative competence and the process of mastering a foreign language can both be greatly enhanced by corpora, a contemporary teaching tool. The article suggests a five-stage, twelve-step algorithm for developing students' pragmatic skill using corpora.

Abstract Data comparisons were made for split or co-located samples analyzed in contract laboratories and quality assurance (QA) laboratories during environmental studies directed by the U.S. Army Corps of Engineers. Archived results were analyzed statistically as concentration ratios (contract laboratory/QA laboratory). Concentration ratios were found to be lognormally distributed, and this was the model used for comparisons. For metals in soils and volatile organic compounds (VOCs) in groundwater, 10.2% of metal ratios in soils and 5.6% of VOC ratios in groundwater exceeded limits of 0.40-2.50. Considering that both methods are multianalyte, we find that only 4.0% of the metal samples and 2.0% of the VOC samples had more than one outlier ratio per sample. More recent data produced very similar results. For VOCs, total petroleum hydrocarbons (TPHs), and explosives in soils, limits of 0.25-4.00 are suggested with the understanding that large improvements are badly needed. Even with these wide limits, approximately 42% of VOCs, 14% of TPHs, and 11% of explosives contract laboratory/QA laboratory ratios were outside these limits. Here, too, the most recent data yielded very comparable results. Sampling and preparation procedures for VOCs in soils requires immediate attention, but all methods can and should be capable of producing improved agreement between laboratories.

O objetivo deste artigo foi apresentar as dramaturgias crip como uma lógica operativa e política para criar dança. Desde os anos 1990, as principais pesquisas da área, já haviam reconhecido a importância do corpo e do movimento, para além da linguagem verbal e dos textos teatrais. Mas o que se instaura após 2000 com as teorias crip é a ênfase no fracasso, no descentramento da vida humana e na desfuncionalização do corpo-organismo como uma potência de criação aberta a outros corpos (animados e inanimados). Artistas de diversos contextos culturais têm criado suas dramaturgias da dança como dispositivos para evidenciar singularidades, incluir outras vidas e ativar estratégias de criação não antropocêntricas. Neste sentido, destacamos a pesquisa da coreana Jeong Geumhyung, da chilena Manuela Infante e do brasileiro Eduardo Fukushima.

No processo polifônico foi salientada a experiência do próprio corpo de Thi Angel, performer art, professore de História de uma escola pública periférica de Osasco-SP, que nas duas últimas décadas pesquisa sobre modificação corporal (bodymodification) e os diferentes usos do corpo. Thi Angel aponta como a trajetória de suas modificações corporais caminhava junto com o ativismo pelos direitos sexuais e reprodutivos, direitos humanos e dos animais, sua conexão com o veganismo e a arte de performar. Durante a primeira entrevista, Thi Angel narra sua estilística de existência e as escritas e marcas construídas em seu corpo por meio da arte performática, como também traz as dificuldades de baixa visão devido à doença Ceratocone, desde os 14 anos, e a emergência de transplantes em ambos os olhos. Já em 2019, o reencontro para essa escrita polifônica relembra e anuncia as ocorrências vividas após 6 anos. O posicionamento cartográfico foi o suporte e conexão com o mundo para a realização das análises dos acontecimentos e das entrevistas que foram audiogravadas e transcritas na íntegra. Para a elaboração de tais análises recorremos às epistemes teórico-metodológicas da Filosofia da Diferença, da Teoria Queer, da Teoria Crip e dos Estudos de Gênero.

AbstractIncreasing densities of Heterorhabditis megidis strain NLH-E 87.3 infective juveniles (IJ) affected invasion, reproduction, length and time to first emergence of the nematodes in larvae of the greater wax moth, Galleria mellonella. Although the number of nematodes that invaded the host increased with increasing dose, percentage of invasion declined. The number of progeny produced per host initially increased with dose. The highest production of IJ per cadaver was reached at a dose of 300 IJ per host, at that dose 62 ± 3.4 IJ were established per cadaver. Production decreased again significantly at higher densities. The smallest IJ were produced at a dose of 1000 IJ per host and the largest at a dose of 300 IJ per host. Time to first emergence of juveniles was generally shorter when the number of IJ inoculated was large (300-3000 IJ/host).Des densités croissantes de juvéniles infestants (IJ) d'Heterorhabditis megidis souche NLH-E 87.3 ont affecté la pénétration, la reproduction, la longueur du corps et la date de la première émergence des nématodes des larves de Galleria mellonella. Bien que le nombre de nématodes ayant pénétré dans l'hôte ait augmenté avec l'inoculum, le pourcentage de pénétration a décru. L'importance de la descendance produite par hôte a initialement augmenté avec l'inoculum. La production la plus forte d'IJ par cadavre a été atteinte à un taux d'inoculum de 300 IJ par hôte; à ce taux d'inoculum, 62 ± 3.4 IJ par cadavre avaient pénétré. La production d'IJ a de nouveau diminué significativement aux taux d'inoculum plus élevés. Les IJ les plus petits ont été obtenus au taux d'inoculum de 1000 IJ par hôte. Le temps écoulé jusqu'à la première sortie des juvéniles hors de l'insecte a été généralement plus court lorsque le taux d'inoculum était élevé (300-3000 IJ/hôte).

The experiment was conducted to assess the effects of different inclusion levels of cooked kidney bean meal as non - conventional feedstuff on the growth performance of broilers chicks. The test diets were formulated such that, diet T1 (control diet) contained no kidney bean meal, diet T2 contained 20% cooked kidney bean meal, diet T3 contained 40%cooked kidney bean meal and diet T4 contained 60%cooked kidney bean meal. The trial lasted for eight weeks and the following parameters were measured weekly during the course of the experiment. Feed intake, body weight, weight gain, feed conversion ratio, nutrient digestibility, length of body parts and carcass proportion. The result showed that there were significant differences (p<0.05) in the Final body weights and average mean body weights. The birds fed 20% cooked kidney bean meal diets had the highest mean body weight (1220g) while birds fed 60% cooked kidney bean meal had the lowest mean body weight (941.20g). There was no significant difference (p>0.05) in the feed intake of birds fed cooked kidney bean meal diets. There were no significant difference (p>0.05) in the length of body parts and carcass proportion except thigh and wing, crop of birds fed cooked kidney bean meal diets respectively. Significant difference (P>0.05) were not observed in the dry matter, ether extract, crude fibre and ash digestibility except in crude protein and NFE (Nitrogen Free Extract). There were no significant differences (P>0.05) among birds fed the four experimental diets in parameters considered in the carcass proportion except the wing and the crop. It was however concluded that the addition of cooked kidney bean meal had a positive effect on the performance as well as CPdigestibility of the birds when their inclusion in the diet is within the range of 20-40% replacement of conventional plant protein sources.
L'expérience a été menée pour évaluer les effets de différents niveaux d'inclusion de tourteau de haricots rouges cuits comme aliment non conventionnel sur les performances de croissance des poussins de chair. Les régimes testés ont été formulés de telle sorte que le régime T1 (régime témoin) ne contenait pas de farine de haricots rouges, le régime T2 contenait 20 % de farine de haricots rouges cuits, le régime T3 contenait 40 % de farine de haricots rouges cuits et le régime T4 contenait 60 % de farine de haricots rouges cuits. L'essai a duré huit semaines et les paramètres suivants ont été mesurés chaque semaine au cours de l'expérience. Consommation alimentaire, poids corporel, gain de poids, taux de conversion alimentaire, digestibilité des nutriments, longueur des parties du corps et proportion de la carcasse. Le résultat a montré qu'il y avait des différences significatives (p<0,05) entre les poids corporels finaux et les poids corporels moyens moyens. Les oiseaux nourris avec 20 % de farine de haricots rouges cuits avaient le poids corporel moyen le plus élevé (1220 g), tandis que les oiseaux nourris avec 60 % de farine de haricots rouges cuits avaient le poids corporel moyen le plus bas (941,20 g). Il n'y avait pas de différence significative (p>0,05) dans la consommation alimentaire des oiseaux nourris avec des régimes à base de farine de haricots rouges cuits. Il n'y avait pas de différence significative (p>0,05) dans la longueur des parties du corps et la proportion de carcasses, à l'exception de la cuisse et de l'aile, culture d'oiseaux nourris respectivement avec des régimes à base de farine de haricots rouges cuits. Aucune différence significative (P>0,05) n'a été observée dans la matière sèche, l'extrait d'éther, la fibre brute et la digestibilité des cendres, sauf dans la protéine brute et le NFE (Nitrogen Free Extract). Il n'y avait pas de différences significatives (P>0,05) entre les oiseaux nourris avec les quatre régimes expérimentaux dans les paramètres pris en compte dans la proportion de carcasse, à l'exception de l'aile et du jabot. Il a cependant été conclu que l'ajout de farine de haricots rouges cuits avait un effet positif sur les performances ainsi que sur la digestibilité des CP des oiseaux lorsque leur inclusion dans l'alimentation se situe dans la fourchette de remplacement de 20 à 40 % des sources de protéines végétales conventionnelles.

Abstract Detailed descriptions are given of the amphimictic nematode strains PS1158, PS2052 and PS2160, which are unusual in that they only differ in predominant body handedness. Although these strains are morphologically identical in all other respects, published reproductive data and new DNA sequence data of the D2/D3 region of the large subunit rRNA gene show that they do represent two separate species. On the basis of comparison with type material, the left-handed strains PS1158 and PS2160 are identified as Acrobeloides bodenheimeri, and the right-handed strain PS2052 as A. camberenensis, which is re-instated as a valid species. A. bodenheimeri and its relatives exhibit various types of diagnostic and taxonomic problems at species level, and it is shown that D2/D3 sequence data provide an important new diagnostic tool for addressing these problems. Phylogenetic analysis shows that two right-handed parthenogenetic strains identified as A. maximus represent a third species which is more closely related to A. camberenensis than to A. bodenheimeri. Caracterisation morphologique et moleculaire de deux especes intersteriles de chiralite contraire (Nematoda: Cephalobidae) - Une description detaillee est donnee des souches amphimictiques de nematodes PS1158, PS2052 et PS2160, souches inhabituelles car differant par la chiralite du corps. Bien que ces souches soient morphologiquement identiques sous tout autre rapport, les resultats publies de tests de croisement et de nouvelles donnees concernant la sequence d'ADN de la region D2/D3 du gene de la grosse sous-unite d'ARN ribosomal montrent qu'elles representent en fait deux especes distinctes. Se fondant sur une comparaison avec le materiel type, les souches sinistres PS1158 et PS2160 sont identifiees comme Acrobeloides bodenheimeri et la souche dextre PS2052 comme A. camberenensis, ainsi retabli comme espece valide. A. bodenheimeri et les especes proches posent differents problemes diagnostiques et taxinomiques au niveau specifique, et nous montrons que les donnees de sequence D2/D3 fournissent un nouvel outil diagnostique important pour aborder ces problemes.

To address the current difficult problem of scientifically assessing the health status of date palm trees due to a single parameter for date palm health assessment, an imperfect index system, and low precision. In this paper, using jujube trees in 224 regiment of the 14th division of Xinjiang Production and Construction Corps “Kunyu city” as the research object, we carried out the inversion study of various physicochemical parameters of jujube trees (canopy chlorophyll content, leaf area index (LAI), tree height, canopy area) using the unmanned aerial vehicle (UAV) hyperspectral imagery of jujube trees during the period of fruit expansion, and put forward a model for assessing the health of jujube trees based on multiple physicochemical parameters. First, we calculated six spectral indices for inversion of chlorophyll content and four spectral index for inversion of LAI, analyzed the spectral index with high correlation with chlorophyll content and LAI of jujube trees canopy, and constructed the inversion models of chlorophyll content and LAI. Second, the Mask R-CNN model was used to achieve jujube trees’ canopy segmentation and area extraction, and the segmented canopy was matched with the Canopy Height Model (CHM) for jujube trees’ height extraction. Finally, based on the four physicochemical parameters of inversion, we construct four jujube trees’ health assessment models, namely, Partial Least Squares Regression Analysis (PLSR), Random Forest (RF), Support Vector Machines (SVM), and Decision Tree (DT). The results showed that the R2 of the PLSR tree health assessment model constructed based on the multi-physical and chemical parameters of chlorophyll content, LAI, tree height, and canopy area was 0.853, and the RMSE was 0.3. Compared with the jujube trees’ health assessment models constructed by RF, SVM, and DT, the R2 increased by 0.127, 0.386, and 0.165, and the RMSE decreased by 0.04, 0.175, and 0.063, respectively. This paper can achieve rapid and accurate inversion of multi-physical and chemical parameters of jujube trees with the help of UAV hyperspectral images, and the PLSR model constructed based on multi-physical and chemical parameters can accurately assess the health status of jujube trees and provide a reference for a scientific and reasonable assessment of jujube trees’ health.

Abstract This paper introduces the open-source English Language Learning Insight, Proficiency and Skills Evaluation (ELLIPSE) corpus. The corpus comprises ~6,500 essays written by English language learners (ELLs). All essays were written during state-wide standardized annual testing in the United States. The essays were written on 29 different independent prompts that required no background knowledge on the part of the writer. Individual difference information is made available for each essay including economic status, gender, grade level (8–12), and race/ethnicity. Each essay was scored by two trained human raters for English language proficiency including an overall score of English proficiency and analytic scores for cohesion, syntax, vocabulary, phraseology, grammar, and conventions. The paper provides reliability on the human judgments of proficiency reported for the corpus. The ELLIPSE corpus addresses many of the concerns found in existing learner corpora including unique holistic and analytic scores for each ELL essay. The corpus also includes limited demographic and individual difference data for each ELL.

AbstractInnovative sources of soil fertility are of utmost importance to growers in light of rising fertilizer costs and environmental concerns. Integrating livestock and crop production is one channel by which agricultural practitioners can enhance soil fertility. For this research, soil fertility was analyzed in pastured poultry/crop agroecosystems to determine whether free-ranging birds and pasture could be used to replace or supplement non-manure-based fertilizers. Soils from adjacent cropped areas were compared to plots with a recent history of pastured poultry use on two farms, and crop plants were grown in each type of soil in a replicated greenhouse experiment. Spatial variation in soil fertility was also assessed relative to location of poultry coops. Pastured poultry plots had elevated soil total C, total N, NH4+–N, NO3−–N, Olsen P, exchangeable K, organic matter, cation exchange capacity and electrical conductivity relative to the control of typically managed organic farm soils without pastured animal inputs. These soil fertility changes conferred greater biomass and height to sunflowers and beans grown in these soils relative to control soils for most treatments. Results suggest that pastured poultry can effectively fertilize soil for certain crops but that a need exists for more research into (1) phosphorus management and (2) ensuring a spatially uniform distribution of manure.

Abstract Post-fixation with osmium tetroxide (OsO4), prior to examination by electron microscopy, enables nematodes to be located in epoxy-resin blocks, and improves contrast of ultrastructural features. For specimen visibility, alternatives to OsO4 were examined as it can inhibit antigenicity, thus preventing application of serological techniques. Basic fuchsin stain does not affect antigenicity and when applied to trichodorids enabled specimens to be readily located in the block, but had several disadvantages such as causing substantial alteration of the nematode structure. Safranin-O stain enabled Paratrichodorus anemones and P. pachydermus specimens to be located in resin blocks, different parts of the nematode body to be distinguished, and did not affect specimen ultrastructure. Also, with viruliferous specimens it allowed immunogold labelling techniques to be applied for identifying tobacco rattle virus particles at the site of retention in the nematodes. Safranin-O is fluorescent and this feature was used to examine sections from the spicula region of a male P. pachydermus specimen under a confocal laser scanning microscope. La post-fixation au tétroxyde d’osmium (OsO4) avant l’observation en microscopie électronique empêche la localisation des nématodes dans les blocs de résine epoxy et augmente le contraste des caractéristiques ultrastructurales. Pour la localisation des spécimens, des solutions alternatives au OsO4, qui peut inhiber l’antigénicité et donc empêcher l’application de techniques sérologiques, ont été examinées. Le coloration à la fuschine basique n’affecte pas l’antigénicité et permet de situer les spécimens dans les blocs, mais elle présente de nombreux désavantages telle l’altération substantielle des structures du nématode. La safranine-O permet la localisation de Paratrichodorus anemones et de P. pachydermus, les différentes parties du corps du nématode étant alors identifiables, et n’affecte en rien l’ultrastructure du nématode. Chez les spécimens portant des virus, elle permet également l’utilisation de techniques de marquage immunologique à l’or pour identifier les particules du virus du tobacco rattle dans les sites de rétention chez le nématode. La safranine-O est fluorescente et cette particularité a été utilisée pour observer des sections de la région des spicules chez un mâle de P. pachydermus en microscopie confocale à balayage.

AbstractThe effect of temperature, dose and storage period on the infectivity and development of Heterorhabditis megidis (strain NLH-E 87.3) infective juveniles (IJ) was studied in the laboratory. IJ were stored at 5, 10, 15 and 20°C for a period of up to 70 days (10 weeks). Every second week, mortality, infectivity, reproductive capacity, time to emergence and length of IJ were examined. Galleria mellonella larvae were infested with doses of one and 30 IJ. As the period of storage increased, the number of active nematodes, the infectivity and the reproduction of IJ decreased both at low and high temperatures. Time to first emergence and body length of IJ were significantly affected by time, storage temperature and inoculum level. Independent of the dose and storage periods, highest infectivity and optimal development were observed when IJ were stored at 10 and 15°C. Effets de la durée du stockage et de la température sur le pouvoir infestant, la reproduction et le développement d'Heterorhabditis megidis parasitant Galleria mellonella - Les effets de la température, de la dose d'inoculum et de la durée du stockage sur le pouvoir infestant et le développement des juvéniles infestants (JI) d'Heterorhabditis megidis ont été étudiés au laboratoire. Les JI ont été stockés à 5, 7, 10, 15 et 20°C pendant une période allant jusqu'à 70 jours (10 semaines). Toutes les 2 semaines ont été examinées: la mortalité, le pouvoir infestant, la capacité de reproduction, la durée de l'émergence et la longueur de ces JI. Les larves de Galleria mellonella ont été infestées à deux doses: un et 30 JI. Lorsque la durée du stockage augmente, le nombre de nématodes actifs, le pouvoir infestant et la reproduction des JI diminuent, aussi bien à basse qu'à haute température. La durée de la première émergence et la longueur du corps des JI ont été significativement affectées par la durée et la température du stockage, ainsi que par la valeur de l'inoculum. De façon indépendante de cette dernière valeur et de la durée de stockage, le pouvoir infestant la plus élevée et le développement optimal ont été observés lorsque les JI sont stockés à 10 et 15°C.

AbstractHeterorhabditis bacteriophora and H. indica were cultured in vitro in monoxenic liquid cultures. Nematodes were examined for morphological characters which can be used to determine the sexes in all juvenile stages. When hatching from the egg no sex-specific characters could be distinguished. Twelve hours later sex determination resulted in male phenotypes which were identified by the asymmetric shape of the primordial testis. Female phenotypes, with symmetrical primordial gonads, were observed 12 h later. Of the eggs laid by the parental hermaphrodite 57% developed to amphimictic adults. The other individuals were determined to become automictic dauer juveniles which further develop to hermaphrodites. The pre-dauer J1 was the last of the first juvenile stages to be determined. They moult to the pre-dauer second stage juvenile (J2D) which is distinguished from the other J2 stages by a thin and spindle-like shape, elongated pharynx and needle-like tip of the tail. The late JD2 stage is immobile, pharyngeal pumping ceases and intercalated fat reserves make it appear darker then the amphimictic J2. The further development to adults is described and the occurrence of the different stages in liquid culture documented.

Ils ont mue en stade pre-dauer J2 qui peut etre differencie des autres stades J2 par le corps mince et fusiforme, un pharynx allonge et l'extemite de la queue tres effilee. Le dernier stade DJ2 est immobile, le pompage pharyngien cesse et des reserves lipidiques interstitielles le rendent plus sombre que chez le stade amphimictique J2. Le developpement jusqu'a l'adulte est decrit et l'apparition de differents stades en milieu de culture liquide est detaillee.

Earlier work showed that the number of eggs produced by a virgin female is smaller than that produced by a mated female. The current paper shows that this results not from a difference in rates of egg production, but from the operation of the same linear rate for different times. Denervating the corpus allatum in virgin females extends the time over which the same rate of egg production operates, thus indicating that the inhibition of egg production in virgin females results from a nervous inhibition of the corpus allatum. The initial rate of emptying of the crop is also approximately linear in both virgin and mated females. Later, crop emptying slows in virgins and remains linear in mated females. When these relationships are disturbed by plugging the anus of females before feeding, the rate of crop emptying in virgins more closely resembles that in mated females, and the difference in egg production between mated and virgin females disappears. These results are put into the context of a hypothesis which predicts that the degree of distension of the crop is an important determinant of the length of time that the corpus allatum remains active.

Cependant, les changements dans la consommation alimentaire des ménages urbains camerounais nous ont amenés à nous interroger sur le rôle et la part de l’huile rouge dans la consommation actuelle en corps gras des ménages au Cameroun, et plus particulièrement à Yaoundé, capitale multiculturelle du fait de la diversité d’origine ethnique de sa population. Les présentes données rassemblent, sous forme de deux tableaux Excel stockés sur le Dataverse de l’UMR System au CIRAD, les résultats de deux enquêtes effectuées au premier semestre 2016 dans les différents quartiers de Yaoundé, sur la base d’un échantillonnage raisonné de 124 ménagères et de 29 restauratrices de Yaoundé. Ces enquêtes portent sur la consommation d’huiles alimentaires (types d’huile et quantités) et, concernant l’huile rouge, sur les pratiques d’approvisionnement (fournisseur, fréquence, prix et volume), la perception de la qualité, les dénominations, les utilisations et les propriétés culinaires recherchées afin de préparer les plats traditionnels camerounais.

AbstractSoil core samples were taken from a commercial potato field before emergence of the potato crop, during crop development and after harvesting. Leachates from the cores were analysed in an in vitro hatching assay in the laboratory for activity towards the potato cyst nematodes (PCN), Globodera rostochiensis and G. pallida. Hatching activity in the soil increased rapidly after plant emergence and peaked between 2 and 5 weeks after emergence; thereafter, at about the onset of flowering, hatching factor activity decreased markedly. The soil cores collected in the first 2 weeks after plant emergence contained significantly greater hatching activity towards G. pallida than G. rostochiensis, indicating that G. pallida-selective hatching factors were produced by the host crop earlier than G. rostochiensis-selective hatching factors. Soil cores collected from the potato ridge and the furrows at various depths and distances from the host plants differed in the distribution of G. pallida-selective and G. rostochiensis-selective hatching activity within the soil profile. Globodera pallida-selective hatching activity had greater vertical and horizontal mobility in the soil profile and elicited significantly greater hatching responses than G. rostochiensis beyond the region of the rhizosphere. Significant levels of hatching factor activity could be detected in the field 90 days after harvesting of the potato crop.

AbstractSteinernema arenarium (Nematoda: Steinernematidae) completed a single generation in larvae of Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae), at 23 degrees C. From the time of initial exposure of the insects to the nematodes, infection, formation of adults, and appearance of infective juveniles (IJ) occurred at 18, 48, and 120 h, respectively. In second instar (L2) O. sulcatus, small stunted females developed, but in late instar larvae (L6), stunted females co-existed with normal sized females. The stunted female nematodes developing in L6 O. sulcatus produced stunted progeny and the giant females normal sized IJ. The total body length and greatest body diameter of the larger IJ from O. sulcatus were similar to those recorded for normal sized IJ exiting Galleria mellonella (Lepidoptera: Pyralidae). The length of the small IJ was just over half the length of the large IJ produced in O. sulcatus and G. mellonella. IJ of both size groups were pathogenic to G. mellonella, and the small IJ matured into normal giant females within larger hosts. Small IJ of S. arenarium were able to infect L2 O. sulcatus in significantly higher numbers than normal sized IJ. The reasons for the single generation and production of stunted females and IJ are addressed. Infestation, developpement et reproduction du nematode entomopathogene Steinernema arenarium (Nematoda: Steinernematidae) sur Otiorhynchus sulcatus (Coleoptera: Curculionidae)- Steinernema arenarium (Nematoda: Steinernematidae) n'accomplit, a 23 degrees C, qu'une seule generation dans les larves d'Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae). A partir de la mise en presence de l'insecte et des nematodes, l'infestation, la formation des adultes et l'apparition des juveniles infestants (IJ) se produisent en, respectivement, 18, 48 et 120 heures. Dans les larves de deuxieme stade (L2) d'O. sulcatus il se developpe des femelles petites et rabougries tandis que dans les larves de dernier stade (L6) de petites femelles coexistent avec des femelles de taille normale. Les petites femelles du nematode qui se sont developpees dans les L6 d'O. sulcatus ont une descendance rabougrie tandis que les femelles geantes produisent des IJ de taille normale. La longueur du corps et le diametre maximal des plus grandes IJ provenant d'O. sulcatus sont equivalents a ceux des IJ de taille normale provenant de Galleria mellonella (Lepidoptera: Pyralidae). La longueur des petites IJ depasse de peu la moitie de celle des grandes IJ produites chez O. sulcatus et G. mellonella. Les IJ des deux groupes de taille sont pathogenes envers G. mellonella, et les petites IJ se developpent en femelles geantes, normales, dans des hotes de plus grande taille. Les petites IJ de S. arenarium peuvent infester O. sulcatus en nombre significativement plus eleve que les IJ de taille normale. Les causes de la generation unique et de la production de femelles et IJ rabougris sont discutees.

Background and aim: Soil structure is an important indicator of the quality of soil, but detecting the early signs of soil degradation from soil structure is difficult. Developing precise instruments able to diagnose soil structure quickly is therefore critical to improve management practices. Here, the objective is to develop an instrument analysing the roughness of surfaces resulting from the fracture of soil cores, and to test the instrument’s ability to detect changes in soil structure cause by crop type and tillage. We have designed and constructed a 3D laser profilometer suitable for analysing standard soil cores. The 3D soil profiles were first assembled into a 3D surface using image analysis before roughness indicators could be computed. The method was tested by analysing how soil surface roughness was affected by crop varieties (barley and bean) and tillage (conventional tillage and no tillage). Results showed the method is precise and could reliably detect an influence of crop type and tillage on the roughness indicator. It was also observed that tillage reduced the difference in soil structure between the different cultures. Also, the soil in which barley grew had significantly lower roughness, irrespective of the tillage method. This could indicate that the roughness indicator is affected by biopores created by the root system. In conclusion, roughness indicators obtained from the fracture of soil cores can be easily obtained by laser profilometry and could offer a reliable method for assessing the effect of crop types and soil management on soil quality.
