We here review pheromone control strategies for species-specific and environmentally safe management of the tomato leafminer, Tuta absoluta (Lepidoptera: Gelechiidae). This insect pest originates from South America and is now considered to be one of the most damaging invasive pests of tomatoes in the Mediterranean Basin countries of Europe and North Africa. After presenting the general principles of sex pheromone-based control strategies, we describe strategies used to control T. absoluta including pest detection, population monitoring, mass annihilation and mating disruption techniques.

The total proteose-peptone fraction (TPP) is defined as a heat-stable soluble fraction of milk, representing about 10% of the whey protein. TPP is divided into two classes according to its origin. The first class consists of proteolysis fragments of the β-casein from the N-terminal region. These are non-hydrophobic fractions, which are the highly soluble β-CN-5P (f1-105/107); β-CN-4P (f1-28) and β-CN-1P (f29-105/107) respectively called PP5 (14.3 kDa), PP8S (9.9 kDa), and PP8F (4 kDa). The second class includes the hydrophobic fractions of glycoproteins, whose major constituents are a glycoprotein LP28, the highly hydrophobic glycoprotein LP18 and a hydrophobic peptide with apparent Mr, respectively 28 kDa, 18 kDa and 11 kDa. TPP has numerous interesting characteristics such as techno-functional properties (emulsifying and foaming actions) and biological properties (lipolysis inhibition and antimicrobial activities), making TPP usable as a potential functional ingredient for industry. In addition, these functional properties are partly governed by the major components including glycoproteins, such as LP28, due to their hydrophobic nature. [less ▲]

Body condition score (BCS) is a subjective measure of the amount of metabolizable energy stored in a live animal. Change in BCS of dairy cows is considered to be an indicator of the extent and the duration of postpartum negative energy balance. Although change in BCS over lactation is lowly heritable, heritability estimates of level of BCS range from 0.20 to 0.50. Also, BCS tends to be more heritable in mid-lactation indicating that genetic differences are more related to how well cows recover from the negative energy balance state. BCS measurements are generally highly correlated within and between lactations. Genetic correlations with BCS are unfavorable for milk, fat, and protein yield, suggesting that genetically superior producers tend to have lower BCS, especially during the lactation. Genetic correlations are generally moderate and favorable with fertility indicating that cows with higher levels of BCS would have a greater chance to conceive after insemination and fewer number of days when not pregnant. Because direct selection to improve fertility might be complicated by several factors, selection for higher levels of BCS, especially in mid-lactation, appears to be a good option to indirectly improve fertility in dairy cows.

Cassava is one of the main plants and starchy roots grown in the world. In 2008, the total yield of cassava in West Africa represented 29% of the world production. However, in many West African countries such as Senegal, cassava is not used as a staple food. In fact, the processing techniques used for cassava are poorly known. In addition, the chemical composition of local cassava varieties has not yet been determined, nor has their toxicity been assessed. In 2004, showing an aggressive agricultural policy and revived interest, the Senegalese government launched a major program for intensifying the production of cassava for food security purposes. Cassava is an important source of calories and can be an interesting option for imported rice and wheat. Although many food products made from cassava are well known in the region, their use in the Senegalese diet is rare. Nevertheless, these cassava products are found as delicacies in some restaurants, and are consumed by the Senegalese and many other Africans. The objective of the present study is to demonstrate the nutritional value and the dietary possibilities of using cassava as a staple food in Senegal. [less ▲]

During the 1990s, agricultural market reforms prevailed within the economic liberalization undertaken in many sub-Saharan countries. In these countries, government intervention in the commodity markets through marketing boards or parastatal organizations was abandoned in favor of new market reforms. Public Market Information Systems (PMIS) thus emerged as part of these reforms. Even though great positive impacts were expected from these reforms, little empirical work has been carried out to evaluate their effects. This article investigates how PMIS has affected the market performance of maize, a major staple food crop in Benin. We use a modified version of the Parity Bounds Model (PBM). This method allows the estimation of the rates of spatial market efficiency or integration, but also the estimation of the rates of market arbitrage, autarky, profitable opportunities and the violation of market arbitrage conditions. Results showed that Benin’s agricultural sector suffered from a lack of quality training in how to follow the government-supported market information system implemented in the early 1990s. Subsequently, PMIS did not significantly improve the degree of market integration, although the reforms did induce new marketing opportunities. Results also showed that the impact of PMIS is limited by other market imperfections, such as entry barriers for non-residents or for persons not in local informal trade organizations, and the non-transparent enforcement of formal regulations. This study therefore recommends the implementation of more efficiency-raising policies in order to encourage competition and to allow PMIS to fulfill the expectations of farmers and consumers. Improving food producers and traders’ access to reliable information will allow them to better exploit the market opportunities induced by the reforms. [less ▲]

This review provides a broad view of the processes and parameters involved in applying agrochemicals to the leaves of field crops. Treatment efficiency is assessed using macroscopic and microscopic approaches to investigate spray retention. With the macroscopic approach, aspects related to spray coarseness, carrier volume, leaf wettability, plant architecture, crop density and additives are addressed. Comparative studies have highlighted the wide variability in spray retention as a function of these parameters. They have failed, however, to describe the underlying physical relationships clearly enough to generalize the results. These relationships are better investigated using a microscopic approach, where drop impact behavior is established in relation to target surface and fluid properties. The wetting regime (either Wenzel or Cassie-Baxter) depends on the leaf surface microscopic roughness ratio (r) and chemical nature, fluid dynamic surface tension and drop impact energy. Adhesion, rebound and disintegration have been observed successively with increasing drop impact energy. Transitions between impact outcomes are influenced by fluid rheology and the dynamic surface tension of the fluid. The effect of surface orientation remains poorly explored, but it seems to have a limited influence on retention. Recent fundamental studies on superhydrophobicity and wetting should help practitioners in their search for an ever more rational application of agrochemicals. They could also drive the development of new systematic retention testing methods. [less ▲]

En Wallonie, les teneurs en urée du lait de tank sont déterminées dans toutes les fermes lors de chaque livraison à la laiterie par le Comité du lait. Un total de 8 295 337 données récoltées pendant l’année 2000 et la période 2002-2011 ont été analysées à l’aide d’un modèle linéaire. Les effets fixes de la région agricole ou de l’appartenance à la zone vulnérable, du mois, de l’année, des interactions entre ces paramètres ont été inclus dans le modèle. Les teneurs en matières grasse et protéique ont été utilisées comme covariables. La moyenne des teneurs en urée dans le lait a été de 255 mg.l-1. Les modèles ont permis d’expliquer 38 % et 35 % des variations des teneurs en urée pour la région agricole et pour la zone vulnérable respectivement. À l’intérieur de ces modèles, le mois, la région, l’année et l’interaction mois – année ont été les composantes les plus explicatives. Les teneurs en urée ont été plus élevées pendant la période d’avril à octobre et les plus faibles pendant la période de novembre à mars (287 vs 210 mg.l-1). Cette observation peut être expliquée par le changement de ration. Pendant la période estivale, l’herbe constitue une part variable dans la ration et peut apporter une quantité d’azote excédentaire par rapport aux besoins des animaux. Quatre pour cent des observations ont été supérieures à 350 mg.l-1 pendant la période de novembre à mars et 14 % à 400 mg.l-1 pendant la période d’avril à octobre. Dans les régions agricoles limoneuse et sablo-limoneuse, les teneurs en urée ont été plus faibles qu’en Haute Ardenne et en Ardenne (223 et 220 mg vs 278 et 284 mg.l-1 respectivement). Dans la zone vulnérable, les teneurs en urée ont été plus basses que dans la zone non vulnérable (236 vs 273 mg.l-1). Les rejets annuels azotés calculés à partir de différentes équations ont varié de 82 à 119 kg N par vache selon la région agricole. [less ▲]

The main objective of this paper is the use of milk composition data as a management tool. Milk composition, and in particular, milk fat content and fatty acid profiles may be significantly altered due to a variety of factors. These factors are reviewed in the literature; they include diet, animal (genetic) selection, management aspects and animal health. Changes in milk composition can be used as an indicator of the animal’s metabolic status or the efficiency of the feed management system. The advantages of using this kind of data as a management tool would be to allow the early detection of metabolic or management problems. The present review suggests that milk and, especially milk fat composition may be used as a sustainability management tool and as a monitoring and prevention tool for several pathologies or health disorders in dairy cattle. Further, due to the use of MIR technology, these tools may be easily implemented in practice and are relatively cheap. In the field, milk labs or milk recording agencies would be able to alert farmers whenever threshold values for disease were reached, allowing them to improve their dairy production from an economic, ecological and animal (welfare) point of view.

The main aim of this paper was to present some feeding recommendations, which, when applied on the farm, would increase nitrogen use by bovines and to give information as to how the effects of the nitrogen produced can be reduced. Ruminants have the ability to digest structural carbohydrates and to produce meat and milk proteins for human consumption. At the animal cells level, amino acids are essential for biological functions, mainly involving their maintenance and production. These amino acids are supplied by the intestinal digestion of microbial protein and feed protein that escapes microbial degradation in the rumen. Today, the efficiency of nitrogen utilization is typically low and highly variable in ruminants. Nitrogen excretion by ruminants mainly depends on the level of nitrogen intake and of the animal's productivity. Optimal N utilization may be achieved through an understanding of the key mechanisms involved in the control of N digestion and metabolism. These include the efficiency of N capture in the rumen and the protein degradation according to the type of diet and forage, the control of the rumen microorganisms involved in protein degradation and the proper formulation of the diet, avoiding feeding excess protein in relation to requirements. The dependence on energy supply in transferring feed nitrogen into milk and meat protein is strong both at the rumen and the cell levels of ruminants. The rumen metabolism is identified as the single most important factor contributing to the low level of efficient use of nitrogen in ruminants and partially depends on practical farming operations.

Recently, the European Union (EU) proposed a reform project for the Common Agricultural Policy (CAP). One of the proposed reforms consists in imposing to set aside 7% of arable land for biodiversity support purposes. About this proposal, a conference was hold in Gembloux, Belgium, on 9th November 2011. Such systems already exist in neighboring countries. French and Swiss systems were displayed in order to highlight their advantages and limits. Scientific arguments subtending such policies were presented. It was shown that creation of semi-natural elements in the agricultural matrix should be efficient to promote biodiversity. Both the quantity and the quality of these elements should be considered. Also, biodiversity is likely to provide services to agriculture, notably crop pollination and pest control. Currently, uncertainties remain on eligible areas to reach the 7% threshold. However, based on most probable scenarios, the current likely eligible areas cover only 4.3% of arable land in Wallonia. Less than 20% of Walloon farms already reach the 7% threshold proposed by the EU. If the European project is approved, it will therefore be of first importance to have a societal recognition toward farmers for their effort. To optimize positive effects of the policy on biodiversity, it is also imperative to make sure that a high biological quality is reached in the areas dedicated to biodiversity and to monitor this quality in the light of clearly defined objectives. Economical, societal and environmental issues should all be considered when applying this policy in order to improve agriculture sustainability and to stop biodiversity decline in agricultural landscapes.

Parmi les espèces invasives connaissant une expansion rapide en Europe, les plantes dites « amphibies » sont particulièrement problématiques. Elles sont capables de former des populations très denses à la surface des plans d’eau, se développant à la fois sous l’eau et hors de l’eau. La lutte contre ces espèces, en vue de l’éradication totale ou du ralentissement de l’invasion, représente un défi de taille pour les gestionnaires. Une synthèse bibliographique des méthodes de lutte existantes pour Crassula helmsii, Hydrocotyle ranunculoides, Ludwigia grandiflora, L. peploides et Myriophyllum aquaticum a été réalisée, prenant en considération leur efficacité et leur coût. Des 88 études analysées, il ressort une grande disparité d’effort de recherche (nombre d’études, échelles spatiales des études) entre méthodes de lutte et entre espèces. Néanmoins, l’efficacité des différentes méthodes de lutte est comparable pour les cinq espèces étudiées. Globalement, les cas d’éradication sont rares. Ils sont le résultat de luttes mécaniques ou chimiques, souvent couplées à des interventions complémentaires telles que la finition manuelle. Malgré une forte occurrence dans la littérature, la lutte chimique, moins fastidieuse à mettre en place et moins coûteuse que les autres méthodes, n’a montré des niveaux d’efficacité satisfaisants qu’avec certaines matières actives. De même, la lutte biologique a montré peu de résultats encourageants à ce jour. Il est à noter que certains agents de lutte biologique sont d’ores et déjà considérés comme des espèces invasives en Europe. A contrario, malgré leur faible occurrence dans la littérature, l’arrachage manuel ou mécanique suivi de finitions manuelles a donné des niveaux d’efficacité satisfaisants. Vu les difficultés de lutter contre les espèces invasives amphibies et les dommages collatéraux potentiels sur les écosystèmes, un débat impliquant scientifiques, autorités et gestionnaires de plans d’eau devra avoir lieu afin de poser les bases d’une gestion cohérente à grande échelle.

Sunflower “halva” is a popular and widely enjoyed confectionery product specific to the countries of Eastern Europe. Conventional halva has historically been produced from sesame seeds in the Middle East and Northern Africa. However, in the production of halva in Eastern Europe, sesame seeds have been largely replaced by sunflower seeds, due to the high availability of sunflower in this region and the comparable taste of the final product. Due to the importance of the cost of raw materials in the food industry, utilization of sunflower seeds in halva production may be of great interest worldwide because it offers the possibility of significantly lowering production costs. Nevertheless, oil separation and storage techniques must be perfected if sunflower halva is to fulfill its promise of becoming a cost effective alternative to sesame seed halva on a worldwide scale. The aims of this review are firstly, to describe the current state of sunflower halva technology, secondly, to isolate the main problems affecting the quality of the final product, and hirdly, to suggest areas of further research necessary to move sunflower halva production closer to reaching its full potential on the world market.

This article is written from a doctoral work on the role of scientific literature in the bioengineers' teaching at Gembloux. It is essentially a summary including recent advances in information literacy. Data analysis indicates that the bioengineers working at Gembloux publish at least as much as other scientists in Belgium, they preferentially publish articles in journals with impact factor, they read preferentially articles and they use all electronic resources available to them. Their fields of research, and reading, goes beyond the strict sense of agronomy. The courses provided at Gembloux are based on the concept of information literacy. It describes a set of skills that allow individuals to recognize an information need and enable them to locate, valuate and use needed information. The Information Literacy concept has evolved over the last two decades. Information literacy education is going well beyond the library. The skills involved are also social and cultural skills besides intellectual skills. They include media and new information technologies without being reduced to technical or technological skills. At Gembloux, the information literacy education, is registered in student's schedule, integrates production of scientific papers and is based on a methodological approach and his own didactic and specific contents.

Grassland carbon (C) sequestration can play an important role in mitigating total greenhouse gas (GHG) emissions of livestock production systems. An accurate inventory of livestock production system contribution to GHG emissions requires to think in terms of global budget, by considering both the GHG sources and the mitigation potential trough grassland soil carbon sequestration. There is a huge variability in C and GHG balances of grasslands that is mainly due to management practices and climatic conditions. The present article shows that, to reduce the uncertainties of the results, long term measurements at the field scale are necessary. Also, it shows the importance of taking the fluxes of the three main GHGs (carbon dioxide, nitrous oxide, methane) into account when calculating the GHG budget. This article also highlights the need for a better understanding of the mechanisms driving the fluxes, in relation to environmental factors and management practices, in order to propose mitigation strategies able to enhance soil carbon sequestration in soils and to reduce methane and nitrous oxide emissions.
