Aedes albopictus is a major vector of arboviruses. Better understanding of its sex determination is crucial for developing mosquito control tools, especially genetic sexing strains. In Aedes aegypti, Nix is the primary gene responsible for masculinization and Nix-expressing genetic females develop into fertile, albeit flightless, males. In Ae. albo...
Drought is one of the most destructive environmental challenges for agriculture, and citrus trees are cultivated in semiarid areas. The current study used physiological and untarget mass spectrometry analysis to assess the differential response to drought and rehydration in leaves and roots of three scion/rootstock combinations in which the same sc...
Fruit quality traits are directly linked to consumer acceptability, and thus key targets for banana breeding programs. We explored the genetic control of three major organoleptic and ripening-related traits, namely pulp acidity (pH), firmness (PF) and dry matter content (DMC), over a 7-day ripening period and three production cycles in a banana seg...
Coffee berry borer (CBB) (Hypothenemus hampei; Coleoptera: Curculionidae: Scolytinae) is a major insect pest affecting coffee cultivation that causes large economic losses worldwide. Characteristics related to its life cycle makes it very difficult to control. Usually, CBB control measures are carried out at plot scale, with almost no actions taken...
La bioéconomie questionne le renouvellement des méthodes d'évaluation des performances des filières. Les méthodes traditionnelles très liées à l'économe industrielle restent polarisées par des indicateurs macro-économiques ou d'intégration intersectorielle. Elles rendent peu compte des coûts cachés ou externalités sociales et environnementales. Dan...
This chapter focuses on the role of surveillance in the policy process. It promotes a general framework to assess the effectiveness of health surveillance systems from a social science perspective, based on the concept of real governance. Effectiveness of animal health surveillance systems is addressed through the analysis of the gaps between, on t...
Severe Acute Malnutrition (SAM) is still a public health issue in many low-income and middle-income countries. Its management has changed with the development of Ready-to-Use Therapeutic Foods (RUTF) that are energy-dense, lipid-based, micronutrient-enriched foods. The purpose of the present study was to define some aspects of the nutritional profi...
Trophic dynamics of integrated rice and fish farming (IRF) systems were studied in irrigated rice plots stocked with common carp in Madagascar. Fish feeding behavior was assessed by analyzing stable carbon and nitrogen isotopes of fish and natural feed sources. Stable isotope signatures of 45-day-old carp fry introduced into rice plots (δ13C = −18....
Coastal agricultural systems in Southeast Asia are vulnerable to climate change. The combination of rising sea levels and extreme rainfall events is eroding fragile coastlines that protect emblematic “rice bowls” across the region. A series of recent damaging floods in Southeastern Thailand has raised concerns about their increased frequency. Local...
