“…In other words, best management practices remain to be defined. For example, efficacy of biopesticides (Cordeau et al 2016), alone or in combination with chemical pesticides, possible development of resistance like that developed to chemical pesticides (Siegwart et al 2015) and effective application technologies and practices (Gan-Mor and Matthews 2003) require sound multi-disciplinary scientific research (Hynes and Boyetchko 2006;Glare et al 2012).…”

In most current farming system classifications (e.g. "conventional" versus "organic"), each type of farming system encompasses a wide variety of farming practices and performances. Classifying farming systems using concepts such as "ecological", "sustainable intensification" or "agro-ecology" is not satisfactory because the concepts "overlap in…def-initions, principles and practices, thus creating…confusion in their meanings, interpretations and implications". Existing classifications most often focus either on biotechnical functioning or on socio-economic contexts of farming systems. We reviewed the literature to develop an original analytical framework of the diversity of farming systems and agriculture models that deal with these limits. To describe this framework, we first present the main differences between three biotechnical types of farming systems differing in the role of ecosystem services and external inputs: chemical input-, biological inputand biodiversity-based farming systems. Second, we describe four key socio-economic contexts which determine development and functioning of these farming systems: globalised commodity-based food systems, circular economies, alternative food systems and integrated landscape approaches. Third, we present our original analytical framework of agriculture models, defined as biotechnical types of farming systems associated with one or a combination of socio-economic contexts differing in the role of relationships based on global market prices and "territorial embeddedness". We demonstrate the potential of this framework by describing six key agriculture models and reviewing key scientific issues in agronomy associated with each one. We then analyse the added value of our analytical framework and its generic character. Lastly, we discuss transversal research issues of the agriculture models, concerning the technologies required, their function in the bioeconomy, their multi-criteria and multilevel assessments, their co-existence and the transitions between them.

“…The growing global awareness for food quality forces countries that export agricultural products to reduce pesticide use, increasing the need for new biotechnological solutions, particularly the use natural resources (Campos et al 2005). Bioinsecticides are generally more specifi c, showing no or low toxicity to non-target animals and are environmental friends (Hynes & Boyetchko 2006). …”

Controle de Flebotomíneos (Diptera: Psychodidae) Vetores de Leishmanioses RESUMO -Os fl ebotomíneos são vetores de importância médica e veterinária, podendo transmitir leishmanioses, bartoneloses e algumas arboviroses. A adaptação de algumas espécies a locais que passaram por modifi cações humanas as aproxima dos domicílios, podendo facilitar a transmissão das doenças, e as estratégias adotadas para seu controle têm sido controvertidas. No tocante às leishmanioses, por exemplo, o que sustenta a utilização do controle vetorial e de reservatórios como estratégias de intervenção é a conjectura de que a incidência de infecção em humanos está diretamente relacionada ao número de cães infectantes e a fatores entomológicos. Dessa forma, o controle do vetor pode então oferecer solução menos onerosa e mais prática, o que conduziria a medidas preventivas efi cazes em um maior número de focos de leishmaniose. Não obstante, na complexidade dos fatores envolvidos, o controle químico continua sendo indispensável e o uso de inseticidas biológicos e plantas inseticidas, por exemplo, representam áreas de estudo a serem incentivadas e desenvolvidas, pois apresentam resultados promissores. A análise em questão representa uma oportunidade de avaliação das medidas até então adotadas, principalmente em relação aos métodos e à efi cácia dos componentes entomológicos dos programas de controle das leishmanioses. PALAVRAS-CHAVE: Antropozoonose, Lutzomyia, PhlebotomusABSTRACT -Phlebotomines are of medical and veterinary concern as they vector leishmaniasis, bartonellosis and some arboviruses. The adaptations of some species to places modifi ed by humans bring these vectors into contact with dwellings, which can facilitate disease transmission, and the vector control strategies adopted have rendered controversial results. Regarding leishmaniasis, for instance, which vector and reservoirs control can be effective, there is an assumption that the incidence of human infection is directly related to the number of infectious dogs, as well as to entomological factors. Therefore, vector control can provide a cheaper and more practical solution to prevent cases of leishmaniasis. Nevertheless, due to the complexity of the factors involved, chemical control is still essential, and biological insecticides and insecticide plants, for example, represent areas for study that should be encouraged and developed since they show promising results. This paper summarizes the control strategies adopted so far, especially the methods and effi ciency of the entomological components of leishmaniasis control programs.

“…To popularize the use of biopesticides, the components of a biopesticide formulation must: (1) ensure stability during biopesticide production, processing and storage, (2) support application, (3) protect the biopesticide from a harsh environment and (4) increase biopesticide activity at the target (Jones & Burges, 1998;Hynes & Boyetchko, 2006). Encapsulation has been recently applied in biopesticidal formulations.…”

Bacillus cereus strain C1L, screened from the rhizosphere of Lilium formosanum, prevents severe lily leaf blight. The purpose of this study was to formulate a new biopesticide by microencapsulating the C1L strain to enhance residual stability. In addition, since the viable cell number of Bacillus cereus C1L is an important factor affecting the biological effects of this fungicide, this study also used the response surface methodology and sequential quadratic programming methods to optimize the best formula for maximum viability of Bacillus cereus C1L microencapsulated by spray drying. Optimization results revealed that the strain could maintain 42% viability with 18.3% maltodextrin and 12.5% gum arabic as coating materials and spray drying at an outlet temperature of 73.5 ºC. A comparison with chemical pesticides showed that maneb was the most efficient disease inhibitor, followed by B. cereus C1L encapsulated by spray drying. The chemical pesticide probenazole and B. cereus C1L encapsulated by extrusion revealed no significant differences in disease control.
