Cette révision de la faune syrphidologique du canton de Genève apporte 15 additions à la liste cantonale, cinq d’entre elles sont également nouvelles pour la faune suisse [Mallota fuciformis (Fabricius, 1794), Melangyna quadrimaculata (Verrall, 1873), Merodon moenium (Wiedemann, 1822), Microdon mutabilis (L., 1758), Pocota personata (Harris, 1780)]...
In the context of biodiversity maintenance in agricultural environments and of risk reduction related to the use of phytosanitary products, it seems essential to improve our knowledge of the beneficial insects that develop in these ecosystems.
This article reviews the state of knowledge regarding insect auxiliaries and highlights the main faunal, e...
Description of the subject: This study focuses on the vegetation and Diptera Syrphidae found in biodiversity promotion surfaces (BPSs) of the “extensive meadows” type, within an agricultural context.
Objectives: The objective was to test the influence of the “size” and “botanical quality” factors of BPSs on the syrphifauna that develops there. It a...
The leafhopper Scaphoideus titanus is the vector of Flavescence dorée of grapevine, a serious phytoplasma disease. The potential distribution of S. titanus, its life cycle and the possibility of a second generation have been estimated by 2050 and 2070. Two warming scenarios were chosen, namely an optimistic (RCP2,6) and a pessimistic (RCP8,5) green...
Description du sujet. Cette étude traite de la végétation et des Diptères Syrphidae au sein de Surfaces de Promotion de la Biodiversité (SPB) de type « prairies extensives » en contexte agricole. Objectifs. L’objectif consiste à tester l’influence des facteurs « taille » et « qualité botanique » des SPB sur la syrphifaune qui s’y développe. Il s’ag...
In 2017, the populations of typhlodromes were evaluated in 12 vineyard parcels in the canton of Geneva (Switzerland) with two quantitative samplings carried out in June and August. Typhlodromes were present in each of the studied parcels and were neither influenced by the size and botanical quality of adjacent Biodiversity Promotion Areas (BBAs), n...
The emergence of Drosophila suzukii and its associated negative effects on certain grape varieties, requires wine producers to act in order to protect their crops from infestation. While most defensive measures can be considered prophylactic, the use of insecticides is also sometimes necessary. Spinosad is one such example of a recommended insectic...
Precision fruticulture addresses site or tree-adapted crop management. In the present study, soil and tree status, as well as fruit quality at harvest were analysed in a commercial apple (Malus × domestica ‘Gala Brookfield’/Pajam1) orchard in a temperate climate. Trees were irrigated in addition to precipitation. Three irrigation levels (0, 50 and...
Plants and insects depend on climatic factors (temperature, solar radiation, precipitations, relative humidity and CO2) for their development. Current knowledge suggests that climate change can alter plants and insects devel- opment and affect their interactions. Shifts in tritrophic relations are of particular concern for Integrated Pest Managemen...
Under the current climate scenarios for Switzerland, the climate continue to warm over the coming decades. This will probably modify the complex of pest species found in crops as well as their phenology. A network of plots was set up in the Geneva Canton between2014 and 2016 in order to monitor nine emerging pest insects: Halyomorpha halys, Nezara...
Selon les derniers scénarios climatiques établis pour la Suisse, le climat continuera de se réchauffer de manière significative durant les décennies à venir. Un changement à ce niveau risque de modifier le cortège et la phénologie des ravageurs retrouvés dans les cultures. Un réseau de parcelles de surveillance de neufs insectes ravageurs émergents...
The stinkbugs Halyomorpha halys and Nezara viridula are two Pentatomidae that appeared recently in Switzerland and that become more and more problematic for fruit and vegetable production. In laboratory bioassays conducted at Agroscope Changins, residual effects of spinosad, chlorpyrifos, thiacloprid and azadirachtin A were tested on adults of the...
The association of hoverflies with vineyards and the response of the species to different types of ground cover management were investigated in two Swiss vineyards sampled using Malaise and emergence traps from March to July 2014. Eight of the 21 species collected in emergence traps, some of them with conservation interest, were identified as havin...

Les produits phytosanitaires (biologique ou synthétique) sont des substances utilisées pour gérer les populations d'ennemis des cultures: insectes, mauvaises herbes ou champignons. La majorité de ces produits sont appliquée en agriculture (fruits, légumes et céréales).
Ce projet a permis d’identifier les principaux organismes émergents ennemis des cultures (insectes, adventices, microorganismes) ainsi que de tester et mettre en place des méthodes de détection adéquates. Un suivi annuel de la majeure partie de ces organismes a pu être entrepris et a conduit à des résultats très informatifs au sujet de leur présenc...
The interest of a ground cover between rows of vineyards is now well known and so are its failings: competition,
management and risks of frost. Selecting plant species for ground covers could mitigate the negative impacts while keeping their advantages. The main goal is to obtain a mix of species which, on the long term and with minimal management,...
Pests are becoming increasingly resistant to the active ingredients of insecticides applied. The exclusion nets are an alternative mean to struggle against pests. Two systems of exclusion nets against pests in apple production were assessed in Victoriaville (Quebec, Canada). Other parameters such as climate and the incidence of scab (Venturia inaeq...
Ground cover influence on Carabidae (Coleoptera) populations and potential interest for bio-control of some vineyards pests. Description of the subject. This paper deals with carabid populations within vineyards. Objectives. The objectives were to evaluate the effects of ground cover management on carabid populations and to understand the potential...
The entomological abundance, diversity and richness of three methods of tree line management were compared in an orchard under organic husbandry in Victoriaville (QC, Canada). The tested treatments were the “Sandwich” system with Trifolium repens, Lotus corniculatus and Festuca ovina (TLF), the “Sandwich” system with Pilosella officinarum (EP) and...
Description of the subject. This paper deals with carabid populations within vineyards.
Objectives. The objectives were to evaluate the effects of ground cover management on carabid populations and to understand the potential of these beetles as predators of some grapevine pests.
Method. Two vineyards, located in Geneva (Switzerland), were sampled...
Invasive multicoloured Asian lady beetle (Harmonia axyridis) causes two major problems: the competition against indigenous ladybirds taking their ecological niche and the bad taint given to the grape berries at harvesting time when their number is too high. In United States of America, at the end of the growing
season, H. axyridis move massively in...
L’intérêt, agronomique et environnemental, de l’installation de couvertures végétales dans les vignes et les vergers est aujourd’hui largement reconnu. Un tel enherbement des cultures pérennes n’est cependant pas exempt de défauts: concurrence vis-à-vis de la culture, entretien et risques de gel, notamment. Un choix raisonné des espèces utilisées p...
Ground beetles (Coleoptera: Carabidae) are important beneficials in apple orchards. In 2014, the influence
of production systems was studied on the diversity and abundance of ground beetles species in two apple orchards (cultivated under the directive of integrated or organic production). The IP-orchard showed a greater number of regular species th...
Le calcium est une élément essentiel pour le pommier car il contribue à la fermeté tout en réduisant les apparitions de Bitter pit. L'absoption de l'élément par les racines n'étant pas suffisante, seules des pulvérisatios répétées d'engrais foliaires calciques se sont révélées réellement efficaces pour augmenter la teneur en calcium des fruits. Cet...
In this work we present Shifted Excitation Raman Difference Spectroscopy (SERDS) as a potential spectroscopic tool for outdoor measurements in precision agriculture. A dual-wavelength diode laser at 785 nm is used as an excitation light source which provides an optical power up to 100 mW in cw-operation. Both emission lines for SERDS show single mo...
We report on the first application of time-resolved reflectance spectroscopy in the orchards for the nondestructive assessment of apple optical properties during growth. A portable dual-wavelength (650 nm, 780 nm) system was developed and used to assess the absorption coefficient and the reduced scattering coefficient of apples during growth.
Dans les années 1980, plusieurs insectes pommicoles commençaient à développer des résistances à
diverses matières actives biologiques et de synthèse. La recherche agronomique et les arboriculteurs
helvétiques ont cherché des solutions pour freiner ce problème important. Au début des années 1990, une
solution environnementale et économiquement appli...
To reduce economic losses, producers have no choice than controlling pests with chemical insecticides with a negative impact on the environment as well as on beneficial organisms. In this context, efficient and selective Biological Control Agents such as entomopathogenic fungi, should be identified for their integration in pest management strategie...
Une des contraintes majeures pour les viticulteurs et les arboriculteurs sera de faire face aux ennemis des
cultures émergents (par exemple Drosophila suzukii, Halyomorpha halys, Cyperus esculentus, etc.), liés aux
changements climatiques (CC). Avec le réchauffement climatique, plusieurs espèces non répertoriées en
Suisse sont susceptibles de s’int...
Floral strips help preservation of biodiversity which may be useful to reduce the threat of pest insects with beneficials. Two blends of flowering plants were tested: “wild” and “cultivated”. Every week (June to September 2013), the flowering degree of each species has been noted. Twice a week (in July and August), captures were realised with a swe...
The multicolored Asian lady beetle (Harmonia axyridis) is very efficient against aphids and easy to
rear in the laboratory. So, H. axyridis were used and released to control aphid damages on several
crops in organic farming. In Europe, a few years after these releases, several studies showed that H.
axyridis is the species most represented in agric...
Aphids (M. persicae) and true bugs (L. rugulipennis) are some of the most important pest insects of
several crops. They can decrease growth and reduce yield as well as transmit plant viruses. In order
to reduce economic losses, producers must control those pests with pesticides application to decrease
the damages. The use of insecticides unfortunat...
The virulence of several entomopathogenic fungi strains was evaluated as a potential biocontrol strategy against the European Tarnished Plant Bug: Lygus rugulipennis (fig. 1). Thirty-seven strains from 4 species were screened for their pathogenicity to L. rugulipennis. Strains with the strongest pathogenic activity were retained for further tests,...
The virulence of several entomopathogenic fungi strains was evaluated as potential biocontrol strategy against the green peach aphid Myzus persicae. Thirty-seven strains from 4 species were screened for their activity on Myzus persicae. Strains with the strongest activity were retained for further tests, confirming their aggressiveness against the...
In Quebec, the toxicity of six insecticides was tested in laboratory on Neoseiulus fallacis female, a predatory mite against Tetranychidæ pests in vineyards and orchards. Two insecticides (spinetoram and clothianidin) proved to be toxic for N. fallacis (more than 85 % of mortality) and should’nt be used in Integrated Pest management (IPM); the inse...
Following positive trials in laboratory, six strains of biological control agents on pome fruits were evaluated in reducing post-harvest disease. These strains were tested in biological orchard on two apple and one pear varieties. Our experiment showed the variability of the results obtained in open field. The diversity of moulds at the exit of col...
The tarnished plant bug, Lygus lineolaris (Heteroptera: Miridae), is a highly polyphagous pest that feeds on a broad range of economically important crops in North America. Flying L. lineolaris adults can move from crop to crop rapidly and easily. Little is known about the movement of L. lineolaris in or near vineyards. From May to October 2002 and...
Insecticides are still the single main pest control method employed today by most growers to mitigate damage done by the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois) (Hemiptera: Miridae). In eastern Canada, the complex agricultural ecosystem, which may be described as a mosaic of farmlands dispersed among natural habitats (forest, pr...
Nymphs and adults of the tarnished plant bug (Lygus lineolaris (Palisot de Beauvois)) feeding on grapevine were videorecorded in the laboratory to determine the short-term impact of feeding punctures at various phenological stages. Feeding behaviour was significantly different between nymphs and adults in the number of punctures but not in the feed...
As part of a research project to determine the damage caused by the tarnished plant bug (Lygus lineolaris) in vineyards, we studied the injury caused by feeding on grapevines at bloom (phenological stages H to I). Adults and nymphs (4-5 instars) were video-recorded in laboratory to localize damages. Histological studies, done by light and electroni...
La punaise terne, Lygus lineolaris (Palisot de Beauvois) (Hemiptera : Miridae), est un insecte indigène de l'Amérique du Nord et il s'étend du Mexique à l'Alaska. L. lineolaris est extrêmement polyphage: elle se nourrit sur près de 400 espèces végétales, préférentiellement sur des tissus en pleine croissance (méristèmes) et change fréquemment de pl...

Avec les changements climatiques, diverses espèces exotiques sont susceptibles de s’introduire en Suisse et d’exercer une pression de plus en plus forte. Des régions transfrontalière, comme Genève (Suisse), sont spécialement exposées. Un système de surveillance précoce des ravageurs émergents permettrait de freiner leur dissémination ainsi que leur impact sur le secteur agricole et la biodiversité.
