Biological control of Botrytis cinerea on stem wounds with moderately halophilic bacteria Inra
Sadfi-Zouaoui, N.; Hannachi, I.; Andurand, D.; Essghaier, B.; Boudabous, A.; Nicot, P..
Infection of tomato stem wounds by Botrytis cinerea is an important problem which can cause severe economic losses in greenhouse tomato crops. Three moderately halophilic bacteria were tested for their ability to protect pruning wounds from attacks by B. cinerea under growth chamber conditions. The severity of the disease estimated by the length of the rotted stem was used to calculate the area under the disease progress curves (AUDPC). Bacterial antagonists (B1, B2 and B3) were very effective in controlling Botrytis-infection on the tomato stems during the first 6 days and later by the end of the experiment. Plants treated with Bacillus subtilis (B1) had the lowest AUDPC (0). It was followed by B. subtilis (B3) and Halomonas sp. (B2) with AUDPC of 9.8 and...

Biological control of water hyacinth on Lake Victoria, Kenya OceanDocs
Ochiel, G.R.S.; Mailu, A.M.; Gitonga, W.; Njoka, S.W..
The Kenya Agricultural Research Institute (KARI) imported 12 800 curculionid weevils (Neochetina spp.) from Benin, Uganda, South Africa and Australia for biological control of water hyacinth between 1993 and1998. In 1996, KARI’s rearing and quarantine facility at the National Agricultural Research Centre, Muguga, provided initial “breeding stock” to another rearing facility at the National Fibre Research Centre, Kibos, near Lake Victoria. To date, 36 500 weevils and 42 000 weevil eggs have been produced from Kibos. About 2000 weevils were produced each month from plants grown in plastic basins, galvanized corrugated iron sheet tanks and a polypropylene rearing pool. Between January 1997 and August 1998, KARI released 36 250 Neochetina weevils at 27 sites...

Egg hatching response to a range of air humidities for six species of predatory mites Inra
Ferrero, M.; Gigot, C.; Tixier, M.S.; van Houten, Y.M.; Kreiter, S..
The efficiency of biological control agents is often affected by local conditions such as low relative humidity (r.h.). This is especially true for mites of the family Phytoseiidae, and particularly for their egg stage. A key issue in biological control is thus to assess the drought tolerance of phytoseiid species that are (or that will be) commercialized. In this study, we evaluated the egg hatching response to a humidity range for six species of Phytoseiidae, by assessing the relative air humidity and vapour pressure deficit (VPD) at which 50% of the eggs hatch: r.h.50 and VPD50. Typhlodromus athiasae Porath & Swirskii and Phytoseiulus longipes Evans (Argentinean strain) were the most drought-tolerant, with a r.h.50 of 43% (VPD50 = 18.2 hPa) and 43%...

Estimation du potentiel de résistance de Botrytis cinerea à des biofongicides Inra
Ajouz, S..
La pourriture grise, causée par le champignon Botrytis cinerea, est l'une des principales maladies aériennes fongiques sur diverses cultures d’importance agronomique. La diversité génétique de B. cinerea est très forte et la capacité rapide d’adaptation de ce champignon à une pression sélective est également avérée. Ce champignon est ainsi capable de développer des résistances à une grande variété de composés fongicides de synthèse ou d'origine naturelle. Des méthodes alternatives de lutte ont de ce fait été développées ces dernières années : divers agents de lutte biologique (ALB) présentant différents modes d’actions ont été identifiés et pour certains d’entre eux commercialisés pour contrôler B. cinerea. Cependant la durabilité de la lutte biologique...

Mites and ticks (Acari) Inra
Navajas Navarro, M.; Migeon, A.; Estrada-Peña, A.; Mailleux, A.C.; Servigne, P.; Petanović, R..
The inventory of the alien Acari of Europe includes 96 species alien to Europe and 5 cryptogenic species. Among the alien species, 87 are mites and 9 tick species. Besides ticks which are obligate ectoparasites, 14 mite species belong to the parasitic/predator regime. Among these species, some invaded Europe with rodents (8 spp.) and others are parasitic to birds (2 spp). Th e remaining 77 mite species are all phytophagous and among these 40% belong to the Eriophyidae (37 spp.) and 29% to the Tetranychidae (27 spp.) families. Th ese two families include the most signifi cant agricultural pest. Th e rate of introductions has exponentially increased within the 20th century, the amplifi cation of plant trade and agricultural commodities movements being the...

Mortality of the honey bee, Apis mellifera, in colonies treated with certain biological insecticides National Institute of Agronomic Research
Cantwell, George E.; Knox, David A.; Lehnert, Thor; Michael, A.S..
Candidate insect pathogens were fed at various levels to honey bees (Apis mellifera) either in small cages or in observation hives. The pathogens tested included two polyhedrosis viruses, a granulosis virus, a commercial preparation of Bacillus thuringiensis var. thuringiensis, spores, crystals, and the exotoxin of this variety, plus the crystals of varieties alesti and sotto. No mortality was recorded as a result of treatment with any of these pathogens except with the highest level of the exotoxin of B. thuringiensis.

Pathogenic and beneficial microorganisms in soilless cultures Inra
Vallance, J.; Déniel, F.; Le Floch, G.; Guérin-Dubrana, L.; Blancard, D.; Rey, P..
Soilless cultures were originally developed to control soilborne diseases. Soilless cultures provide several advantages for growers such as greater production of crops, reduced energy consumption, better control of growth and independence of soil quality. However, diseases specific to hydroponics have been reported. For instance, zoospore-producing microorganisms such as Pythium and Phytophthora spp. are particularly well adapted to aquatic environments. Their growth in soilless substrates is favoured by the recirculation of the nutrient solution. These pathogenic microorganisms are usually controlled by disinfection methods but such methods are only effective as a preventive measure. Contrary to biofiltration, active treatments such as UV, heat and...

Phenotypic variation in invasive and biocontrol populations of the harlequin ladybird, Harmonia axyridis Inra
Lombaert, E.; Malausa, T.; Devred, R.; Estoup, A..
Despite numerous releases for biological control purposes during more than 20 years in Europe, Harmonia axyridis failed to become established until the beginning of the 21st century. Its status as invasive alien species is now widely recognised. Theory suggests that invasive populations should evolve toward greater phenotypic plasticity because they encounter differing environments during the invasion process. On the contrary, populations used for biological control have been maintained under artificial rearing conditions for many generations; they are hence expected to become specialised on a narrow range of environments and show lower phenotypic plasticity. Here we compared phenotypic traits and the extent of adaptive phenotypic plasticity in two...

Plant-driven selection of microbes Inra
Hartmann, A.; Schmid, M.; Van Tuinen, D.; Berg, G..
The rhizodeposition of plants dramatically influence the surrounding soil and its microflora. Root exudates have pronounced selective and promoting effects on specific microbial populations which are able to respond with chemotaxis and fast growth responses, such that only a rather small subset of the whole soil microbial diversity is finally colonizing roots successfully. The exudates carbon compounds provide readily available nutrient and energy sources for heterotrophic organisms but also contribute e.g. complexing agents, such as carboxylates, phenols or siderophores for the mobilization and acquisition of rather insoluble minerals. Root exudation can also quite dramatically alter the pH- and redox-milieu in the rhizosphere. In addition, not only...

Vers des cultures fruitières et légumières à hautes performances environnementales Inra
Jeannequin, B.; Dosba, F.; Plénet, D.; Pitrat, M.; Chauvin, J.E..
En France, les productions fruitières et légumières qui occupent moins de 2% de la SAU sont caractérisés par la diversité des espèces cultivées et les multiples systèmes de culture qui peuvent avoir des impacts environnementaux divers. Face aux nouveaux enjeux de développement d’une horticulture sensu lato à haute performance environnementale, l’Inra contribue aux travaux visant à réduire l’impact environnemental de ces cultures et à concevoir des systèmes de culture innovants. Les principaux résultats acquis au cours des dernières années concernent l’optimisation de la gestion du climat sous serre, le raisonnement optimisé de pratiques d’irrigation et de fertilisation, la création de variétés multi résistantes et la gestion durable des résistances aux bio...
