Il y a deux mois, Phytoma évoquait la protection des cultures de tomate contre la mineuse de la tomate Tuta absoluta. Il en ressortait que, pour réussir cette protection, il fallait intégrer plusieurs moyens dont des auxiliaires parasitoïdes (Tabone et al., 2012). L'article citait le projet CASDAR « T utaPI » financé par le Ministère de...

Le nouveau ravageur des tomates, Tuta absoluta, peut provoquer des dégâts considérables s'il n'est pas efficacement contrôlé, et ce, dès le début des infestations. La stratégie de lutte actuelle en protection intégrée repose essentiellement sur la prophylaxie, la capacité des punaises mirides lâchées contre les aleurodes à se nourrir aux dépens...
The South American tomato leafminer, Tutu absoluta Meyrick (Lepidoptera: Gelechiidae); is a major pest that has recently invaded Afro-Eurasia. Biological control, especially by Trichogramma parasitoids; is considered to be promising as a management tool for this pest. However, further development: of Trichogramma-based biocontrol strategies...

High-density rearing conditions for the mass-production of biological control agents are known to affect individual quality and performance. However, complex phenotypic traits like dispersal behaviour and their response to rearing conditions are rarely investigated, although they are likely to affect directly biocontrol efficiency in the field....

1. The proximate behavioural rules adopted by parasitoid females to manage their foraging time on patches of hosts were studied, under standardized laboratory conditions, in different species (and populations) of the Trichogrammatidae (Hymenoptera) family. 2. Seventeen species/populations were compared and the behavioural mechanisms adopted by...
The South American tomato pinworm (Tuta absoluta) has recently invaded Europe and is rapidly spreading in the Afro-Eurasian continent where it is becoming a major pest on tomato crops. Laboratory tests were undertaken to evaluate the potential of 29 European strains of Trichogramma parasitoids to control T. absoluta. In addition to the host...
The both tree moth ([i]Cydalima perspectalis[/i]) has recently appeared in Europe (2008 in France) causing significant damages to box trees, ornamental plants particularly popular in gardens. Nowadays, the few treatments used are essentially chemicals, bioinsecticides or traps. The national project SaveBuxus has been created in order to find...
This study is the first step of the TutaPI program (2011–13) to decrease the costs of Integrated Pest Management (IPM) strategies against Tuta absoluta in France by investigating new beneficial insects. Currently, the association of predator/egg parasitoid (Macrolophus pygmaeus and Trichogramma achaeae, respectively) in IPM strategies are quite...
In the framework of biological control, the selection of effective natural enemies determines the final pest control. Thus, the genetic improvement of biocontrol agents could enhance the efficiency of biocontrol programs. Although promising, this approach has rarely been applied in this field. At the intraspecific level, hybridization between...

The Lepidopteran pest of tomato, Tuta absoluta, is native to South America and is invasive in the Mediterranean basin. The species' routes of invasion were investigated. The genetic variability of samples collected in South America, Europe, Africa and Middle East was analyzed using microsatellite markers to infer precisely the source of the...

Dans le cadre de la protection contre Tuta absoluta (projet TutaPI), nous présentons les principaux résultats obtenus. L'objectif est d'améliorer les moyens de biocontrôle actuellement commercialisés, par la recherche d'un nouvel auxiliaire endémique, afin d'augmenter l'efficacité et diminuer les coûts de la protection
