Presentation

The BRC “Egg Parasitoids Collection” (BRC EP-Coll) is devoted to "egg (=oophagous) parasitoids" i.e. insects whose pre-imaginal development (before the adult stage) is done inside and to the detriment of a host egg which is killed.

The BRC EP-Coll not only takes place in the continuity of long-term research on Trichogramma at INRAE (1973: creation of Voegele’s laboratory, 1985: Commercialization of T. brassicae, etc.) but also considers egg parasitoids as a strategic stake for biological control or for more academic research.

Beyond the "routine" conservation of strains, this thus requires to set up a collective organization and federate complementary scientific, technical and organizational skills.

While the objective of EP-Coll is, on a longer term, to cover several families and genera of oophagous parasitoids, short-term activities focus mainly on the genus Trichogramma. Trichogramma is already one of the first commercial markets for biological control using macro-organisms (Smith 1996, Consoli et al., 2010) and is a potential source of new biological control agents against lepidopteran pests (Figueiredo et al., 2015, Uelese et al., 2014). Because of their short generation time, their small size and the simplicity of their breeding (well-controlled use of surrogate hosts), they are also used as a biological model in the context of evolutionary ecology (Wajnberg et al., 2000). Benvenuto et al., 2012 and Vercken et al., 2015).
