| Background: Invasion of the mosquito salivary glands by Plasmodium is a critical step for malaria transmission. From a SAGE analysis, we previously identified several genes whose expression in salivary glands was regulated coincident with sporozoite invasion of salivary glands. To get insights into the consequences of these salivary gland responses, here we have studied one of the genes, PRS1 (Plasmodium responsive salivary 1), whose expression was upregulated in infected glands, using immunolocalization and functional inactivation approaches. Methodology/Principal Findings: PRS1 belongs to a novel insect superfamily of genes encoding proteins with DM9 repeat motifs of uncharacterized function. We show that PRS1 is induced in response to Plasmodium, not... |

| Les invasions biologiques offrent la possibilité d’appréhender des processus écologiques et évolutifs majeurs, se produisant à de larges échelles spatiales et temporelles. La génétique de l’invasion permet ainsi d’étudier les facteurs historiques et évolutifs favorisant l’expansion des espèces introduites. Avec l’aide de marqueurs microsatellites, nous avons analysé la diversité génétique et la structuration géographique de populations de deux insectes Hyménoptères exotiques dans les cédraies françaises: Megastigmus schimitscheki (en expansion géographique) et M. pinsapinis (distribution géographique stabilisée). Nous avons montré que ces deux espèces ont connu un goulot d’étranglement lors de leur introduction. Les données génétiques et historiques ont... |

| The seeds of both cedar-of-Lebanon (Cedrus libani) and Cyprus cedar (Cedrus brevifolia) are attacked in their natural range by a specialised chalcid, Megastigmus schimitscheki. From 1995 to 1999, seeds were screened for insect damage in the main cedar plantations of southern France, as well as in the stands where cedar is mixed with firs (Abies spp.). X-rays were used to identify chalcid-infested seeds from which the insects were then reared. The surveys revealed the presence of M. schimitscheki in all the stands of Atlas cedar, Cedrus atlantica, planted at Mt Ventoux, southeastern France. The chalcid also infested seeds of an exotic fir, Abies pinsapo, planted in the same area. However, it has not yet reached the cedar plantations in southwestern France,... |

| The project aimed at contributing to understand the ecological and genetic mechanisms underlying the possibilities of establishment of exotic insects in the genus Megastigmus (Hymenoptera: Torymidae), specialized in the exploitation of forest seeds, and at defining suitable methods of monitoring and management of the invasive insect populations. For that, we intended to compare two distinct models host seed/ Megastigmus, crossing different first date of invasion and taxonomic structure of the forests: (i) true firs (Abies)/Megastigmus where the resource, indigenous, is exploited by a native species, M. suspectus, in competition with at least 5 invasive species of North American origin, and (ii) true cedars (Cedrus)/Megastigmus where the resource, itself... |
