Drosophila suzukii, a threat to strawberry plants in Réunion
In October 2013 Drosophila suzukii was first observed in Reunion. The fruit fly was found in a strawberry field in the south. It was not expected to arrive so soon on the island, but its introduction was seen as extremely likely. 18 months have passed since the fly was first observed. So what is the current situation of Drosophila suzukii in Reunion?

The Asian citrus canker in the Indian Ocean
Fruits early loss, alteration of their external quality and defoliation are symptoms caused by Asian citrus canker. Caused by bacteria of the genus Xanthomonas, the disease can cause up to 50% yield loss on the most sensitive species in the tropics. Due to the severity of the symptoms it induces, it is classed as a quarantine pest in several countries including the USA, Australia & EU with a ban on exports of fresh fruits for producing countries without an effective eradication strategy.
Active epidemiological surveillance of Bacterial wilt in the Indian Ocean
Ralstonia solanacearum is a bacterium responsible for the wilt of a large number of cultivated and wild plants worldwide. Some strains of this bacterium are recognized as a quarantine pest in Europe and potential bioterrorism agent in the US. R. solanacearum can cause the loss of an entire crop and usually leads to the death of the plant.
The islands as "model systems" for research in ecology and evolution
Ben Warren, former biologist with the PVBMT Joint Research Unit (Cirad - University of Reunion Island) and now based at the University of Zurich, recently published in Ecology Letters an article commemorating the 50th anniversary of a fundamental biological study: MacArthur and Wilson’s Theory of Island Biogeography, published in 1963.
(re) Définir la Biodiversité, un enjeu pour l’avenir
« Biodiversité », terme tant et tant employé qu'il tend à être dépossédé de son sens originel. Qu’entend-on derrière ce mot qui nous parait si familier ? La biodiversité englobe une réalité délicate à appréhender, phénomène complexe qu’il importe d’aborder dans sa globalité.
