  author={Bernard Vercambre and O. Goebel and Guy Riba and Gilles Morel and Paul Robert and Micha{\"e}l Guillon},
Probablement introduit de Madagascar a la Reunion en 1972, signale comme ravageur des principales cultures de l'ile (canne a sucre, geranium, culture legumieres, prairies ...) en 1981, Hoplochelus marginalis (Coleopt. Melolonthinae) a fait l'objet d'une lutte biologique basee sur l'emploi : (i) d'entomophages : introduction d'Hymenopteres Scoliidae tels Campsomeris spp. et Tiphia parallela; (ii) d'entomopathogenes appartenant a des classes aussi diverses que bacteries, champignons, virus… 
Description and phylogenetic placement of Beauveria hoplocheli sp. nov. used in the biological control of the sugarcane white grub, Hoplochelus marginalis, on Reunion Island
The Reunion Island fungus is described as the new species B. hoplocheli after it was revealed that these strains, previously identified as Beauveria brongniartii, did not match that species and are closely related to but still distinct from B. malawiensis strains.
Multi locus analysis of Pristionchus pacificus on La Réunion Island reveals an evolutionary history shaped by multiple introductions, constrained dispersal events and rare out‐crossing
periodic out‐crossing generates admixture between genetically diverse lineages, creating a diverse array of allelic combinations likely to increase the evolutionary potential of the species and facilitate adaptation to local environments and beetle hosts.
Haplotype diversity of the nematode Pristionchus pacificus on Réunion in the Indian Ocean suggests multiple independent invasions.
It is described the first account of soil- and beetle-associated nematodes on an island setting by investigating the island of Reunion in the Indian Ocean, establishing Reunion as a case study for nematode island biogeography, in which the analysis of nematODE population genetics and population dynamics can provide insight into evolutionary and ecological processes.
Natural variation in chemosensation: lessons from an island nematode
It is suggested that divergence in odor-guided behavior in P. pacificus may have an important ecological component as nematodes show significant differences in their response to various chemicals and are able to chemotax to live beetles in a novel assay.
Identification of group-I introns in the 28s rDNA of the entomopathogenic fungus Beauveria brongniartii
The length of the 28s ribosomal DNA differs significantly between two strains of the entomopathogenic fungus Beauveria brongniartii, and one of the insertions has been cloned and sequenced and shown to possess all the characteristic sequences and secondary structures of a group-IC intron.
Biological control of weevils and whitegrubs on bananas and sugarcane in the Caribbean.
This review examines the major weevil and whitegrub pests on bananas and sugar-cane of present economic concern in the Caribbean, as well as the various categories of biocontrol agents. It discusses
