Species diversity of larval parasitoids of the European grapevine moth (Lobesia botrana, Lepidoptera: Tortricidae): the influence of region and cultivar.
7 pages; International audience; The European grapevine moth, Lobesia botrana (Denis & Schiffermüller, 1775) (Lepidoptera: Tortricidae) is a major pest of grapevines responsible for great economic losses and frequent insecticide applications. Nevertheless, the use of parasitoids as potential biological control agents has received very little attention. In this study, we present results from a survey on parasitoid species collected from French and Swiss vineyards over a period of 2 years. Over 2000 larvae of L. botrana were collected from six grape cultivars out of which a total of 118 parasitoids emerged. Ten species were identified. Exochus notatus (Holmgren, 1858) (Hymenoptera: Ichneumoni…

Control of grape berry moth larvae using parasitoids: should it be developed?
8 pages; International audience; Besides mating disruption techniques and progress in monitoring techniques (e.g. theuse of food traps against females), biological control may reveal itself very efficient at controllinggrape moth populations. Parasitoids active to control grape moths are known for long invineyards; few of them were already described in the middle of the 19th century in Frenchvineyards and their efficiency was already recognized especially against the diapausing and thefirst spring generations of the moths. Rather numerous attempts to release egg parasitoids havebeen done in different European countries using different species of trichogrammas. The resultsobtained varied a l…
Charipinae Dalla Torre & Kieffer, 1910 (Hymenoptera: Cynipoidea: Figitidae) from the Mercantour National Park (Alpes-Maritimes, France), with descriptions of three new species
ABSTRACT Charipinae Dalla Torre & Kieffer, 1910 material collected during the ATBI of the Mercantour National Park in the Alpes-Maritimes (France) has been studied. Based on the study of 362 specimens, 35 species in four genera have been identified from: 23 Alloxysta Forster, 1869; 10 Phaenoglyphis Forster, 1869; one Apocharips Fergusson, 1986 and one Dilyta Forster, 1869. Of these, 19 species are recorded from France for the first time: Alloxysta abdera Fergusson, 1986; Alloxysta arcuata (Kieffer, 1902); Alloxysta brachycera Hellen, 1963; Alloxysta brevis (Thomson, 1962); Alloxysta fracticornis (Thomson, 1862); Alloxysta mullensis (Cameron, 1883); Alloxysta pilipennis (Hartig, 1840); Allox…
