Among today's many biological control strategies, classical biological control (CBC) is the oldest – it dates back to the nineteenth century, which explains its name. This biological control method is based on the intuitive idea that fighting an invasive population requires finding a natural enemy from its native range. CBC is therefore closely...

En 2010, l'UMR « Institut Sophia Agrobiotech » s'est doté d'un nouveau bâtiment d'élevage pour les insectes réglementés, « Entomopolis ». Ce document a pour objectif de décrire cette infrastructure et de partager l'expérience acquise en ce qui concerne la maintenance, l'utilisation et l'évolution de la zone dédiée à des activités de RDLB...

On south-west Indian Ocean islands, many crops and ornamental plants are threatened by the spiralling whitefly Aleurodicus dispersus (Hemiptera: Aleyrodidae), which is a polyphagous pest that is native to the Caribbean region. Aleurodicus dispersus causes economic damage to various crops on all the islands in the south-west Indian Ocean. The...

Ophelimus sp. (Hym: Eulophidae) is an Australian gall wasp newly found in Southern Europe forming galls on Eucalyptus globulus. A congeneric gall wasp O. maskelli, also established in the Mediterranean Basin, is currently controlled by the introduced parasitoid Closterocerus chamaeleon. To date, no parasitism was observed on Ophelimus sp. by C....

In response to the introduction and spread of the chestnut gall wasp Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae) in metropolitan France, including Corsica, the exotic parasitoid Torymus sinensis Kamijo (Hymenoptera: Torymidae) was deliberately introduced in more than 50 locations covering most of the areas of chestnut production....

Insecticide toxicity may strongly vary with temperature, and interspecific differences have been commonly reported for this relationship. A differential influence of temperature on insecticide toxicity between pests and their natural enemies may have important consequences on biological control in a global warming context. This study aimed to...

A bstract The rise of the Asian chestnut gall wasp Dryocosmus kuriphilus in France has benefited the native community of parasitoids originally associated with oak gall wasps by becoming an additional trophic subsidy and therefore perturbing population dynamics of local parasitoids. However, the successful biological control of this pest has...

We report here the first observation of Zaprionus indianus Gupta in mainland France. Five specimens of both sexes were trapped in a liquid vinegar bait in Cap d'Antibes (French Riviera) and their taxonomic identification was then performed by morphologi-cal and molecular analysis. Z. indianus is recognized as a fig pest in the invaded American...

The spotted wing Drosophila, Drosophila suzukii (Ds), became a major economic pest for fruit production since its establishment in Europe and America. Among potential control methods, only classical biological control appears to be a mean of sustainably regulating Ds in both cultivated and natural habitats. In the frame of risk assessment,...

Considered as a major pest of Castanea species worldwide, the chestnut gall wasp Dryocosmus kuriphilus Yasumatsu (Hymenoptera, Cynipidae) can induce fruit production losses of 60-80%. Reported for the first time in Italy in 2002, this pest is now widespread across the French distribution of chestnut trees.Based on successful attempts in other...

Context : Considered as one of the most important pest of Castanea species worldwide, the chestnut gall wasp Dryocosmus kuriphilus (Hymenoptera,Cynipidae) can induced fruit production losses from 60 to 80% (EFSA, 2010). Reported for the first time in Europe in 2002 in Italy (Brussino et al., 2002), this pest was detected in France in 2007 and...

The systematics of the European species of Eupelmus (Eupelmus) Dalman (Hymenoptera: Eupelmidae) belonging to the urozonus-complex' is elucidated through combined molecular and morphological characterization. One mitochondrial gene fragment (Cytochrome oxidase I) and one nuclear protein-coding gene fragment (Wingless) were sequenced and the...

Abstract Uncertainty about the taxonomic status and the specificity of a species commonly prevent its consideration as a candidate for biological control of pest organisms. Here we use a combination of molecular analysis and crossing experiments to gather evidence that the parasitoid wasp Ganaspis brasiliensis , a candidate for biological...

This paper is an addendum for the availability of the names of 11 new species proposed in Al khatib et al. (2014).

Native to China, the chestnut gall wasps Dryocosmus kuriphilus Yasumatsu (Hymenoptera, Cynipidae) has invaded several countries on three continents in about half a century. To reduce the negative impact on the chestnut industry, the hymenopteran parasitoid Torymus sinensis Kamijo (Hymenoptera, Torymidae) was firstly translocated from China to...

We report here for the first time the presence of Ophelimus mediterraneus sp. n. in Mediterranean Europe. This species appears to be closely related to Ophelimus maskelli, a well-known invasive pest of Eucalyptus. Based on molecular (cytochrome oxidase I, 28S), morphological (multivariate ratio analysis) and bio-ecological investigations, our...

The olive fruit fly, Bactrocera oleae (Dipt., Tephritidae), is the most important pest of olive crops in the world. Economic losses associated to the limited efficiency of pesticides and natural regulation require the development of new alternatives. A classical biological control program was thus implemented in 2007 in France with two main...
