Multilevel variation in sugar profile of wild figs supports the dispersal syndrome hypothesis

Linh M. N. Nguyen, Helene Witan, Jana Ebersbach, Diary N. Razafimandimby et autres

Plant–frugivore mutualisms are shaped by suites of fruit traits that evolve in tandem with the preferences of seed dispersers, a concept encapsulated by the dispersal syndrome hypothesis. While morphological characteristics (e.g., size, color, firmness) have been extensively studied, the nutritional dimension, and …

The diversity of Ficus

Simon Tristram Segar, Sotiria Boutsi, Daniel Souto‐Vilarós, Martin Volf et autres

BACKGROUND: The influence of Ficus extends beyond its numbers (800 species), and fig trees are often key-stone species in their habitats. Ficus fills many tropical forest niches. The past 15 years have witnessed an explosion of research in Ficus, and its obligate …

Attracting Parasitoids with Service Plants for Biocontrol in the Tropics: Abundance and Taxonomic Diversity Effects

Margot Gumbau, Xavier Fauvergue, Jean-Yves Rasplus, Blazy Jean-Marc

New record of seed beetles of the genus Megabruchidius Borowiec, 1984 (Chrysomelidae: Bruchinae) and associated parasitoids (Hymenoptera: Chalcidoidea) from Bulgaria

Denis Gradinarov, Yana Petrova, Ivaylo Todorov, Miroslav Antov et autres

The Asian seed beetles Megabruchidius dorsalis (Fåhraeus, 1839) and M. tonkineus (Pic, 1904) (Chrysomelidae: Bruchinae) are reported from several new localities in Bulgaria. These species successfully established in the country, but M. dorsalis appears to be more common and more abundant than …

New genera of Afrotropical Chalcidoidea (Hymenoptera: Cerocephalidae, Epichrysomallidae, Pirenidae and Pteromalidae)

Mircea‐Dan Mitroiu, Jean-Yves Rasplus, Simon van Noort

As a preliminary step towards the development of a key to genera of several families of Afrotropical Chalcidoidea, seven new genera in four families are described: Cerocephalidae–Milokoa Mitroiu, gen. nov. (type species: Milokoa villemantae Mitroiu, sp. nov.); Epichrysomallidae–Delvareus Rasplus, Mitroiu & van …

Ooctonus vulgatus (Hymenoptera, Mymaridae), a potential biocontrol agent to reduce populations of Philaenus spumarius (Hemiptera, Aphrophoridae) the main vector of Xylella fastidiosa in Europe

Xavier Mesmin, Marguerite Chartois, Guénaëlle Genson, Jean‐Pierre Rossi et autres

As vector of Xylella fastidiosa (Wells, 1987) in Europe, the meadow spittlebug, Philaenus spumarius (Linnaeus, 1758) (Hemiptera: Aphrophoridae) is a species of major concern. Therefore, tools and agents to control this ubiquitous insect that develops and feeds on hundreds of plant species …

Pushing the limits of whole genome amplification: Successful sequencing of RADseq libraries from single micro-hymenoptera (Chalcidoidea, Trichogramma)

Astrid Cruaud, Géraldine Groussier, Guénaëlle Genson, Laure Sauné et autres

A major obstacle to high-throughput genotyping of micro-hymenoptera is their small size. As species are difficult to discriminate and because complexes may exist, the sequencing of a pool of specimens is hazardous. Thus, one should be able to sequence pangenomic markers (e.g. …

Using Insects To Detect, Monitor And Predict The Distribution Of Xylella Fastidiosa: A Case Study In Corsica

Jean-Yves Rasplus, Astrid Cruaud, Anne‐Alicia Gonzalez, Martin Godefroid et autres

We sampled ca 2500 specimens of Philaenus spumarius throughout Corsica without a priori on the presence of symptoms on plants. We screened 448 specimens for the presence of Xylella fastidiosa (Xf) using qPCR and a custom nested PCR. qPCR appeared versatile and …
