from the western Palaearctic Region to beyond tuta absoluta 10 years after invading europe
Journal of Pest Science, 2017Co-Authors: Mateus R Campos, Antonio Biondi, Abhijin Adiga, R N C Guedes, Nicolas DesneuxAbstract:The South American tomato pinworm, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), is a devastating pest currently threatening the global tomato industry worldwide. In the last 10 years, it has spread and expanded to most of Europe, Africa and Asia, causing extensive damage to the crop itself and to the international tomato trade. With the aim of providing an overview of the current knowledge on this pest, we have briefly reviewed the available literature relying on its spread, quarantine, modeling and management. Finally, we have underlined the gaps in knowledge and provided several recommendations on how to achieve sustainable control as well as how to prevent further spread into unaffected areas.

biology and developmental strategies of the Palaearctic parasitoid bracon nigricans hymenoptera braconidae on the neotropical moth tuta absoluta lepidoptera gelechiidae
Journal of Economic Entomology, 2013Co-Authors: Antonio Biondi, Nicolas Desneux, Edwige Amiensdesneux, Gaetano Siscaro, Lucia ZappalaAbstract:During the years after the invasion of Western Palaearctic tomato crops by the South American tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), several indigenous generalist parasitoids have been recorded on this new host. Among these, Bracon nigricans Szepligeti (Hymenoptera: Braconidae) is widely distributed in the Palaearctic Region, and has been frequently recovered from South American tomato leafminer. However, most of the available data on this species deal with taxonomic aspects and its recovery in faunistic surveys. The current study documents the biology of B. nigricans on South American tomato leafminer, and provides a scientific basis for its inclusion in South American tomato leafminer management programs in Afro-Eurasia. We studied several B. nigricans life-history traits relevant to juvenile development and reproduction by females. B. nigricans proved to be an idiobiont and a synovigenic ectoparasitoid of mature South American tomato leafminer larvae. Several B. nigricans reproductive traits were influenced by the age of the mothers; on average, the progeny had a slightly male-biased sex ratio (60% males) and a low rate of successful development (≈37%). Adult females lived 42.8 d and produced an average of 29.8 offspring. These biological parameters yielded an intrinsic rate of increase of 0.052. Females showed behavioral plasticity in host use, as initial host paralysis was followed by host-feeding, oviposition, or host rejection, with a consequent high mortality rate among hosts exposed to parasitism. Although further field studies are needed, these data, obtained in laboratory conditions, suggest that B. nigricans should be considered as a potential biological control agent of in newly invaded areas of the Palaearctic Region.

Phylogeography of the striped field mouse, Apodemus agrarius (Rodentia: Muridae), throughout its distribution range in the Palaearctic Region
'Springer Science and Business Media LLC', 2020Co-Authors: Latinne Alice, Navascués Miguel, Pavlenko Marina, Kartavtseva Irina, Ulrich, Rainer G., Tiouchichine Marie-laure, Catteau Gilles, Sakka Hela, Quéré Jean‐pierre, Chelomina GalinaAbstract:International audienceTo better understand the evolutionary history of oriental wildlife newcomers in Europe, we studied the phylogeography and demographic history of the striped field mouse, Apodemus agrarius, throughout its Palaearctic distribution area. Genetic datasets including cytochrome b gene sequences and microsatellite markers were analysed using a large range of population genetics methodologies, including coalescent models and approximate Bayesian computations. Our results showed high mitochondrial genetic homogeneity among A. agrarius populations throughout the Palaearctic Region, but microsatellite markers detected a finer population structure with the genetic differentiation of populations from the Eastern and Western distribution ranges. The Western colonisation likely originated from Far East Russian populations during one of the last interglacials. After their colonisation of the Central Asia and Western Regions, the Central Palaearctic populations became isolated from their Eastern relatives. Our coalescent-based approaches suggested a separation between these two distribution ranges around 38 kya or more recently (around 11 kya). Limited gene flow still happened between populations in the two main distribution ranges, mainly from the Eastern to Western populations. Our study, for the first time, provides an overview of the evolutionary and demographic history of the striped field mouse throughout the Palaearctic Region. A. agrarius appears to be an Asiatic immigrant and a relatively new member of the European fauna community. This study further confirms the important role of Far East Asian Regions as a source of European biodiversity
