An established population of Thrips hawaiiensis (Morgan) (Thysanoptera: Thripidae), a species originating from Asia and the Pacific, is reported for the first time in the Western Palaeartic zone (in the South of France). Notes relating to the current geographical distribution, identification, biology and risk of establishment of this potentially invasive species in Europe are provided.
Fruit flies (Diptera, Tephritidae) are amongst the most important pests on fruits and vegetables worldwide. All non‐European Tephritidae are listed in Annex I/A1 of Directive 2000/29/EC but only a limited number of species are regularly intercepted in Europe. This study presents a morphological identification key, supported by molecular analysis, for the third‐instar larvae of 10 commonly intercepted taxa. The key proved to be sensitive and specific. However, the evaluation of its reproducibility emphasizes the importance of the operator's taxonomic expertise and questions the relevance of criteria under which a morphological method can be validated. This morphological identification key provides a rapid and economic diagnostic tool for identifying tephritid larvae. It is not intended to cover all species but allows for an initial diagnosis to be made. Given the current difficulty in identifying most immature stages of insects, the approach presented here could be used to develop some morphological identification tools for other species of concern.
The introduction and spread of Drosophila suzukii (Diptera, Drosophilidae) in Europe has had a major impact on agricultural production. The origin of this pest is known, but not the relative importance of the main pathways of entry and spread. Drosophilid larvae may be detected during phytosanitary import inspections, and this study attempted to identify 18 larvae, originating from 8 countries, intercepted by phytosanitary inspectors in France (mainland and overseas territories). Given the difficulties in identifying larval stages using morphology, molecular analysis was carried out on the larvae. While the authors expected that the larvae would be mainly from the genus Drosophila, in fact the majority were from the genus Zaprionus (14 specimens, 78% of the analysis). These included Zaprionus indianus and Zaprionus tuberculatus which were found 7 times (39%) and 3 times (17%), respectively. New host plants are recorded for Zaprionus tuberculatus.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
