Egg maturation in an invasive gall wasp, Dryocosmus kuriphilus (Hymenoptera: Cynipidae): An experimental test of the pro-ovigenic and facultatively synovigenic hypotheses

European Journal of Entomology, 2022
There are two hypotheses on egg maturation in the invasive chestnut gall wasp, Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae). That it is pro-ovigenic (most or all of its potential lifetime egg complement is mature upon emergence) or ...

Distribution, causal agents, and infection dynamic of emerging ink disease of sweet chestnut in Southern Switzerland

Environmental Microbiology, Volume 25, Issue 11, Page 2250-2265, November 2023., 2023
Abstract Emerging diseases caused by both native and exotic pathogens represent a main threat to forest ecosystems worldwide. The two invasive soilborne pathogens Phytophthora cinnamomi and Phytophthora × cambivora are the causal agents of ink disease, which has been threatening Castanea sativa in Europe for several centuries and seems to be re ...

Studies on the resistance of chestnut trees to chestnut gall wasps II

Engei Gakkai zasshi, 1968
1. Host tissues such as young leaves or stipules of chestnut trees around larva began to grow misshapenly, envelop the parasite and form galls from late July. In late August, gall tissues embraced the wasp commpletely to build a larval cavity. Since this period, in susceptible varieties individual gall became to adhere each other and more advanced ...

Factors influencing short‐term parasitoid establishment and efficacy for the biological control of Halyomorpha halys with the samurai wasp Trissolcus japonicus

Pest Management Science, Volume 79, Issue 7, Page 2397-2414, July 2023., 2023
High parasitization of Trissolcus japonicus on Halyomorpha halys recorded at release and adventive sites. Both species are favored by the same landscape elements, mediating risk for nontarget species. Abstract BACKGROUND Classical biological control has been identified as the most promising approach to limit the impact of the invasive pest species ...

The open bar is closed: restructuration of a native parasitoid community following successful control of an invasive pest

Peer Community Journal, 2021
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
