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 ...

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 ...

Short-term Thermal Changes Affect Parasitism on Asian Chestnut Gall Wasp [PDF]
, 2020 Thermal variations affect tri-trophic interactions involving plants, herbivores, and parasitoids, causing a mismatch between their phenological cycles. In the current environmental context of climate change, climatic factors can undergo profound and sudden changes, such as sudden hot or cold snaps.

Impact of the Asian Chestnut Gall Wasp, Dryocosmus kuriphilus (Hymenoptera, Cynipidae), on the Chestnut Component of Honey in the Southern Swiss Alps [PDF]
Journal of Economic Entomology, 2017 The Asian chestnut gall wasp (ACGW; Dryocosmus kuriphilus Yasumatsu, Hymenoptera, Cynipidae) is considered as one of the most dangerous pests of the genus Castanea. In southern Switzerland, repeated heavy ACGW attacks prevented chestnut trees from vegetating normally for years before the arrival and spread of the biological control agent Torymus ...

Host Gall Size and Temperature Influence Voltinism in an Exotic Parasitoid
Frontiers in Ecology and Evolution, 2022 Insect phenology is highly temperature-dependent. Higher temperatures can lead to earlier emergence and lengthening of the active period, which enable many insect groups to complete more generations.

Gnomoniopsis castaneae: An emerging plant pathogen and global threat to chestnut systems
Plant Pathology, Volume 72, Issue 2, Page 218-231, February 2023., 2023 The recent discovery of Gnomoniopsis castaneae in the United States brings a new urgency to the need to understand the full range and epidemiology and to examine potential methods of detection and mitigation. Abstract Gnomoniopsis castaneae is an important, destructive pathogen of Castanea species, initially identified as the primary agent of nut rot ...

Evolution, Volume 76, Issue 8, Page 1849-1867, August 2022., 2022 Abstract Quantifying the frequency of shifts to new host plants within diverse clades of specialist herbivorous insects is critically important to understand whether and how host shifts contribute to the origin of species. Oak gall wasps (Hymenoptera: Cynipidae: Cynipini) comprise a tribe of ∼1000 species of phytophagous insects that induce gall ...
