Temporal and spatial propagule deposition patterns of the emerging fungal pathogen of chestnut Gnomoniopsis castaneae in orchards of north‐western Italy

Plant Pathology, Volume 70, Issue 9, Page 2016-2033, December 2021., 2021
Rising temperatures and wind gusts increase the propagule deposition rates of the fungal plant pathogen Gnomoniopsis castaneae. Abstract Two chestnut (Castanea sativa) orchards of north‐western Italy were sampled with passive spore traps 35 times over 24 months.

Gnomoniopsis castaneae associated with Dryocosmus kuriphilus galls in chestnut stands in Sardinia (Italy)

iForest - Biogeosciences and Forestry, 2017
Invasive fungal pathogens and pests of sweet chestnut (Castanea sativa Mill.) forests drastically reduce their productivity. The recently described Gnomoniopsis castaneae is one of the main agents involved in the epidemic of brown rot of chestnut nuts ...

Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae) in Minho (Northern Portugal): Bioecology, Native Parasitoid Communities and Biological Control with Torymus sinensis Kamijo (Hymenoptera: Torymidae)

Agronomy, 2022
The Asian chestnut gall wasp Dryocosmus kuriphilus Yasumatsu, native to China, was first detected in Europe in Italy in 2002. In Portugal it was declared in 2014, and it has since affected the Portuguese chestnut production.

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 ...

Torymus sinensis Kamijo, a biocontrol agent against the invasive chestnut gall wasp Dryocosmus kuriphilus Yasumatsu in Spain: its natural dispersal from France and the first data on establishment after experimental releases

Forest Systems, 2019
Aim of study: The globally invasive gall wasp, Dryocosmus kuriphilus Yasumatsu, 1951 (Cynipidae: Cynipini), reached Spain seven years ago and is already regarded as an important pest of chestnuts (Castanea spp.) in this country as well as worldwide.

Molecular species delimitation of the Asian chestnut gall wasp biocontrol agent released in Italy

Insect Systematics & Evolution, 2019
Molecular species recognition and identification, based on the mitochondrial cox1 and on the nuclear ITS2, were performed on individuals of Torymus sinensis collected in Italy, on its close relative T. beneficus and on native torymids. The automatic-gap-discovery (ABGD) analyses correctly separate almost all morphospecies.

Control potentials of some entomopathogenic nematodes against Asian chestnut gall wasp, Dryocosmus kuriphilus Yasumatsu, 1951 (Hymenoptera: Cynipidae)

Turkish Journal of Entomology, 2020
The Asian chestnut gall wasp, Dryocosmus kuriphilus Yasumatsu, 1951 (Hymenoptera: Cynipidae), has spread rapidly worldwide and can cause 80% product loss in chestnut. In the chemical control insecticides are ineffective because the larvae of the insect are well protected inside the chestnut galls. Various parasitoids of D.
