Establishment of oak processionary moth Thaumetopoea processionea (Lepidoptera: Notodontidae) in Odense, Denmark

EPPO Bulletin, EarlyView.
Abstract The oak processionary moth (Thaumetopoea processionea) has recently established a significant presence in Odense, Denmark, a city characterized by its substantial population of oak trees. This study provides details on the current situation (as of April 2025), examines potential introduction pathways, and outlines the challenges associated ...

Influence of meteorological conditions and crown defoliation on tree phenology in intensive forest monitoring plots in Slovenia

Acta Silvae et Ligni, 2014
Data from the forest monitoring programme in Slovenia were used to assess the relationship between tree phenology, crown defoliation and meteorological conditions in Fagus sylvatica, Quercus robur and Picea abies forests in the 2004-2013 period.

Fly me to the canopy: Diptera communities in oak forest crowns as bioindicators of stand decline

Insect Conservation and Diversity, EarlyView.
Diptera diversity: Oak decline increases the overall Diptera diversity, particularly in saproxylic and floricolous guilds, likely due to more open canopies and greater deadwood and floral resource availability. Family responses: Dolichopodidae, Empididae, Hybotidae and Anthomyiidae thrive in declining stands, whereas Mycetophilidae and other fungus ...

Genome assembly of Elcysma westwoodi provides insights into host‐plant cyanogenic glucoside detoxification and chemical defence gene evolution

Insect Molecular Biology, EarlyView.
A chromosome‐level genome of Elcysma westwoodi was assembled. The genome encodes 272 detoxification‐related genes. A single‐copy bCAS was retained for cyanide detoxification. CYP405A and CYP332A were recruited into cyanogenic defence evolution. UGT33A retained a conserved GT‐B fold and catalytic domains.

Temperate tree species show cross‐tolerance to heat, drought, and late spring‐frost stress

New Phytologist, EarlyView.
Significant cross‐tolerance of leaf traits to heat, drought and late spring‐frost were found. (a) Turgor loss point vs lethal spring‐frost temperature. (b) Heat thermal threshold temperature vs lethal spring‐frost temperature. (c) Heat thermal threshold temperature vs turgor loss point.

Genomic loci associated with leaf abscission contribute to machine picking and environmental adaptability in upland cotton (Gossypium hirsutum L.)

Journal of Advanced Research
Introduction: Defoliation by applying defoliants before machine picking is an important agricultural practice that enhances harvesting efficiency and leads to increased raw cotton purity.
