Bark and Wood Boring Insects in Living Trees in Europe, a Synthesis
TLDR
General Conclusions and Research Priorities for Bawbilt Organisms in Europe.
Invasive alien predator causes rapid declines of native European ladybirds
TLDR
This study compares the distribution and abundance of formerly common and widespread native ladybirds before and after the arrival of Harmonia axyridis, a globally rapidly expanding IAS.
The Chemical Ecology of Defense in Arthropods
Long-distance dispersal and human population density allow the prediction of invasive patterns in the horse-chestnut leafminer Cameraria ohridella
TLDR
Among these models, the stratified dispersal model incorporating the effect of human population density provides the best description of the spread of Cameraria ohridella in Germany in predictive and qualitative terms.
Research on Parasitoids and Predators of Scolytidae – A Review
TLDR
This review will focus primarily on parasitoids and predators of bark beetle species considered to be pests of living trees in Europe, although it may also consider relevant research in other continents.
Damage and Control of Bawbilt Organisms an Overview
TLDR
The most frequently cited species is identified, statistics per country are provided and the data available on the "top ten" species are analysed, i.e. those species that were scored +++ for aggressivity at least three times.
Rapid increase in dispersal during range expansion in the invasive ladybird Harmonia axyridis
TLDR
The hypothesis of an increase in dispersal capacity with range expansion in Harmonia axyridis, a ladybird that has been invading Europe since 2001 is tested and a marked increase in the flight speed is found from the core to the front of the invasion range in two independent sampling transects.
Harmonia+ and Pandora+: risk screening tools for potentially invasive plants, animals and their pathogens
TLDR
The Harmonia+ framework presented here brings together 30 questions that refer to distinct components of invasion that cover the stages of introduction, establishment, spread, and multiple kinds of impacts, viz. referring to the health of the environment, cultivated plants, domesticated animals and man.
Forecasting Cameraria ohridella invasion dynamics in recently invaded countries: from validation to prediction
TLDR
The model and predictions developed provide one of the few examples of an a priori model of invasion in a newly invaded country, and provide a simple modelling framework that can be used to explore the spread of other invading organisms.
Spatial Distribution of Ambrosia-Beetle Catches: A Possibly Useful Knowledge to Improve Mass-Trapping
TLDR
Several species of ambrosia beetles have recently started attacking standing, living beeches in southern Belgium, and so far the outbreak has been limited to the Ardenne, and partly the Gaume, areas, and Brussels has been untouched.
