Vespa velutina: a menace for Western Iberian fruit production

The Asian Hornet (Vespa velutina) is an invasive species that causes severely negative impacts on the ecosystems’ functioning, human health and agriculture. Its impact extends to the detriment of orchards and vineyards as the species feeds on fruits to obtain sugar, consequently diminishing the marketable yield and reducing the overall quantity of final products. The survey presented in this manuscript aimed to...

Do dominant native ants outcompete the invasive Argentine ant in Mediterranean ...

The invasive Argentine ant (Linepithema humile) poses a significant threat to ecosystem stability worldwide. In Mediterranean citrus ecosystems, its spread may be limited by interactions with dominant native ant species. We conducted laboratory experiments to investigate the competitive dynamics between Argentine ants and two major native species, Tapinoma nigerrimum and Lasius grandis. At the individual level,...

Widespread experimental evidence of Allee effects in insects: a meta-analysis

During the last two decades there has been growing recognition of the importance of Allee effects in population dynamics and applied ecology. The Allee effect, that is decreased fitness at lower population densities, has been recognized as potentially playing an important role in the conservation of endangered species, in the practice of biological control, and the eradication of invasive species. Although a nu...

Distribution of the invasive ambrosia beetle Anisandrus maiche (Coleoptera, Sco...

Ambrosia beetles are highly successful as invaders because they are often transported internationally with wood packaging and other wood products and because their inbreeding mating systems facilitates establishment of invading populations. In 2022, two independent insect surveys in canton Ticino (southern Switzerland) revealed the widespread occurrence of the invasive ambrosia beetle Anisandrus maiche (Kurentz...

Decomposing drivers in avian insectivory: Large-scale effects of climate, habit...

Aim: Climate is a major driver of large-scale variability in biodiversity, as a likely re- sult of more intense biotic interactions under warmer conditions. This idea fuelled decades of research on plant-herbivore interactions, but much less is known about higher-level trophic interactions. We addressed this research gap by characterizing both bird diversity and avian predation along a climatic gradient at the ...

Another chapter in the history of the European invasion by the Western conifer ...

The Western conifer seed bug, Leptoglossus occidentalis, is native to North America and has already been considered a significant pest in several European countries since its first observation in Italy in 1999. In Spain and Portugal, it was recorded for the first time in 2003 and 2010, respectively, and its impact on Stone Pine (Pinus pinea) is of major concern. Before developing control measures for this insec...

Eradication programs against non-native pests and pathogens of woody plants in ...

When a non-native species succeeds in establishing in a new habitat, one of the possible responses is to attempt its eradication. In the present study, we analysed European eradication programmes against non- native pests and pathogens of woody plants (PPWP) from 1945 to date. Our main goal was to identify which factors affect the success of an eradication programme, reinforcing guidelines for future eradica- t...
