Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Biology of the Gall Midge Spanolepis selloanae (Diptera, Cecidomyiidae), a Candidate Biological Control Agent of the Invasive Grass Cortaderia selloana

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Spanolepis selloanae (Diptera, Cecidomyiidae) infests Cortaderia selloana (pampas grass). It lays eggs in the spikelets, where larvae feed on female parts. The high prevalence of the midge and its combined impact in seed production, condition and viability strongly reduces the reproductive output of C. selloana.

Soil inoculation enhances early‐phase reintroduction success in two rare plant species

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Reintroduction for conservation is an important measure to restore populations of vulnerable plant species. However, reintroduction success rates are relatively low. Inoculating reintroduced plants with facilitative microorganisms from native populations may enhance their performance.
