Are Botanical Biopesticides Safe for Bees (Hymenoptera, Apoidea)?

open access: yesInsects, 2023
The recent global decline in insect populations is of particular concern for pollinators. Wild and managed bees (Hymenoptera, Apoidea) are of primary environmental and economic importance because of their role in pollinating cultivated and wild plants, and synthetic pesticides are among the major factors contributing to their decline.

Pollen exploitation by non‐native, feral honey bees: Potential consequences for interspecific competition

open access: yesInsect Conservation and Diversity, EarlyView.
In Southern California, a global hotspot of bee biodiversity, predominantly feral populations of the exotic western honey bee constitute an estimated 90% of individual bees and 98% of bee biomass. Honey bee foragers remove 80% of total pollen during the first day flowers open on three common native species, with their first two visits removing over 60%

Spatial Interpolation in Applied Insect Ecology: A Review, Including Guidelines and Datasets for Practical Use

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Spatial interpolation represents a fundamental approach in applied insect ecology, offering insight into species distributions and supporting biodiversity analysis, pest management and disease vector mapping. Insects—including important pollinators—face escalating threats due to habitat loss, climate change and anthropogenic pressures. As data‐

The Buzz of Inconsistency: Pollinator Potential vs. Research Effort

open access: yesJournal of Applied Entomology, Volume 149, Issue 7, Page 1050-1058, August 2025.
ABSTRACT Pollinator insects are essential for the functioning of terrestrial ecosystems and play a critical role in ensuring food security; thus, studies on this topic provide significant benefits for human society. Pollination involves diverse taxa that can vary depending on the specific environment.

A catalogue of the Ampulicidae (Hymenoptera, Apoidea) of Eritrea

open access: yes, 2023
Currently, the family Ampulicidae is represented by only two species of the genus Ampulex JURINE, 1807 (subfamily Ampulicinae) in Eritrea: A. brunneofasciata GIORDANI SOIKA, 1939 and A. conigera KOHL, 1893. The type of the latter is missing in the collection of the Natural History Museum Vienna (Austria).

Biodiversity response to local‐scale conservation interventions: A systematic review and meta‐analysis protocol

open access: yesEcological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.
Local‐scale conservation interventions aim to mitigate biodiversity loss, but we lack consensus about their effectiveness. We present a protocol to systematically review the evidence and use meta‐analysis to assess these interventions' overall impact on biodiversity.
