- Editorial: Ladybirds: Conservation, ecology and interactions with other organismsPublication . Haelewaters, Danny; Losey, John E.; Soares, António O.Human impact on the natural world has expanded enormously over the past century and a half, with rapid population growth and an increasingly globalized economy causing pollution, habitat destruction, and climate change (Johnson et al., 2017). This threatens biodiversity and proper functioning of natural ecosystems, which we depend on for resources (wood, food, etc.) and ecological services (water storage and purification, waste treatment, pollination, etc.) (Vilà et al., 2006; Newbold et al., 2015; Dasgupta, 2021).

G.; Zhu, Zeng-Rong; de Kroon, HansA growing number of studies are providing evidence that a suite of anthropogenic stressors — habitat loss and fragmentation, pollution, invasive species, climate change and overharvesting — are seriously reducing insect and other invertebrate abundance, diversity and biomass across the biosphere. These declines affect all functional groups: herbivores, detritivores, parasitoids, predators and pollinators. Insects are vitally important in a wide range of ecosystem services of which some are vitally important for food production and security (for example, pollination and pest control). […].
- A roadmap for ladybird conservation and recoveryPublication . Soares, António O.; Haelewaters, Danny; Ameixa, Olga M. C. C.; Borges, Isabel; Brown, Peter M. J.; Cardoso, Pedro; de Groot, Michiel D.; Evans, Edward W.; Grez, Audrey A.; Hochkirch, Axel; Holecová, Milada; Honěk, Alois; Kulfan, Ján; Lillebø, Ana I.; Martinková, Zdenka; Michaud, J.

The richness, abundance, and distribution of ladybirds, however, are compromised by many anthropogenic threats. Meanwhile, a lack of knowledge of the conservation status of most species and the factors driving their population dynamics hinders the development and implementation of conservation strategies for ladybirds. We conducted a review of the literature on the ecology, diversity, and conservation of ladybirds to identify their key ecological threats. Ladybird populations are most affected by climate factors, landscape composition, and biological invasions. We suggest mitigating actions for ladybird conservation and recovery. Short-term actions include citizen science programs and education, protective measures for habitat recovery and threatened species, prevention of the introduction of non-native species, and the maintenance and restoration of natural areas and landscape heterogeneity. Mid-term actions involve the analysis of data from monitoring programs and insect collections to disentangle the effect of different threats to ladybird populations, understand habitat use by taxa on which there is limited knowledge, and quantify temporal trends of abundance, diversity, and biomass along a management-intensity gradient. Long-term actions include the development of a worldwide monitoring program based on standardized sampling to fill data gaps, increase explanatory power, streamline analyses, and facilitate global collaborations.
