“…Critically, these conclusions come from robust datasets (Kunin, 2019), spanning decades of monitoring effort (Hallmann et al, 2020; Macgregor et al, 2019; Roth et al, 2020; Skarbek et al, 2021), and global assessments of taxa‐specific datasets (Balfour et al, 2018; Hallmann et al, 2017; Zattara & Aizen, 2021). As Forister et al (2019) succinctly put it: we know enough about insect declines to act now.…”

The Millennium Ecosystem Assessment assessed ecosystem change, human wellbeing and scientific evidence for sustainable use of biological systems. Despite intergovernmental acknowledgement of the problem, global ecological decline has continued, including declines in insect biodiversity, which has received much media attention in recent years. Several roadmaps to averting biological declines have failed due to various economic and political factors, and so biodiversity loss continues, driven by several interacting human pressures. Humans are innately linked with nature but tend to take it for granted. The benefits we gain from the insect world are broad, yet aversion or phobias of invertebrates are common, and stand firmly in the path of their successful conservation. Providing an integrated synthesis for policy teams, conservation NGOs, academic researchers and those interested in public engagement, this article considers: (1) The lack of progress to preserve and protect insects. (2) Examples relating to insect decline and contributions insects make to people worldwide, and consequently what we stand to lose. (3) How to engage the public, governmental organizations and researchers through “insect contributions to people” to better address insect declines. International political will has consistently acknowledged the existence of biodiversity decline, but apart from a few narrow cases of charismatic megafauna, little meaningful change has been achieved. Public values are reflected in political willpower, the progress being made across the world, changing views on insects in the public should initiate a much‐needed political sea‐change. Taking both existing activity and required future actions, we outline an entomologist's “battle plan” to enormously expand our efforts and become the champions of insect conservation that the natural world needs.

“…Furthermore, attention was paid to the family of Carabidae, since a decline in species diversity has been observed in Germany in recent decades within this family. Only 43% of native Carabidae species are currently considered to be nonthreatened (Drees et al, 2019; Homburg et al, 2019; Schmidt et al, 2016; Skarbek et al, 2021). Accordingly, avoiding bycatch is a high priority for the development of mass trapping methods for H. abietis that involve the large‐scale use of pitfall traps.…”

Different trap types and attractant compositions were tested with the goal of attracting as many individuals of Hylobius abietis as possible while assuring a minimal bycatch of nontarget species with regard to the family Carabidae on three study sites in the east of Germany. The results revealed a modified pitfall trap based on a model by Nordlander (1987, Scandinavian Journal of Forest Research, 2, 199–213.) as the most effective trap type with a high degree of selectivity and minimal ecological side effects. The modified Nordlander trap is suitable for potential H. abietis mass trapping as an instrument of integrated pest management. Two field trials testing different attractant compositions showed that a simple attractant combination of (−)‐α‐pinene and ethanol is as effective as other more complex combinations and thus preferable for mass trapping efforts. The addition of the monoterpenes camphene, Δ‐3‐carene, ocimene and terpinolene to the combination of (−)‐α‐pinene and ethanol did not increase trapping numbers significantly. Trapping numbers of H. abietis indicate that a reduction of the local H. abietis population by trapping is possible, though further research about the influence of mass trapping on regeneration damage is recommended.

“…Mean temperature is the most influential factor in previous summer while rainfall is the most influencing factor during previous autumn, and winter. Rainfall has already been identified as a driver of carabid distribution via change of species composition, not activity density or richness (Skarbek et al, 2021). In this line, evidence shows that soil moisture in winter benefits carabid emergence (Holland et al, 2007), females carabids could prefer oviposition sites with adapted moisture conditions.…”

Understanding effects on the huge diversity of cropping systems on local biodiversity is challenging but necessary to implement agroecological systems. Through a functional approach, the translation of cropping systems into resource and disturbance gradients is promising to decipher the relationship between cropping systems and biodiversity but has never been implemented for arthropods. To investigate contributions of resource and disturbance gradients arising from cropping systems vs environmental context (regional effect, meteorological conditions and landscape characteristics) on beneficial arthropod communities, we used a dataset collected in 60 crop fields from three French areas over a five-years period. It includes all farmers interventions, crop sequences, meteorological data, landscape composition and carabid samplings. We found that the environmental context contributed to about 75% of explained carabid variations on average, while resource and disturbance gradients contributed to about 25% of explained carabid variations. The resource and disturbance gradients were particularly important in winter and spring preceding the spring-summer period to determine carabid variations. Moreover, we identified thresholds above which resource and disturbance gradients start being beneficial or detrimental for carabids. For example, a Treatment Frequency Index above 2.07 in spring decreased the total activity density of carabids during the spring-summer period. Synthesis and application. While implementing for the first time a functional approach to understand the effects of different facets of cropping systems on arthropods, our study also allows us to identify periods and thresholds above which specific practices affect carabids. The identification of such thresholds can guide the provision of recommendations for policy, stakeholders and farmers about how to reduce cropping systems' impact on arthropods.
