Despite the UK being a leader in this field of research, there remains a scarcity of comprehensive and comparable data which poses a significant challenge in accurately assessing the extent and underlying causes of insect decline.

The lack of long-term monitoring programmes for many insect species, and inconsistent data collection methods, hampers the ability to discern trends over time.

The Government and its agencies like UKRI should produce a clear strategy for sustaining long-term insect monitoring research. This involves not only maintaining existing projects but also initiating new studies that can address insect data gaps.

This involves not only maintaining existing projects but also initiating new studies that can address insect data gaps. Funders should commit to the longer term funding which is needed for insect monitoring projects, extending beyond the usual five-year cycle of research grants and ensure that these studies have clear channels for the incorporation of data collected by amateur groups.

A fatalistic approach risks reducing the chances of changes being made to policy, behaviour and practices that can make a real difference to stopping and reversing insect decline. Empowering both the public and policy makers is a more effective tool for change than implying hopelessness. Show less

The Government and its agencies should consider ways in which to communicate not only the reality of insect decline but also the attainable steps that can be taken to tackle it. (Paragraph 42) The importance of insects for UK Food Security

There is scope to build on the work of the strategy by creating a complementary ‘National Invertebrate Strategy’ that would include provisions for invertebrates that carry out other important ecological roles. As seen in the creation of the National Pollinator Strategy, the National Invertebrate Strategy should include the publication of an implementation plan, containing accountability targets, linked to the strategy every five years for non-pollinating, agriculturally beneficial, invertebrates.

These imported foods may be subject to vulnerabilities, such as wars, which can see significant price increases. Approximately 50% of the food consumed in the UK comes from overseas. Therefore, it is integral to UK food security that the issues regarding insect decline and food production are also addressed at an international level. The UK Government should use its position in international forums to advocate for and address the issues highlighted in this report on a global scale. Collaborative efforts are essential to mitigate the challenges posed by insect decline and to secure sustainable and resilient food systems worldwide. Show less

The concentrations of … Read more Charismatic insect species, of which the honeybee is a prime example, serve as invaluable ambassadors for the field of entomology, rendering the subject more accessible to the public and bringing to public attention this often-overlooked animal group. The concentrations of high numbers of hives in a small number of specific geographical areas may have detrimental effects on wild pollinator species due to resource competition. Consequently, there is a need to extend the range of conservation efforts to include the over 270 wild species of bees in the UK, acknowledging the importance of preserving the entire spectrum of biodiversity for a more balanced and resilient ecosystem.

While the collection of insect monitoring data remains invaluable for entomology, citizen science projects serve a broader purpose. We agree with the perspective of conservation experts, acknowledging that participation in such projects not only aids insect research but also enriches the lives of participants by fostering a deeper connection with the natural world. Citizen science projects allow researchers access to insect data from broad geographic areas that they may not have the resources to sample themselves. However, this type of survey must supplement, not replace, expert-led academic research projects. Show less

ELMS should also show that it delivers better environmental outcomes than previous agri-environmental schemes. However generous and efficient the payment system is, the actions being rewarded need to have their impacts monitored and assessed to ensure specific outcomes like improved insect populations are delivered by ELMS and that public money is well spent. Successful execution of this monitoring, coupled with feedback from farmers and land managers, will give a more comprehensive overview of the individual and collective effects of ELMS implementation.

To enhance the successful implementation of IPM, it is imperative to adopt innovative approaches and new tools, such as integrating resistant plant varieties, the use of biopesticides or new pheromones, artificial intelligence decision support systems, and advances in agronomy as and when they are developed. For widespread adoption within the farming community, effective and sustainable crop protection strategies should be demonstrated at a commercial scale. Show less

However, the exclusion of numerous invertebrate species and in some cases entire groups from the baseline metrics, particularly those vital for UK food security such as predatory beetles, is concerning. Including only 11 species of bumblebee is not an adequate abundance indicator for all 270 (at least) unique UK bee species. We are concerned that a significant number of insect or invertebrate species could go extinct or significantly decline in abundance, and yet the statutory targets could still be met by law.

In response to this report, the Government should set out what steps it is taking to gain approval from members of the Statutory Nature Conservation Bodies, so that data from species excluded from the 2022 Red List can be included in future iterations. Additionally, a detailed breakdown of how current data from the monitoring of excluded invertebrate species influence both the interim and final statutory biodiversity targets, should be published routinely. This should be in the form of an alternative ‘Baseline List’ to include species where the availability of data does not pass the threshold for inclusion in the ‘Red List’, but where evidence is available to determine a baseline conservation 50 Insect decline and UK food security status. This ‘Baseline List’ should include as many excluded insect species as possible, to act as baseline statistics from which all future interim and final progress reporting for the biodiversity targets will be made.

Protected sites do not exist in isolation and are therefore influenced by the quality of nature in the surrounding environment. Whilst we welcome the statutory improvements to SSSIs set out by the Environment Improvement Plan, which will go some way to prevent more insect species extinctions, our Inquiry heard it is unlikely that these improvements will be sufficient to halt decline in species abundance. This is particularly the case for more common species, where large numbers of individuals in a population are needed to play pivotal roles such as pollination effectively. Show less

This approach would aim to mitigate the dual risks of pest resistance development and adverse off-target effects on beneficial insects. Any alterations to the regulatory framework should include ongoing monitoring of the impact on non- target species in field environments, where approved active substances are employed. Moreover, there should be an expansion in the range of non-target species for which data is collected to assess a chemical’s impact prior to regulatory approval. The Government should outline in its response to this Report, how it intends to support the development, regulation and practical application of pesticide alternatives, including, but not exclusive, to biopesticides, hormones and mRNA technologies. The Government should set out how it intends to adapt the current regulatory systems to accommodate innovative pesticide alternatives so that regulatory approval for these technologies can, where possible, be expedited.
