New Position Statement: In Defense of Insect Biodiversity

Biodiversity is the single most valuable resource on Earth

Annapolis, MD; October 24, 2017—More than half of all species on Earth are insects and related arthropods, and they play vital roles in nearly every ecosystem: as pollinators, decomposers, predators, natural enemies against invasive species and pests, sources for new genetic and medical breakthroughs, and food for other organisms.

However, significant challenges to preserving planetary biodiversity are presented by human activity, ranging from habitat loss to climate change to the spread of invasive species. The Entomological Society of America advocates for the protection and exploration of Earth's largest and most diverse lineage of living organisms in its new position statement on arthropod biodiversity.

Earth's Inhabitants

Biodiversity is the single most valuable resource available to Earth's human inhabitants. Insect species and populations are often valuable indicators of ecosystem health and stability, and monitoring key insect groups can assist with early detection of potential ecological shifts that might adversely affect human welfare.

ESA urges the American public and policymakers to support the protection and exploration of Earth's biodiversity, particularly with regard to insects and other related arthropods, and for the appropriate funding and policies to do so, specifically in the following areas:

  • Continued study of insects and their relatives, together with all aspects of their biology and potential values to humanity.
  • Habitat protection, with an emphasis on native species.
  • Increased discovery and exploration of biodiversity within our country and our world.
  • Enhanced domestic and international collaboration between entomologists, other scientists, lawyers, policymakers, and citizens to prevent the loss of native species.
  • Improved management techniques and best practices, utilizing effective science-based management of specific highly injurious pest and vector species.
