Pollinating insects are among the most crucial species groups on earth. Without them, much of the earth’s vegetation would not survive and the elaborate ecosystems they sustain would collapse. Today, pollinator declines have reached critical levels in most regions of the world. Threats to Pollinator Abundance and Diversity, the first book in the new series Pollinators in Peril, aims to cover the current knowledge and latest research on insect pollinators, the threats to their survival, declining populations, and what conservation actions ought to be taken. The book demonstrates most threats to pollinators are either directly or indirectly human-caused, such as chemicals, land alteration, and habitat loss due to agricultural practices, as well as climate change and its many ripple effects.

Covering everything from honeybee pathogens to butterfly range changes, this book covers concepts that are both crucial and topical for young researchers in entomology, upper-level students, and those working in adjacent fields. Governmental and non-governmental organizations will also benefit from this key resource.

• Compiles the most up-to-date knowledge on the threats to insect pollinators
• Covers a range of insect pollinator groups, including managed honeybees, native bees, butterflies, and hoverflies
• Contextualizes the causes of insect population declines within the bigger picture of climate change
