The dual crisis: Climate change simultaneously drives pollinator decline and pest outbreaks

Agricultural and Forest Entomology, EarlyView.
Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive

Managed honey bees as a radar for wild bee decline? [PDF]

Apidologie, 2020
Wild and managed bees are essential for global food security and the maintenance of biodiversity. At present, the conservation of wild bees is hampered by a huge shortfall in knowledge about the trends and status of individual species mainly due to their

Impact of managed honey bee viruses on wild bees

Current Opinion in Virology, 2016
Several viruses found in the Western honey bee (Apis mellifera) have recently been detected in other bee species, raising the possibility of spill-over from managed to wild bee species. Alternatively, these viruses may be shared generalists across flower-visiting insects.

Wild Bees and their Conservation

Indian Journal of Entomology, 2021
About sustainable agricultural environment and world food security, major crops mainly dependent upon managed honey bees and wild bee pollinators which are of great significance. Bee pollinated crops being a great part of the bio-diverse system, 4,000 native bees, and offer over US$1.5 billion each year in North America.

The conservation and restoration of wild bees

Annals of the New York Academy of Sciences, 2010
Bees pollinate most of the world's wild plant species and provide economically valuable pollination services to crops; yet knowledge of bee conservation biology lags far behind other taxa such as vertebrates and plants. There are few long‐term data on bee populations, which makes their conservation status difficult to assess.
