De­cline of wild bees threat­ens US crops’ pol­li­na­tion

Asian Journal - - WORLD -

Wash­ing­ton: The de­cline in the pop­u­la­tion of wild bees threat­ens agri­cul­ture in the US, where 39 per­cent of crops de­pen­dent on such pol­li­na­tors may not re­ceive the in­sects this year, a study says. Some 39 per­cent of pol­li­na­tor-de­pen­dent crops “ex­hibit a mis­match be­tween pol­li­na­tion sup­ply and de­mand, with large ar­eas of pol­li­na­tor-de­pen­dent crops and low ex­pected abun­dance of wild bees,” Univer­sity of Ver­mont re­searchers found. Wild bees are dis­ap­pear­ing from a num­ber of re­gions, in­clud­ing agri­cul­tural ar­eas in Cal­i­for­nia, such as the Cen­tral Val­ley, the up­per Mid­west and the Corn belt in the Great Plains, as well as the southern Mis­sis­sippi River Val­ley.
