Insects are little different from other biological organisms, they
need three primary things - food, shelter, security.
 
Man in his wisdom (??) turns to monoculture, removes hedges and
ploughs then sprays insecticides everywhere.  If you can control this
you will get increased numbers of bumble bees and other solitary
bees.
 
Nature does not like a vaccum but will not invade areas where its
chances of survival are low.
