Question #211937 on Yade changed:
https://answers.launchpad.net/yade/+question/211937

Jan Stránský proposed the following answer:
Hello,

to delete certain particle, use [1]

O.bodies.erase(bodyId)

if you have e.g. a list of bodies that you want to delete, you can use
something like this:

bodiesToBeDeleted = []
for b in O.bodies:
  if b.state.pos[0] > 10: # artificial condition for particles deletion,
use your own :-)
    bodiesToBeDeleted.append(b)
for b in bodiesToBeDeleted:
  O.bodies.erase(b.id)


good luck and if you have any more question, just ask :-)
Jan
