Claims

  1. Bomber fly (Heterostylum robustum) parasites typically destroy 20–40% of alkali bee larvae before overwintering; the handbook's most effective control is walking the beds between 9 am and noon for two to three weeks starting before bee emergence, to kill newly hatched flies that cannot yet fly.
