A small population of the sunflower leafcutting bee,Eumegachile (Sayapis) pugnata(Say), was managed to determine its efficacy as a sunflower pollinator and to evaluate its potential as a “domesticated” pollinator. Artificial wooden nesting sites were made available for the population obtained from adjacent forest and range lands the previous year. After release, both females and males visited and effectively pollinated most hybrid cultivars tested. Characteristics that were found favorable to its management were: bees would nest gregariously; overwintering populations could be stored, incubated, and released in synchrony with sunflower bloom; bees could be obtained by trapping wild populations; and populations could be transported from field to field during the nest provisioning stage. Immature mortality factors were analyzed, and potential predators, parasites, and diseases were identified.
