Development data available for the black soldier ßy are limited to studies using an artiÞcial diet (Furman et al. 1959, May 1961, Tomberlin et al. 2002). Consequently, predicting the black soldier ßy life cycle under Þeld conditions in conÞned animal facilities is based on extrapolations from these previous studies.The primary objective of this study was to examine the life history traits of black soldier ßies fed four different feed rates of dairy manure, a previously unexamined
dietary medium. Additionally, reduction of dry matter and associated nutrients in dairy manure by black
soldier ßy larvae was examined.
