## Abstract In this study we assess the effect of pyrrolizidine alkaloids (PAs) extracted from __Lithospermum canescens__ on the biology of the two‐spotted spider mite (__Tetranychus urticae Koch__). __Lithospermum canenscens__ (Michaux) Lehm. (__Boraginaceae__) is a common prairie plant also known
