Were assayed against the bulb mite Rhizoglyphus echinopus (F.&R.). Obtained results showed that ethanol oleander extract exhibited the highest toxic action against adult females for both disk of yeast and dipping techniques, followed by hexane- geranium , hexane-oleander and ethanol-geranium extracts , where as values of LC₅₀ were :26.958 ,35.059 ,52.212 and 54.989 respectively.
