Abstract
The efficacy of two plant (ethanol&hexan) extracts namely:Geranium, Geranium macrorrhizum Album and Oleander, Nerium oleander L. 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.
On the other hand , the same trend occurred with ethanol-oleander against eggs but differ with hexane-geranium , extrac produced higher activity than ethanol extract.
