Studies on the bionomy of two species of stored product mites Tyrophagus putrescentiae Schrank and Rhizoglyphus echinopus (F. & R.) were carried out on a diet with ethanol extracts of medicinal and spicy plants: Azadirachta indica A. Juss., Artemisia dracunculus L., and Piper retrofractum (Vahl). Complete development of the mites was observed. In comparison with clean wheat germs the development of the studied mite colonies was, however, slower on food with the extracts. Extracts of Azadirachta indica, commonly applied as toxic antifeedants and deterrents to many orders and species of insects were found to be less effective to acarid mite control. The results of the experiment showed that acarid mites are more resistant to the effect of these plant compounds than insects.
