Acaricidal properties of piperazine and its derivatives against house-dust and stored-food mites.

The article presents a study which examines the acaricidal properties of piperazine derivatives against Dermatophagoides farinae or house-dust mites and Tyrophagus putrescentiae or stored-food mites using filter paper and fumigant methods. It notes that 1-phenylpiperazine was found to be 4.7 times more toxic than N,N0-diethyl-meta-toouamide (DEET) against Dermatophagoides farinae. Further, it stresses the suitability of piperazine derivatives to replace ineffective acaricides due to their ability to function as mite indicators.
