Food protective and color alteration effects of acaricidal aldehydes on Tyrophagus putrescentiae (Schrank)

The activities of benzaldehyde isolated from Prunus persica seeds and of commercially available aldehydes against Tyrophagus putrescentiae (a stored-food mite) adults were examined and compared with those of the synthetic acaricides benzyl benzoate and N,N-diethyl-m-toluamide. On the basis of the 50...

Description
Summary:The activities of benzaldehyde isolated from Prunus persica seeds and of commercially available aldehydes against Tyrophagus putrescentiae (a stored-food mite) adults were examined and compared with those of the synthetic acaricides benzyl benzoate and N,N-diethyl-m-toluamide. On the basis of the 50% lethal dose (LD50), the compound most toxic to T. putrescentiae adults was salicylaldehyde (LD50 of 1.02 microg/cm2) followed by cinnamaldehyde (1.66 microg/cm2), benzaldehyde (4.23 microg/cm2), phthaldialdehyde (5.16 microg/cm2), benzyl benzoate (9.75 microg/cm2), and N,N-diethyl-m-toluamide (16.26 micorg/cm2). Benzaldehyde was about 2.3 and 3.8 times more toxic than benzyl benzoate and N,N-diethyl-m-toluamide, respectively, against T. putrescentiae adults. These results indicated that benzaldehyde isolated from P. persica seeds and the three aldehydes (cinnamaldehyde, salicylaldehyde, and phthaldialdehyde) are useful as lead compounds for developing acaricidal agents against T. putrescentiae adults. The color of the T. putrescentiae cuticle was changed by treatment with cinnamaldehyde, salicylaldehyde, and phthaldialdehyde.
