Acaricidal activity of cinnamaldehyde and its congeners against Tyrophagus putrescentiae (Acari: Acaridae)

The acaricidal activity of cinnamaldehyde and its 11 congeners against adults of Tyrophagus putrescentiae was examined using direct contact application and fumigation methods and compared with that of benzyl benzoate, N, N-diethyl- m-toluamide (DEET) and dibutyl phthalate. On the basis of 24 h LD 50...

Description
Summary:The acaricidal activity of cinnamaldehyde and its 11 congeners against adults of Tyrophagus putrescentiae was examined using direct contact application and fumigation methods and compared with that of benzyl benzoate, N, N-diethyl- m-toluamide (DEET) and dibutyl phthalate. On the basis of 24 h LD 50 values, the compound most toxic to T. putrescentiae was cinnamyl acetate (0.89 μg/cm 2) followed by cinnamaldehyde (1.12 μg/cm 2), benzaldehyde (1.93 μg/cm 2), 3-phenylpropionaldehyde (2.08 μg/cm 2), cinnamyl alcohol (2.12 μg/cm 2), salicylaldehyde (2.75 μg/cm 2), and ( E)-2-hydroxycinnamic acid (4.32 μg/cm 2). These compounds were more potent than benzyl benzoate (10.03 μg/cm 2), DEET (13.39 μg/cm 2) and dibutyl phthalate (12.87 μg/cm 2). Very low activity (
