House Dust Sensitivity and Environmental Control

Acaricidal Activity of Clove Bud Oil Compounds againstDermatophagoides farinaeandDermatophagoides pteronyssinus(Acari: Pyroglyphidae)

“…The structure of the active isolate was determined by spectroscopic analyses. 1 H and 13 C NMR spectra were recorded in deuteriochloroform with a Bruker AM-500 spectrometer at 400 and 100 MHz, respectively. UV spectra were obtained in methanol with a Jasco V-550 spectrophotometer and mass spectra on a JEOL GSX 400 spectrometer.…”

“…The most important pyroglyphid mites are the American house dust mite, Dermatophagoides farinae (Hughes), and the European house dust mite, Dermatophagoides pteronyssinus (Trouessart), because of their cosmopolitan occurrence and abundance in homes (1,2), because they are a major source of multiple potent allergens (3,4), and because of their causal association with sudden infant death syndrome (5). Changes in living environments such as a rise in the number of apartment households with centrally installed heating, space heating, tighter windows, and fitted carpets have improved conditions for mite growth (1). Control of these mite populations has been principally through the use of chemicals such as γ-benzene hexachloride (γ-BHC), pirimiphos-methyl, benzyl benzoate, N,N-diethyl-m-toluamide (DEET), and dibutyl phthalate (1).…”

Although effective, their repeated use has sometimes resulted in the development of resistance (3), has undesirable effects on nontarget organisms, and has fostered environmental and human health concerns (1,6).…”

Although effective, their repeated use has sometimes resulted in the development of resistance (3), has undesirable effects on nontarget organisms, and has fostered environmental and human health concerns (1,6). These problems have highlighted the need for the development of new strategies for selective house dust mite control.…”
