“…The stock jars of each species were closed by double layers of muslin and kept in an electrical incubator at 25±2°C and 80±5% RH. After six months, large numbers of different stages were available for toxicological experimentation (Georges-Gridelet, 1987;Andersen, 1988;Rezk and Gadelhak, 2003).…”

A B S T R A C TThe present study was conducted at Elkom Elakhdar village, Shebin El-Kom, Menoufia Governorate along 2012 year seasons, to calculate and identify the species composition and the occurrence frequency of the extracted dust mites collected from three building ages at rural houses, as well as to determine the toxicity limits of different concentrations of three plant essential oils against two species of the family Pyroglyphidae the main causal of allergy to humans. The obtained results revealed that there were eleven mite species belong to five families (Pyroglyphidae, Chortoglyphidae, Glycyphagidae, Acaridae and Cheyletidae). Of the total collected mites (5276) the highest dominant percentage species was the dust mites: Dermatophagoides farinae (66.1%), followed by D. pteronyssinus (23.3%), while the percentages of the rest species: Chortoglyphus arcuatus, Lepidoglyphus destructor, Glycyphagus domesticus, Gohieria fusca, Tyrophagus putrescentiae, Caloglyphus sp, Cheyletus malaccensis, Blomia sp. and Acarus siro were ranged between 0.16-2.0%. Regarding to the effect of temperature degrees on mite population, high degrees more than 25°C at summer season, decreased the numbers of D. farinae and D. pteronyssinus. Toxicological tests of the three plant essential oils against adult stages of D. farinae and D. pteronyssinus showed that lemon grass oil gave the highest toxicity effect, in comparison with geranium and thyme oils, where mortality percentages were approximately around 100% at 800 ppm concentration on both species. The LC 50 of lemon grass were 228.992 and 293.615 ppm against the two species, respectively. From the results of the research, it could be recommend that it is preferable to apply control operation during summer season where the mite population density is the least, moreover, the botanical oil extracts effectively controlled the parasitic dust mites, D. farinae and D. pteronyssinus and can be used in the biological control programs, as well as, it can play effective role in the integrated management programs.

“…This is not only the case for D. pteronyssinus in culture but also for stored-food mites [28]. This observation could be explained by the occurrence of toxic substances in the fungal diet [21,28,29] and/or by the fact that dense fungal colonisation of the substratum mechanically inhibits the movement of mites [21,30]. Note that the latter explanation for a negative impact of fungus is related to the physical structure of the culture medium.…”

“…Van Bronswijk and Sinha [22] proposed that the fungus A. amstelodami predigests human dander (predigestion of the lipid content of the skin scales to assimilate fatty acids) and could also be involved in the production or release of sterols. de Saint Georges-Gridelet [23] suggested that A. penicilloides contributes to the B and D vitamin requirement of D. pteronyssinus. However, with regard to the contribution of fungi to the modification of dietary components for mites, Douglas and Hart [24] concluded that no experimental studies provided unambiguous evidence for this.…”

In the indoor environment, mites and fungi are two of the most important causes of asthma and rhinitis in people. Although these two subjects are often studied separately, to do so ignores the important ecological relationship between them. For example, fungi may be a source of nutrients, providing the sterols and vitamins required by one of the most important house-dust mites, Dermatophagoides pteronyssinus. In addition, two other mite species also found in the indoor environment, Acarus siro and Tyrophagus putrescentiae, are attracted by fungi and feed on some species of them. In return, these two mite species are capable of inoculating the micro-organisms into clean food commodities. This review is an attempt to highlight the complex interaction between mites and fungi and to give an overview of our knowledge of this microscopic world. It also hopes to give a clearer understanding of the mechanisms by which fungicides can control, or not, the development of domestic mite populations.

“…The house dust mite, D. pteronyssinus, was isolated from mattress dust and reared on a finely-ground mixture of dust, dried yeast and dried milk (1:1:0.5) in complete darkness (de Saint Georges-Gridelet, 1987). Stock jars were kept in an incubator at an average temperature of (25±2) °C and relative humidity of (80±5)%.…”

Abstract:The acaricidal activities of fourteen essential oils and fourteen of their major monoterpenoids were tested against house dust mites Dermatophagoides pteronyssinus. Five concentrations were used over two different time intervals 24 and 48 h under laboratory conditions. In general, it was noticed that the acaricidal effect based on LC 50 of either essential oils or monoterpenoids against the mite was time dependant. The LC 50 values were decreased by increasing of exposure time. Clove, matrecary, chenopodium, rosemary, eucalyptus and caraway oils were shown to have high activity. As for the monoterpenoids, cinnamaldehyde and chlorothymol were found to be the most effective followed by citronellol. This study suggests the use of the essential oils and their major constituents as ecofriendly biodegradable agents for the control of house dust mite, D. pteronyssinus.
