“…The compound also functions as the alarm pheromone of Tyrophagus perniciosus (Leal et al, 1988), and has been detected as a major or minor component with unknown functions from Dermatophagoides farinae (Kuwahara et al, 1990), Ac. siro (Curtis et al, 1981), T. putrescentiae (Leal et al, 1988) and S. rodriguezi (Ayorinde et al, 1984;Mori et al, 1995).…”

2-Hydroxy-6-methylbenzaldehyde (2,6-HMB) was identified as the female sex pheromone from the acarid mite, Cosmoglyphus hughesi. Although the sex pheromone functioned to stimulate males to tap females and then mount, it was detectable as a major component of hexane extracts not only from females but also from males and protonymphs. Its contents were estimated to be 283.1Ϯ49.4 ng per female, 135.2Ϯ25.5 ng per male and 3.8Ϯ0.4 ng per protonymph. Sexual activity was induced in males by exposure of a filter paper impregnated with 100 ng of synthetic 2,6-HMB. Behavioral observation demonstrated that the male could not distinguish females from males upon attempt to mate.

“…As for the house-dust mites, fungistatic substances like citral and neryl formate have been discovered in T. putrescentiae, while A. siro secreted 2-hydroxy-6-methyl benzaldehyde, a substance suspected to have an antifungal effect. However, some chemicals without any known effect are found in their exudate [55].…”

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.

“…With the lack of other evidence to the contrary, and regardless of its volatile nature, it may play a role as a waterproofing agent. This is further supported by the fact that the pheromone 2‐hydroxy‐6‐methylbenzaldehyde,16, 20 which was present in greater quantities in the mites, was only absorbed at 1.5–10% as much as tridecane. If tridecane does have this role, then it could be concluded that DE has a similar mode of action against mites as hypothesised for insects.…”

Encapsulation of aluminum flakes by dispersion polymerization of styrene in a nonaqueous system with reactive surfactants

Dispersion polymerization of styrene in ethanol was carried out to encapsulate aluminum flakes. The effects of three reactive surfactants, two anionic and one nonionic, were investigated. It was confirmed prior to encapsulation that these surfactants did not polymerize by themselves but did promote polymerization of styrene. The capsules obtained were characterized with respect to the morphology and mean size. The encapsulating efficiency of the polymer of the wall material, the wall thickness, and the molecular weight distribution were measured. The effects of the concentrations of styrene monomer and reactive surfactants on these characteristics were determined and discussed. Aluminum flakes were coagulated to form secondary particles and they were covered with fine polymer particles, which were precipitated in the continuous phase. To improve encapsulation, the auxiliary addition of nonionic surfactant was attempted. By controlling those concentrations, capsules covered with polymer layer were prepared.
