Pesticidal compositions for the control of dust mites containing one or more plant essential oils. In addition, the present invention is directed to a method for controlling dust mites by applying a pesticidally-effective amount of the above pesticidal compositions to a locus where pest control is desired.

The invention provides a method for producing a modified major mite allergen, obtained by altering a major allergen of house dust mites by gene engineering, which involve the steps of culturing prokaryotic or eukaryotic host cells transformed with a replication vector containing a gene encoding modified major mite allergen expressed from a promoter and collecting the expressed modified major mite allergen from the culture. The present invention provides a modified major mite allergen produced by the method, DNA molecules encoding same, and a pharmaceutical composition containing the modified major mite allergen.

The present invention provides isolated peptides of the major protein allergens of the genus Dermatophagoides. Peptides within the scope of the invention comprises at least one T cell epitope, or preferably at least two T cell epitopes of a protein allergen selected from the allergens Der p I, Der p II, Der f I, or Der f II. The invention also pertains to modified peptides having similar or enhanced therapeutic properties as the corresponding, naturally-occurring allergen or portion thereof, but having reduced side effects. The invention further provides nucleic acid sequences coding for peptides of the invention. Methods of treatment or of diagnosis of sensitivity to house dust mites in an individual and therapeutic compositions comprising one or more peptides of the invention are also provided.

The invention discloses a preparation method of composite long-acting antibacterial and anti-mite down fibers. The preparation method comprises the following steps of: (1) selecting down raw materials; (2) pre-treating, namely removing stems of the raw materials, removing sand dust, finely classifying, carrying out primary washing, washing and dehydrating; (3) immersing the down raw materials, which are cleanly washed, into a water solution containing 0.6% (o.w.f) of a Sanitized antibacterial and anti-mite auxiliary agent AM98-12N, 1% (o.w.f) of modified chitosan, 2% (o.w.f) of an Archroma chemical binding agent Appretan N 96101 at 40-50 DEG C for 30min; and (4) dehydrating, pre-drying, baking and cooling the immersed downs. The down fibers prepared by the method provided by the invention has an obvious antibacterial and anti-mite effect; the bacteria inhibition rates on candida albicans, escherichia coli and staphylococcus aureus reach more than 99%, and the repelling ratio of house dust mites reaches more than 95%; the composite long-acting antibacterial and anti-mite down fibers have the long-acting property and have a protection effect on daily health of people, and the living quality of people is greatly improved.

The present invention relates to a natural acaricide having acaricidal activity against mites and an identification marker. More specifically, the present invention relates to a natural acaricide, an identification marker having an effect of identifying mites, and a method for manufacturing the same, the natural acaricide having excellent acaricidal activity effect against mites such as house dust mites and Haemaphysalis longicornis (murder mites) while using materials obtained by fractionizing and purifying essential oil of Melissa officinalis (lemon balm) or Morindae officinalis Radix extracts, which are natural ingredients, not synthetic materials.

Polymeric articles such as fibres and foams having incorporated therein a chemical compound which has antifungal activity against fungi of the groups Aspergillus glaucus and / or A. restrictus are useful in controlling house dust mites and bedmites Dermatophagoides spp.
