Abstract: A membrane enclosed fluid diffusion system for insect attractants and repellents, auto thermostatic heaters, and chemical delivery using an additive and/or selectively permeable membrane that interacts with the enclosed fluid to maintain steady delivery rates over a range of temperature and humidity. Systems can be formed with permeable membranes, impermeable membranes, chemical hydrates, wicks, scent fluids, fuel fluids, catalytic heaters, energy conversion devices, visible images, infrared images, trapping systems, sound systems, electronics, and apparel. The device results in efficient and effective devices for mosquito control drug delivery, and portable heaters.

Abstract: Compounds of formula (I) are described for deterring vermin, wherein R is unbranched or branched C1-C15 alkyl, which is unsubstituted or substituted by halogen, cyano or nitro; R1 and R2 are unbranched or branched C1-C12 alkyl, preferably C1-C6 alkyl, which is unsubstituted or substituted by halogen, cyano or nitro; and X and Y, independently of one another, are a straightchain or branched alkylene bridge with 1 to 20 carbon atoms, preferably an alkylene bridge with 1 to 3 carbon atoms, which is unsubstituted or substituted by halogen, cyano or nitro. Furthermore, an essentially non-therapeutical process for deterring vermin is described, which is based on the usage of these compounds, as well as verminrepellent compositions containing these compounds as the active ingredient, and finally the use of these compounds for producing vermin-deterring compositions and their usage in deterring vermin from animals, humans and objects. New compounds within the scope of formula (I) are also described.

Abstract: Use of agonists and antagonists of the nicotinergic acetylcholine receptors of insects for the non-systemic control of parasitic insects, such as fleas, lice and flies, on humans and on animals.

Abstract: Arthropod-controlling composition comprising an &agr;-pyrone compound shown by the formula: as an active ingredient provides an excellent activity for controlling arthropods, and therefore, the composition is utilized for controlling harmful arthropods.

Abstract: Pharmaceutical compositions for the topical treatment of androgen-related conditions, e.g., acne in humans containing an amount of the compound represented by formula II effective for the topical treatment of the androgen-related conditions, e.g., acne ##STR1## dissolved in an alcohol-water solvent system, such as ethanol-water ?97.6:2.4(w/w)! and having an apparent pH in the range of about 3.5 to 4.5, and containing a gelling agent are disclosed.

Abstract: The present invention provides a collar containing a novel gel formulation of a wax and linear aliphatic hydrocarbon combination capable of the controlled release of an insecticide such as chlorpyrifos for the control of arthropods infesting animals. FIG. 1 depicts release rate proportional to chlorpyrifos (DURSBAN) concentration.

Abstract: Compositions for treating animals and surfaces infested with ectoparasites are provided for. The compositions comprise providing a solution consisting essentially of water and sea salt. The solution preferably includes a dissolved skin conditioner, preferably a natural skin conditioner, such as oat grains. The solution is applied to any animal, by dipping, spraying or in an aqueous-based carrier such as a shampoo, in an amount and for a period of time sufficient to deinfest the animal. The composition can be applied in dry form to carpets or lawns where animals lie to prevent infestation or reinfestation of the animal.

Abstract: Methods for treating animals infested with ectoparasites are provided for. The methods comprise providing a solution consisting essentially of water and sea salt. The solution preferably includes a dissolved skin conditioner, preferably a natural skin conditioner, such as oat grains. The solution is applied to any animal, by dipping, spraying or in an aqueous-based carrier such as a shampoo, in an amount and for a period of time sufficient to deinfest the animal.

Abstract: The present invention relates to processes and agents for combating fleas on, and in the surroundings of, domestic animals, which is characterised in that the domestic animals are treated with collars which contain active compounds which inhibit insect development.

Abstract: Annoying insects are controlled by attaching an insect control device to the body of the animal to be treated. The insect control device is a molded article, preferably in the form of an ear tag, which has been formed from a powder mixture of coumaphos, polyvinyl chloride and a plasticizer. The coumaphos is generally used in an amount such that from about 5 to about 30 wt % of the device is coumaphos. Other materials such as lubricants, pigments, stabilizers, etc. may also be included in minor amounts. The device may be formed by any appropriate technique but injection molding has been found to be particularly advantageous.
