A topical insect repellent with extended duration of protection was obtained from mixtures of molecules based on two or more volatile repellent organic molecular species occurring naturally on the human skin surface. The novel repellent comprises mixtures of lower, intermediate, and higher volatility organic molecules. Active ingredients for formulations are obtained from homologous series of carboxylic acids, alcohols, ketones, and lactones which span a similar range of volatility and which occur naturally on the skin surface. Volatile silicone fluid imparts mildness and water repellency to the repellent formulations. The new natural repellent exhibits the longevity and repellency that is comparable to N,N-diethyl-m-toluamide (DEET), a synthetic compound employed in almost all commercial formulations, but the inventive natural repellent is more acceptable than DEET, which has an unpleasant odor and imparts a greasy feel to the skin. The inventive insect repellent, formulated in a volatile silicone fluid, was shown to repel and incapacitate stable flies. This finding demonstrated that repellency was not limited to mosquitoes, but extends to other biting flies or insects, thus demonstrating the utility of the novel insect repellent for protecting pets and livestock as well as humans.

The present invention relates to the discovery of a novel endophytic fungus, Muscodor vitigenus, from the liana, Paullinia paullinioides. This fungus produces naphthalene under certain cultural conditions that has chromatographic and mass spectral properties that are identical to authentic naphthalene. In a preferred embodiment, the naphthalene in the gas phase of M. vitigenus is useful in the repellency of unwanted insect pests. The unique biological activity of the novel endophyte suggests a wide range of potential practical applications, particularly in the area of insect repellents, insecticides, antimicrobials, anthelmintics and vermicides.

Disclosed herein are wearable devices for dispensing insect repellents, fragrances, and/or other chemicals along the outside of the clothing of a human, to avoid the need to apply such chemicals directly to clothing or to human's skin. The devices have an on/off switch that automatically controls a shutter which enables and restricts air flow, while also controlling fan operation and covering of a use-up cue. The device also is designed to prevent fan operation when an impregnated slab is not present. Also disclosed are preferred refills for use with such devices.

An integrated system to reduce the entry of flying insects into a predefined area; the system includes a plurality of insect management devices that can act as flying insect traps or flying insect repellants that are controlled either remotely via radio signals or through wires, by a micro controller that utilizes several environmental variables such as current wind speed, wind direction, rainfall, humidity, and other variables to then control the release and/or generation of attractants and/or repellents only to selected insect management devices around the predetermined area to be protected. Insect attractant and/or repellant is pumped underground from a central source to selected insect management devices.

Disclosed is an insect repellent composition. The composition has an amount of an insect repellent active effective to repel insects when the composition is applied to the skin, and an amount of a urethane polymer sufficient to form a film on the surface of the skin. The composition also has a cosmetically-acceptable vehicle. Also disclosed is a method of repelling insects from the skin by applying the composition to the skin.

Multi-layer reaction mixtures that includes exothermic generating particles having a water soluble coating encasing a portion of the particles, a volatile component and, optionally, a buffer, an aqueous solution or both. At least two layers of the reaction mixture contain exothermic generating particles and at least one layer of the reaction mixture contains a portion of the exothermic generating particles suspended in a gel that includes the water soluble coating. These multi-layer reaction mixtures are especially suited to generate heat in a controllable manner. In one such controlled reaction, the reaction components are mixed together and the reaction mixture increases in temperature to a Set Temperature within a predetermined time, and the mixture remains at the Set Temperature for a longer period of time. In this manner, volatile components can be controllably released to the surrounding environment. The volatile components can be, for example, a perfume, a fragrance, an insect repellent, a fumigant, a disinfectant, a bactericide, an insecticide, a pesticide, a germicide, an acaricide, a sterilizer, a deodorizer, a fogging agent and mixtures of these. Apparatuses and methods that use these multi-layer reaction mixtures are also disclosed.
