The present invention relates to the field of pest control and in particular to a device (1) for controlled release and/or sustained release of the volatile substance to attract and control diptera comprising a container (2) having an opening (2a) that can have a sealing media (3) suitable to close and seal said opening (2a), wherein both the container (2) and the sealing media (3) are made of a polymeric material. The invention also relates to a method to attract and/or control diptera using said device (1).

A plug is attachable to a wall of a torch that is configured to burn a liquid fuel. The plug adds one or more features to the torch, such as a fuel level sensor, a temperature sensor, a tilt sensor, an automatic wick ignitor and/or extinguisher, a wick clamp, a wick advancing mechanism, and/or a global positioning system. The plug includes an electronic controller, and wired and/or wireless electronics configured to provide remote control and/or monitoring of the added features. Power for the plug can be provided by a battery and/or a solar panel. The controller can establish a unique torch identity, thereby enabling a remote computing device to monitor and/or control features of a plurality of torches that each have a plug of the present disclosure attached thereto. The plug can be removably or permanently attached to the torch.

Provided is a sustained-release pheromone preparation that can be easily installed and stably retained in an installation location, and is comprised of at least one pheromone substance-containing polymer tube with both ends sealed or pheromone substance-containing polymer rod, wherein (a) a closed space is formed in a front view by bending in an arc and crossing the tube or rod, and the preparation is not crossed in a side view; (b) a curvature radius established is 4 to 17 mm; (c) a linear distance from a top point of an arc to a crossover point is 25 to 70 mm; and (d) a repelling force when opening the crossover point to establish a clearance of 20 mm in the front view is 0.5 N or larger.

Provided is a sustained-release pheromone preparation that can be easily installed and stably retained in an installation location, and is comprised of at least one pheromone substance-containing polymer tube with both ends sealed or pheromone substance-containing polymer rod, wherein (a) at least two closed spaces and an opening portion are formed in a front view by bending in an arc and crossing the tube or rod, and the preparation is not crossed in a side view; (b) a curvature radius established is 4 to 15 mm; (c) a linear distance from a top point of an arc to a crossover point that is closest to the top point is 10 to 50 mm; and (d) a repelling force when opening the crossover point that is closest to the arc to establish a clearance of 20 mm in the front view is 1.0 N or larger.

A refill for holding at least two compositions comprises a container including a body and first and second compositions disposed within the body such that the first and second compositions are substantially separated and the second composition is disposed above the first composition. The refill further includes a tube disposed within the body of the container such that the tube contains the first and second compositions, wherein the tube has an inner diameter and an outer diameter. Still further, the refill includes a wick disposed within the tube, wherein the wick contains the first and second compositions and has a diameter that is smaller than the inner diameter of the tube to create a gap between the wick and the tube.

A volatile composition dispenser includes a housing having opposing first and second walls that are joined along their peripheries to one another. The first wall has an aperture and the second wall has a plurality of apertures. Within the housing, rests a volatile composition cartridge and a gap, which exists between the cartridge and a bottom surface of the housing, wherein said bottom surface is formed from a joinder of a base portion of one or both of the first and second walls, and wherein, upon activation, the exposure percentage of the dispenser is from about 40% to about 90%; wherein at least about 60% of the total surface area of the plurality of apertures results from individual apertures of said plurality that each have an area of at least 30 mm.sup.2 and an aspect ratio of at least about 1:2. Dispenser of a similar housing, cartridge, and gap when is activated by a user and thirty days after said activation, exhibits about 70% to 90% weight loss of said volatile composition of a partially exposed membrane of a fully exposed membrane.

A refill comprises, a container having a body forming a reservoir and an opening in communication with the reservoir, a first composition disposed within the reservoir, a second composition disposed within the reservoir and substantially separated from the first composition, a single wick in contact with the first and second compositions and configured to sequentially emit the first and second compositions. A method of emitting the first and second compositions includes the steps of emitting the first composition until the first composition is substantially depleted and emitting the second composition after the first composition is substantially depleted.

The invention relates to an evaporation device for evaporating volatile substances, comprising a container (1) housing a liquid (8) containing the volatile substances, an outlet (2) through which the volatile substances exit and a hole (9) for equalizing the pressure between the inside and the outside of the container, and characterized in that it also comprises a membrane (6) placed between the container (1) and the hole (9), said membrane (6) being leak-tight with respect to said liquid (8) and porous with respect to the gases.

This membrane prevents the liquid from accidentally spilling and furthermore solves the issue of balancing pressures inside the container, keeping the rate of evaporation constant until running out of the volatile substances.

A volatile substance evaporation device includes a constant evaporation chamber (2) housing a liquid with volatile substances, an enhanced evaporation chamber (3) and an evaporation membrane (5) through which the volatile substances evaporate. The enhanced evaporation chamber (3) includes an absorbent body (6) therein. The inclusion of the absorbent body (6) enhances the evaporation rate in a simple manner and allows the enhanced evaporation to be substantially constant.
