In one aspect, the present invention is directed to an ampoule for the storage and dispersion of a volatile liquid comprised of (a) an outer shell composed of an impermeable material and defining at least one opening (b) a porous diffusion member defining an internal reservoir positioned inside said outer shell (c) a volatile liquid contained within such internal reservoir and (d) a film member adhered to said outer shell and covering said at least one opening wherein said film member is disposed such that an air space is present between said porous diffusion member and said film member and wherein said porous diffusion member is configured such that molecules of the volatile liquid can only enter into said air space via diffusion through said porous diffusion member. Such ampoules are particularly suited for the storage and dispersion of organic chemicals useful as bed bug attractants, especially where such attractants are formulated in a highly volatile liquid, such as a C8-C12 alkane. In another aspect, this invention is directed to a device adapted to receive one or more of such ampoules. In one preferred embodiment, such device is a bed bug capturing device.本発明の1つの観点である揮発性液体の収容および散布のためのアンプルは、(a)不透過性材料を含有し少なくとも1つの開口を規定している外郭、(b)外郭の内側に配置され内部リザーバを規定している多孔性散布部、(c)内部リザーバ内に含有される揮発性液体および(d)外郭に付着され当該少なくとも1つの開口を覆うフィルム部を備え、フィルム部は多孔性散布部とフィルム部との間に空間が存在するように配置され、多孔性散布部は揮発性液体の分子が多孔性散布部を通り抜け散布を経た際のみ空間内に入ることが可能であるよう構成されている。当該アンプルは、南京虫誘引物質としての有機化合物、特に、C8-C12アルカンのような高い揮発性液体中に処方されるものの収容および散布に向いている。本発明のもう1つの観点は、少なくとも1つの前記アンプルを受容するよう適合された装置であり、南京虫捕獲装置が好ましい。【選択図】図1
