 note = {Permeability of insecticides by infusion treatment was tested with wooden pieces filled with insect feces or frass of Priobium cylindricum. Six types of insecticides (one water soluble, and five water insoluble［oil solution and emulsion］) commercially produced by two companies were selected.
 Treatments were conducted in three ways. 1)Perforation hole with a 3 mm diameter and approximately 11 cm depth was prepared, and insecticides were injected into the hole with a high pressure injector. 2)Perforation hole with a 13 mm diameter and approximately 15 cm depth was prepared, and insecticides were directly poured into the hole. 3) Insecticides were applied to the surface of the radial section with a brush. Permeability of the insecticides was checked by cutting the treated wooden pieces with a horizontal plane and visually observing the area where insecticides had permeated.
 When the insecticides were directly poured into the hole,oil solutions permeated faster than emulsions. Compared with emulsions, permeation of oil solutions was 2 to 3 times more in volume. Emulsions remained in the bottom of the hole after 2 to 3 hours. When a cross section was observed,it was found that the insecticides had spread approximately 2-3 mm around the hole. Even at places filled with insect feces or frass, the insecticides had also spread. When the insecticides were injected with a high pressure injector,the speed of permeability was faster than when the insecticides were directly poured. However, the insecticides overflowed from the insect holes. When a cross section was observed, it was found that the insecticides spread approximately 2-3 mm around the hole just as when insecticides were directly poured. Even at places filled with insect feces or frass, the insecticides had also spread. When the insecticides were applied to the surface with a brush, the insecticides permeated approximately 4-5 mm from the surface of the radial section. Permeability of the insecticides seems to be dependent on their chemical characteristics.
 Further research is necessary to develop effective treatments using insecticides for conserving wooden historical buildings.},
