Abstract:
    A method for knock down of injurious insects or for freeing a paticular environment therefrom by heating funigation comprises dipping a part of a porous absorptive wick in an insecticidal solution to allow it to absorb the solution and indirectly heating said wick around the top to fumigate the absorbed insecticidal solution, and exposing the insects to the vapor, the insecticidal solution being a C12-C18 aliphatic saturated hydrocarbon solution containing as an active ingredient 2-methyl-4-oxo-3-(2-propynyl) cyclopent-2-enyl chrysanthemate, the porous absorptive wick being prepared by caking a powdery inorganic substance with a binding agent and the porous absorptive wick being indirectly heated around the top to a temperature in a range of from l05 DEG to l30 DEG C.
