Extract

In research on fumigants it was found that variations in the proportions and amounts of the normal atmospheric gases (oxygen, nitrogen, and carbon dioxide), both during and after exposure to the toxicant, had profound effects on the mortality responses of the insects.

At reduced pressures (vacuum fumigation) the mortality response of the insects is complex (Monro 1959). With certain insects at least four zones of differing susceptibility were found. These are typified by the case of the cadelle, Tenebroides mauritanicus L.
