A Simple Spore Trap

Abstract

WHEN studying an air-borne plant pathogenic fungus, it is often desirable to determine whether the spores of the organism are present in the atmosphere at particular times. When accurate data suitable for statistical analysis are required, the use of apparatus such as the Hirst¹ spore trap is desirable. However, lack of funds or the absence of need for elaborate data may preclude such a purchase. The alternative would seem to consist of placing suitably treated microscope slides in a fixed position—a method known to be relatively inefficient. In seeking a compromise, the following spore trap was designed.
