Abstract

Abstract Liposcelis entomophilus (Enderlein) was maintained on diets composed of various combinations of wheat flour, skimmed milk powder and yeast. After 6 weeks, a diet comprising the above components in 10:10:1 proportions respectively resulted in the highest increase in liposcelid population ( P < 0.05). Subsequently, L. entomophilus was successfully cultured on this medium at 30 ± 1°C and 72–78% r.h. A method for maintaining stock cultures was established. The use of an aspirator in the handling of these liposcelids was tested and proved adequate, the optimum suction pressure being 60 mmHg ( P < 0.05). A separating sieve, used with a 60 W incandescent bulb, was specially constructed to extract these liposcelids from infested grains. Modifications to this apparatus and its other uses are discussed.
