Abstract The systematics of entomophthoraceous fungi which are pathogenic to insects (especially aphids), their development cycle (especially the production of infective conidia), mass production either by distribution of infected living or dead aphids on the crop or by laboratory culture on liquid or solid media, and greenhouse and field tests on mass-produced fungi for the control of aphids are reviewed. Resting spores of these fungi could be produced quite easily in liquid culture, but those of Conidiobolus thromboides did not kill aphids and those of C. obscurus required incubation for 4 months in moist clay at 4 deg C before germination occurred. Erynia neoaphidis, which does not produce resting spores, could be distributed in living or dead aphids or cultured in liquid media, but multiplied very little on aphids killed in the field and was therefore not available to infect the next generation. Investigations are in progress on means of improving the survival of fungal inocula in storage and of applying fungi repeatedly as an insecticide rather than relying on natural spread for pest control.
