Abstract
Protozoan parasites of insects are a heterogenous group of single-celled eukaryotes with prodigiously varied characteristics and little taxonomic affinity between groups. Although many species in several taxa are common and primary pathogens of arthropods, few protozoan groups have been used in microbial control programs because certain fundamental characteristics inhibit their use. These include complicated life cycles, some with intermediate hosts, obligate parasitism, and typically chronic rather than acute effects on their hosts. The expense of in vivo production, low persistence in the field, and difficulties in long-term storage add to the difficulties (Brooks, 1988).
