Representatives of many diverse groups of protozoa have associations with insects. These associations range from phoresis to obligate parasitism and in many instances insect mortality is the final result. Some symbiotic protozoa found in the gut of insects (e.g., termites, wood roaches) are important for the well-being of their bearer, while other forms seemingly innocuous for the insect carriers cause serious diseases in man and domestic animals (e.g., Trypanosoma).
