Sexuality And Other Features Of The Flagellates Of Cryptocerus

Uses microscopic photography to show the great diversity of the complex types of symbiotic protozoan flagellates that fill the hind-gut of the wood-feeding cockroach 'CRYPTOCERUS PUNCTULATUS.' Illustrates how ecdysone, the growth and differentiation hormone produced by the prothoracic glands of the cockroach, changes the type of reproduction in the flagellates from asexual to sexual.
