Extract

It has been generally accepted by insect microbiologists and physiologists that many insects harbour beneficial micro-organisms. The contributions of Buchner (1933), Glaser (1946), Jeanne1 (1949), Steinhaus (1946), Wigglesworth (1950) and Woodward (1949) are relevant. Some experimental evidence has been contributed by Aschner 1935, Blewett and Fraenkel (1944), and Brecher and Wigglesworth (1944). It seems that the micro-organisms may sometimes supply the host with vitamins of the B group. (Blewett and Fraenkel). Many species of insects have special organs, called mycetomes, whose chief function seems to be the housing of micro-organisms. Furthermore it has been suggested that special arrangements exist for the transference of micro-organisms from one generation of insects to the next. (Mansour, 1935; Murray and Tiegs, 1935; and Woodward 1949).
