Abstract
A convenient, economical, non-toxic and effective apparatus for the control of roaches by administration of entomopathogenic fungi to the cockroaches. The roaches are exposed to the fungi in a contamination chamber having openings through which the cockroaches enter and come in contact with a living culture of a fungus which is pathogenic to cockroaches. The fungal spores attach to the roach, germinate and penetrate into the body of the cockroach, resulting in the death of the infected roach. Death takes approximately two to three weeks after contact with the culture. During this time, the infected roach disseminates spores of the pathogenic fungus throughout the infested areas which may subsequently infect other roaches. Given the proper environmental conditions, the fungus sporulates on the cadaver of the roach and the conidia can be transmitted to other cockroaches, resulting in a further spread of the disease.
