  • Patent number: 5057315
    Abstract: A convenient, economical, non-toxic and effective method and means for the control of roaches by administration of entomopathogenic fungi to the cockroaches. In the preferred embodiment, the roaches are exposed to the fungi by means of 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.

  • Patent number: 5057316
    Abstract: A method for control and extermination of insects, including roaches, flying insects such as the housefly, and other insects such as the adult form of the corn rootworm by infection of the insects with a fungus that can be pathogenic when administered to the insects in a sufficiently high concentration, by means of an infection chamber. The chamber maintains the spores of a fungus pathogenic to the insects in a viable form, protecting the fungi from the environment (including rain, ultraviolet light and the wind), serves as an attractant for the insects, and serves to inoculate the insects with high numbers of spores. Although the primary means of infection is by external contact, the insects may also be infected by contact with each other and by ingestion of the spores. The two most preferred entomopathogenic fungi are Metarhizium anisopliae and Beauveria bassiana, although other fungi can be used which are pathogenic when the insect is inoculated via the infection chamber.
