Studies of the infection of the cockroaches (Blattella germanica[L.]) with Bac. thuringensis.
The results of an experimental infection of the cockroaches Blattella germanica (L.) with some trade preparations containing Bac. thuringensis spores are presented. Biological studies supported by bacteriological and histological examinations of the excised intestines of the above insects have shown that the microorganisms studied are pathogenic for the cockroaches. This effect might be eventually applied as a biological method of eradication of the cockroaches in such environments, where chemical preparations can not be used or this disinfestation method would be complementary to the other method of disinfestation.
