Badanie laboratoryjne aktywności szczepu owadobójczego grzyba Paecilomyces farinosus w redukcji liczebności prusaków Blatella germanica L.
[Laboratory determination of the activity of insecticidal fungus Paeciomyces farinosus in reduction of Blatella germanica L.]

K. Żukowski, С. Bajan


The strains of P. farinosus capable of killing the cockroach Blattella germanica L. were selected. The experiment was carried out using mature insects in age groups and sex groups. The results showed differences in the insecticidal capability of the tested strains in this population of insects. Strains 5, Ł, P of P. farinosus were accepted as possibly useful against Blattella since at relatively low concentration of spores they produced a high mortality of the insects.
