Since powdery mildews are obligate parasites, all the
previous studies on interaction of mycoparasite and its
powdery mildew host were carried out on the host of the
powdery mildew2,7,10). By incubating A. quisqualis conidia
together with powdery mildew conidia on glass
slides under moist conditions, parasitism of the mycoparasite
was shown for the first time outside the host.
This may be useful for studying factors affecting parasitism
of A. quisqualis on its powdery mildew hosts.
