Conditions for pycnidial production and spore formation by Ampelomyces quisqualis
Canadian Journal of Microbiology, 1990On Czapek agar medium, the optimum temperature for spore germination and pycnidia formation by Ampelomyces quisqualis was 20 and 25 °C, respectively. Inoculation of Czapek agar medium with a spore concentration of 106 or 107/mL significantly increased pycnidia formation as compared with medium inoculated with 104 or 105 spores/mL.

Ampelomyces quisqualis Ces., ein Parasit auf Mucorineen
Archiv f�r Mikrobiologie, 1968Ampelomyces quisqualis Ces., ein bisher fur Mucorineae noch unbekannter Parasit, wurde in seiner Entwicklung und seinem Befallsbild untersucht. Neun Gattungen der Mucoraceae und vier Gattungen anderer Mucorineen-Familien wurden durch Infektionsversuche auf Agar-Platten (Ausnahme Actinomucor) getestet.

OCCURRENCE OF AMPELOMYCES QUISQUALIS ON THE CUCURBIT POWDERY MILDEW SPECIES IN THE CZECH REPUBLIC
Acta Horticulturae, 2010From 2002 to 2006, in the Czech Republic (CR), 585 leaf samples with powdery mildew symptoms collected from cucurbits (mainly from Cucurbita pepo, Cucurbita maxima, Cucumis sativus) were microscopically examinated for presence of hyperparasitic fungus Ampelomyces quisqualis Ces. (Aq).

Stimulation of conidial germination of the hyperparasite Ampelomyces quisqualis
2014This research has focused on novel tools for exploring future application of A. quisqualis in biological control of powdery mildew. For this purpose, identification of specific mechanisms to increase the biocontrol efficiency is considered to be a good method. Thus, some attempts were made to enhance the efficacy of different strains of A.

Ampelomyces quisqualis for Biological and Integrated Control of Powdery Mildews in Israel
Journal of Phytopathology, 1989AbstractAn isolate of Ampelomyces quisqualis obtained from a Oidium sp. infecting Catha edulis in Israel, proved to be infective to several powdery mildew fungi belonging to the genera Oidium, Erysiphe, Sphaerotheca, Podosphaera, Uncinula, and Leveillula. In field trials, A.

Water agarose medium for studying factors affecting germination of conidia of Ampelomyces quisqualis
Mycological Research, 1997On water agarose conidial germination of Ampelomyces quisqualis was greatly enhanced in the presence of powdery mildew conidia. All seven species of powdery mildews tested, representing five genera, were effective in increasing germination of the mycoparasite.

Control of cucumber powdery mildew by the hyperparasite Ampelomyces quisqualis and fungicides
Plant Pathology, 1982Application of conidial suspensions of the hyperparasite Ampelomyces quisqualis to greenhouse cucumbers inoculated with Sphaerotheca fuliginea increased cucumber yield compared with an untreated control.

Temperatures significantly influenced the growth rate of the colonies and the highest radial growth rate was measured at 20°C for all strains. Interestingly, original climate at which A. quisqualis was isolated did not influence an adaptation to the temperature. In fact, strains isolated in countries with a warm climate grew well at low temperature and

Conidia of Ampelomyces quisqualis are able to infect powdery mildew but they must be supplied with exogenous nutrients before they are able to germinate. In the present study, conidia of three genetically different strains of A. quisqualis were stimulated by different carbon and nitrogen sources and results showed nutritional supplements at various ...
