The fungus was grown for 7 days in a liquid medium of wheat germ, hemp seed, yeast extract, and glucose, then placed onto hemp-seed agar. Zoosporogenesis was induced on agar by immersing the fungal cultures into water. Zoospore production began 10 hr postimmersion, peaked at 18 hr, and ceased by 36 hr. A single, 10-cm Petri dish of fungus on hemp-seed agar produced 1.7−3.8 × 107 zoospores during the 26 hr of zoosporogenesis. Optimal zoospore production occurred with 4- to 7-day-old cultures; cultures older than 10 days produced few zoospores. The temperature range for zoosporogenesis was 15–35°C. The extent of zoosporogenesis was directly related to the volume of water used to induce zoospore formation and inversely proportional to agar thickness. Bioassay of zoospores against second instar Culex quinquefasciatus larvae yielded an LD50 of 400 zoospores/ml.}, number={3}, journal={JOURNAL OF INVERTEBRATE PATHOLOGY}, author={JARONSKI, S and AXTELL, RC and FAGAN, SM and DOMNAS, AJ}, year={1983}, pages={305–309} } @article{jaronski_axtell_1983, title={Persistence of the mosquito fungal pathogen Lagenidium giganteum (Oomycetes; Lagenidiales) after introduction into natural habitats}, volume={43}, number={3}, journal={Mosquito News}, author={Jaronski, S. and Axtell, R.

In unpolluted water, the fungus infected 27–100% of Culex quinquefasciatus larvae, depending upon the size of the fungal inoculum, and persisted for 1 month until low water temperature inhibited fungal development. No infection occurred in water with low to moderate levels of organic pollution. With data obtained from laboratory tests of the effects of polluted water on zoosporogenesis and infection of larvae by the fungus, a multiple regression equation was developed relating levels of chemical oxygen demand (COD), total Kjeldhal nitrogen (TKN), ammonia nitrogen (NH3-N) and total phosphorus (P) to percentage infection of larvae under standardized, optimal conditions. The multiple regression, % Infection = 113.9 – 0.02 (mg/litre COD) – 1.92 (mg/1 TKN) ♂ 3.41 (mg/1 NH3-N) – 6.02 (mg/1 P), means that the infection rate decreased 0.2% for each additional mg/1 COD, 1.92% for each additional mg/1 TKN, 3.41% for each additional mg/1 NH3-N and 6.02% for each added mg/1 P, when all 4 parameters were considered simultaneously. Of the 4 parameters, only NH3-N and P were statistically significant predictors of pollution effects on infection of larvae by Lagenidium. The presence of organic pollution in the water prevented the formation of sporogenic vesicles by the fungus and drastically reduced the viability of any zoospores that were produced.}, number={3}, journal={JOURNAL OF MEDICAL ENTOMOLOGY}, author={JARONSKI, ST and AXTELL, RC}, year={1982}, pages={255–262} } @inproceedings{axtell_jaronski_merriam_1982, title={Efficacy of the mosquito fungal pathogen, Lagenidium giganteum (Oomycetes: Lagenidiales)}, volume={50}, booktitle={Proceedings and Papers of the Annual Conference of the California Mosquito and Vector Control Association, Inc.}, author={Axtell, R.
