| laboratory evaluation of lagenidium giganteum (oomycetes: lagenidiales) in water from contra costa county, california, mosquito sources. | six bioassays were performed to evaluate the efficacy of the fungus, lagenidium giganteum, against mosquitoes in water collected from 75 sources. the fungus infected larvae of 4 genera and produced greater than 90% mortality in water from some of the creeks, artificial containers and the wild rice field tested during 4 of the assays. there was no larval mortality due to the fungus in water from irrigated pastures or marshes. water quality parameters associated with l. giganteum infection varied ... | 1990 | 1969930 |
| ground and aerial application of the asexual stage of lagenidium giganteum for control of mosquitoes associated with rice culture in the central valley of california. | a series of ground and aerial applications of lagenidium giganteum, a facultative fungal parasite of mosquito larvae, was made in rice fields and associated habitats in the sacramento valley, ca. initial trials using ground applications of the fungus in 400 m2 plots indicated that asexually competent mycelium from 30 liters of fermentation beer per hectare was sufficient to control culex tarsalis in rice field habitats. two multi-hectare applications using a micronair atomizer were made at rates ... | 2010 | 2904938 |
| temperature and water quality effects in simulated woodland pools on the infection of culex mosquito larvae by lagenidium giganteum (oomycetes: lagenidiales) in north carolina. | asexual stages of the california (ca) isolate of lagenidium giganteum cultured on sunflower seed extract (sfe)-agar, were applied to outdoor pools containing culex larvae near raleigh, nc in august and september 1984. infection rates among the larvae ranged from 19 to 74% at 2-4 days posttreatment and subsequent epizootics eliminated most of the newly hatched larvae for at least 10 days posttreatment. substantial reductions in numbers of larvae and adult emergence were achieved from a single app ... | 1987 | 3504911 |
