Resumen:
Abstract: Effect of water quality in mosquito breeding sites on the pathogenicity and infectivity of zoospores
from the fungus Leptolegnia chapmanii (Straminipila: Peronosporomycetes). The fungus Leptolegnia
chapmanii is highly pathogenic to mosquito larvae in Argentina. We studied if physical and chemical characteristics
of the water from mosquito breeding sites affect pathogenicity, and the infectivity of zoospores of L.
chapmanii. Water samples were taken from pools filled by rains, urban ditches with domestic waste water, pools
filled by overflow from Río de la Plata, and flower vases from the Cemetery of La Plata city. Sub-samples of
water were analyzed for physical and chemical characteristics, while other sub-samples were used for laboratory
bioassays. Containers with 150 ml of water samples, 25 Aedes aegypti larvae, and 2.8 x 105 zoospores of
