 An isolate of Argentina of Leptolegnia chapmanii (ARSEF 5499), was tested against 12 species of native mosquito species and on species of non target aquatic invertebrates and vertebrates.The mosquito species tested were Aedesa aegypti, Anopheles sp., Culex apicinus, Cx. castroi, Cx. dolosus , Cx. pipiens , Cx. renatoi, Isostomyia paranensis , Ochlerotatus albifasciatus , Oc. crinifer, Psorophora cyanescens and Ps. ferox . Mosquito larvae of 10 species were susceptible with mortality from 10- 100 % . Two mosquito species Cx renatoi and I. paranensis were not infected by Leptolegnia. None of the non- target fauna treated was infected by L. chapmanii with exception of members of the family Chironmidae which were susceptible at low infection rates.
