Effect of ultraviolet-A radiation on the production of <i>Leptolegnia chapmanii</i> (Saprolegniales: Saprolegniaceae) zoospores on dead <i>Aedes aegypti</i> (Diptera: Culicidae) larvae and their larvicidal activity

Impact of UV-radiation in entomopathogens in aquatic environments remains little investigated. The present study reports on the effect of UV-A on the larvicidal activity of <i>Leptolegnia chapmanii</i> zoospores in <i>Aedes aegypti</i>; on the production of zoospores in larva...

description Impact of UV-radiation in entomopathogens in aquatic environments remains little investigated. The present study reports on the effect of UV-A on the larvicidal activity of <i>Leptolegnia chapmanii</i> zoospores in <i>Aedes aegypti</i>; on the production of zoospores in larvae killed by the pathogen and then exposed to UV-A; and on the activity of these zoospores against healthy larvae. Whereas the virulence of free zoospores in <i>A. aegypti</i> larvae was affected by a UV-A exposure time longer than 10. min, production of zoospores in larvae and their virulence were not hampered at a maximal 8. h exposure of dead larvae to UV-A. Findings suggest that dead larvae and zoosporangia provide a certain protection to zoospores against UV-A and emphasize the susceptibility of free encysted zoospores to such radiation.
