Release of Romanomermis iyengari (Nematoda:Mermithidae) to control Aedes taeniorhynchus (Diptera:Culicidae) in Punta del Este, Isla de la Juventud, Cuba.
Preparasites of Romanomermis iyengari Welch were applied at the rate of 1,000 preparasites per square meter of surface area in 5 natural breeding sites in carbonate rock depressions to control Aedes taeniorhynchus Wiedeman larvae. Larval parasitism averaged 100, 97, 81, and 80% in 1-4 instars, respectively. Three of 5 sites produced parasitism in excess of 90%. The range of salinity and water depth had little influence on the levels of parasitism. Ae. taeniorhynchus density was reduced from 78 to 96% at the 5 sites 8 d posttreatment.
