Abstract
Inoculative releases of Toxorhynchites splendens (Wiedemann) were conducted of the cities of Sarasota, Tallahassee, Panama City, and Panama City Beach, FL, in 1989 and 1990. In 1989, painted 473-ml little black jars were used to monitor T. splendens oviposition. T. splendens larvae were found in 88–100% of the jars within 3 wk of release periods but were never recovered at longer intervals. Significantly fewer eggs of pest mosquitoes were recovered from a site receiving both ultralow volume (ULV) applications of malathion and T. splendens than the site receiving ULV alone. In 1990, although 45% of the artificially placed jars were colonized by T. splendens at both sites following releases, natural container colonizations were below 10%. Apparent predation of resident pest mosquitoes by T. splendens within the little black jars over the entire 1990 study was not statistically significant.
