The number of Toxorhynchites r. rutilus eggs occurring in 20 ground-level oviposition traps was monitored daily for 14 days in an area of coastal oak/palm hammock forest in Florida. Ten of these ovitraps (modified 2-liter plastic soda bottles) were placed in contact with tree trunks, the others at least 2 m from the base of the nearest tree. There was no significant difference in the mean number of eggs observed in egg-positive ovitraps for either type of trap site. However, ovitraps abutting trees were egg-positive significantly more often than expected. This result is discussed in terms of the initial oviposition-site searching behavior of female Toxorhynchites.
