We tested five volatile synthetic chemicals (dimethyl disulfide, indole, 4-methylphenol, 3-methylindole,and trimethylamine) as potential oviposition attractants of Aedes albopictus in field and laboratoryexperiments. The 5 synthetic compounds were loaded into controlled-release packets, which consisted of acellulose material sealed within a permeable plastic membrane, that were used to bait water-filled ovitraps at 5field sites. Aedes albopictus exhibited no oviposition preference for any of the baited traps versus adjacent trapscontaining only water. In addition, there was no difference in the mean number of eggs laid per trap-day by Ae.albopictus among ovitraps treated with the five compounds. We conducted behavioral bioassays to determine ifthe lack of response to the putative oviposition chemicals in the field was due to a concentration effect. A binarysticky-screen bioassay was, used to measure attraction of gravid females to olfactory stimuli. Compounds wereevaluated over a range of concentrations that spanned 3-5 logs (0.0083 to 8.3 or 83 mg/liter). Three concentrationsof 4-methylphenol (0.083 mg/liter, 0.83 mg/liter, and 8.3 mg/liter) and 1 concentration of 3-methylindole(8.3 mg/liter) were significantly repellent. All other concentrations of the 5 chemicals tested did not attract morefemales than did a water control. Electoantennography indicated that Ae. albopictus did not exhibit a physiologicalresponse to O.25 ng of any of the five chemicals tested. Because Ae. albopictus did not exhibit attiaition,greater oviposition, or an electrophysiological response to any of the compounds tested, these compounds donot appear to be effective lures for baiting ovitraps for surveillance or control of this mosquito.
