Abstract

The performance of bamboo leaf infusion (XLI) and ?X? leaf infusion (XLI) as oviposition attractant/stimulant was evaluated against Aedes aegypti in the laboratory under choice and no-choice methods utilizing one pair and 25 pairs of gravid females. Under choice method, significantly, highest average number of eggs were laid by a female alone in XLI (126.73), which correspond to 97.96% of the total eggs laid within the set up while significantly lowest number of eggs were laid in water and bamboo leaf infusion. The same trend in the oviposition preference of A. aegypti was observed when the solutions were exposed to 25 pairs of female except that slightly lower number eggs were laid in XLI but slightly higher in water and BLI. Under no choice method, both the presence of a female alone or 25 females laid significantly the same number of eggs whether in water, BLI or in XLI. Significantly higher average number of eggs was laid by a pair of adult than when 25 females were used. High number of eggs laid corresponded to high oviposition activity index (OAI) of each female in XLI with 0.97 in one-pair set up and 0.71 in 25-pair set up. Based on the percent attractancy rate, very low number of A. aegypti females transferred in the two leaf infusions but several modifications should be done to arrive at a more reliable results. Results of the study showed that XLI is a very potent oviposition attractant/stimulant to gravid female A. aegypti. Further study on XLI utilization for population monitoring and for attract and kill technology should be immediately pursued.
