. As for the repellency
results against Cx. quinquefasciatus, the 18
essential oils demonstrated a relatively high
degree of repellency, ranging from 5.0 to 8.0
hours, while those of deet and lR3535 were
8.0 hours (Table 3). Unlike the effect against
An. dirus, excellent repellency against Cx.
quinquefasciatus was fot~nd in only three essential
oils, Curcuma longa (8.0 hours), Piper
nigrum (7.8 hours), and Schefflera leucantha
(7.5 hours), which were statistically equal to
those of deet and lR3535 (p >0.05).
