Abstract: This study tested the ovipositional response of Cx. pipiens pallens to five species of plants and their volatiles:Acorus tatarinowii, Hydrocotyle vulgaris, Houttuynia cordata Thunb, Myriophyllum aquaticum (Vell.) Verdc. and Mentha spicata. The results showed that the oviposition activity index (OAI) value of Acorus tatarinowii was +0.58 with an effective repellency (ER) of 0%; Hence, Acorus tatarinowii can be considered as an oviposition attractant/stimulant. The OAI of Hydrocotyle vulgaris, Houttuynia cordata Thunb, and Myriophyllum aquaticum (Vell.) Verdc were measured as -0.70, -0.64 and -0.16 with an ER of 82.46%, 78.36% and 27.05%, respectively. Among these, Hydrocotyle vulgaris and Houttuynia cordata Thunb can be considered as repellents/deterrents. Meanwhile, the OAI of Mentha spicata was -1.00 with an ER of 100%, i.e., the strongest inhibiting effect, and hence considered the most suitable plant for repelling mosquitos. According to correlation analyses, there were significantly negative correlations between benzenoids and OAI values (p < 0.05). Terpenes, especially monoterpenes, had a significant positive correlation with OAI values (p < 0.05). This study provides a basis for the synergetic development of river ecological restoration and mosquito control.
