[ efficacy of Iranian and foreign dimethyl phthalate lotion and trench oinment against Anopheles stephensi in laboratory conditions]

Background: The use of repellents is an important mean of personal protection against biting insects, as well as for combating diseases transmission by reducing man-vector contact. Although N, N- diethyl-3-mtoluamide [DEET] has effective and commonly used, but a number of biting Diptera are tolerant to DEET. In addition, there are some concerns about the safety of DEET and their allergic and toxic effects. Therefore, attend to other repellents. This study evaluated dimethyl phthalate [DMP], which was synthetized in Iran, for protection time [PT] against Anopheles stephensi and compared its efficacy whit two repellents foreign DMP and Trench oinment, under laboratory condition

---

Materials and methods: This study was conducted to determine the repellent protection time and failure time [FT] by Barnard [1999] method

---

Results: Our results indicated that PT of Iranian DMP against An.stephensi was 274+/- 8.04 which is no significant differences whit two others repellents. There were significant differences in FT among three repellents. The FT of Iranian DMP was significantly less than two other repellents

---

Conclusions: Iranian DMP lotion is comparable with foreign DMP lotion, but it needs to promote and to be increased repellent FT
