Abstract:
Two repellents includes Iranian and Merck dimethyl phthalate
(DMP) were evaluated against Anopheles stephensi and Culex pipiens,
using American Society for Testing and Material (ASTM) standard ED 951-83
procedure, a free choice method based on the variable dose-fixed time.
Also a modified of ASTM method we used for determination of effective
dosages of the repellents. In ASTM method there were no significant differences
between the two repellents (Iranian and Merck's DMP) as indicated by the
ED50 and ED95 values (p>0.05). But, there were
significant differences in repellent sensitivity between An. stephensi
and Cx. pipiens at the ED95 level. In modified ASTM
method there were no significant differences between the two repellents
against An. stephensi, as indicated by the ED50 values
(p>0.05). But, there are significant differences between the two repellents
against Cx. pipence based on ED50 value. Results of
this study showed that the Iranian synthesized DMP has necessary potential
and specificity to compare with Merck manufactured product.
