Abstract:
Objectives and Materials and
Methods: The repellent efficacy of dimethyl phthalate (DMP) treated wristband was determined
against mosquitoes, viz Anopheles stephensi Liston, Aedes aegypti Linnaeus, Culex quinquefasciatus Say at two concentrations viz., 1.5 and 2.0
mg/cm2 under the laboratory conditions. DMP treated wristband had shown variable degrees of repellency impact against different mosquito species.
Results: Its offered higher reduction of man
landing rate against Anopheles stephensi at both
concentrations of 1.5 (81.1%) and 2.0 mg/cm2
(87.0%). 79.8% and 84.8% of protection achieved
against Culex quinquefasciatus at concentrations
of 1.5 and 2.0 mg/cm2
, respectively. 74.4 and 86.5%
of reduction of man landing rates were obtained
against Aedes aegypti at concentrations of 1.5
and 2.0 mg/cm2 respectively. The reduction of
man-landing rate evaluations were confirmed by ttest compared between control group and each
experimental group. The t-test result shows at 1.5
(p = 0.0026; t = 19.2; df = 2) as well 2.0 mg/cm2 (p =
0.0025; t = 19.8; df = 2) are extremely significant to
reduce the man vector contact.
Conclusion: The present data suggest that
DMP treated wristbands are most promising
against both day and night-biting mosquitoes and
significantly reducing the man-vector contact.
Therefore, it could serve as a potential as means
of personal protection device against insect nuisance biting and insect-borne disease when and
where other kinds of personal protection measures are impossible and impracticable.
