Abstract

UNLABELLED

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 t-test 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.

目的和材料及方法：在实验室条件下，测定邻苯二甲酸二甲酯（DMP）处理腕带对蚊子的驱避效果，即利什曼按蚊、埃及伊蚊、库蚊。DMP 处理腕带对不同蚊种表现出不同程度的驱避作用。

结果

在 1.5（81.1%）和 2.0 mg/cm2（87.0%）两种浓度下，对按蚊的登人率降低率较高。在浓度为 1.5 和 2.0 mg/cm2 时，对库蚊的保护率分别为 79.8%和 84.8%。在浓度为 1.5 和 2.0 mg/cm2 时，对埃及伊蚊的登人率降低率分别为 74.4%和 86.5%。t 检验结果证实了对控制组和每个实验组的登人率降低率的评估。t 检验结果显示，在 1.5 mg/cm2（p = 0.0026；t = 19.2；df = 2）和 2.0 mg/cm2（p = 0.0025；t = 19.8；df = 2）时，降低与人为媒介接触的作用极其显著。
