Discussion
Schreck and McGovern (1989) found that 12% deet in ethanol prevented Ae. albopictus bites for 6 h.Frances et al. (1993) showed that various formulations of 20-50% deet repelled Ae. albopictus for 3-4 h. Our results for Ae. albopictus corroborate these findings,given the 5 and 7.2 h eMPTs, respectively, for 7 and15% deet. They also showed deet to be an effective repellent against Cx. nigripalpus and Oc. triseriatus.
The only nondeet synthetic repellent we tested was Autan. Autan provided longer eMPTs against Cx. nigripalpus and Oc. triseriatus than 7 and 15% deet .Against Ae. albopictus, Autan provided an eMPT comparable with 7% deet (Skinsations) but less than that for 15% deet (Off!).
參考答案:讨论
Schreck和McGovern (1989) 发现二乙基-3-甲苯酰胺（驱蚊胺）的12%乙醇溶液对白纹伊蚊叮咬的防护时间为6小时。 Frances 等 (1993) 表明various formulations of 20-50%驱蚊胺的各种剂型对白纹伊蚊叮咬的防护时间为3-4 小时。我们对白纹伊蚊的测试结果和这些发现相关性很大，7 ％和15% 的驱蚊胺分别得到5 和7.2小时的平均防护时间。他们的实验也表明驱蚊胺也是白纹库蚊和三齿骚扰蚊的高效驱避剂。
我们测试的唯一一种不含驱蚊胺的人工合成驱避剂是“Autan”。 Autan对于环纹库蚊和三齿骚扰蚊的平均防护时间比7 ％和15%驱蚊胺要长一些。而对于白纹伊蚊，Autan的 平均防护时间和7 ％驱蚊胺相当(商品名Skinsations) ，但是比15%驱蚊胺要短 (商品名Off!)。
