Pyrethroids are commonly used in barrier treatments but less is known about how mosquitoes are affected by the simultaneous application of an insect growth regulator (i.e., pyriproxyfen) used in barrier treatments. This field study, conducted from May 14 - October 16, 2018, evaluated the effect of lambda-cyhalothrin (pyrethroid adulticide) and pyriproxyfen on the reproduction (measured by fecundity and adult emergence) and abundance of Aedes albopictus. Nine properties were treated with Demand®CS 0.06% + Archer® 0.010% (every 60 days) and three control properties received no treatment (N=12 total properties). No significant (P>0.05) differences were observed between abundance of Ae. albopictus in treatment compared to control groups. However, significant differences were observed in abundance of Ae. albopictus adults between weeks at both control (P = 0.003) and treatment (P < 0.0001) properties. Results from our research show that continued studies are needed to determine the efficacy of barrier treatments for this species. .
拟除虫菊酯通常用于屏障处理，但对于蚊子同时受到屏障处理中使用的昆虫生长调节剂（即吡丙醚）的影响知之甚少。这项于 2018 年 5 月 14 日至 10 月 16 日进行的实地研究评估了氯氟氰菊酯（拟除虫菊酯成虫防治剂）和吡丙醚对登革热白纹伊蚊繁殖（通过生育力和成虫出现来衡量）和丰度的影响。9 处物业用 Demand®CS 0.06% + Archer®0.010%（每 60 天一次）处理，3 处对照物业未处理（总共 12 处物业）。在处理组与对照组相比，白纹伊蚊的丰度之间未观察到显著差异（P>0.05）。然而，在对照组（P=0.003）和处理组（P<0.0001）物业的几周内，白纹伊蚊成虫的丰度存在显著差异。我们的研究结果表明，需要继续研究来确定该物种的屏障处理的效果。
