Given the lack of vaccines for most vector-borne diseases, vector control is often the primary option for disease control. Aedes albopictus are difficult to control because the immatures primarily develop in containers ubiquitous in residential properties. Conventional adulticide campaigns often result in brief, rebounding population declines, so incorporating new techniques into an integrated pest management program is imperative. We performed combined area-wide applications of the larvicides Bacillus thuringiensis var. israelensis and pyriproxyfen with the adulticide sumithrin and prallethrin to achieve extended suppression of Ae. albopictus populations in Trenton, NJ, USA. We deployed bioassay cups to assess the spatial penetration and efficacy of the applications.
Inhibition of adult emergence was significantly higher in the treatment bioassay cups than in laboratory controls (z = 4.65, P < 0.0001) and field control bioassay cups (z = 8.93, P < 0.0001). We observed a lower trend in adult numbers following season-long combined application of pyriproxyfen and adulticide, with numbers of adult Ae. albopictus at the treatment site up to five times lower than at the control site.

鉴于大多数虫媒病缺乏疫苗，因此病媒控制通常是疾病控制的主要选择。白纹伊蚊很难控制，因为其幼虫主要在住宅物业中普遍存在的容器中发育。常规的成虫杀虫剂防治活动通常会导致短暂的、反弹的种群下降，因此必须将新技术纳入综合虫害管理计划。我们在美国新泽西州特伦顿市联合开展了大面积应用苏云金芽孢杆菌以色列变种和吡丙醚的幼虫防治，以及使用增效醚和炔丙菊酯的成虫防治，以实现对白纹伊蚊种群的长期抑制。我们部署了生物测定杯来评估应用的空间渗透和效果。
处理生物测定杯中成虫出现的抑制率明显高于实验室对照（z = 4.65，P < 0.0001）和田间对照生物测定杯（z = 8.93，P < 0.0001）。在应用吡丙醚和成虫防治剂进行长达一个季节的联合应用后，成虫数量呈现出下降的趋势，处理地点的白纹伊蚊成虫数量比对照地点低五倍。
