一个原型自动传播站局部污染产卵寻求容器居住的蚊子与昆虫生长调节剂，吡丙醚，在实验室中进行了测试。我们的测试对象是亚洲虎蚊，白纹伊蚊（Skuse）（双翅目：蚊科），城市物种，殖民小体积的神秘幼虫栖息地，是一个跳过产卵器，访问多个容器。该站包括一个蓄水池，以吸引怀孕的女性，这是连接到一个转移室，旨在污染来访的蚊子。该装置很容易通过使用玉米淀粉作为粘合剂的湿碎纸板模制而成。证明自动传播站的有效性必须满足的基本标准要求它能有效地吸引目标昆虫，将毒物转移到昆虫身上并使其扩散，以及促进毒物以致死浓度从昆虫转移到目标栖息地。笼实验表明，该单位是很容易接受的怀孕女性作为产卵地点。将吡丙醚浸渍的二氧化硅颗粒的粉末制剂粘附到来访的Ae.白纹伊蚊雌性（平均值：66个颗粒/雌性），尽管颗粒随时间丢失。在笼（2.2立方米）试验中，吡丙醚充电站导致100%抑制成虫出现，而在小房间（31.1立方米）试验，81%的出现抑制记录。还观察到吡丙醚从受污染的雄性向处女雌性的性病转移，吡丙醚随后转移到盛水容器中，浓度抑制出现。自动传播站的主要特点包括无需维护、可生物降解的建筑、低成本和低风险。
A prototype autodissemination station to topically contaminate oviposition-seeking container-dwelling mosquitoes with the insect growth regulator, pyriproxyfen, was developed and tested in the laboratory. Our test subject was the Asian tiger mosquito, Aedes albopictus (Skuse) (Diptera: Culicidae), an urban species that colonizes small-volume cryptic larval habitats and is a skip ovipositor that visits multiple containers. The station consists of a water reservoir to attract gravid females, which is joined to a transfer chamber designed to contaminate visiting mosquitoes. The unit is easily constructed by moulding wet shredded cardboard using corn starch as a binder. The essential criteria that must be met to prove the efficacy of an autodissemination station require it to demonstrate effectiveness in attracting the target insect, in transferring the toxicant to the insect that will disperse the agent, and in facilitating the subsequent transfer of the toxicant from the insect to target habitats at a lethal concentration. Cage experiments demonstrated that the unit was readily accepted by gravid females as an oviposition site. A powder formulation of pyriproxyfen-impregnated silica particles adhered to visiting Ae. albopictus females (mean: 66 particles/female), although particles were lost over time. In cage (2.2 m3) trials, pyriproxyfen-charged stations resulted in 100% inhibition of adult emergence, whereas in small-room (31.1 m3) trials, 81% emergence inhibition was recorded. The venereal transfer of pyriproxyfen from contaminated males to virgin females was also observed, and pyriproxyfen was subsequently transferred to water-holding containers at concentrations that inhibited emergence. Key autodissemination station features include lack of maintenance requirements, biodegradable construction, low cost and low risk.
