Pyriproxyfen (S-31183) was applied to dairy wastewater lagoons, during 1988, at 0.1 kg (AI)/ha in single and multiple applications which resulted in control of Culex spp. larvae for periods of 7 to 68 days. Length of the control period appeared to be related to water quality, with greater residual efficacy in more polluted sources. The AI apparently adsorbed onto organic debris where efficacy remained high in the lagoon even after water was pumped from the lagoon and replenished with untreated wastewater. Alternating treatments with control agents having a different mode of action is suggested to avoid selection of insecticide resistance.
1988年，吡丙醚（S - 31183）以0.1千克（有效成分）/公顷的用量单次或多次施用于奶牛场废水氧化塘，可控制库蚊幼虫7至68天。控制期的长短似乎与水质有关，在污染更严重的水源中残留药效更高。有效成分显然吸附在有机残渣上，即使从氧化塘抽水并补充未处理的废水后，氧化塘中仍保持较高药效。建议交替使用具有不同作用方式的控制剂，以避免产生抗药性。
