Four new insect growth regulators (IGRs) and a slow-release formulation of a currently-used IGR were evaluated for the control of Culex peus and Cx. quinquefasciatus in dairy wastewater lagoons. The IGR AC-291898 (CME 13406) proved highly efficacious, producing 100% control for one week and about 98% control for two weeks at the rate of 0.05 lb AI/acre (0.056 kg/ha). The IGR XRD-473 produced similar results at this rate. The effective rate of these two compounds seems to be in the range of 0.05 to 0.1 lb AI/acre (0.056-0.11 kg/ha). A granular formulation of S-31183 (0.5 G) applied at 0.05 lb AI/acre (0.056 kg/ha) yielded mediocre reduction whereas fenoxycarb EC 1 at up to 0.25 lb AI/acre (0.28 kg/ha) and methoprene 4% slow release pellets at up to 1.0 lb AI/acre (1.12 kg/ha) produced little or no control of Culex in the dairy wastewater lagoons. These compounds need to be applied at higher rates or suitable formulations will have to be developed to achieve satisfactory control.
对四种新型昆虫生长调节剂（IGRs）以及一种目前使用的IGR的缓释制剂进行了评估，以控制奶牛场废水氧化塘中的致倦库蚊和五带淡色库蚊。IGR AC - 291898（CME 13406）被证明具有高效性，以0.05磅活性成分/英亩（0.056千克/公顷）的用量，能实现一周100%的防治效果以及两周约98%的防治效果。IGR XRD - 473在此用量下产生了类似的结果。这两种化合物的有效用量似乎在0.05至0.1磅活性成分/英亩（0.056 - 0.11千克/公顷）范围内。以0.05磅活性成分/英亩（0.056千克/公顷）的用量施用的S - 31183（0.5 G）颗粒制剂产生了中等程度的防治效果，而高达0.25磅活性成分/英亩（0.28千克/公顷）的苯氧威乳油1以及高达1.0磅活性成分/英亩（1.12千克/公顷）的4%甲氧普烯缓释颗粒对奶牛场废水氧化塘中的库蚊几乎没有防治效果。这些化合物需要以更高的用量施用，或者必须开发合适的制剂以实现令人满意的防治效果。
