Pyriproxyfen (Nylar), a juvenile hormone analog (JHA), and acephate were used in a German cockroach, Blattella germanica (L.), management program. Monthly applications of acephate for 6 mo reduced nightly trap catches from 24.68-25.25 to 4.46-5.31 at 2 mo, and trap catches averaged 1.49-8.04 from 2-6 mo. After acephate applications were discontinued, trap catches increased from 6.86 at 7 mo to 28.08 at 12 mo. Pyriproxyfen was applied at months 0, 3, and 6. Monthly pyriproxyfen treatments were applied from 7 to 11 mo because, at month 6, only 21.00-27.30% of adults had wing twisting (one effect of pyriproxyfen exposure). These monthly applications resulted in 74.55-78.53% of adults with twisted wings in the German cockroach population at 12 mo. Trap catches in apartments treated with pyriproxyfen aerosol were significantly lower at 7, 8, 10, and 12 mo after the initial treatment than those that did not receive JHA treatment. At 7-12 mo, the pyriproxyfen residual spray did not significantly reduce German cockroach populations, but trap catches were consistently lower. German cockroach populations were sampled for 1 yr (from 13 to 24 mo) after pyriproxyfen applications were discontinued. Compared with those in apartments treated with acephate, trap catches in apartments treated with pyriproxyfen were significantly reduced from 12 to 18 mo after the initial treatment. At 18-24 mo, trap catches in apartments treated with pyriproxyfen aerosol were consistently lower than those treated with acephate, but these differences were not significant.
吡丙醚（蚊蝇醚），一种保幼激素类似物（JHA），与乙酰甲胺磷被用于德国小蠊（Blattella germanica (L.)）的防治方案中。连续6个月每月施用乙酰甲胺磷，在2个月时，夜间诱捕捕获量从24.68 - 25.25降至4.46 - 5.31，在2至6个月期间诱捕捕获量平均为1.49 - 8.04。停止施用乙酰甲胺磷后，诱捕捕获量从7个月时的6.86增加到12个月时的28.08。在第0、3和6个月施用吡丙醚。从7至11个月每月施用吡丙醚，因为在第6个月时，只有21.00 - 27.30%的成虫出现翅扭曲（吡丙醚暴露的一种效应）。这些每月的施用使得在12个月时德国小蠊种群中74.55 - 78.53%的成虫出现翅扭曲。用吡丙醚气雾剂处理的公寓中，在初次处理后的7、8、10和12个月，诱捕捕获量显著低于未接受保幼激素类似物处理的公寓。在7至12个月时，吡丙醚残留喷雾并未显著减少德国小蠊种群数量，但诱捕捕获量一直较低。在停止施用吡丙醚后，对德国小蠊种群进行了1年（从第13至24个月）的采样。与用乙酰甲胺磷处理的公寓相比，用吡丙醚处理的公寓在初次处理后的12至18个月诱捕捕获量显著降低。在18至24个月时，用吡丙醚气雾剂处理的公寓诱捕捕获量一直低于用乙酰甲胺磷处理的公寓，但这些差异不显著。
