When posttreatment response to ultra low volume (ULV) application of insecticide has been followed for periods approaching a week, a damped oscillation in oviposition rates is observed, probably because females who have been recently blood-fed are more resistant to insecticides than their unfed siblings. We describe a simple model (ULVSIM) that incorporates physiologic changes in insecticide susceptibility and accounts for much of our field data. The model follows 30 cohorts over 30 days following insecticidal treatment. Multiple treatments or short-term residual activity can be evaluated. The model predicts that oviposition will follow a pattern of damped oscillations after an adulticidal treatment. The model gave a good fit to oviposition data obtained in 2 field trials of resmethrin for 7 to 9 days after treatment. It can be used to evaluate the effect of single and multiple treatments on the total female Culex population and on numbers of infected females surviving for different periods following an infective blood meal.
当对超低剂量（ULV）杀虫剂应用后的处理后反应进行了近一周的跟踪时，观察到产卵率出现衰减振荡，这可能是因为最近吸食过血液的雌性比未吸食过的同胞对杀虫剂更具抗性。我们描述了一个简单的模型（ULVSIM），该模型纳入了杀虫剂敏感性的生理变化，并解释了我们的许多现场数据。该模型在杀虫处理后的30天内跟踪30个队列。可以评估多次处理或短期残留活性。该模型预测，在进行成虫处理后，产卵将遵循衰减振荡模式。该模型与在灭虫菊酯的2次田间试验中处理后7至9天获得的产卵数据拟合良好。它可用于评估单次和多次处理对雌性库蚊总数以及感染性血餐后不同时期存活的感染雌性数量的影响。
