We tested a threshold-based bed bug ( L.) management approach with the goal of achieving elimination with minimal or no insecticide application. Thirty-two bed bug infested apartments were identified. These apartments were divided into four treatment groups based on apartment size and initial bed bug count, obtained through a combination of visual inspection and bed bug monitors: I- Non-chemical only in apartments with 1-12 bed bug count, II- Chemical control only in apartments with 1-12 bed bug count, III- Non-chemical and chemical control in apartments with >12 bed bug count, and IV- Chemical control only in apartments with ≥11 bed bug count. All apartments were monitored or treated once every two weeks for a maximum of 28 wk. Treatment I eliminated bed bugs in a similar amount of time to treatment II. Time to eliminate bed bugs was similar between treatment III and IV but required significantly less insecticide spray in treatment III than that in treatment IV. A threshold-based management approach (non-chemical only or non-chemical and chemical) can eliminate bed bugs in a similar amount of time, using little to no pesticide compared to a chemical only approach.
我们测试了一种基于阈值的臭虫（床虱）管理方法，目标是以最少或不使用杀虫剂来实现根除。共识别出32个有臭虫侵扰的公寓。这些公寓根据公寓面积和通过目视检查与臭虫监测器相结合得出的初始臭虫数量分为四个处理组：I组——臭虫数量为1至12只的公寓仅采用非化学方法，II组——臭虫数量为1至12只的公寓仅采用化学防治，III组——臭虫数量超过12只的公寓采用非化学和化学防治，IV组——臭虫数量≥11只的公寓仅采用化学防治。所有公寓每两周监测或处理一次，最长持续28周。I组消灭臭虫的时间与II组相近。III组和IV组消灭臭虫的时间相近，但III组所需的杀虫剂喷洒量明显少于IV组。与仅采用化学方法相比，基于阈值的管理方法（仅非化学方法或非化学与化学方法结合）能够在相近的时间内消灭臭虫，且使用很少或不使用杀虫剂。
