DescriptionGlobal resurgence of bed bugs, Cimex lectularius L. (Hemiptera: Cimicidae), due to increasing global travel, trade and resistance to different types of insecticides, is a very important concern today as it causes socioeconomic burden, mental stress and public health concerns. Insecticide resistance is considered as one of the key factors for the worldwide resurgence of bed bugs. Two studies were done to identify the resistance levels of bed bugs collected from different locations in New Jersey and Indiana and to understand the effect of moisture on the efficacy of insecticides against bed bugs. In the first study, I evaluated the bed bug resistance to commonly used insecticides Phantom SC (chlorfenapyr), Suspend SC (deltamethrin) and Transport GHP (acetamiprid + bifenthrin) using a vial assay and Transport GHP (acetamiprid + bifenthrin), Temprid SC (imidacloprid + β-cyfluthrin), and Tandem (λ-cyhalothrin + thiamethoxam) using a petri dish assay. Low to high levels of resistance were observed among the different strains of bed bugs. Resistance ratios of various strains based on LC50 were Transport GHP: 92-1,682, Temprid SC: 18-144, and Tandem: 179-1,226. In the second study, I evaluated the effect of moisture on the efficacy of Cimexa (92.1% amorphous silica gel), Alpine (0.25% dinotefuran, 95% diatomaceous earth) and Tempo (1% cyfluthrin) against bed bugs. Moisture was created by two methods: 1. applying steam to insecticide dust treated panels and 2. aging the insecticide treated panels in chambers with various relative humidity (RH). Results show that exposure to moisture significantly reduced the efficacy of all tested insecticide dusts. The efficacy of the three insecticides was Cimexa > Alpine > Tempo. These results show that moisture needs be considered when applying insecticide dusts for controlling bed bug infestations.
