“…In the current study, 69% (9 out of 13) of field-collected bed bug populations evolved with high RR 90 (> 91.9). Deltamethrin resistance in bed bug field populations from the U.S. was mentioned in previous studies [ 26 , 55 ]. Cotton and Indy populations exhibited RR 50 for deltamethrin less than 2.0, but the mortality was only 73% and 67%, respectively.…”

Insecticide resistance is one of the factors contributing to the resurgence of the common bed bug, Cimex lectularius L. This study aimed to profile the resistance levels of field-collected C. lectularius populations to two neonicotinoids and one pyrethroid insecticide and the performance of selected insecticide sprays and an inorganic dust. The susceptibility of 13 field-collected C. lectularius populations from the United States to acetamiprid, imidacloprid, and deltamethrin was assessed by topical application using a discriminating dose (10 × LD90 of the respective chemical against a laboratory strain). The RR50 based on KT50 values for acetamiprid and imidacloprid ranged from 1.0–4.7 except for the Linden 2019 population which had RR50 of ≥ 76.9. Seven populations had RR50 values of > 160 for deltamethrin. The performance of three insecticide mixture sprays and an inorganic dust were evaluated against three C. lectularius field populations. The performance ratio of Transport GHP (acetamiprid + bifenthrin), Temprid SC (imidacloprid + β-cyfluthrin), and Tandem (thiamethoxam + λ-cyhalothrin) based on LC90 were 900–2017, 55–129, and 100–196, respectively. Five minute exposure to CimeXa (92.1% amorphous silica) caused > 95% mortality to all populations at 72 h post-treatment.

“…The presence of super-kdr mutations strongly suggests that the C. hemipterus population found in Korea is highly resistant to pyrethroids. Considering that the pyrethroid resistance level in C. lectularius populations in Korea has already reached a near-saturation level and increased pyrethroid resistance has been also observed worldwide in the 2 Cimex species (Lewis et al 2020, 2022), caution should be exercised when establishing a control strategy. In addition, since the climbing capacity of C. hemipterus is known to be far superior to that of C. lectularius (Kim et al 2017), the use of standard C. lectularius traps may not work against C. hemipterus , and thus a more sophisticated control strategy is required.…”

With the increase in international travel and trade, in conjunction with the development of insecticide resistance, infestations of Cimex lectularius (L.) and Cimex hemipterus (F.) (Hemiptera: Cimicidae) have resurged globally in the last 2 decades. Recently, it was reported that C. hemipterus was also found in temperate regions, indicating the possibility of its expansion outside tropical regions. Cimex hemipterus has not been officially recorded in Korea since its initial description in 1934. Here, we report the first recent case of C. hemipterus in Korea based on morphological and molecular identification. Partial sequencing of the voltage-sensitive sodium channel gene revealed super-kdr mutations (M918I and L1014F) that are associated with pyrethroid resistance. This case report serves as a warning to intensify the bed bug surveillance system in Korea regarding the presence of C. hemipterus and to prepare effective alternative insecticides for pyrethroids.

“…In addition, the usage of over-the-counter products for home treatment may lead to the increase in bed bugs resistance. A study conducted in the United States discovered that the long-term use of pyrethroid insecticides causes an increase in the kdr mutations in the C. lectularius population, which plays a role in insecticide resistance [56]. Similarly, a high prevalence of pyrethroid resistance associated with kdr mutations was also observed in the tropical bed bug, C. hemipterus [57,58].…”

The resurgence of bed bugs is a global phenomenon, but until now reports on bed bug infestations in Indonesia are rare. The success of bed bug control is affected by people’s knowledge and awareness. Stigma against bed bugs in Indonesia discourages the public from reporting infestations and therefore knowledge of their impact on public health is scarce. Herein, this study investigates the public’s perception, attitudes, and knowledge on bed bug-related issues in several major cities in Indonesia through an online survey. Despite low case reports, three in five respondents (n = 600) have encountered bed bugs at least once; mostly in their homes (74.1%). Approximately half of the respondents correctly identified bed bugs, whereas mites were often misidentified for bed bugs (26.3%). Bite marks were not a useful indicator for detecting bed bugs. We found age, gender, and level of education affects the public’s perception toward various bed bug-related issues. Regarding bed bug treatment, above 50% respondents are unaware of the availability of bed bug-specific insecticidal products and are unwilling to pay pest management professionals to control infestation. This study provides the first overview of the public’s awareness and perception of bed bug infestations in some major cities of Indonesia, which can be useful for designing public health policies for bed bug management. The reported data represents the perspectives of online users, most likely from metropolitan regions. A bigger monitoring program encompassing pest professionals and hospitality businesses would give a more thorough overview of the bed bug impact in Indonesia.
