| semiochemicals of the common bed bug, cimex lectularius l. (hemiptera: cimicidae), and their potential for use in monitoring and control. | the recent resurgence of the common bed bug, cimex lectularius l., has driven an increase in research into the biology and behaviour of this pest. current control is reliant on the application of insecticides, but, owing to the development of insecticide resistance, there is a need for new tools and techniques. semiochemicals (behaviour- and physiology-modifying chemicals) could be exploited for management of bed bugs. the aim of this review was to evaluate studies undertaken in bed bug chemical ... | 2011 | 20859928 |
| metabolic resistance in bed bugs. | blood-feeding insects have evolved resistance to various insecticides (organochlorines, pyrethroids, carbamates, etc.) through gene mutations and increased metabolism. bed bugs (cimex lectularius) are hematophagous ectoparasites that are poised to become one of the major pests in households throughout the united states. currently, c. lectularius has attained a high global impact status due to its sudden and rampant resurgence. resistance to pesticides is one factor implicated in this phenomenon. ... | 2011 | 26467498 |
| Psychological Effects of Bed Bug Attacks (Cimex lectularius L.). | In some individuals, psychological sequelae resulting from bed bug biting events include nightmares, flashbacks, hypervigilance (to keep the bugs away), insomnia, anxiety, avoidance behaviors, and personal dysfunction. These symptoms are suggestive of posttraumatic stress disorder (PTSD). | 2012 | 22195533 |
| a preliminary evaluation of the potential of beauveria bassiana for bed bug control. | residual biopesticide treatments of beauveria bassiana were tested against the bed bug cimex lectularius. an oil formulation of conidia was applied to different substrates. bed bugs were exposed for 1 h, transferred to an unsprayed environment and monitored for mortality. separate bioassays evaluated the effect of bed bug strain, sex, life stage, and exposure substrate on mortality. rapid mortality was observed in all bioassays, with bed bugs exposed to treated jersey knit cotton dying most rapi ... | 2012 | 22555012 |
| increasing use of pyrethroids in canadian households: should we be concerned? | pyrethroids are a class of plant-derived insecticides and their man-made analogues that are increasingly applied in canada as first choice for pest control in many agricultural and residential settings. their popularity is partly due to their alleged safety compared to the older organochlorine and organophosphate insecticides. application of pyrethroids is expanding because of recent increases in the level of pest infestations--such as bed bugs--and the decreased susceptibility of target species ... | 2012 | 23618016 |
| bed bugs and public health: new approaches for an old scourge. | to share four canadian cities' experiences with bed bug infestations and to explore public health roles in managing them. | 2012 | 23618015 |
| rna interference of nadph-cytochrome p450 reductase results in reduced insecticide resistance in the bed bug, cimex lectularius. | nadph-cytochrome p450 reductase (cpr) plays a central role in cytochrome p450 action. the genes coding for p450s are not yet fully identified in the bed bug, cimex lectularius. hence, we decided to clone cdna and knockdown the expression of the gene coding for cpr which is suggested to be required for the function of all p450s to determine whether or not p450s are involved in resistance of bed bugs to insecticides. | 2012 | 22347424 |

| dermatologic infestations. | head lice are transmitted by head to head contact. optimal therapy includes malathion lotion 0.5% repeated in one week left on for 30 minutes to 8 hours. spinosad topical suspension 0.9% repeated in one week left on for 10 minutes is another option. scabies is transmitted mainly by direct contact but also via heavily infested fomites due to crusted scabies. permethrin 5% cream to the body repeated in four days is often sufficient; however, scalp treatment with malathion lotion 0.5% is helpful in ... | 2012 | 22250620 |
| rna-seq and molecular docking reveal multi-level pesticide resistance in the bed bug. | bed bugs (cimex lectularius) are hematophagous nocturnal parasites of humans that have attained high impact status due to their worldwide resurgence. the sudden and rampant resurgence of c. lectularius has been attributed to numerous factors including frequent international travel, narrower pest management practices, and insecticide resistance. | 2012 | 22226239 |
| artificial infection of the bed bug with rickettsia parkeri. | although a variety of disease agents have been reported from bed bugs, the mechanical and biological disease transmission potential of bed bugs remains unelucidated. in this study we assayed survivability of the mildly pathogenic spotted fever group rickettsia, rickettsia parkeri, in bed bugs after feeding on r. parkeri-infected chicken blood. two groups of 15 adult bed bugs each were fed on infected or noninfected blood, and two groups of fourth-instar bed bugs also were fed on either infected ... | 2012 | 22897053 |
| genetic analysis of bed bug populations reveals small propagule size within individual infestations but high genetic diversity across infestations from the eastern united states. | bed bugs (cimex lectularius l.) are a resurgent pest worldwide and infestations within the united states are increasing at a rapid rate. because of the physical and psychological discomfort inflicted by their blood feeding habits, and allergies and secondary infections associated with bites, bed bugs are recognized as a significant public health problem. although bed bug infestations are spreading and becoming more prevalent, we have a poor understanding of their dispersal patterns and sources o ... | 2012 | 22897047 |
| molecular markers reveal infestation dynamics of the bed bug (hemiptera: cimicidae) within apartment buildings. | the bed bug, cimex lectularius l. (hemiptera: cimicidae), has experienced an extraordinary global resurgence in recent years, the reasons for which remain poorly understood. once considered a pest of lower socioeconomic classes, bed bugs are now found extensively across all residential settings, with widespread infestations established in multiapartment buildings. within such buildings, understanding the population genetic structure and patterns of dispersal may prove critical to the development ... | 2012 | 22679860 |

| susceptibility of cimex lectularius (hemiptera: cimicidae) to pyrethroid insecticides and to insecticidal dusts with or without pyrethroid insecticides. | relative increases of bed bug, cimex lectularius l., populations are probably due in large measure to their resistance to pyrethroids, which have been used extensively against urban pests. a connecticut population of bed bugs was assessed for sensitivity to pyrethroids and exposed to commonly-used commercial insecticides applied to various substrates on which the residues were allowed to age for 0-24 wk. type i and type ii pyrethroids differed in toxicity when applied at a high dosage (1 microg) ... | 2012 | 23156178 |
| human travel and traveling bedbugs. | a dramatic increase of reported bedbug (cimex lectularius and cimex hemipterus) infestations has been observed worldwide over the past decade. bedbug infestations have also been detected across a wide range of travel accommodations, regardless of their comfort and hygiene levels. travelers are increasingly exposed to the risks of bedbug bites, infestation of personal belongings, and subsequent contamination of newly visited accommodations and their homes. | 2012 | 23379708 |
| efficacy of commercially available ultrasonic pest repellent devices to affect behavior of bed bugs (hemiptera: cimicidae). | little is known about the potential for acoustic communication in bed bugs, cimex lectularius l. (hemiptera: cimicidae), or the use of sound as cues in host location, although many hemipterans are known to communicate with sound. most behavioral research has focused on bed bug pheromones that are used in aggregation and as alarm signals. we investigated the influence of sound as a deterrent and as an attractant, either of which could ultimately be used to monitor and control bed bugs. female bed ... | 2012 | 23356076 |
| otitis from the common bedbug. | there is a resurgence of interest in the biology and clinical disease associated with cimex lectularius, as the common bed bug is becoming more prevalent in well-developed countries. a patient presented with complaints of right ear irritation for several days' duration. a foreign body was lavaged from the ear canal, which proved to be an engorged nymphal form of cimex lectularius. the parasite had apparently obtained a blood feed from the tympanic membrane. the resolution of the illness was unre ... | 2012 | 23277805 |
| carbon dioxide fumigation for controlling bed bugs. | we investigated the potential of carbon dioxide (co2) fumigation as a method for controlling bed bugs, cimex lectularius l. the effect of bed bug developmental stage, temperature, and co2 concentration on the minimum time to kill 100% of bed bugs was determined. the minimum co2 concentration lethal to all bed bug stages was approximately 30% with 24 h exposure time at 25 degrees c. the minimum fumigation time required to kill 100% of eggs using 100% co2 at 20, 25, and 30 degrees c were 3, 7, and ... | 2012 | 23025189 |

| ineffectiveness of over-the-counter total-release foggers against the bed bug (heteroptera: cimicidae). | field-collected bed bugs (cimex lectularius l.) showed little, if any, adverse effects after 2-h direct exposure to the aerosolized pyrethroid(s) from three over-the-counter total-release foggers ('bug bombs' or 'foggers'); hotshot bedbug and flea fogger, spectracide bug stop indoor fogger, and eliminator indoor fogger. one field-collected population, epm, was an exception in that there was significant mortality at 5-7 d when bugs out in the open had been exposed to the spectracide fogger; morta ... | 2012 | 22812136 |
| bed bug (cimex lectularius l.) population composition as determined by baited traps. | two established field populations of bed bugs were sampled using host-mimicking traps baited with a combination of co2, heat and a synthetic kairomone. the proportion of first instar nymphs (between 52% and 78% of all captured insects) was significantly higher than reported in previous studies, which had employed different sampling methods. the proportion of adults was correspondingly much lower than previously reported, between 5% and 7% of total capture. as many as 120 bed bugs were captured i ... | 2012 | 26466537 |
| comparison of three bed bug management strategies in a low-income apartment building. | bed bug (cimex lectularius l.) infestations are currently controlled by a variety of non-chemical and chemical methods. there have been few studies on the comparative effectiveness of these control techniques. we evaluated three bed bug management strategies in an apartment building: (1) non-chemical methods only (n = 9); (2) insecticides only (n = 6); and (3) integrated pest management including both non-chemical methods and insecticides (n = 9). the apartments were one-bedroom units occupied b ... | 2012 | 26466533 |
| smelling your way to food: can bed bugs use our odour? | the resurgence in developed countries of the common bed bug, cimex lectularius, has led to a search for new sustainable methods to monitor and control this human ectoparasite. because of increased resistance to insecticides, traps baited with attractive cues are considered a promising method to be developed into efficient monitoring tools for bed bugs. despite their potential as attractants, only a few studies have investigated the odorant cues implicated in the attraction of bed bugs to human h ... | 2012 | 22279069 |
| bed bugs in healthcare settings. | infestations caused by bed bugs have resurfaced during the past decade across all continents. even though bed bugs primarily cause skin manifestations in humans, a major stigma is placed upon people or institutions found to carry them. it is important for healthcare facilities to be prepared for this pest by implementing policies, carefully selecting materials used for hospital furniture, and educating providers on early identification and control. | 2012 | 23041813 |
| bed bugs: they are back! the role of the school nurse in bed bug management. | recently there has been a resurgence of bed bugs in all facets of our society. bed bugs have even been found in schools, causing unnecessary exclusion of students and unfounded hysteria. school nurses are again called upon to be front-line sources of information to quell the hysteria and confusion related to this unsavory condition. by arming themselves with the best evidence regarding proper identification of bed bugs and their bites and information about integrated prevention measures to contr ... | 2012 | 23008871 |

| comparison of multiple steam treatment durations for control of bed bugs (cimex lectularius l.). | the factors contributing to the current resurgence of bed bug cimex lectularius l. populations across the united states and elsewhere include, among others, the development of resistance to chemical insecticides and population management practices. this has led to the development and attempted refinement of many non-chemical control methods that contribute to an ipm approach to solving the current bed bug population density increase in urban dwellings. one such approach is the use of heat in the ... | 2013 | 23371878 |
| repellency of selected chemicals against the bed bug (hemiptera: cimicidae). | in recent years, the common bed bug, cimex lectularius l. (hemiptera: cimicidae), became a major public health concern in urban communities. bed bugs are notoriously difficult to control, and their bites are not tolerated by most people. the public has an urgent need for materials and methods to reduce bed bug introduction and bites during work, travel, or sleep. a repellent product will help achieve these goals by discouraging and preventing bed bugs from moving to a protected area. we evaluate ... | 2013 | 24498754 |
| two different lineages of bedbug (cimex lectularius) reflected in host specificity. | co-speciation between host-parasite species is generally thought to result in mirror-image congruent phylogenies. for the last several centuries, many bat species have been turning synanthropic, especially those that are hosted by bedbugs in europe. there is evidence of only limited gene flow from the population of people to the population of bats. this study was focused on comparison of survival, development, and the reproduction rate based on cross-feeding experiments. in our research, we used ... | 2013 | 23982311 |
