Straw itch mites, Pyemotes tritici, will bite people as they come into contact with infested straw, hay, grasses, oats, or peas. The Environmental Protection Agency (EPA), the Centers for Disease Control and Prevention (CDC), and the United States Department of Agriculture (USDA) all consider bed bugs a public health pest. Figure E: Higher magnification of the specimen in Figure D, showing a close-up of the typical hemipteran piercing-sucking mouthparts (arrow). Reduviid bugs (colloquially known as kissing bugs or assassin bugs) transmit the trypanosome protozoan that causes Chagas disease in Central and South America (see p. 651). Cimex Lectularius or Bed Bugs : Vector of Infectious Agents and Pathogenic Role The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. wide, dorsoventrally flattened, oval-shaped, and light brown to reddish-brown. Finally, in 1897, the exact phrase appears in a usage book that explains what a boy in New England would say to a companion as they part for the evening—“Goodnight, sleep tight, don’t let the bedbugs bite.”10 The “sleep tight” part of the rhyme may have originated from beds supported by ropes tied in a weave like a hammock, a predecessor to the box-spring, used during the 18th and early 19th centuries. Though generally regarded as a nuisance or irritant pest, the common bed bug (Cimex lectularius) is known to be capable of harboring more than 40 human disease-causing pathogens. The good news is that bed bugs do not transmit disease. Cimex lectularius, the common bed bug, is the most widespread and best known species as it prefers to feed on human blood. Adults and all nymphal stages of Cimex spp. It is most common in the south-central United States. We report on a 37-year-old man who developed a bullous reaction with fever and general malaise due to bites of the common bedbug, Cimex lectularius. However, insecticide-resistance has developed and bedbugs are becoming more abundant. Scabies, which is caused by a mite, is common worldwide and transmitted from person to person. The tip of the labium extends to the level of the first pair of legs. The piercing-sucking mouthparts (stylet) penetrate through the skin of the host and inject saliva with anticoagulants and painkillers that aid in a painless bite.14 Bed bugs feed about every 3–7 days and engorge with blood in about 10–15 min. Fortunately, bullous and systemic reactions are rare. Data on the increase in the number of bed bugs (Cimex lectularius) at the end of the XX century and the beginning of the XXI century in highly developed countries of Europe, America and Australia and the cases of this phenomenon are given. Bed bug bites are caused primarily by two species of insects: Cimex lectularius (the common bed bug) and Cimex hemipterus, found primarily in the tropics. Cimex lectularius is a species of Cimicidae (bed bugs). Bed Bugs (Cimex Lectularius) – FAQ; Bed Bugs (Cimex Lectularius) – Parent Information; Bites; Biting Incident- Parent Information Sheet; Chicken Pox (Varicella) Common Cold- Upper Respiratory Infection; Communicable Disease List; Communicable Diseases: Prevention and Control; Communication Protocol for Contagious Diseases; Cytomegalovirus (CMV) Cimex lectularius, have recently undergone explosive growth. The adults do not bite. The classic presentation involves three bites in linear array, also known as “breakfast, lunch, and dinner” pattern. Note the reduced forewings (arrow).

The brown recluse spider, Loxosceles reclusa, is perhaps the most important member of the group, although other violin spiders producing necrotic lesions also occur in the United States and elsewhere. There has been a tremendous increase in the number of reported bed bug infestations over the past decade.19 Bed bugs have occasionally been found that are naturally infected with disease organisms such as those causing anthrax, plague, and typhus. Chicken bugs are not known to transmit any avian pathogens. Simple antipruritics are generally the only treatment needed for biting midge bites. Competent pest control operators (exterminators) are often helpful in finding and eliminating bird nests or rat burrows in and around the home.

The life cycle of the bedbug consists of egg, five instars of nymphs, and adults. R.C. Cimex is not thought to be a vector although recent studies have shown that it can transmit Trypanosoma cruzi, the pathogen for Chagas disease in mice. Paralysis, stupor, and convulsions may occur in severe cases, with an occasional fatality. Cimex lectularius is cosmopolitan in distribution; C. hemipterus is distributed in the tropics and sub-tropics, Although bed bugs have been found naturally-infected with blood-borne pathogens, they are not effective vectors of disease. The flea plays an important role in the spread of the plague by transmitting the organism from rats to humans.

Book lice (Liposcelis bostrichophila) have been reported as major indoor pests in Japan, infesting up to 90% of dust samples with a preference for tatami mats; a 26 kDa IgE-binding protein without cross-reactivity to previously described allergens was identified and named Lip b 1 (Fukutomi et al., 2012). The spread of these diseases is rapid and therefore warrants immediate attention in school health and public health policy.
