The global population of bed bugs Cimex lectularius and Cimex hemipterus , family Cimicidae has undergone a significant resurgence since the late s. This is likely due to an increase in global travel, trade, and the number of insecticide-resistant bed bugs.

Bedbugs are blood feeding ectoparasites of humans and several domesticated animals. There are scarcity of information about the bed bugs population throughout Iran and only very limited and local studies are available. The aim of this study is to assess the phylogenetic relationships and nucleotide diversity using partial sequences of cytochrome oxidase I gene COI among the populations of tropical bed bugs inhabiting Iran. The bedbugs were collected from cities located in different geographical regions of Iran. DNA sequencing analysis showed that the all C. Subsequently, the results were compared with the database in gene bank which revealed close similarity and sequence homology with other C. In conclusion, this study has demonstrated the ability of the COI gene to differentiate between the C.

Cite This Article. A Adult bedbug Cimex lectularius ; B mattress infested with bedbugs an adult, eggs, and dejecta ; C dermatitis caused by bedbug bites. To the Editor: Bedbugs Cimex lectularius are hematophagous insects. Adults are 4—6 mm long, flattened, oval and wingless, and brown to brownish-red Figure , panel A 1. They may feed in the wild on birds or bats 2 , but they are mainly associated with human dwellings and can be found on furniture and clothing 3. Because bedbugs are nocturnal and feed painlessly only in the dark, while humans sleep, initial bedbug proliferation usually goes unnoticed until several weeks later when the patient discovers a pruritic cutaneous eruption of unknown origin 4. Decades ago, bedbugs were frequently found worldwide, but reports of cases in industrialized countries have progressively declined, probably the result of improved living conditions 3.

Cryptozona siamensis , one of the most widespread land snails, is native to Thailand, and plays a key role as an agricultural pest and intermediate host for Angiostrongylus spp. However, its genetic diversity and population structure has not yet been investigated, and are poorly understood. Therefore, a genetic analysis of the C. Cryptozona siamensis randomly collected from 17 locations in four populations across Thailand, between May and July Fifty-eight snails were used to examine the phylogeny, genetic diversity, and genetic structure.

 - Осталось девять минут. Сьюзан, не слушая его, повернулась к Соши. - Сколько там этих сироток? - спросила. Соши развела руками. Она села за терминал Джаббы и перепечатала все группы, а закончив, подбежала к Сьюзан. Все посмотрели на экран.

Стратмор заговорил тише, явно желая ее успокоить: - Я бы не назвал этого парня панком. Но Сьюзан его не слушала. Она была убеждена, что должно найтись какое-то другое объяснение. Сбой. Вирус. Все, что угодно, только не шифр, не поддающийся взлому. Стратмор сурово посмотрел на .

 Может. - Может. - Мы должны позвонить ему и проверить. - Мидж, он же заместитель директора, - застонал Бринкерхофф.  - Я уверен, у него все под контролем. Давай не… - Перестань, Чед, не будь ребенком. Мы выполняем свою работу.

Я тебя разбудил. Она улыбнулась и поудобнее устроилась в постели. - Ты мне только что приснился.
