Genetic Analysis of Periplaneta americana (Blattodea: Blattidae) in Central Texas Using the ITS1 Region
نویسندگان
چکیده
American cockroaches, Periplaneta americana (Blattodea: Blattidae) (L.), are common pests of urban environments. Analyzing spatial distribution of P. americana populations in an artificial, outdoor environment provided insight of gene flow among populations collected in central Texas. This information provides a better understanding of how and if populations were segregated, or if there was a single unified population. Populations can be genetically differentiated through determining variation of specific gene regions within populations. This study revealed a ubiquitous distribution of cockroach populations, and their ability to indiscriminately inhabit areas within an urban environment. Overall, cockroaches were identified from a large interbreeding population with no discernable relationship between genetic variation of P. americana and spatial distribution.

Identifying cockroach (Order: Blattodea) populations is important to understanding the ability of surrogate species indirectly affecting humans by their ability to vector disease-causing organisms including bacteria. These interactions may have potentially deleterious health consequences on animal and/or human populations. In this study, American cockroaches, Periplaneta americana were sampled ...

در این تحقیق به بررسی اثر تاکیکینین بر روی فعالیت آلفا آمیلاز، پروتئاز و لیپاز در معده میانی سوسری امریکایی (L.) Periplaneta americana پرداخته شد. فعالیت ایمنوهیستوشیمیایی سلول‌های معده میانی (بخش های جلویی، میانی و عقبی) که تاکیکینین ترشح می‌کردند مورد تایید قرار گرفت. چهار هفته گرسنگی، تعداد سلول هایی را که عکس العمل ایمنوهیستوشیمیایی مقابل آنتی‌بادی تاکیکینین داشتند (Tachykinin-ir cel...
متن کاملIndividual Thigmotactic Preference Affects the Fleeing Behavior of the American Cockroach (Blattodea: Blattidae)
Positive thigmotactic behavior is associated with the ability to hide from predators and is important to explain aggregation and collective patterns in various animals. For example, this behavior has been observed in woodlice, domiciliary cockroaches, ants, and fish. Lately, research on different species is focused on the importance of animal personality for ecological and evolutionary processe...

The effect of a neuropeptide, the tachykinin on α-amylase, protease and lipase activities in the midgut of American cockroach, Periplaneta americana (Linnaeus) is evaluated . Immunohistochemical reactivities against tachykinin (tachykininir) were detected in the midgut. Tachykinin-ir cells in three regions (anterior, median and posterior) of the midgut were counted in normally fed, starved for ...
متن کاملEffect of melatonin on the release of prothoracicotropic hormone from the brain of Periplaneta americana (Blattodea: Blattidae)
The occurrence of melatonin is known in nearly all organisms, hut nothing is known exactly about its function outside of vertebrates. Long-term perifusions as well as short-term batch incubations of brains and moulting glands of the cockroach Peri planeta americana were used to identify the effect of melatonin on the release of prothoracicotropic hormone, a glandotropic neuro peptide in the b...
