Behavioral evidence of an ectoparasitic interaction between Triatoma pseudomaculata Corrêa e Espínola (Heteroptera: Reduviidae) and Periplaneta americana (L.) (Blattodea: Blattidae).

چکیده
The present work tested whether Triatoma pseudomaculata Corrêa & Espínola shows behavioral traits indicating that it is capable of feeding on arthropods. We consistently observed nymphs extending their proboscis in the direction of cockroaches and attempting to bite. Insects presented a preference for biting specific cockroach body parts. Our results suggest that arthropod hemolymph represents an alternative source of food that increases the survival of T. pseudomaculata individuals undergoing long starvation.

Biological aspects of crosses between Triatoma maculata (Erichson, 1848) and Triatoma pseudomaculata Corrêa & Espínola, 1964 (Hemiptera: Reduviidae).
Due to morphological similarities between Triatoma maculata and T. pseudomaculata, which comprise the "maculate complex", both had been regarded as the same species until 1964. Considering that the studies on triatomine hybridization permit hypotheses formulation concerning origin and divergence of species, enabling a quantitative analysis of taxonomic relationships between species, the present...

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 کاملGenetic Analysis of Periplaneta americana (Blattodea: Blattidae) in Central Texas Using the ITS1 Region
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 s...

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 ...

Triatoma pseudomaculata Corrêa and Espínola, 1964 and Triatoma juazeirensis Costa and Felix, 2007 ( = T. brasiliensis Neiva, 1911 [part]), are sylvatic vectors of Trypanosoma cruzi (Chagas, 1909), the causative agent of Chagas disease, in northeast Brazil-especially in the caatinga region. In an area of caatinga in the State of Bahia, we compared the wild and peridomestic habitats of these two ...
