the triatomines of northern peru, with emphasis on the ecology and infection by trypanosomes of rhodnius ecuadoriensis (triatominae).information on the distribution and synanthropic behaviour of triatomines is essential for chagas disease vector control. this work summarises such information from northern peru, and presents new data on rhodnius ecuadoriensis - an important local vector infesting 10-35% of dwellings in some zones. three species are strongly synanthropic and may be suitable targets for chemical control of domestic/peridomestic bug populations. panstrongylus herreri, the main domestic vector in the area, is prob ...200212016438
the development of panstrongylus herreri under fluctuating environmental conditions.panstrongylus herreri is a main chagas disease vector, and its success as a vector stems from its ability to establish domiciliated colonies; we aimed to explore its biology and reproduction.201728327814
taxonomic status of panstrongylus herreri wygodzinsky, 1948 and the number of chagas disease vectors. 201728700072
comparative proteomic analysis of the saliva of the rhodnius prolixus, triatoma lecticularia and panstrongylus herreri triatomines reveals a high interespecific functional biodiversity.triatomines are hematophagous arthropods that transmit trypanosoma cruzi and trypanosoma rangeli. feeding behavior and pathogen transmission is known to vary between the different species, and this characteristic is directly or indirectly dependent on the bioactive molecules of the saliva that facilitate the vector-host-parasite interaction. here, we identify, characterize and compare the sialoproteomic (from the greek sialo: saliva) repertoire of important species of the main triatomine genera ...201626940473
biomorphological alterations induced by an anti-juvenile hormonal compound, 2-(2-ethoxyethoxy)ethyl furfuryl ether, on three species of triatominae larvae (hemiptera, reduviidae).applied topically to larvae of rhodnius prolixus stal, triatoma infestans (klug) and panstrongylus herreri wygodzinsky, vectors of trypanosoma cruzi, the causative agent of chagas' disease, a synthetic, furan-containing anti-juvenile hormonal compound, 2-(2-ethoxyethoxy)ethyl furfuryl ether induced a variety of biomorphological alterations, including precocious metamorphosis into small adultoids with adult abdominal cuticle, ocelli, as well as rudimentary adultoid wings. some adultoids died duri ...19979332589
beauveria bassiana (hyphomycetes) as a possible agent for biological control of chagas disease vectors.beauveria bassiana (balsamo) vuillemin (isolate cg306) was tested on 3rd instars of 9 triatoma spp., 4 rhodnius spp., 2 panstrongylus spp. and dipetalogaster maxima (uhler) at 25 degrees c and 50% rh. quantitative sporulation of the fungus on cadavers was studied at 25 degrees c and 97% rh. mortality, estimates of survival time, and conidial production on cadavers differed significantly among the genera and species tested. panstrongylus herreri wygodzinsky, dipetalogaster maxima, triatoma pictur ...19989835689
pathogenicity of evlachovaea sp (hyphomycetes), a new species isolated from triatoma sordida, in chagas' disease vectors.evlachovaea sp was tested on nymphs of 5 triatoma spp 5 rhodnius spp, panstrongylus herreri and dipetalogaster maximus at 25 degrees c, 75% humidity and humidity >98%. most species showed susceptibility to fungal infection at high humidity. mortality was reduced at 75% humidity. fungal development was observed on 69.5% of cadavers.200615094910
