the effect of colchicine on myogenesis in vivo in rana pipiens and rhodnius prolixus (hemiptera).the effect of colchicine on myogenesis in vivo has been studied in the regenerating tadpole tail of the frog, rana pipiens, and in the abdominal molting muscles of a blood-sucking bug, rhodnius prolixus stål. colchicine is shown to disrupt microtubules in the differentiating muscle cells of both these organisms. the disruption of microtubules is correlated with a loss of longitudinal anisometry in the myoblasts and myotubes of the regeneration blastema in the tadpole tail. before colchicine trea ...19684177377

arthropod transmission of rabbit papillomatosis.the virus of rabbit papillomatosis, a neoplastic disease studied intensively in relation to cancer because of its tendency toward malignant transformation, has been successfully transmitted by aedes aegypti, rhodnius prolixus, and triatoma infestans from papillomas induced in cottontail rabbits, and by the first species mentioned, from papillomas induced in domestic rabbits. this was accomplished by interrupted feeding, feeding after an interval of several days from the infective meal, or by app ...195813549638

standardization of a continuous assay for glycosidases and its use for screening insect gut samples at individual and populational levels.glycoside hydrolases (ghs) are enzymes able to recognize and cleave glycosidic bonds. insect ghs play decisive roles in digestion, in plant-herbivore, and host-pathogen interactions. gh activity is normally measured by the detection of a release from the substrate of products as sugars units, colored, or fluorescent groups. in most cases, the conditions for product release and detection differ, resulting in discontinuous assays. the current protocols result in using large amounts of reaction mix ...028553236
demographic fitness of belminus ferroae (hemiptera: triatominae) on three different hosts under laboratory conditions.triatominae are widely recognised for their role as vectors of trypanosoma cruzi. one of the main biological characteristics of this subfamily is their obligate haematophagous condition. however, previous studies on belminus herreri and belminus ferroae suggested that cockroaches are their principal hosts in domiciles. due to this peculiar behaviour, the aim of this study was to analyse several demographic and reproductive parameters of b. ferroae fed on three different hosts (mice, cockroaches ...024141961
genetic basis of triatomine behavior: lessons from available insect genomes.triatomines have been important model organisms for behavioural research. diverse reports about triatomine host search, pheromone communication in the sexual, shelter and alarm contexts, daily cycles of activity, refuge choice and behavioural plasticity have been published in the last two decades. in recent times, a variety of molecular genetics techniques has allowed researchers to investigate elaborate and complex questions about the genetic bases of the physiology of insects. this, together w ...024473804
interaction of lipophorin with rhodnius prolixus oocytes: biochemical properties and the importance of blood feeding.lipophorin (lp) is the main haemolymphatic lipoprotein in insects and transports lipids between different organs. in adult females, lipophorin delivers lipids to growing oocytes. in this study, the interaction of this lipoprotein with the ovaries of rhodnius prolixus was characterised using an oocyte membrane preparation and purified radiolabelled lp (125i-lp). lp-specific binding to the oocyte membrane reached equilibrium after 40-60 min and when 125i-lp was incubated with increasing amounts of ...024037104
the origin and evolution of six miniature inverted-repeat transposable elements in bombyx mori and rhodnius prolixus.miniature inverted-repeat transposable elements (mites) are a specific group of nonautonomous dna transposons, and they are distributed in a wide range of hosts. however, the origin and evolutionary history of mites in eukaryotic genomes remain unclear. in this study, six mites were identified in the silkworm (bombyx mori). five elements are grouped into four known superfamilies of dna transposons, and one represents a novel class of mites. unexpectedly, six similar mites are also present in the ...024115603
neuropeptide action in insects and crustaceans.physiological processes are regulated by a diverse array of neuropeptides that coordinate organ systems. the neuropeptides, many of which act through g protein-coupled receptors, affect the levels of cyclic nucleotides (camp and cgmp) and ca(2+) in target tissues. in this perspective, their roles in molting, osmoregulation, metabolite utilization, and cardiovascular function are highlighted. in decapod crustaceans, inhibitory neuropeptides (molt-inhibiting hormone and crustacean hyperglycemic ho ...020550437
