| observations on the feeding and defecation patterns of three triatomine species (hemiptera: reduviidae). | a comparative laboratory study of feeding and defecation behavior of three species of tritomines (rhodnius prolixus, triatoma infestans and t. dimidiata) indicated evident differences among the species and among the different stages of same species. time required for a full blood meal was related to the size of the specimen. insects required an average of 11-28 min for engorgement although some finished within 10 min. t. dimidata frequently interrupted the act of feeding, a probable explanation ... | 1977 | 16468 |
| comparison of infectivity of trypanosoma cruzi blood stream trypomastigotes and metacyclic trypomastigotes from rhodnius prolixus. | four strains of trypanosoma cruzi (y, bg, m and peru) retain their ability to infect rhodnius prolixus and to produce virulent infections in mice for from 12 to 39 years. about 60 or more metacyclic trypomastigotes were consistently lethal to mice. the mean number of metacyclics per bug ranged from 1.2 to 17.3 x 10(3). comparative studies of virulence of metacyclics and blood trypomastigotes showed the blood forms to be slightly more virulent. the route of injection was shown to be more signific ... | 1977 | 16470 |

| [spontaneous infection of marmoset-monkeys (sanguinus oedipus) with a trypanosoma cruzi-like-strain, springer 1975. isolation and identification (author's transl)]. | a trypanosoma cruzi-like strain was isolated from marmoset monkeys originating from columbia. the frequency of affected monkeys was up to 32.7%. the parasite density was 10-40 trypomastigote forms per mililiter. monkeys, rats, mice and other small rodentia were found to be susceptible. clinical symptoms or histopathological findings could not be acertained with these trypanosomes even after a 2 1/2 year observation period. the strain behaved as an apathogen in experimental animals. the parasitae ... | 1977 | 416623 |

| excretion of alkaloids by malpighian tubules of insects. | nicotine is transported at high rates by malpighian tubules of larvae of manduca sexta, pieris brassicae and rhodnius prolixus and the transport persists in the absence of alkaloid from the diet. in the fluid-secreting portion of rhodnius tubules this transport is not coupled to ion transport, nor is it dependent on the physiological state of the animal. the transport, which can occur against a steep electrochemical gradient, shows saturation kinetics with a maximal rate of 700 pmol. min-1 per t ... | 1976 | 932618 |
| the inheritance of radiation induced semi-sterility in rhodnius prolixus. | eggs from crosses of 40 adult male r. prolixus irradiated with 6k rad gamma-rays with normal females had a mean fertility of 23.9%, only 2 crosses being completely sterile. the 86 f1 progeny of both sexes, when outcrossed with normal mates, had a mean egg fertility of 12.6;, and 43 of these matings were completely sterile. twenty-eight "f2" bugs reared from f1 x normal crosses were mated with normal partners and had a mean fertility of 44.6%, 6 of them being fully fertile, a reversal towards nor ... | 1976 | 793795 |

| distribution of lipid in the lamellate endocuticle of rhodnius prolixus (hemiptera). | the lamellate appearance of the cuticle in the abdomen of the rhodnius larva conforms to the conception of bouligand in being an optical artifact which results from the spiral arrangement of successive layers of oriented fibrils. but superimposed on this structure is an actual lamination of bound lipid with the same spacing. the relation of the lipid layers to the optical lamination changes with the aspect from which the system is viewed. there must therefore be a cyclical secretion of lipid by ... | 1975 | 1107337 |

| insect peripheral nerves: accessibility of neurohaemal regions to lanthanum. | during incubation in vivo, exogenously applied ionic lanthanum comes to surround the numerous neurosecretory terminals which are found lying within or immediately beneath the acellular neural lamella ensheathing the nerves from fifth instar and adult specimens of rhodnius prolixus. the lanthanum does not penetrate beyond the cellular perineurium, which completely surrounds the non-neurosecretory axons in these nerves and constitutes a form of 'blood-brain barrier'. in some cases, however, lantha ... | 1975 | 1141392 |

| ultrastructure of neurosecretory cells in the pars intercerebralis of rhodnius prolixus (hemiptera). | six neuron types are distinguished in the pars intercerebralis of the starved fifth instar of rhodnius prolixus. all neuron types contain electron dense secretory granules derived from golgi complexes which are of characteristic size and morphology in each type. the neuron types are not thought to represent stages in a secretory cycle. the variety of neuron types described is related to that revealed by staining sections of the same cells with paraldehyde fuchsin. active synthesis of neurosecret ... | 1975 | 47198 |

| chagas' disease in el salvador. | several studies on chagas' disease in el salvador have supplied important epidemiologic information, including the following: (1) rates of house infestation by triatomid vectors have ranged from 26.3 per cent to 100 per cent in various localities studied, higher rates being found in rural than in urban areas. (2) triatoma dimidiata and rhodnius prolixus are the two vectors of t. cruzi in el salvador, with t. dimidiata predominating in localities at elevations above 600 meters and r. prolixus in ... | 1975 | 808244 |
| a comparison of rhodnius prolixus, triatoma infestans and panstrongylus megistus in the xenodiagnosis of a chronic trypanosoma (schizotrypanum) cruzi infection in a rhesus monkey (macaca mullatta). | fifth instar rhodnius prolixus, triatoma infestans and panstrongylus megistus were fed on a rhesus monkey (macaca mullatta) with a chronic infection of peru strain trypanosoma cruzi and examined 30 days later for the presence of trypanosomes in the rectum. no correlation could be demonstrated between either blood meal size or sex and the subsequent development of a rectal infection with t. cruzi. as t. infestans and p. megistus were more highly infected than r. prolixus in terms of both percenta ... | 1975 | 814658 |
