experiments on chickens placed on ground endemic of classical scrub typhus in akita prefecture, japan. | the chicken is available as a bait animal for the study of vector mites and has been found to be infected by chigger mite bite in an area endemic of scrub typhus. l. pallidum and l. palpale were reconfirmed to be zoophilic for the chicken. it is suggested a walking bird can serve as a vector--carrying mites from one place to another. r. orientalis can persist subclinically for a certain period in the spleen and liver of chickens placed on the gound endemic of scrub typhus. specimens of l. pallid ... | 1976 | 823258 |
[ectoparasites of small mammals in the eastern portion of the baikal-amure mainline]. | 11.501 ectoparasites of 45 species were collected from small mammals (rodents, shrews and double-toothed rodents) in the north-eastern part of priamurje. the parasitecoenoses are formed in general by gamasid mites (60.4%) and lice(24.7%) but faunistically fleas (19 species or 42.2%) are dominant. among all ectoparasites the gamasid mites, laelaps clethrionomydis and hirstionyssus isabellinus, and the louse hoplopleura acanthopus account for 64.9%. the impoverishment of the arthropod fauna in the ... | 1978 | 733323 |

[siphonaptera/fleas (author's transl)]. | fleas are small, reddish-brown, wingless insects with a laterally compressed body and a pronounced third pair of legs adapted to leaping. of the 100 species found in middle europe, hardly a dozen are of medical importance, they concern mainly people in contact with domestic animals. the cat flea, ctenocephalides felis felis, and the bird flea. ceratophyllus gallinae, are the most important human-pathogenic species in our region. a flea bite shows first as a haemorrhagic punctum, accompanied by i ... | 1979 | 493245 |
field evaluation of dimethoate as a systemic for the control of chigger mites in the pescadores island of taiwan. | a 0.25% concentration of dimethoate applied as a surface coat on bait grain was evaluated in an open field trial in the pescadores islands of taiwan for the systemic control of chigger mites. unsatisfactory levels of control were observed on all 4 species of mammals studied. chigger control with systemics does not appear practical at this time. | 1979 | 483017 |
isolation of rickettsia tsutsugamushi from mammals and chiggers (fam. trombiculidae) in the pescadores islands, taiwan. | 1978 | 418538 | |
numbers of leptotrombidium (leptotrombidium) deliense (acarina: trombiculidae) and prevalence of rickettsia tsutsugamushi in adjacent habitats of peninsular malaysia. | numbers of l. (l.) deliense larvae were determined in adjacent habitats over a 16 month period. both r. argentiventer and r. tiomanicus were highly efficient hosts for l. (l.) deliense. r. argentiventer was host to significantly greater numbers of chiggers per rat than was r. tiomanicus. the 2 habitats were similar in numbers of chiggers collected. no consistent correlation was apparent between numbers of chiggers and any single weather factor, but the chigger population seemed to be adversely a ... | 1977 | 411177 |
chigger (acarina:trombiculidae) surveys of the west coast beaches of sabah and sarawak. | leptotrombidium (leptotrombidium) arenicola traub, a vector of scrub typhus, had previously been found to occur in the coastal vegetation behind the edge of open sand along the beaches of peninsular malaysia. surveys of the west coast beaches of sabah and sarawak were conducted to determine if this species occurs in similar habitat in east malaysia on the island of borneo. leptotrombidium (l.) arenicola was not collected from the eighteen sites studied. of the 11,982 mite larvae collected, 55 pe ... | 1977 | 411176 |
[new species and new finds of trombiculid mites of the genus leptotrombidium in tadzhikistan (trombiculidae)]. | new species of chiggers from tadzhikistan are described: leptotrombidium tamanta sp. n. differs from all other species in having pubescent dorsal and lateral setae on the tibia of palps; l. derlatkoi sp. n. and l. apertum sp. n. are similar with l. smirnovi kudryashova et ribin, 1974, from which the former differs in having in the first dorsal row 8 setae instead of 10 and in certain sizes and the latter--in having a smaller number of setae on the body, short barbs on the dorsal setae and sizes. ... | 2007 | 158738 |
[new genus and 2 new species of chiggers (acariformes, trombiculidae) from lizards]. | the genus lacertacarus g. n. is close to neotrombicula differing from the latter in lanceolate dorsal setae, wide shield and other characters. lacertacarus includes two new species, l. similis sp. n. and l latus sp. n., and trombicula callosa schluger, 1966 described earlier. descriptions and key to species of the genus are given. larvae were collected from lizards in the krasnodar territory, georgia. | 2007 | 142948 |
[new species of chiggers, straelensia taurica sp. n. (acarina, leeuwenhoekiidae, apoloniimae)]. | a new species of the trombiculid mites, straelensia taurica sp. n., is described. the mites were found on the hare lepus europaeus in the crimea. the new species is closely related to straelensia europaea vercoammen--grandjean et kolebinova, 1968 and s. africana vercammen--grandjean, 1971 but differs in the measurments: size (ip=558), galeal seta (ga=b) and other characters. | 1975 | 130604 |
rickettsia tsutsugamushi infections in chiggers and small mammals on a mature oil palm estate. | an epidemiological study in a mature oil palm estate in peninsular malaysia has demonstrated a low prevalence of r. tsutsugamushi infection in small mammals. the direct fluorescent antibody technique for assaying infections in chiggers proved more sensitive than mouse inoculation. most infections in both chiggers and rodents were caused by the karp strain. | 1978 | 107596 |
identification and antigenic typing of rickettsia tsutsugamushi in naturally infected chiggers (acarina: trombiculidae) by direct immunofluorescence. | rickettsia tsutsugamushi organisms were detected and typed antigenically by direct immunofluorescence in mites from laboratory-maintained infected colonies of leptotrombidium (leptotrombidium) fletcheri and l. (l.) arenicola. rickettsiae were identified most readily in unengorged larvae, but were also discernable in engorged larvae and all post-larval stages of the vectors. | 1978 | 103449 |
stylostome formation by leptotrombidium mites (acari: trombiculidae). | the modes of stylostome formation by larvae (chiggers) of leptotrombidium intermedium, l. fletcheri, l. arenicola, and l. deliense in parasitized mouse skin were studied histologically in relation to their capacity to transmit rickettsia tsutsugamushi. three types of stylostome formation were recognized among the different species: the epidermal stylostome formed by the larva of l. intermedium; the mesenchymal stylostome formed by the larva of l. fletcheri; and, the mixed stylostome formed by th ... | 1978 | 98623 |
area control of chigger mites with granules and concentrated sprays of chlorpyrifos. | 1978 | 75217 | |
keys to the genera of chiggers of the western hemisphere (acarina: trombiculidae). | synotpic keys to the 87 genera of chiggers in the western hemisphere (nearctic and neotropical regions) as well as illustrations to the terminology employed, are presented. | 1977 | 68115 |
ultrastructural comparison of the midgut epithelia of fleas with different feeding behavior patterns (xenopsylla cheopis, echidnophaga gallinacea, tunga penetrans, siphonaptera, pulicidae). | this morphological study describes the ultrastructure of the midgut of three flea species, including temporary parasitic fleas (both sexes of xenopsylla cheopis, males and immature females of echidnophaga gallinacea and tunga penetrans) and stationary parasitic fleas (mature females of e. gallinacea and t. penetrans). (1) three cell types (a,b,c) constitute the midgut epithelium, each appearing in a characteristic and constant frequency along the whole midgut, a) the functional digestive cells f ... | 1976 | 8972 |
