| [studies on esterase isoenzyme of three species of flea]. | the patterns of esterase (est) isoenzyme of 3 flea species were studied by vertical slab polyacrylamide gel electrophoresis (page). the samples prepared from the third larval instar, female and male (the unsucking and sucked one) were run in the same gel slab. the result was as follows: xenopsylla cheopis showed 14 bands, with 5-6 major bands, ctenocephalides felis felis showed 9 bands with 4-5 major bands and nosopsyllus laeviceps kuzenkovi showed 9 bands with 4-5 major bands. these three speci ... | 1991 | 1959176 |
| [the quantity of blood ingested by various species of fleas in an experiment]. | data are given on the blood amount engorged by the fleas xenopsylla conformis, x. cheopis, leptopsylla segnis, nosopsyllus laeviceps, n. consimilis, ctenophthalmus golovi, neopsylla setosa, citellophilus tesquorum and coptopsylla lamellifer. the average weight of blood portion in females of different species engorged for the first time ranged from 0.05 mg (x. conformis) to 0.72 mg (c. lamellifer). females of most species, which had multiple blood meals, engorge more blood. males engorge less blo ... | 1988 | 3205580 |
| blood-feeding of the gerbil flea nosopsyllus laeviceps kuzenkovi (yagubyants), vector of plague in inner mongolia, china. | the gerbil flea nosopsyllus laeviceps (wagner) (siphonaptera: ceratophyllidae) is an important palaearctic vector of enzootic plague among sylvan and campestral rodents. laboratory blood-feeding experiments with the subspecies n.l.kuzenkovi (yagubyants) from inner mongolia, china, using three rodent species including the natural host meriones unguiculatus (milne-edwards), demonstrated a positive relationship between per cent feeding and time allowed for feeding, particularly for female fleas. al ... | 1993 | 8435489 |

| [epidemics and risk factors of plague in junggar basin, xinjiang uygur autonomous region, 2007-2016]. | objective: to explore the epidemic situation of animal plague in junggar basin natural plague foci. methods: data on epidemics of plague and on population involved, as well as results on antibodies and pathogens, were analyzed. samples on animals and vectors were collected from 18 counties in junggar basin plague natural foci between 2007 and 2016. results: the density of rhombomys (r.) opimus was temporally fluctuant, from 2.1/hm(2) to 22.6/hm(2) respectively. however, the spatial distribution ... | 2017 | 29060987 |
| development and longevity of nosopsyllus laeviceps kuzenkovi (siphonaptera) from inner mongolia under laboratory conditions. | the development and longevity of nosopsyllus laeviceps kuzenkovi (yagubyants), a major plague vector among sylvan and campestral rodents in inner mongolia, china, was studied under controlled laboratory conditions of 11, 14, 17, 20, 23, 26, 29, and 35 c at 76% relative humidity (r.h.), and 32, 53, 76, 87, and 100% at 23 c. development from egg to adult was shortest (21-23 days) under favorable conditions of 26 c at 76% r.h., but maximum survival to adulthood (84%) occurred at 23 c. average longe ... | 1993 | 8459329 |
