| natural vectors of three bovine onchocerca species (nematoda: onchocercidae) and seasonal transmission by three blackfly species (diptera: simuliidae) in central kyushu, japan. | eleven blackfly species were examined in relation to the transmission of bovine onchocerciasis in central kyushu, japan. a total of 19,005 out of 47,746 females captured from june 1989 to june 1990 at two cattle sheds each in oita and kumamoto were dissected for their parities, infections with onchocerca larvae, and intakes of onchocerca microfilariae. overall results showed that simulium bidentatum (shiraki), the predominant species, is a natural vector of the two bovine onchocerca species, i.e ... | 1994 | 8057315 |
| effects of constant temperatures on oviposition and immature development of simulium bidentatum (diptera: simuliidae), a vector of bovine onchocerca (nematoda: onchocercidae) in central kyushu, japan. | laboratory developmental studies were carried out on simulium bidentatum (shiraki) under constant air and water temperatures (7, 10, 13, 16, 19, 22, 25, and 28 degrees c). the median time required for female flies to complete oocyte maturation after blood feeding decreased from 8 to 1.5 d and the median time from blood feeding to oviposition decreased from 16 to 3 d as air temperature increased from 7 to 28 degrees c. air temperatures from 16 to 22 degrees c were most suitable for oviposition. a ... | 1995 | 8551502 |
| molecular identification of infective larvae of three species of onchocerca found in wild-caught females of simulium bidentatum in japan. | wild female black flies attracted to a man or an idling automobile were collected at oita, japan where five cases of zoonotic onchocerciasis had occurred. among the five simulium species captured, 2% of simulium bidentatum, the predominant species, were infected with filarial larvae. there were at least two types of infective larvae, types a and b, based on morphometric observation. moreover, molecular analysis of the mitochondrial cytochrome c oxidase subunit 1 (co1) gene revealed that types a ... | 2010 | 20387737 |
