    Information on zoonotic Onchocerca species and their black fly vectors is reviewed in relation to zoonotic onchocerciasis in Japan. Ten Onchocerca species are known in five kinds of ungulates in Japan: O. cervicalis in horse (Equus caballus); O. gibsoni, O. gutturosa, O. lienalis and O. sp. in cattle (Bos taurus); O. suzukii and O. skrjabini in Japanese serow (Capricornis crispus); O. eberhardi and O. skrjabini in Japanese deer (Cervus nippon); O. dewittei japonica and O. takaokai in wild boar (Sus scrotus). Onchocerca dewittei japonica was determined as a causative agent of all 10 human cases of zoonotic onchocerciasis that occurred in Japan. Simulium bidentatum was found to be a natural vector of O. dewittei japonica. Five other black fly species, S. arakawae, S. japonicum, S. oitanum, S. quinquestriatum and S. rufibasis, were implicated as potential vectors of O. dewittei japonica. Natural vectors of other Onchocerca species were S. bidentatum for O. takaokai; S. arakawae, S. daisense and S. kyushuense for O. lienalis; S. arakawae, S. bidentatum, S. daisense and S. oitanum for O. sp., and potential vectors were S. arakawae and S. oitanum for O. takaokai; S. arakawae, bidentatum and S. oinatum for both O. eberhardi and O. skrjabini.

    An autochthonous dengue patient was confirmed on September 8, 2014 in Chiba City, Japan and emergency control against potential dengue vector Aedes albopictus was implemented in the residential area where the case was found. We examined the distribution of human dwellings and areas with trees and bushes in the residential area by using an aerial photograph, selected an operation area within 100 m radius of the patient’s house, and carried out vector survey and insecticide spray in the operation area. The mean biting density of Ae. albopictus examined at six collection sites within the operation area was 2.8/person/8 min before insecticide applications. Etofenprox 7% and phenothrin 10% diluted 1/50 were applied to adult resting sites and larval habitats of Ae. albopictus at a rate of 500 mL/m2 and 50 mL/m2 with a power-driven sprayer and hand-pump sprayers, respectively. Additionally, a liquefied carbon dioxide formulation of phenothrin was applied at a rate of 1 g/m2 to drains with a heavy cover. The mean biting density was reduced to 1.2/person/8 min on the same day after insecticide application, and weekly inspections of the operation area in the following 3 weeks found a total of four mosquitoes.

  • Proposal to correct the date of publication of nomenclature described by Dr. Tokuichi Shiraki in “Blood-sucking insects of Formosa. I. Tabanidae”

    The year of publication of Dr. Tokuichi Shiraki's “Blood-sucking insects of Formosa. I. Tabanidae.” was misprinted as 1918 in the English cover, and all of the following papers cited the thesis as published in 1918 and the date of publication of scientific names of new genus and species described in the thesis to be 1918. I found the date of publication written in Japanese on the back cover colophon as 31 March in Taisho 8 (=1919). The published date of the thesis should be corrected to be 31 March 1919. Based on “the Recommendation 21F. Correction of data” by ICZN, I propose to correct the date of publication of scientific names of one genus and 13 species described as new to science in the thesis from 1918 to 1919. In addition, no synonym relation is occurred when the date is corrected.
