| spatial distribution and pyrethroid susceptibility of mosquito larvae collected from catch basins in parks in nagasaki city, nagasaki, japan. | we investigated the spatial distribution and pyrethroid susceptibility of the mosquito larvae belonging to aedes albopictus and culex pipiens group in catch basins located in parks in nagasaki city, nagasaki, japan. among the 308 parks located in the central regions of the city, 194 were investigated. cx. pipiens group larvae were collected from 31 sites; larvae of ae. albopictus, from 34 sites. the cx. pipiens group larvae were identified by pcr: 93.4% were found to belong to cx. pipiens pallen ... | 2010 | 20093757 |
| variability in circadian activity patterns within the culex pipiens complex (diptera: culicidae). | circadian activity was compared among four strains of culex pipiens molestus forskal from iran, egypt, two localities (ebira and yanagawa) in nagasaki, japan, and one strain of cx. p. pallens coquillett from japan. under a 16:8 (l:d) h photoperiod, all the strains showed peaks of activity at lights on and off, with additional activity during both light and dark periods; egyptian females and both sexes of cx. p. pallens were inactive during the photophase. under 0:24 (l:d) h, the length of the fr ... | 1994 | 8158629 |
