| isolation of spotted fever group and wolbachia-like agents from field-collected materials by means of plaque formation in mammalian and mosquito cells. | three isolations from ticks (dermacentor occidentalis) of a rickettsia of the spotted fever group and 5 isolations from chipmunk (eutamias rugicaudus) blood of a wolbachia-like agent were obtained from plaques formed in singh's aedes albopictus (mosquito) and vero (african green monkey kidney) cell cultures. these organisms could not be isolated by injection of the infected ticks or blood into embryonated chicken eggs, guinea pigs, or voles (microtus pennsylvanicus), but fluid cultures of grace' ... | 1975 | 241251 |
| [tyrophagus putrescentiae predating adult insects of aedes aegypti and aedes albopictus in laboratory]. | the present study aimed at identifying a mite infesting a colony of aedes aegypti and ae. albopictus as well as investigating the source of infestation. the mite species was identified after it was mounted on slides in hoyer's medium and examined under an optical microscope. it showed to be tyrophagus putrescentiae. fish and rabbit food samples were kept in an environmental chamber at 27 degrees c and 90% humidity for 21 days and were weekly examined. the presence of t. putrescentiae was only ob ... | 2004 | 15499448 |
| influence of multiple blood meals on gonotrophic dissociation and fecundity in aedes albopictus. | gonotrophic dissociation and fecundity in adult female aedes albopictus affect the transmission of arbovirus and mosquito population dynamics. female ae. albopictus bloodfed on guinea pig and human hosts produced significantly (p < 0.05) higher number of eggs (80 and 82/female, respectively) than females fed on chicken (67 eggs/female). fecundity in mosquitoes that took a double blood meal (chicken and guinea pig), a triple blood meal (3 separate guinea pigs), or mixed blood meals (chicken, guin ... | 2009 | 20099598 |
| a novel mosquito feeding system for routine blood-feeding of aedes aegypti and aedes albopictus. | a novel mosquito feeding system for routine blood-feeding of aedes aegypti and aedes albopictus was developed and evaluated. the system consisted of a collagen membrane casing filled with specific pathogen free (spf) mini-pig blood, which is warmed by a simple in-house designed heating device. blood feeding rate, fecundity, survival rate and hatchability of ae. aegypti and ae. albopictus colonies maintained by the feeding system were compared with those raised by conventional guinea pig feeding ... | 2012 | 22543617 |
