| evidence of efficient transovarial transmission of culex flavivirus by culex pipiens (diptera: culicidae). | this study determined the transovarial transmission (tot) potential and tissue tropisms of culex flavivirus (cxfv), an insect-specific flavivirus, in culex pipiens (l.). several hundred mosquito egg rafts were collected in the field, transferred to the insectaries, reared to the fourth larval instar, and identified using morphological characteristics. cx. pipiens were reared to adults, allowed to oviposit in individual containers, and tested for cxfv rna by reverse transcription-polymerase chain ... | 2011 | 21936322 |
