  1. SD standard deviation; AS-CDC alive blood-fed sand flies stored at −80 °C immediately after TOSV infection; DS-CDC dead blood-fed sand flies recovered after 1 day post infectious blood meal at room temperature; DS-St dead blood-fed females left at room temperature on sticky papers and stored without EtOH; DS-St + EtOH dead blood-fed sand flies left at room temperature on sticky papers and then stored with EtOH
