Bacterial community survey of Solenopsis invicta Buren (red imported fire ant) colonies in the presence and absence of Solenopsis invicta virus (SINV).

摘要: Insect bacterial symbionts contribute to many essential biological functions of their hosts and can also influence host fecundity fitness. The physiological contribution provide aid in immune response xenobiotic detoxification. Both these factors directly impact strategies aimed at managing insect populations. One control strategy that shows promise insects is the use single-stranded RNA viruses within group Dicistroviridae. Solenopsis invicta Virus (SINV; Dicistroviridae), a ssRNA virus, has been proposed as potential agent for urban pest S. Buren or red imported fire ant (RIFA). SINV shown be prevalent RIFA populations Texas Florida; however, mortality associated with high viral load. In other microbe systems, presence particular bacteria induced resistance against Dicistrovirus. If this type relationship present RIFA–SINV system, community could reduce effectiveness system. advantage 454 pyro-sequencing it enables classification unculturable bacteria. This study examines brood, workers, reproductive cast members from colonies without infection. Manipulation may alter virus infection replication mid-gut. Understanding differences microbial insights will refine current efforts designing important pest.
