STATUS OF BACTERIAL SYMBIONTS OF THREE WHITEFLY SPECIES (HEMIPTERA: ALEYRODIDAE): Bemisia tabaci, Trialeurodes vaporariorum AND Siphoninus phillyreae IN CROATIA, MONTENEGRO AND SELECTED AREAS OF BOSNIA AND HERZEGOVINA

Whiteflies (Hemiptera: Aleyrodidae) are cosmopolitan phloem-feeders that cause serious damage in numerous agricultural crops. They harbor a primary bacterial symbiont, and a diverse array of secondary symbionts (SS) which may influence several aspects of the insect’s biology. The aim of this study was to identify the status of Bemisia tabaci (Gennadius), Trialeurodes vaporariorum (Westwood) and Siphoninus phillyreae (Haliday) in Croatia, selected locations of Bosnia and Herzegovina, and Montenegro, in terms of: geographic distribution ; infections by SS and their spatial localization in all developmental stages (from egg to adult) ; monitoring geminiviruses presence in surveyed areas, and ability of the studied B. tabaci to transmit geminiviruses. Our studies based on molecular methodology revealed: unique co-infection and localization patterns by SS in three whitefly species, which differed from previously reported studies ; absence of geminiviruses in the examined areas, but efficient geminivirus transmission by B. tabaci from infected to healthy plant in experimental conditions. Appearance of devastating geminiviruses can be expected in examined area due to specific SS composition and their presence in neighboring countries. Finally, the conducted studies contribute to investigating SS function in whiteflies, and can be used in designing programs to control these important agricultural pests.
