Locations of the populations collected in this study in Croatia and neighboring countries. Names of locations

are given in Table 1. Figure 3 Individual and mixed infections by secondary symbionts in B. tabaci populations collected in this study. 10 populations from Croatia were tested, and two additional populations from Israel were selleck kinase inhibitor tested for comparison. Each box represents one population. Vertical columns represent the different symbionts tested as indicated in the base of each column, and each horizontal column represents one individual that was tested for the presence of the six different symbionts. Gray shading represent positive infection with the tested symbiont. The geographical origin of the population, the biotype and the number of individuals tested are indicated at the top of each box. (R) Rickettsia, (H) Hamiltonella, (A) Arsenophonus, (W) Wolbachia, (C) Cardinium, (F) Fritschea. T. vaporariorum distribution and infection by secondary symbionts Fourteen T. vaporariorum populations were collected across Croatia’s coastal and continental regions as well as from neighboring Bosnia and Herzegovina and tested for the presence of secondary symbionts. T. vaporariorum

was much more prevalent than B. tabaci in most of the KU55933 in vivo regions, sometimes with heavy infestations in agricultural crops. P. aleyrodidarum, the primary symbiont, was detected in all individuals tested. Out of the six secondary symbionts tested in the collected T. vaporariorum populations, only GSK461364 concentration Arsenophonus and Hamiltonella were detected (Figure 4). Arsenophonus was more prevalent than Hamiltonella: it appeared in 71% of

all individuals tested Methane monooxygenase (107/150), as a single infection in 37% of all individuals, while the latter was detected in 40% of all individuals, and appeared as a single infection in 6% of all individuals (Figure 4). The prevalence of Arsenophonus was always higher or equal to that of Hamiltonella in all populations tested except for the population from the island Brac. Two of the populations tested were not infected with Hamiltonella (Pula and Turanj) and one population showed fixation of both symbionts (Metkovic); 34% (51/150) of all individuals tested were doubly infected with Arsenophonus and Hamiltonella (Figure 4). Figure 4 Individual and mixed infection by secondary symbionts in T. vaporariorum populations collected in this study. (14 populations were tested). See legend to Figure 3. Localization of secondary symbionts in B. tabaci and T. vaporariorum None of the controls used with the samples submitted to fluorescence in situ hybridization (FISH) showed any signal (data not shown).
