Article Figures & Data

Figures

  • FIG. 1.
    FIG. 1.

    Distribution of the 36 apiaries where samples were collected in France. The reference numbers of the apiaries are indicated.

  • FIG. 2.
    FIG. 2.

    Frequencies of bee virus infections in samples of adult bees (A) and pupae (B) collected from 360 colonies. The data are expressed as percentages. The detection of DWV, SBV, CBPV, ABPV, BQCV, or KBV in the spring, summer, and autumn in the same colony is referred to as stable. Viral infections that were detected once or twice during the year in the same colony are referred to as variable. Not detected refers to colonies in which virus was not detected at any time of the year.

  • FIG. 3.
    FIG. 3.

    Percentages of apiaries in which 0 to 10 colonies were infected by DWV, SBV, BQCV, or ABPV at the adult or larval stage.

  • FIG. 4.
    FIG. 4.

    Seasonal variation of viral infection rates in honey bee colonies.

  • FIG. 5.
    FIG. 5.

    Prevalence of viral infections in V. destructor samples.
