Materials and methods
- Principles of method if other than guideline:
- The study was conducted on six study fields in the vicinity of St. Vith, Belgium, of which three were treated with Thiram WG 80 and three served as untreated control fields. The size of the study fields ranged from 0.60 ha to 0.90 ha. The abundance of common voles at the beginning of the study was equally distributed over both treatment groups and all study fields were farmed similarly.
The Field Phase of the study was performed from 25 June until 26 October 2012. A live trapping campaign was carried out throughout the Field Phase in order to assess the occurrence, abundance and population dynamics of common voles in the treated compared to the control fields. A total of 18 trapping sessions (one trapping session = two consecutive nights of trapping and at least one night of pre-baiting) were carried out on each study plot.
The first trapping session was conducted before the first application (four consecutive trapping nights). Ugglan multiple-capture traps were used to live-trap common vole individuals. On each study field a total of 70 traps were built up; the traps were distributed in a layout of seven rows with ten traps per row or in five rows with 14 traps per row (=study plot). The captured common voles were marked with Passive Integrated Transponders
(PITs) and released at the site of capture. The following parameters were recorded for each animal captured: species, sex, bodyweight and reproductive state. To assess whether the treatment with Thiram WG 80 had an effect on common voles, the results of the treated fields were compared with those of the control fields. For such comparison between treated and control fields, the following parameters were evaluated: trapping success and efficiency, distribution of captures, body weight, reproductive status, sex ratio and proportion of juveniles. Descriptive statistics were done for all ecological parameters. - GLP compliance:
- yes (incl. QA statement)

RESULTS
•In total 16,030 trap nights were carried out. In general, the
population size and development on control and treatment plots showed
the same pattern during the Field Phase. No differences between control
and treatment plots are detectable.
•Sex ratio was on a comparable level on control and treatment plot. The
percentages of females during the Field Phase were in the same range for
the control and treatment plots. No distinct differences were
observable. In both groups a female surplus was observable in the mid of
the Field Phase.
•Proportion of reproductively active animals was on a very similar level
in both control and treatment during the Field Phase of the study. A
high mean reproductive activity
was recorded during the summer months with a decrease in autumn at the
end of the reproductive period.
•Mean body weight was on a very similar level for juveniles, adult males
and females on control and treatment plots and in the common range of
natural populations.
•At the beginning of the Field Phase the proportion of juveniles was low
but increased during the course of the trapping period on both,
treatment and control plots. The increase of the proportion of juveniles
was in the same range for the treatment and control.
CONCLUSION
Thiram 80 WG used as a fungicide treatment at a dose of 2,400 g
a.s./ha under field conditions had no unacceptable impact on common vole
populations monitored in meadows during their reproductive period.
