Summary A total of 130 pools of C ulicoides biting midges collected between May and September 2012 in the Netherlands were assayed for Schmallenberg virus ( SBV ). The C ulicoides midges were caught in the same area as where in 2011 a high proportion of C ulicoides pools tested positive for SBV , in majority with a high viral load ( C t values between 20 and 30). Two of a total of 42 pools comprising 50 midges/pool of the Obsoletus complex from the 2012 collection tested weak positive ( C t values: 34.96 and 37.66), indicating a relatively low viral load. On an individual midge level, the proportion of SBV ‐infected C ulicoides of the Obsoletus complex caught in the same area and in a comparable period of the year was significantly lower in 2012 (0.1% = 1 per 1050 tested) compared with 2011 (0.56% = 13 per 2300 tested).
