Natural occurence of Fusarium graminearum on adult wheat midge and transmission to wheat spikes
2000
Mongrain, D. | Couture, L. | Comeau, A.
To determine the presence of Fusarium graminearum on wheat midges (Sitodiplosis mosellana), adult females were captured from a spring wheat (Triticum aestivum) field near Quebec City (Canada) and plated on potato dextrose agar. A month aspirator was used to capture live midges in sterile vials. F. graminearum was isolated from 2.1., 5.3 and 0.6% of midges captured in 1997, 1998 and 1999, respectively whereas other Fusarium spp. were isolated from 2.5% of the midges in 1999 and from none in 1997 and 1998.
