Interspersed refuge extends midge tolerance
Without an interspersed refuge system,
midge tolerance could break down within 10 years.
If midge tolerant wheat is grown in
a pure stand, only the small
number of naturally occurring
virulent (resistant)
midge survive.
The virulent midge would
mate only with other
virulent midge.
An interspersed refuge system could extend the life
of midge tolerance to 90 years or longer.
A large virulent population
quickly builds and feeds
on tolerant varieties.
Virulent Midge
Tolerant Wheat
Non-virulent Midge
Susceptible Wheat
Non-virulent midge survive
on the 10% susceptible plants
interspersed throughout
the wheat field.
The non-virulent midge
would inter-mate with
virulent midge.
The progeny of this cross would
be non-virulent. This prevents a
build up of a large virulent
midge population.
