Abstract The susceptibility of cereal, pasture, and wild
grasses to attack by Hessian fly (Mayetiola destructor (Say)) was
investigated by quantifying egglaying responses of adult females and the growth
and survival of feeding larvae. A wide range of attractiveness to egglaying
adult females was observed, not only between grass species but also within
grass species (e.g., wheat). Larval growth and development occurred on all of
the New Zealand wheat cultivars, New Zealand barley cultivars, and New Zealand
barley breeding lines that were tested. A small number of the United States
wheat cultivars and New Zealand wheat breeding lines that were tested did not
support the growth of larvae and therefore were resistant to Hessian fly. In
addition to wheat and barley, Hessian fly laid eggs and survived as feeding
larvae on couch, barley grass, and prairie grass (both wild and cultivated
species of the latter). Relative to wheat seedlings, seedlings of the
cultivated prairie grass (Bromus willdenowii `Grasslands Matua'),
appeared to be an inferior host; larvae feeding on wheat seedlings attained
greater pupal weights than larvae feeding on prairie grass seedlings.
