Service Description:

The predicted wheat stem sawfly development dataset provides an estimate of the growth index of wheat stem sawfly (Cephus cinctus). The growth index describes the potential for population growth, based on long term normals of temperature and precipitation (abiotic factors).

Wheat stem sawfly adults are 8-13mm long and have a shiny, black, wasp-like body and yellow legs. When at rest on plant stems, they point their heads downwards. Mature larvae overwinter in the base of stems in infested fields. In June, females emerge and fly to nearby wheat crops, where they can lay up to 50 eggs each on stems.

The wheat stem sawfly feeds primarily on spring and durum wheat, though winter wheat, rye, grain corn, barley, and some native grasses can support sawfly development. It cannot develop on oats. Larvae feed on the pith of host plants stems which can cause a reduction in crop yield and quality. When plants mature, larvae move to the bottom of the stem to overwinter.
