In wheat solid stems lead to non preference by the stem supply ..explain
The wheat stem sawfly is a grassfeeding insect. It causes damage to the wheat crop in the northern plains. Plant breeding is used to obtain plants with desired characteristics which are economically beneficial. It causes morphological, physiological or biochemical changes in the host plant to change the preference of insects. By using plant breeding, the stem of wheat is modified to make it solid so that sawfly get few or no larvae. Absence of larvae leads to the death of sawflies. Thus, the solid stem becomes a non-preferable plant for stem sawfly insect.
