Vedclass · Answer

(A) The sawfly is a pest that typically infests wheat crops. Plant breeding programs have developed specific varieties of wheat,such as $Himgiri$,which possess solid stems. Sawflies do not lay their eggs in solid stems,as they prefer hollow-stemmed varieties. Therefore,the presence of solid stems acts as a morphological resistance factor against the sawfly.
