    • Abstract


      Ovipositional preference of cotton leafhopper,Amrasca biguttula biguttula (Ishida) on resistant and susceptible genotyps of cotton and okra was found under the influence of chemical components. The non-reducing sugars, tannins, silica and free gossypol in the leaves showed significant and negative correlation with the number of leafhopper eggs.
