| The potato a crop is attacked by many pests, among which the Diabrotica speciosa (Coleoptera: Chrysomelidae) is considered the main one. Because of chemical control failures associated with the requirements of integrated potato production (IPP) requiring sustainable measures, aimed to characterize advanced clones breeding program of Embrapa for resistance to insect infestation in artificial conditions. Tests were performed in a greenhouse without choice of plants and tubers of four clones of Embrapa (C2337-06-02, C2337-18-02, C2342-1-02, C2362-02-02), a standard-resistant clone (NYL 235-4) and a susceptible standard cultivar (Asterix). Results of susceptibility of 'Asterix' and resistance of 'NYL 235-4' and 'C2342-1-02', both in shoots and in tubers,... |
