- The present research was accomplished under field and laboratory conditions (T= 25[plus or minus]2[degree] C, R.H.= 70[plus or minus] 10 % and fotoperiod= 12 horas) at FCA/UNICASTELO from Fernandopolis-SP, Brazil. The feeding preference of corn bug Leptoglossus zonatus Dallas, 1852 (Hemiptera: Coreidae) was evaluated on corn genotypes AL-Bianco, AL-Manduri, AL-25 Piratininga, AL-34 e AL-Manduri in the field. Besides, some behavioral factors relative to infestation and oviposition were observed. In laboratory, the nymph's development was evaluated on ears from each corn genotype, aiming to verify the non-preference and/or antibiosis ocurrence. The females of L. zonatus preferred to oviposite on sheats from leaves. Adults and nymphs may occur in whole parts of the plants. The AL-25, AL-34, AL-Manduri and AL-Bandeirante corn genotypes were classified as moderately resistant, expressing non-preference and/or antibiosis against the corn bug. In other way AL-Bianco was the most suscetible to nymphs of the insect.
