Abstract
AbstractForty exotic maize inbred lines from 10 countries with known resistance or susceptibility to the European corn borer, Ostrinia nubilalis (Hübner), were used to study the effect of plant resistance on borer survival from natural overwintering conditions and particularly the fecundity of the female moth during the following summer. Also, additional information was obtained on different biological characters of the insect. Resistant and susceptible lines were grouped according to their leaf feeding ratings (antibiosis), per cent borer survival at pollination time or at harvest (tolerance). Each specimen observed was kept on the same plant tissue until pupation. The number of eggs and egg masses/female was significantly higher only when lines are grouped according to their leaf feeding ratings. No significant differences were obtained in most biological characters of borers fed on resistant or susceptible maize lines: spring pupation, pupal parasitism, mortality and weight, moth emergence and sex ratio.
