Abstract

Zabrotes subfasciatus is an stored grain pest, thus it is important to select resistant bean (Phaseolus vulgaris L.) genotypes to this insect attack, in order to reduce grain damage and the use of chemical insecticides. The objective of this research was to estimate the resistance of three bean lines (CPG-0100, CPG-0040, and CPG-0117) to Z. subfasciatus attack, compared with the resistant cultivar Jamapa. The resistance was determined based upon the net reproductive rate and the intrinsic rate of natural increase, estimated through life and fertility tables. The line CPG0117 had a higher resistance than Jamapa.
