Host plant resistance to ophiomyia phaseoli (tryon) (diptera: agromyzidae) in phaseolus vulgaris
1980
Rogers, D. J.
Fifteen entries representing thirteen cultivars of Phaseolus vulgaris were evaluated for nonpreference and antibiosis resistance to Ophiomyia phaseoli. The number of viable eggs per plant exhibited significant variation amongst the cultivars studied. No significant differences were found in the developmental period of larvae and pupae or in the size of adults emerging from the cultivars studied. Significant correlations were found between the number of viable eggs per plant and leaf hairiness, stem diameter and internode length. Low egg counts were associated with high leaf hair density, thin stems and long intemodes.
