Fourteen genotypes (varieties) of soybean (Glycine max) were screened for levels of induced resistance to Mexican bean beetle (Epilachna varivestis) damage, and a subset of 6 of those varieties was screened for levels of constitutive resistance to Mexican bean beetles. Experiments were carried out in the greenhouse, with damage imposed by Mexican bean beetle larvae, and levels of resistance measured by a choice test bioassay with adult beetles. We found significant variation among soybean genotypes in levels of both induced and constitutive resistance. We found no significant correlation between levels of induced and constitutive resistance measured in the same genotypes. We compare these results to past work on resistance in the soybean-Mexican bean beetle system, consider the implications of variation in both types of resistance for plant-herbivore interactions in agricultural and natural systems, and discuss the relationship between induced and constitutive resistance.
