Soybean lines PI 229.358, PI 171.451 and PI 227.687 were reported to be resistant to Mexican bean beetle (Epilachna varivestis) (Van Duyn, Turnipseed and Maxwell, 1971). Their study was based on forced feeding tests conducted in the laboratory and by field observations. The line PI 229.358 has been intensively used by soybean breeders for incorporating resistance into corrmercial germplasm .
