Abstract	Organic Management of Mexican Bean Beetle (Epilachna varivestis Mulsant) Infestations in Snap Bean (Phaseolus vulgaris L.) Crops Tiffany L. Fess Various methods have been suggested to control or deter MBB from attacking bean crops, however conclusive data detailing the effectiveness of control methods and their effects on green bean yield are limited. Two separate experiments were performed to compare MBB management practices in snap bean crops and determine snap bean varieties with natural tolerance to MBB infestations. P. foveolatus in snap bean crops significantly(P<0.05) reduced the larval and adult MBB populations, while increasing the bean yield in optimal growing conditions. The use of row cover and staggering of planting date proved to be unsuccessful (P>0.05) increasing bean yield, however MBB larval, pupal, and adult populations were found to be different (P<0.05) when growing conditions wee optimal. When MBB populations were above the economic threshold (11.5 MBB larvae per plant) in the test, tolerance to MBB infestation was not observed (P>0.05) in any of the varieties studied.
