Influence of Berry Injury on Infestations of the Multicolored Asian Lady Beetle in Wine Grapes

T. L. Galvan, E. C. Burkness, and W. D. Hutchison

June 2006


The multicolored Asian lady beetle, Harmonia axyridis, is a significant pest for eastern U.S. and Ontario wine makers, but the timing of beetle infestation and its interaction with grape injury are unclear. The authors present results showing the influence of freshly injured berries on H. axyridis infestations in wine grapes, and how this relationship affects the management of H. axyridis.
