Abstract
The multicolored Asian lady beetle (Harmonia axyridis), hereafter MALB, is a Palearctic species that established relatively recently in eastern (Chapin and Brou 1991) and western North America (Dreistadt et a1. 1995). Populations of MALB have expanded throughout eastern North America (McCorquodale 1998) and among western coastal states (LaMana and Miller 1996). MALB was discovered in North Dakota in September 2000 (Fauske et a1. 2003). It currently is known from seven counties in eastern and northern North Dakota, based on one to two specimens per county (Fauske et al. 2003). MALB also has been found in South Dakota and Minnesota (Hesler et al. 2001, Fauske et al. 2003). Relatively large autumnal aggregations of MALB are known from South Dakota and Minnesota (Hesler et al. 2001), but previously only one to two MALB had been sampled in summer from various areas in North Dakota, South Dakota, and Minnesota (Hesler et al. 2001, Fauske et al. 2003).
