Thurmont, Md. -- First it was the multi-colored Asian lady beetle (MALB) invading Eastern vineyards and imparting a nasty flavor to the wines. Now it’s a stink bug from China. The East has always had several kinds of native stink bugs that have co-existed with orchards and vineyards without causing any major problems, mostly because these half-inch long, shield-shaped insects did not seem to feed on fruit.
