When this state introduced beetle appeared in my yard late last summer it afflicted a African Yellow Yam in my south bed.....not too many though. This year however it has begun attacking vigorously the few Air Potatoes I have here after years of my fighting them. What worrisome is that last year they affected several of Andy Firk's edible yams, and one of my student's edible yams in Temple Terrace. Paul Zmoda has VERY similar damage (though he has not yet seen them in the act) on Passion Flower and Virginia Creepr, which is in the Grape Family...and Paul has a vineyard. I LOVE my edible yams and my three kinds of grapes....I sure hope this beetle (from Nepal I think) does NOT destroy crops other than Air Potato! John
