Beans and Bean Beetles Our bean beetle population has been much lower for several years. We don't know whether this for­ tunate development is due to the heavy parasiti­ zation by parasitic wasps as reported in the fifth journal, "Mexican Bean Battles, " pp. 53-55, to hard winters that co uld kill overwintering adults, to improved soil conditions, or to a combination of events. In the summer of '979 we put 100 par­ as itized beetle larvae in the bean field. Evidently the wasp hatch was low, because little subsequent parasitization occurred. Bean beetle damage was not severe. We grew two old New England varieties of beans for the first time this summer, Black Beauty and Brown Beauty. Both yielded quite wel l.
