I have a large number of genera and families represented in my collection, and I have found bulb fly larvae only in Narcissus, Galanthus, and Sternbergia. I now cover all the sternbergias and galanthus with screens or Reemay before the flies emerge but the narcissus are so scattered around and so many of them that I haven't grouped and covered them yet. I squeeze the bulbs hard when I lift them to test whether they have grubs -- the species I grow in the frames are all quite small so this is effective though very disgusting. This year spring was very cold for a long time, and the flies did not emerge until about a month later than I have seen them before; they must emerge in response to soil temperature (the larvae pupate in the soil, not inside the bulbs)? Anyway, so far I have found very few infested narcissus bulbs, and no pot with more than one bad one. Jane McGary Northwestern Oregon, USA
