I can tell it’s spring in Kansas, because the aphids are out in full force. The one downside to having lots of Asian greens and radishes in the Demo Garden this year is that the aphids are pretty much in 7th heaven! I don’t know quite what it is, but aphids LOVE those brassica greens.
However, I found some aphids in a place I wasn’t really expecting to find them: the apple trees! I had thought that they were woolly apple aphids, until I did a search and discovered that they aren’t actually those kind of aphids. I think they are just an average type of aphid that happens to like one of the apple trees. So what clued me into the presence of the aphids?
Can you see what’s going on here? I happened to notice on Saturday that some of the larger leaves were curled up abnormally. I guess this is why it is so important to walk through your garden and notice the little details regularly. Many people may not have notice these symptoms for some time yet.
UPDATE: My husband sent me this story, that is pretty intriguing. Apparently aphids change their color in certain cases because a fungus facilitates the aphids assimilating the genes that cause synthesis of carotenoids!
