What insects will eat greenfly?
"Sacha" wrote in message ... On 2/6/04 11:58, in article , "Jane Ransom" wrote: In article , Jeff writes Hi. What insects will eat greenfly (without then becoming pests themselves)? I know about ladybirds, but are there any others? Hover flies. A hover fly can lay several hundreds of eggs on a plant and each larvae will eat up to 400 greenfly during its life time. I think that wasps also eat greenfly but am not 100% sure. Some urglers recommend (swear that the problem disappears) dotting those bird peanut feeders round the garden. The theory is that a bird will have a coupe of caterpillars for starters, a few peanuts and then a few dozen green/black/white fly for pudding!! It works for us, I must say. We have feeders in the garden and several in the greenhouses and both are alive with birds. We have wrens, blackbirds, blue tits, chaffinches and sparrows nesting in the greenhouses and all those plus thrushes in the garden. They feed on the peanuts in winter and adults will take them now, too but we often see them with their beaks stuffed with 'wrigglers' to take to their babies. Do you still have the blue tits now that they are needed to cope with the insect pests? Mine have gone to their summer quarters. Franz |

bottom line is that it is not really feasible to control pests with a population of predators. The food supply is far too irregular to maintain the defending army. Franz I think that, while encouraging beneficial insects into your garden may not entirely solve your pest problems, it does help, otherwise why wasn't the world covered in greenfly and other pests before the advent of insecticides. I also think, as another contributer pointed out futher down the thread, that the magnitude of the pest problem entirely depends upon your point of view. If you want your garden to be pristine and completely free of all pests you will probably have to use some kind of insecticide to kill them and planting nettles et al will never solve your problems, if however, you don't mind a few green fly, and would rather not use chemicals, then cultivating plants that encourage natural predators is beneficial to some extent. As an aside, I have used this method, togther with companion planting on my allotment and have never had to spray with anything in 4 years, which I think is something of a success :-) Jeannie |

In fact, one of the comments we get so often from customers is what pure joy it is both to hear the birdsong and see them come so close to people. It does give a huge feeling of privilege. I agree entirely, except that the birds you mention do not actually eat greenfly and blackfly to any noticeable extent. Franz They don't seem especially fussy as to what they eat. For all I know they also eat some of the biological control predators we use! -- Sacha (remove the weeds after garden to email me) |

What insects will eat greenfly?
In article , John Edgar
writes Do you have the right small birds? They're not all insect eaters. Bluetits seem to be the best for eating aphids, as others have said, and I often see them eating aphids on the honeysuckle outside the kitchen window. How can you have "wrong" or "right" birds in the garden? wrong or right for the purpose - in this case eating greenfly. If the only birds in your garden are seed eaters, you are not going to observe them eating greenfly. Surely you get what arrives don't you? Of course. Whether they decide to stay around depends on the conditions that you encourage, but that isn't really relevant to the point I was making. You can't choose them. I can sort of see your point though. I cannot stand magpies and chase them away at every opportunity, so I suppose, for me, they must be the wrong birds. I do the same with grey squirrels - nasty creatures. Elegant movers, and not so nasty if you're in a city where squirrels are not over abundant and any sort of wildlife is welcome. -- Kay Easton Edward's earthworm page: http://www.scarboro.demon.co.uk/edward/index.htm |

If the only birds in your garden are seed eaters, you are not going to observe them eating greenfly. In my garden, I have observed blue tits and I think also great tits rummaging round the tips of my rose bushes and honeysuckles. They don't seem to damage the plants, so I have always assumed they are eating greenfly ( I don't get that close, so maybe they are up to something else - dunno what tho). At any rate, those plants don't have a greenfly problem, though I did find the odd one here and there when I looked today. Victoria -- gardening on a north-facing hill in South-East Cornwall -- |

Bluetits seem to be the best for eating aphids, as others have said, and I often see them eating aphids on the honeysuckle outside the kitchen window. When it comes to birds, the UK differs so greatly from the PacNW that discussion is moot: entirely different species. But it is true that encouraging certain species can benefit the garden. We have a little bird here, the bushtit. (You may have it in the UK, too, but heaven's only knows if the name is used in the same way.) I enjoy putting out lumps of suet for them in the winter. Hang a nice lump of suet from a string so the rats and raccoons and such can't get at it, and watch the bushtits go to town. I've seen over a dozen on a single lump. (They're charming little birds that seem to travel in flocks of thirty or forty and come swinging through every fifteen minutes or so as they make their rounds. I put up three or four such feeding stations every year -- suet is very cheap at the local grocery store. Mirabile dictu, it turns out that the bushtits, encouraged by the suet, also work hard at cleaning up the garden. I had the great pleasure of watching one closeup through a window while it was working over a Cytisus battandieri. It took a while to figure out just what my little feathered friend was doing, but eventually I could see that he (she?) was methodically searching for, and eating, coccoons of small caterpillars. My C. battandieri is alway chewed up by some small caterpillar, and they evidently pupate in situ. Next winter, suet in the cytisus. -- Rodger Whitlock Victoria, British Columbia, Canada [change "atlantic" to "pacific" and "invalid" to "net" to reply by email] |

We grow few roses so perhaps we have fewer greenfly, as a result. ;-) -- Sacha www.hillhousenursery.co.uk South Devon (remove the weeds after garden to email me) |

It's almost as if the rooks go 'on holiday' and say to the Little Owls, "Okay, we've been waking them up at 4-5ish every morning, now it's your turn". Strange but true! AND, we have seen Little Owl babies up in the Cedar tree (don't know about nests) using it as a perch while yelling to and fro with Mum and that tree is the hub of our rookery. -- Sacha www.hillhousenursery.co.uk South Devon (remove the weeds after garden to email me) |
