Ladybugs for Mealie control
Today I saw a local nursury had ladybugs for sale. I bought a bag of 1,800
and released them in the greenhouse. I'm gonna get that last mealie bug that crawling around in there and popping up every time I stop looking! Anyone else try Ladybugs for mealiebug control? Gene |

I tried sometime back.. but wasnt successful... most of the critters
escaped. also i was told i had the wrong species of the ladybugs (!!) . what did you buy? I need to find a way to keep them in one place... rick "Gene Schurg" wrote in message hlink.net...

Ladybugs for Mealie control
If you do a search on Google for "ladybird beetle" you will find there are
several different varieties of Lady Bugs. One specifically eats mealybugs. There are stories about how they brought this one into save the crops where mealies were killing everything. From what I read all of them eat mealies and soft bodied insects but prefer aphids and soft scale (hmmm think I saw some of that too in my plants). I figure if they can't get any aphids they will resort to whatever they can find and that will be mealies! Keeping them in place is not a problem since my Greenhouse is a closed environment except when I open the doors. I figure 1,800 Ladybugs scouring the plants for softbodied bugs is a good thing. It would take them a while to find the openings to the outside. If they move out into my garden when the weather warms that's a good thing too. I'll let you all know how this experiment progresses.

I never tried it, but I was told that you need to water well before releasing the ladybugs because if they can't find water, they will leave almost immediately. Tracey |

Ladybugs for Mealie control
Ladybugs are good for control, not eradication. The larvae are the big
mealybug destroyers. Which of course means the adults have to be happily reproducing. They need a relatively cool (moderate and definately not hot) greenhouse or cool places to hid during the heat. They need a plentiful supply of food. If you don't have a bunch of mealybugs, you might try an aphid infested branch from the garden to fatten them up for reproduction. Water must always be availableon some surface for them to drink. In short, they're not an easy fix for the problem and will more that likely be gone or dead before the job is done. If you have a balanced ecological system in your greenhouse (how many of us do?), the ladybugs will do their part. Otherwise, other than for the novelty, you've basically wasted your money and will be looking for another fix in a couple of months (or less). "Gene Schurg" wrote in message hlink.net...

I tried them a couple of years ago in my GH, and they worked fine. The
problem is that your 1800 ladybugs will eat a lot, and I certainly hope you don't have THAT big of a mealie problem. They're going to run out of food quickly and will escape in search of more or will die quickly unless you supplement the food. You can probably but bug food at the pace they came from. -- Ray Barkalow First Rays Orchids http://www.firstrays.com Secure Online Ordering & Lots of Free Info!

Ray,
I figure that if they eat their fill of mealybugs (and I don't have a huge infestation) and erradicate them it was worth the $8 I paid. I hope they do move on after that and go into my garden to eat their fill of bugs out there. If a few hang around to keep the mealybugs under control they are welcome.

That's what I thot. I have them in my light table in my house probably
because there's standing water in the resivors under the plants. They're hard to get rid of :( I've had them under control between Gnatrol and carnivorous plants and yellow sticky cards but lately they've been getting out of control so I thot I'd try a batch of ladies. I probably need to do some repotting too. Oh and I grow phrags in saucers in there too. And I was thinking to some in my greenhouse too... "Gene Schurg" wrote in message hlink.net...

Don't know if ladybugs will eat fungus gnats (sorry), but I
purchased a Drosera dichotoma 'Giant' from California Carnivores (http://www.californiacarnivores.com/) for $15. VERY easy to grow- sit it in a bowl of clean water (distilled or reverse osmosis- no salts, no fertilizer, please), give it as much light as you reasonably can, keep the humidity up, and watch it grow. This plant should be sold as a control for fungus gnats. I originally purchased it for whitefly control in a research greenhouse, but the whitefly were on their way out thanks to Marathon, so I just sat it on a bench in a pan of water. WOW. A fungus gnat magnet, that species. One grower reports that he used it to get rid of whitefly by shaking the afflicted plant, and then waving the drosera around so it would pick up the whitefly in mid-air. I can believe it. -AJHicks Chandler, AZ Sorry. E-mail address in the header won't work. |

I hope they do move on after that and go into my garden to eat their fill of bugs out there. If a few hang around to keep the mealybugs under control they are welcome. Then, especially in this case, it may be well worth putting out some additional feed for them. If you put out enought that a significant number of them can be kept happy, they will reproduce and the surplus population (defined by the number of bugs over the number that can be sustained on the food you put out) should take care of any pest organisms that find their way into your facility, and also provide a constant supply of emigrants, who'll do their duty in your garden on their way to find more food. Surely a constant supply of insect predators is better than a brief predator population explosion and crash. It is a question of understanding and exploiting population dynamics. The supplemental food you put out will ensure that some will stay around, and as they mate, some of the progeny will replace deceased "breeding stock" and the rest will emigrate, eating as they go. Some species of ant are especially useful (a practice a couple thousand years old in China and the middle east): carnivorous species, NOT leaf cutters or ranchers; are extremely effective predators, and being colonial, dependant on a queen for the integrity and survival of the colony, are easily managed to obtain effectively pest free crops. The wonderful thing about ants in this regard is that there are quite a number of suitable species around the world from pole to pole (or at least arctic circle to ant-arctic circle), so there is never a need to resort to a non-native species: one need only to study the ant species (and wasp species if you're both careful and daring) native to the area where you're growing.

But you beat me to it WRT pointing this out. ;-) It is too bad there aren't carnivorous plants that will make a meal of mammalian pests! But then I am sure animal lovers would be outraged at the notion of a plant making a meal of stray cats and puppies. I do love such critters, I realy do, as long as they aren't in my garden or in my home. Now all I need to do is find an effective way to deal with the damned critters that made off with my irises, thankfully ignored my crocus, lilies and hyacynths, and used the one end of my garden as a latrine! :-( There may be several species involved since the droppings are the size that would be left by an animal the size of a cat or small dog. Maybe I'll see if I can manage it by building something like a cold frame around the bed, or perhaps a wire cage that can be assembled and put in place in the late automn and then removed and stored just after the spring thaw. I just ordered some bletilla and cypripedium for use in that bed, and I am tempted to put them into large clay pots which I'd just place in holes in the ground so they'd be easy to remove and put inside (perhaps keeping them in the cold and dark by putting them in a spare refrigerator) once hit by frost, so as to protect them against critters; unless there is an effective way to keep herbivores out of my garden. I wonder how effective fritillaries are at keeping mammalian pests away. A colleague of mine, at work, told me that nothing he has tried in his garden has been effective. Cheers, Ted |

The only way I have heard of protecting new growth is to cage it in chicken wire.. but you have to did it down in and extend it 8-10" above the soil line. So sometimes it is easier to use traps and perimeter fencing that is 10" tall to discourage them. SuE http://orchids.legolas.org/gallery/albums.php |

If you use "chicken wire", be sure to get "aviary wire", as the mesh is only
1/2 inch. We have gophers and they get through the 1 chicken wire stuff. Paul "Susan Erickson" wrote in message ...

I realized this only AFTER I had released a bunch of bugs...as soon as I watered, they all settled down for a nice, long drink and then went leisurely about, scouring for bugs. ---Prem www.premdesign.com |

I would approach the aphid suggestion very carefully unless it's well away
from tyour orchids. We have them on some hibicus inside the house and you almost can't get rid of them. I think mealies are easier to kill. Bob |

Thanks for the link, that looks like a fun site - I'll check it out. I
sprinkle venus fly traps in amongst my orchids. They like the same conditions (humid). I don't think the fly traps consume an awful lot, but they sure seem happy.

(As a scientist, I LOVE a challenge - if something is easy, it is hardly worth doing!!!!!!) Nepenthes are tropical. So, they'd be hardy in Canada in the same sense that, say, cattleyas are hardy in Canada. The big problem with rajah and other high-altitude nepenthes is they need a huge differential in day/night temperatures. They enjoy condensation on the leaves in the morning- probably not compatible with orchids. Night temperatures should get into the low 60s, days into the 70's and 80's. In effect, they need refrigeration in most areas. N. rajah goes into decline without the temperature swings. Noisy neighbors, unfortunately, are still too big. Maybe a little selective breeding with N. rajah is called for? ;-) They're working on it, believe me. Any idea what the largest stinging nettle would be? No. Geraldo?
