Some of the reasons I don't spray pesticides ...
Every spring I notice at least one or two colonies of bumble bees living
in the garden. They do a fabulous job of pollinating in the early spring, long before the other pollinators appear. They feast on the Pulmonaria and Vinca from early April on, and then get busy with the myriad, sweet-smelling blooms of the wild black currant in mid-month. No blooms in the garden wants for their attention all season long. A big clump of ladybugs hibernated somewhere at the base of the plum tree. They marched out one sunny spring morning and got right to it. Their children and grandchildren have been controlling the aphids, not just on the fruit trees and the roses, but in most of the garden as well. I grow an abundance of flowers for bees and butterflies on the sunny south facing slope ... and if you grow them, they will come. The Monarchs are starting to show up now, fluttering among the echinacea and the butterfly bushes. Sometimes, in the fall, I see them swarming overhead before they head south across the lake. I leave the seed heads in the wildflower slope up for the winter. By early spring, all the seeds have been eaten by local birds and the hungry migrants returning from places I'd rather be. EV |

They prefer soft bodied insects such as aphids, but will also eat other bugs, including their own kind. I've documented them in the larval stage cannibalizing one another. Ladybugs don't eat fruit or vegetation of any kind ... and that's a good thing. EV |

The imported Asian lady beetles certainly eat fruit. I've seen them by the hundreds in my apples; I don't think they will attack a perfect apple, but once yellow jackets or birds or something make a little hole in the apple, the ladybugs go after it. They enlarge the hole, which then attracts more ladybugs. They are a big problem for grape growers because when they get inside the grapes, they stink up the juice when the grapes are crushed and they can easily ruin the wine. At least with a ladybug infested apple, you can see them. BTW, they also bite people. Bob |

They enlarge the hole, which then attracts more ladybugs. Interesting. I hadn't heard of this. But I did find some puzzling evidence on my plums. The first time I saw them years ago, I thought they were ladybugs that had somehow died just before becoming fully formed adults. I thought they were must resting on the fruit to morph and had died. Then, when everyone brought up plum curculios as a big probelm on plums, I checked some sites to see what they looked like, and though my bugs don't look like the adult PC, I thought they might be a pre-adult stage not shown. Now I'm wondering again. They are a big problem for grape growers because when they get inside the grapes, they stink up the juice when the grapes are crushed and they can easily ruin the wine. At least with a ladybug infested apple, you can see them. The stupid thing is that the asian ladybugs were imported as beneficials in vast numbers. Now, thanks to them, native ladybugs have been extirpated almost everywhere the asian has been introduced. Good intention, very bad idea. I get the chills whenever I hear about another insect they want to release to combat some alien that was accidentally imported and has no natural enemies. Importing alien bugs to battle alien bugs or plants is a dumb idea at best. New studies show that the main advantage that alien imports (insects, mollusks and plants) have is that their usual parasites don't exist here. Whereas they may be preyed upon by a dozen parasites on their home turf, here there are just a few at most. BTW, they also bite people. This I know! :-D The first few times I transported ladybug larvae to the rose buffet by hand, the little buggers bit me. I transported them in plastic cups after that. They're now everywhere so I don't have to move them around. I didn't introduce them here. They were very well established when I moved here. EV |

Mexican bean ladybug, aka Mexican bean beetle and the squash ladybug are plant feeders. ...I believe the reason the larvae cannibalize each other is to get a protein that triggers the the stoppage of the the juvenile hormone that now allows them to pupate and become an adult. Lar. (to e-mail, get rid of the BUGS!! It is said that the early bird gets the worm, but it is the second mouse that gets the cheese. |
