Larvae complete their development on plants where their primary food (aphids) is abundant. The immatures (larvae) are often orange and black and shaped somewhat like tiny alligators. Most beetles have a small, dark "M" or "W"-shaped marking on the whitish area behind the head.Įggs are yellow, oval, and typically are laid in clusters on the undersides of leaves. Multi-spotted individuals tend to be females while those with few or no spots tend to be males. They often have several black spots on the wing covers, although on some beetles the spots may be indistinct or entirely absent. Their color can vary widely from tan to orange to red. DESCRIPTION AND HABITSĪdult Asian lady beetles are oval, convex, and about 1/4-inch long. originated not from these intentional releases, but from beetles accidentally transported into New Orleans on a freighter from Japan.
No such releases were ever attempted in Kentucky, and their occurrence here is probably due to northward migration from other southern states. Some scientists believe that current infestations in the U.S. Large numbers of the beetles were released in several states including Georgia, South Carolina, Louisiana, Mississippi, California, Washington, Pennsylvania, Connecticut and Maryland. Department of Agriculture attempted to establish the Asian lady beetle to control agricultural pests, especially of pecans and apples. Earliest records in Kentucky date back to a few specimens collected in Hickman County in 1992.ĭuring the 1960s to 1990s, the U.S. Since then the beetle has expanded its range to include much of the U.S. The first field populations in the United States were found in Louisiana in 1988. The beetle is native to Asia (e.g., China, Russia, Korea, Japan), where it dwells in trees and fields, preying on aphids and scale insects. The Asian Lady Beetle, Harmonia axyridis (Pallas), is relatively new to this country. They have an average life span of about 10 days so if you keep it up, they will be gone within 2 weeks, easy.In many areas of the U.S., these autumn invasions are such a nuisance that they affect quality of life. Top up the liquids as needed and keep the place clean for about 10 days to 2 weeks. The flies will be drawn to the scent and will go in for a snack, but the soap lowers the surface tension of the liquids and they will get stuck in it, eventually drowning. Lay your devilishly delicious smelling trap somewhere that the flies seem to be gathering in large groups. Drizzle some liquid dish soap into the mix. Now for your secret ingredient: dish soap. The stronger the sweet smell, the better. Pour in some maple syrup, soya sauce, honey, any mix of random sweet sticky liquids you can find. You're going to make the little buggers a meal. These things like to eat.Ģ) Grab a small container. Scrub away any spilled syrups or anything that has sugar.
Leave no piece of fruit, bread, sweet sticky thing behind. Anything organic that isn't in a very sealed container has to go. The fastest way I've found to get rid of fruit flies is this:ġ) Clean.
