ladybugs

dont know what corainder smells like pat but i can tell ya that a stink bug is strong enought that even yu can smell them..the next one yu see squish and it and yu can have the expeierence that the rest of us have had:)

<a href="http://www.flowers.vg" target="_blank"><img src="http://www.pictures.vg/vgflowers this is what we call the real lady bug..its red not the orange version..

This guy nearly ate my Japanese Plum tree the first year we lived in TN... next year we put in a garden and they preferred bean plants to Plum tree.... I was beginning to think they were going to strip my pole beans to the ground.... fortunately, I found a beetle trap at Wal-mart that really worked... didn't eliminate them completely, but took about 85%... at one time I think I had over a pound of dead beetles in the trap.
 
I find them too amusing to squish but they occasionally crawl between pieces of 2x and then get squished when I move them. Still haven't noticed a smell though.

I think I need to get my nose checked out.

They didn't do much damage this year, it didn’t get hot enough. Last year, is another story. They stripped most of the trees that lined the streets. Plus, they loved anything with flowers except dandelions. :(:(:D

I did some googling and the Ladybug I listed isnt really called a LadyBug, it's the Asian Lady Beetle. Here are some facts on it.

The Multi-colored Asian Lady Beetle

  • Until the 1960’s there were no Lady Beetles in the United States, they were brought in as a way of controlling agricultural pests that eat things such as pecans and apples.
  • As a defense against predators the Lady Beetles secrete a foul smelling, yellow fluid from their leg joints. Humans would most likely only smell this fluid when there are swarms of the Lady Beetles secreting it at once.
  • Lady Beetles are attracted to illuminated surfaces such as the side of a house which is in the sun. They also are attracted to lighter colored house trim or the gutters of a home.
  • They do not reproduce once they find a home for the winter (that’s a relief). The Lady Beetles you may see leaving your home in the Spring are the same little suckers which found their way in, in the Fall.

Yeah, I didn't have quite as much damage from the Japanese beetle this year, but I got my traps out early right after the pole beans started to climb... they still left the top leaves all lacy, but not like the year before.
 
I just drove from St. Louis to Terre Haute and back and was amazed at how many i met their end on my windshield. I had about a dozen or so inside the cab as well.

Japanese Bean Beetle is what the top one is called around here, more common slang, bean beetle. Here is what I found with a quick google:
False Japanese beetles in soybean

by Marlin Rice, professor, Department of Entomology
The false Japanese beetle, Strigoderma arboricola, may be fairly common in soybean the third and fourth weeks of June. In contrast, the Japanese beetle, Popillia japonica, usually occurs during late July and August and is most likely to be found in Iowa soybean in counties along the Mississippi River or near Cedar Rapids.

False Japanese beetles are often noticed by fieldworkers because they have a tendency to land on light-colored clothing or get in ones hair. Adults are 8-12 mm in length. They are called sand chafers in Nebraska because of their preference for lighter soils and they may be abundant on heavy soils in Iowa.



Enlarge False Japanese beetle.
False Japanese beetles feed on soybean leaves, eating large holes between the leaf veins. In addition to soybean, they feed on roses and a variety of flowering plants. There is one generation per year. The larvae feed on plant roots and larval development takes 160-164 days when feeding on bluegrass roots. Adult beetles have lived for 21 days in the laboratory. No economic damage to soybean has been reported in Iowa from false Japanese beetle.

False Japanese beetle is similar in appearance to the Japanese beetle. On the false Japanese beetle, the pronotum, or "neck" is shining black, often with metallic reflections and the sides may be reddish brown. The wing covers are metallic bronze and have numerous small parallel grooves. The abdomen has five tufts of white pubescence below the edge of the wing covers, and there are no white spots on the "tail." The distinguishing features of the Japanese beetle are a dark green metallic body, reddish brown wing covers, tufts of white pubescence below the wing covers, and two white spots on the tail of the beetle.

The bottom picture you show we around here call a lady bug but is really an Asian beetle. Here is what the entomologist had to say on it.

Bean leaf beetles can knock down soybean yields

by Marlin Rice, extension entomologist, Department of Entomology
Bean leaf beetle populations have been on the increase for the past couple of weeks. Reports from western and central Iowa suggest that populations are large again this year, particularly in early-planted soybean fields. The beetles that are being seen now are part of the F1 generation; these beetles developed from eggs that were laid in the soybeans shortly after plants emerged. The next generation, or F2, is often the most damaging of the two generations, but either generation can cause damage if green pods are present in the field at the same time as the beetles are feeding. Large populations have reduced yields by 20-50 percent in past years so the importance of this insect should not be ignored.

The yellow phase of the bean leaf beetle is the most common color variety.
Some bean leaf beetles are red instead of yellow.
Some bean leaf beetles lack the "rectangular" spots on the wing covers.
Bean leaf beetles will feed on soybean leaves throughout the season, but leaf feeding seldom causes yield loss. Most damage (economic yield loss) occurs when beetles feed on the developing pods. This yield loss can occur in several ways. Pods may be clipped from the plants, or plant diseases may enter the pod from the feeding sites, causing seeds to appear shrunken, discolored, and moldy. This latter type of injury reduces seed quality.

Bean leaf beetle injury to a soybean pod.
Beetles injure pods by feeding on the outside layer of the soybean pod, leaving a thin layer of tissue still covering the seed. They do not eat into the developing seed. Grasshoppers also feed on pods but they bite completely through the pod and destroy the seed.

Begin looking for bean leaf beetles during the R4 stage (full pod) of soybean development. Scouting is no longer necessary after pods reach the R7 stage (yellow pod). Scout fields by walking 100 feet in from the field edge. Each field, and each variety within a field, should be scouted separately because bean leaf beetles sometimes concentrate in one variety and avoid another variety.

In 30-inch row soybeans, place a 3-foot wide strip of cloth (stapled to two dowel rods) on the ground between the rows. Slide the cloth under the plants and try to keep plant disturbance to a minimum before the cloth is spread between the rows and you are ready to shake the plants. Bend the plants over the cloth, and shake them vigorously when the cloth is in place. Count the number of beetles on the cloth. Repeat this procedure four times for each 20 acres in the field. Determine the average number of beetles per foot of row and then consult the economic threshold table (Table 1).

Bean leaf beetles can be shaken onto a white cloth and counted.
In narrow-row soybeans, a sweep net will be easier to use than a drop cloth. Take 20-25 sweeps in each 20 acres across the field. Determine the average number of beetles per sweep and consult the economic threshold table. For narrow-row soybeans (8-inch rows) and a plant population of three plants per foot of row, multiply the economic thresholds by 0.7 to determine an approximate threshold in narrow-row fields.

A sweep net can be used to sample for bean leaf beetles in drilled beans.
If the average number of bean leaf beetles equals or exceeds the economic threshold, an insecticide application is necessary to prevent economic yield loss (Table 2). The benefits (saved bushels of soybean) should exceed the costs (insecticide and application) and provide an economic return.

If the beetle population is less than the economic threshold, scout the field again 5 days later. More beetles could emerge from the soil, and the population could reach the economic threshold at that time. Stop scouting when

beetle counts start to decline,
soybean pods begin to turn yellow (R7 stage), or
the field is sprayed.

In the past, I have bought bags of Lady bugs to eat Aphids in my greenhouses.

Japanese Beetles are devastating on many landscape plants. They are easy to kill with the correct insecticide, but multiple sprayings are required to control the population.

If you have a Cenex or similar store, check with them for a spray. I can't remember the name but the stuff was expensive as all get out and it worked. I used it mainly for box elder bugs but it killed the asian lady bugs also. I treated the farmhouse before I rented it out. It got to be a sport to shoot them out of the air, dead on contact. I sprayed around the windows and foundation on the OUTSIDE of the house. Don't use it inside.

How do they do it? My aunt lives in a highrise Independent Living home. and this week the pesky buggers are showing up on the window ledge, walls and floor, Way up high 7th floor and windows that are sealed, I assume they have found a leak in the HVAC (built into the wall similar to what you find in a Motel) :huh:
