About the Lab

The Insect Diagnostic Lab was established in 1978 to identify insects and insect damaged plant material from around the state. Primary service is to the county extension offices and commercial concerns. The location of extension offices in Wisconsin can be found at http://www1.uwex.edu/ces/cty. The lab processes between 1,500-2,300 samples per year. Homeowners are encouraged to check with the local extension office for help first because many samples can be handled in a more efficient manner locally. Mail in samples, e-mails (with pictures if possible) and walk in samples are accepted. At the present time there is no charge for the service.

Submitting Insect Samples

Crushed, damaged specimens are very difficult to identify. Use mailing tubes, padded envelopes or sturdy boxes to prevent damage when shipping. DO NOT PUT SPECIMENS ON TAPE. Use cotton, or tissue paper for cushioning. Tape vial or film canister tops before shipping. Many specimens are damaged in transit if not cared for.

Hard bodied insects such as beetles and true bugs can be placed in a small clean vial. Put cotton or tissue paper inside the mailing tube with the specimen and increase its chances of arriving intact.

Soft-bodied insects such as aphids, caterpillars and other worms are best preserved in alcohol. Freezing or placing in very hot water can kill specimens. Seventy percent ethanol is best but rubbing alcohol, or clear cocktail alcohol like gin or vodka works in a pinch.

Adult moths and mosquitoes have scales on the wings that are needed for identification. They need to be kept dry. Do not crush. Place carefully in a vial or tub. Cushion during transit.

If you suspect you have insect damaged plants, collect plants that show a range of symptoms. Including healthy plants with your damaged plant sample can help in detecting subtle symptoms.

Keep collected plants as fresh as possible. If possible, collect plants immediately before they are to be mailed or brought into the lab. If there will be a delay, keep the plants cool. Plants collected from home gardens can be kept in your refrigerator.

Because the sample may have a plant disease, keep foliage from becoming contaminated with soil. Wash roots gently to remove soil unless the sample is to be tested for nematodes or you are submitting a potted plant.

Collect other important information. The diagnosis process often involves piecing together many different clues. Background information is crucial. When submitting a sample, include the following information about:

THE PLANT

(name, variety, age)

SYMPTOMS

(unusual plant size, color or shape, severity of the disease)

THE ENVIRONMENT

(weather patterns just prior to the onset of disease symptoms, soil type where the plants are growing, amount of water that the plant has received, and the amount of sun or shade that the plants receive)

MANAGEMENT FACTORS

(fertilizers and pesticides that you have used, pesticides used by your neighbors, if known).

Leaves and flowers.

Press leaves flat between alternate layers of moist (NOT WET) and dry paper towels. Put leaves and toweling between two pieces of cardboard and put into a plastic bag. Tie the bag closed. Punch several holes in the bag to allow air movement. Place the wrapped leaves in a box. Use packing material to ensure that the sample won't shift during shipment.

Woody branches.

Cut branches into sections. Place the pieces in a plastic bag and place the wrapped material in a box. Use packing material to ensure that the sample won't shift during shipment.

Evergreen branches.

Place branches in a plastic bag and tie the bag closed. Punch several holes in the bag to allow air movement. Place the wrapped material in a box. Use packing material to ensure that the sample won't shift during shipment.

Fleshy fruits and vegetables.

Wrap fruits and vegetables in dry newspaper. Place fruit/vegetable and newspaper in a plastic bag and tie the bag closed. Punch several holes in the bag to allow air movement.
