Sunflower Insects

Wireworms (Elateridae) and False Wireworms (Tenebrionidae)

Many species of wireworms and false wireworms attack sunflower and other row crops. Larvae in the soil orient to the smell of germinating seeds 

There is no known rescue treatment and replanting is required if stand reduction is significant.

Most sunflower seed is now being treated with seed treatments (for example: thiamethoxam (Cruiser)) that should reduce wireworm injury.  However, seed treatments have not been as effective against false wireworms.

Here are two common species of false wireworms in Kansas.

Eulodes

Adult Eleodes suturalis 

Eulodes2

Adult Eleodes tricostata 

FWW

False wireworm larva.

TWW

True wireworm larva.
