Guess The Pest! Week 3 Answer: Seedcorn Maggot

David Owens, Extension Entomologist, owensd@udel.edu

I admit, I’m not sure what happened to my form. I know I updated it, but must not have hit the submit button. The beans in the photo are being attacked by seedcorn maggot. The rest of the photo is pretty clear what is going on. Affected seedlings often have a swollen stem where the maggots are trying to burrow in. These beans were planted in a field we purposefully have baited to attract flies by incorporating fallow weeds and chicken manure at 360 degree days (base 39) and spreading bone and meat meal over the plot at planting.
