Cabbage maggotRadishInsectThe cabbage maggot is the larvae of a gray fly that is about 3/16" long. Females lay eggs near the base of plants such as cabbage, broccoli, cauliflower, radish, and turnip. The white larvae make tunnels and grooves in the roots and underground portions of stems. Soft rots often infect these areas, causing further damage. The leaves of affected plants are often yellow and stunted. Severe damage can result in wilting and death of plants. Younger plants are more severely damaged. Mature larvae can be up to 3/8" long. They pupate in the soil, with up to three generations occurring in a season. The last generation of the season overwinters in the soil, hatching into adults in early spring.
