Only with frequent field surveys can these pests be detected and controlled effectively. Flea Beetles Several species of flea beetles attack cole crops in Kentucky. They are very small brown to black beetles that may have some yellow markings on their wing covers. The eggs are laid at the base of the plants. Flea beetles over winter as adults in plant debris in and around the field.
Flea beetles can cause serious damage to seedlings and small plants.
Severe infestations may stunt or even kill young plants. These beetles will jump when disturbed. Larvae are found in the soil and attack roots, but it is the adult feeding that is usually the primary damage. Cutworms Early detection of cutworm infestations means that controls can be applied before serious stand reduction occurs. Eggs are laid by the night flying moths on grasses, weeds, and other host plants.
