|Palestriped Flea Beetle|
|Damaging stages:||Grubs on roots, adults on cotyledons and foliage|
Palestriped Flea Beetles are a pest of many food crops, and can also cause damage to ornamentals, particularly when the host plants are young.
Description[edit | edit source]
Adult beetle is yellow through brown or black with a paler stripe on each wing cover, and a red head. Like all Flea Beetles, they jump away when disturbed. Grubs are long and thin.
Symptoms and Signs[edit | edit source]
Grubs cause root damage, particularly to tubers such as potatoes or sweet potatoes. Adults cause shotholing or skeletonized leaves, particularly of young plants.
Ecology[edit | edit source]
Overwinters as an adult in debris.

Control[edit | edit source]
- Cultural controls: Suppress weed hosts, clean growing area in the autumn or winter, disking fields
- Physical removal: Vacuuming
- Barriers: Row Covers
- Pesticides: Carbaryl, Pifenthrin, Permethrin
- Organic pesticides: Rotenone, Spinosad
- Timing: Planting crops later in the season can help avoid seedling damage.
