Phyllotreta striolata

Striped flea beetle (Phyllotreta striolata)
Latin Name Phyllotreta striolata
Common Name Striped flea beetle
Biology

Adults are ~2 mm, black with yellow stripes. Larvae feed on roots. Multiple generations/year. Overwinters as adults. Jumps when disturbed .

Damage

Adults skeletonize leaves; larvae damage roots. Affects crucifers (e.g., cabbage, radish), causing yield loss .

Distribution Regions

Cosmopolitan in temperate/tropical regions (e.g., Asia, Europe, North America) .

Monitoring

Visual inspection of leaf damage. Yellow sticky traps. Soil sampling for larvae .

Recommended Traps

Yellow sticky traps. Pheromone traps (e.g., isothiocyanate lures) .

Literature review

Semiochemical evidence

The cited publications support the exact compound-species relationship. Formulation, ratio, loading, release rate and field lifetime depend on a validated lure protocol and are not inferred here.
