Pest identification
What's eating my honeydew melon?
Striped cucumber beetle (Acalymma vittatum)
Signs: Adults chew leaves and transmit bacterial wilt; larvae feed on roots, weakening plant vigor.
Control: Row covers until flowering; kaolin clay on foliage; pyrethrin or spinosad spray for heavy infestations.
Aphids (Aphis gossypii — melon aphid)
Signs: Curled, yellowed leaves with sticky honeydew; mosaic virus causes mottled, rugose foliage and reduced yield.
Control: Insecticidal soap or neem oil; reflective mulch deters winged aphids; conserve natural enemy populations.
Squash vine borer (Melittia cucurbitae)
Signs: Sudden crown wilt; frass and entry holes at stem base confirm larval boring.
Control: Monitor with yellow sticky traps for adult moths; wrap stems with foil; apply Bt to base of plant weekly.
Thrips (Frankliniella occidentalis)
Signs: Silver-bronze streaking on leaves and fruit skin; thrips also vector tomato spotted wilt virus.
Control: Apply spinosad or insecticidal soap; use blue sticky traps to monitor; remove weeds that harbor adults.

Honeydew melon pests — FAQ
What is eating my honeydew melon?
Honeydew melon shares the cucurbit pest complex: cucumber beetles vector bacterial wilt, aphids spread mosaic viruses, and squash vine borers kill vines from the inside. Use row covers at transplanting, remove at first flower, and scout daily in warm weather — bacterial wilt can destroy a planting in under a week.
