Pest identification
What's eating my ridge gourd?
Aphids (Aphis gossypii — cotton/melon aphid)
Signs: Colonies on growing tips; leaf curl, honeydew, and potential mosaic virus transmission
Control: Neem oil or insecticidal soap spray; reflective mulch; encourage natural enemies
Melon fruit fly (Zeugodacus cucurbitae)
Signs: Larvae inside young fruit; oozing puncture wounds; premature fruit drop and rot
Control: Protein bait traps; bag fruits at thumb-size stage; remove and bury infested fallen fruit
Cucumber beetles
Signs: Leaf and flower chewing; bacterial wilt spread causing sudden vine collapse
Control: Row cover at transplanting until bloom; kaolin clay; remove wilted plants to limit wilt spread
Red pumpkin beetle (Aulacophora foveicollis)
Signs: Adult beetles skeletonise cotyledons and young leaves; larvae feed on roots
Control: Hand-pick beetles in early morning; neem-based foliar spray; trap crops of cucurbit seedlings

Ridge Gourd pests — FAQ
What is eating my ridge gourd?
Ridge gourd (Luffa acutangula) is closely related to loofah and shares nearly identical pest pressures. Aphids and fruit flies are the most troublesome in home gardens, particularly in South Asian and tropical climates where this gourd is most commonly grown. Cucumber beetles remain a key vector of bacterial wilt. Powdery mildew-weakened plants attract more insect activity.
