Pest identification
What's eating my goldfinger banana?
Banana weevil / corm borer (Cosmopolites sordidus)
Signs: Larvae hollow out the corm, causing plant wilt, poor bunch development, and susceptibility to secondary pathogens.
Control: Use clean certified suckers; deploy pheromone traps; clear old pseudostem debris promptly after harvest.
Banana aphid (Pentalonia nigronervosa)
Signs: Colonies in leaf sheaths cause leaf curl and honeydew; primary vector of Banana Bunchy Top Virus even on resistant cultivars.
Control: Neem oil or insecticidal soap applied to colonies; rogue out any BBTV-symptomatic plants immediately.
Burrowing nematodes (Radopholus similis)
Signs: Root and corm lesions leading to stunted growth and toppling of plants in sandy or waterlogged soils.
Control: Source nematode-free planting material; hot-water treat corms before replanting; rotate planting sites between cycles.

Goldfinger Banana pests — FAQ
What is eating my goldfinger banana?
Goldfinger (FHIA-01) was bred for Black Sigatoka and Panama disease resistance, but it is not immune to insect pests. Banana weevil remains the chief corm threat, and banana aphids still transmit Bunchy Top Virus. Its improved disease tolerance does reduce fungal pressure, letting growers focus on invertebrate management.
