Pest identification
What's eating my burpless cucumber?
Striped & spotted cucumber beetle
Signs: Leaf, flower, and root feeding; bacterial wilt transmission causes sudden vine collapse.
Control: Row cover until flowers open; remove promptly for bee access; pyrethrins or kaolin clay spray on adults.
Glasshouse whitefly
Signs: Clouds of tiny white insects under leaves; honeydew coats foliage and fruit, promoting black sooty mould.
Control: Introduce parasitic wasp Encarsia formosa early in the season; yellow sticky traps to monitor; insecticidal soap spray on nymphs.
Two-spotted spider mite
Signs: Pale stippling and fine webbing on leaf undersides; plants weaken rapidly in dry, hot spells.
Control: Mist foliage to raise humidity; release Phytoseiulus persimilis under glass; avoid broad-spectrum insecticides that kill natural enemies.
Aphids
Signs: Soft colonies on shoot tips; honeydew, distorted leaves, and virus risk.
Control: Encourage aphid predators; reflective mulch deters winged adults; insecticidal soap or neem oil for heavy infestations.
