Aphid Winged Alates
Winged dispersal stage of many aphid species often seen colonising new crops.
Winged alate aphids are the dispersal stage of many aphid species. They arrive in flushes on new plantings or at vents and doorways, where they start new colonies. They are important virus vectors. Monitoring with yellow sticky traps and targeted banker plant systems helps intercept alates early, while parasitoids and predators then manage the resulting colonies.
Biological Controls for Aphid Winged Alates
The species below are examples of beneficial organisms commonly used against aphid winged alates. Recommendations are based on published biological control information and practical IPM experience. Always confirm suitability for your crop, growing system and local conditions before use.
Aphidius colemani
Environment: glasshouse
Temperature Range: 12.0 – 28.0°C
Rate: 0.25–1 wasp/m², ahead of expected flights
Frequency: Introduce weekly during risk period
Preventative parasitoid to intercept colonising winged aphids; combine with exclusion netting and monitoring.
