Gall Midges (Cecidomyiidae)
Small flies whose larvae cause galls, blisters or distortion on leaves and shoots.
Gall midges (family Cecidomyiidae) are small flies whose larvae feed within plant tissues, causing galls, blisters, rolled leaves and distorted shoots on many ornamentals and fruit crops. Some species are primarily cosmetic pests, while others weaken plants significantly. Biological control includes generalist predators and, for certain species, specialist parasitoids and entomopathogenic nematodes targeting soil stages, combined with removal of heavily galled tissue.
Biological Controls for Gall Midges (Cecidomyiidae)
The options below are examples of beneficial insects and biological products commonly used against gall midges (cecidomyiidae). Always refer to supplier guidance and product labels for crop safety and local registration status.
Generalist predators including lacewings and mites
Product: Chrysoline + Anderline
Environment: outdoor
Temperature Range: 15.0 – 28.0°C
Rate: Apply according to hot spots on susceptible crops
Frequency: Repeat as monitoring shows activity
Direct biocontrol is limited; predators contribute within a broader IPM strategy.
