Saddle gall midge larvae on the move

HGCA has received areport of relatively high numbers of newly hatched saddle gall midge larvae ata site in Suffolk.

The sightingdemonstrates how pest pressure from saddle gall midge is often localised andsporadic as HGCA survey data of trapped adults in late May/early June atmonitoring sites in Buckinghamshire and North Yorkshire were shown to berelatively low.

Typically, blood-redeggs hatch around 1-2 weeks after being laid and the larvae travel down theleaves to feed on the stem underneath the leaf sheath and characteristicsaddle-shaped galls form.

When larvae are young,as spotted in Suffolk, they are small and white and not easy to see but willgrow to 4-5mm and gradually turn red.

Over the last fewyears, saddle gall midge has been mainly reported in central England. Growerswho suspect that this pest is present on their farms are being urged to consultHGCA Information Sheet 15 Biologyand control of saddle gall midge for further information.
