Parsnip aphids update
In addtion to willow-carrot aphid (Cavariella aegopodii) and Myzus persicae it is possible that two species of parsnip aphid also transmit viruses to carrot - see Adrian Fox's report for FV 382b.
Of these, so far this year just one Cavariella theobaldi has been caught in the suction traps run by the Rothamsted Insect Survey - at Broom’s Barn on 14thMay - and no Cavariella pastinaceae have been captured so far.
