April 20, 2018

The first edition of AHDB Aphid News for 2018 has just been released:

The switch from weekly to daily suction-trapping commenced on 5 March, before that catches were weekly.
The sudden change in weather, including the upturn in air temperature this calendar week, has prompted the beginning of this year’s aphid reporting.
No peach–potato aphids (Myzus persicae) or willow-carrot aphids (Cavariella aegopodii) have been caught so far this year.
The shallot aphid (Myzus ascalonicus) is the most numerous aphid species in the suction-trap samples to date and has been caught in all of the traps from Kirton south.
