  • The number of cereal aphids caught in Rokeby suction trap (blue line) between the 17th and 23rd of November 2020 (Nov Week 4) was 25 and is displayed in the graph below, along with;

                -  Other aphid numbers for 2020 (orange line)

              - Average weekly temperature s for 2020 (purple line), calculated  from mean daily temperatures from NIWA CliFlo data for Ashburton (station no.26170) and

            - The 10-year average of weekly temperature between 2010 and  2019 (red line)

                -  4 year average of cereal aphid numbers  for Rokeby (green line)

Cereal aphid numbers caught in suction traps are an indication of flights and do not replace the need for direct searching and monitoring in your crop.

Relatively high numbers of aphids are expected till the end of May, with spring flights occurring late September or October

Generally the warmer the temperature, the faster an aphid will develop into an adult. However other factors, such as amount of rain, can affect aphid development and survival.
