In 2014 south eastern Australia experienced the right conditions for the growth of green peach aphid (GPA) leading to significant spread of the Beet western yellows virus (BWYV) in canola. These presentations on BWYV in canola and GPA were given at Wagga Wagga, NSW 5 August 2014 by NSW Department of Primary Industries staff. See the take home messages or jump to your topic of interest.

BWYV take home messages
Don presents questions and considerations for monitoring and spraying GPA and potential yield impacts of BWYV. He also discusses management precautions for next season including monitoring, seed treatment and insecticide applications.
Background to the BWYV issue in 2014
Don talks about conditions for development, dates BWYV was detected and shows pictures of GPA feeding damage.
Green peach aphid identification and life cycle
Dr Jo Holloway
Jo’s presentation will assist in continuing to monitor aphid populations by describing GPA, cabbage and turnip aphids. Aphid lifecycles, reproduction and development and habitat are outlined. Jo also describes the ecological and agronomic conditions that led to the current outbreak.
