Impact of native vegetation on the flight of aphids

Plain text source: 
Less aphids are found flying in crops close to native vegetation.. Aphids can vector viruses that lead to yield loss in crops eg BYDV in cereals can decrease crop yields by 50%if plants are infected prior to tillering; or cause direct feeding damage which can cause yield losses of up to 10% in cereals (DAFWA 2007)... Significantly more (p<0.001) brassica aphids were found in traps that were close to native vegetation whereas traps that were far from native vegetation had significantly (p>0.001) higher numbers of legume aphids and aphids whose hosts were unknown...
