"Research indicates that aphids flying over plants with orange or yellow
flowers do not stop, nor do they prey on plants growing next to or above
the flowers[201]. "

So could one protect crops from aphids by putting out plastic flowers?
(which might be more convenient)


I've seen aphids on yellow and orange roses and yellow honeysuckle, and
stuck on those bright yellow sticky insect trap-cards. That suggests to
me that the colour is not an aphid deterrent.
