Book Description
Excerpt from The Plant Disease Reporter, 1949: Supplements 180-188 During winds the aphids do not fly, winged aphids remaining on the plants until the wind dies down. After the wind has abated and condi tions become right, they take off in swarms and move across the country. Flight appears to be at random, and the insects are carried by the air drift which usually amounts to one to two miles per hour.
