Where To Look
Select leaves that are beginning to curl under or have signs
of black sooty mold on the upper surface. Turn them over
and look for groups of variable-sized insects. You should
see adults and young living and feeding together.
Aphids on leaves
The cotton aphid has continual generations and many different host. When populations
on the host plant are high, winged forms are produced, and these fly to adjacent plants
to establish new colonies. Aphid colonies are commonly visited by ants which feed on
the honeydew secreted by the aphids. This honeydew also serves ad the food on which
the sooty mold grows. The cotton aphid is a virus vector and has a wide host range
including many vegetable crops.
