Pepper Insect Pests
Leaves are distorted, stunted, and often curled under. The
upper leaf surface is sticky and has a black moldy growth
(sooty mold). The plants have fewer frutis than usual. Some
wilting may also be evident.
Piercing-sucking mouthparts. These are small pear-shaped
insects with prominent reddish eyes. They vary in color from
yellow to green to black. Some have transparent wings.
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 will see adults
and young living and feeding together.
The cotton aphid has continual generations and many
different hosts. When populations on the host plant are high,
winged forms are produced, and they 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 as 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.
