banana tree is the 4th largest crop in DRC and it is extremely important to
take care of the tree when it is growing. The weevil is a black insect with a
long nose. It is about the length of the nail on your small finger. It slows
down the growth of the banana tree by burrowing into the trunk and laying its
eggs. The young weevils damage the structure of the banana tree. You can see
many small holes at the base of the tree between the roots and the collar, and
sometimes underground. These holes weaken the tree, and it can even sometimes
come crashing down. Also, the holes are entry points for secondary infections
that can kill the tree
live in the earth and like humid spots to lay their eggs. They can reach very
high numbers in the rainy season.
trapping helps to reduce the numbers of weevils in the field that are
attempting to lay eggs in the tree by attracting them to a humid and fresh environment.
Fewer eggs will be layed in the healthy trees.
the field every two to three days very early in the morning, or late at
night. Do this from when you plant the seeds or seedlings until production. If
you see some weevils near banana trees after digging around, or you already
see some holes near the collar or near the roots at the base of the trunk:
- Take a stem of an old banana tree (still fresh) that has already
- Cut the stem to about the length of your arm. Cut this piece into
- Place them, face down near the infected banana tree, or in a ring
around infected banana trees
one trap (composed of two pieces) around the infested banana trees and
protect the other trees that are not affected by surrounding the affected
zone with traps.
the field every morning thereafter to check on the traps. Once the trap has
dried up, or if the weevils are burrowing into them, take them out of the
field and burn them. Replace the traps until the end of the production
