Agave Snout Weevil
The adult weevil attacks many species of agave.
Agave Americana or century plant is more
susceptible to weevil damage than the smaller species.
DESCRIPTION OF THE PEST
The adult weevil is about ½ inch (12 mm)
in length, is brownish black and has a dull
body .The adult female enters the base of the plant
to lay eggs.
Symptoms and damage
Decay microbes also enter through this injury
and as the tissue rots,
the plant has a wilted appearance. Infested
plants soon collapse and die.The
larvae (grubs) develop in the dying plant and infect other hosts
nearby. Agave snout weevil also infests the
canes of several Yucca
Control of the agave snout weevil is difficult.
Selecting species that are less susceptible and
typically smaller than the century plant is helpful, especially in areas where
has occurred previously. With rare or special
specimens, chemical prevention using a broad-spectrum insecticide applied in
spring is often effective in reducing damage.
