This section contains pests of landscape plants only. Adult agave weevils don't have wings, so they move from plant to plant by walking on the ground. Larvae are similar to white grubs except they are legless. The adults chew into the leaves and introduce a bacterial rot that appears to be necessary for larval development. They lay eggs into the holes and the larvae burrow into the plant.
Infested plants exhibit wilting and wrinkled leaves, and quickly decline due to the bacteria.
Remove and destroy plants as soon as damage is evident. Remove larvae and adults from soil around where the plant was removed. Their head tapers forward into a short, broad snout. They are generally brown or black with a fine covering of white hairs over the wings and body. They do not consume foliage, but several species lay eggs on the seed pods of honey mesquite and other mesquites.
