is one of the pests that causes us some problems in our cactus plantings. The adults eat the tops of the leaves, leaving holes here and there. I suspect that they also lay eggs in the plants and this causes the entire plant to die.
I looked at a number of websites that describe this insect pest, here are some of the best….
Bug facts site has a great article on this pest.
OK State University has a short articlethat also shows the insect in its larval stage where it would be described as a white worm or grub. This is the stage where they enter into plants near the ground, and tunneling through cause damage and rot to follow usually killing the entire plant.
The National Sustainable Agriculture Information Service has among the best articles on this little critter.
Yeah, they are a pest alright. And since we are organic, about the only thing we can do is put out sticky traps of yellow. But that would only be a small percentage gain. So we’ve just suffered through it, they are a constant headache, but cause only a small percentage of damage, still, you want all the leaves to be beautiful, but such is never to be. We live in a world in which nearly half the harvest is lost to insects, diseases, animals, mismanagement, theft and confiscation. I guess I’m lucky that all we get is the occasional deer, gopher, ant, scale and cucumber beetle.
