Another bad bug to destroy - Leaf-Footed Bug


Today's bad bug to watch for - leaf-footed bug. This particular species is Leptoglossus phyllopus. There aren't high numbers in the garden yet but they are showing up.

If you look at the lower part of his leg there is a big flat/winged spot which looks like a leaf (which is where the common name comes from.) In large numbers they can do a lot of damage just like squash bugs. Unfortunately, leaf-footed bugs aren't specialists like squash bugs and they will feed on tomatoes, bell peppers, egg plant, beans, cucumbers, and squash. They also like blackberry, apple, pears and pecans.

Leaf-footed bugs pierce plant tissue and fruits with their proboscis and suck the juices out. Unfortunately, their saliva injects toxins which do even more damage. And even more unfortunately, these openings create a pathway for secondary pathogens to enter and cause further damage to the fruit and/or plant.

We won't be able to control them on the blackberry bushes or pecan trees but we can control them in the garden. The best thing to do is hand remove them and squish them if you see them to prevent more eggs being laid. Consistent use of an approved insecticide (as in approved for our community garden) will help to control the nymphs and adults.
