Q. We
have a big pomegranate tree that has been doing great for a few years.
Last year we had an infestation of nasty, prehistoric looking large grey bugs
on our pomegranate tree. What can I do to get rid of them?
These bugs had really big thighs, and smaller red ones that look like a cross between a
carpenter ant and a mosquito. This year I noticed the eggs on many
branches and cut them off. I am sure that I missed many and am wondering
what I can do to get rid of them. We have been keeping it organic
up until this point and would love to continue that since we eat as much of the
fruit as possible. Any advice you have would be greatly
appreciated. Thanks so much!!

A. You do not need to cut those branches off. You can just rub them off with a cloth and alcohol or pull leaves off if they are the undersides.
This insect is called the leaffooted plant bug, a close
relative to stinkbugs, squash bug and several others that are pests in home
landscapes and gardens. They get their name from the leaf-like appendage on
their rear legs.

They spend the winter hiding out in landscape trees until
Spring. In the Spring these bugs multiply very rapidly and feed on new soft,
succulent growth from leaves and expanding fruit and nuts. This insect seems to
prefer fruit trees such as pomegranate, almonds and pistachios but can be found
on other plants as well. They are winged so the adults can fly from plant to
plant, tree to tree or landscape to landscape. Their damage to plants includes
leaf damage, leaf drop, fruit damage, fruit drop and nut drop in almond and
pistachio.
a bit of work on your part. Organic sprays would include soap sprays such as
Safers, oils such as Neem and pyrethrin sprays. Organic sprays are usually not
as potent as conventional commercial insecticides so must be used more often
and requires closer monitoring of the plants for buildups in their populations.
Spraying multiple times through the growing season will be required because of
their abilities to build their populations so quickly and their ability for
flight.
Thanks–they are a mess.
They don’t do to much damage on mine. They are part of the ecosystem. If they are not doing damage, as long as you only see a dozen or two, no chemicals are required at all.
