Emerald green has flying bugs. plant not looking good

othertime(7)February 1, 2012

I have a row of emerald green plants and they are looking thin and are shedding alot. I was out today cleaning up the sheded plant stuff (?) and noticed when I was shaking the tree to get the foilege off the branches a ton of these little fruit fly looking bugs where flying all over the place.

I caught about 6 in a plastic bag and have been looking at them trying to id them but have no clue.

I looked for any larve in the emerald green and did not see anything.

The plant looks like its dying from the inside out and I am wondering if these flying bugs are the cause.

Any ideas????? the bug looks like the size of a fruit fly.

Thanks,

Sam

What part of the country do you have flying insects compromising your Emerald Green... aka Thuja occidentalis'Smaragd'?

It's always a good thing to list in your members page where you live Zone wise. Telling us you live in the USA...well

This is not the time of year for that except in extreme southern areas I suppose.

===>>> nope.. all conifers shed their needles.. mostly between one and three years ... i will yell.. ALL INTERIOR NEEDLE LOSS IS NORMAL... those are the old needles.. and they are shed as the outer green shell starts shading them out ...

and i will yell again.. YOU ARE CORRECT TO CLEAN THEM OUT EVERY YEAR OR TWO ...

as far as i am concerned.. the bugs are irrelevant ... unless you can come up with some actual damage caused by a bug.. rather than normal in interior browning ...

beyond that.. and having no clue where you are.. i too am mystified how they can have bugs this time of year ... unless you are south of the equator .. or on the gulf of Mex ...

they need full sun.. and thinning can be indicative of not enough sun ... more facts in that regard, plz ..

pix and location please..

I am in northern VA, sorry for not putting that up.

I took the bag of bugs to the local garden center and they had a hard time identifying them bcs they were so small. They anitquated them to fruit fly in that they were probably eating up the dying or dead conifer shed as they are organic matter.

I showed them the pics and they said becasue they were topped probably at the wrong time of the year they probably never did recover.

they recomended that they be replace or another shrub be put in its place after removal because they did not think the arborvitae will eventually brown out and die.

I took some pics of the bugs but they are too small to show detail as I do not have a macro lens.

let me upload them when I get home. The bug pictures do not show details because I do not have a macro lens (magnifiying the object).
