Both species are non-native pests introduced by human transport from East Asia. Based on the biological control test bot...

Re: Is this bamboo mite?

It doesn’t seem to be the widespread bamboo mite Stigmaeopsis nanjingensis. In Europe we have another bamboo mite, called Schizotetranychus bambusae. May be it’s Schizotetranychus bambusae. Please see the picture in this Dutch publication (scroll to the end!). https://kmdoc.naktuinbouw.nl/Datasheets...

Re: Turning Black with Sticky hairs

Thank you - Glen! You are right. In the following reliable report I found a picture of Antonina pretiosa with its long anal wax tube (Page 80, picture 11):

Re: What are they and how do I get rid of them?

thinking they may be armoured scale I don't feel certain, that it is the scale insect Kuwanaspis pseudoleucaspis . Nevertheless i sent you a link regarding this common bamboo pest (see page 78, left column): http://www.acta-zoologica-bulgarica.eu/downloads/acta-zoologica-bulgarica/2014/supplement-6...

Re: Fargesia pest ID help.

In Europe we have the Asian leaf mining fly Cerodontha unisetiorbita on bamboo, but the leaf mines are looking somewhat different:

Please find a pupa of the culprit. Try to get an insect from the pupa.

Re: Bamboo Leaf Miner Fly

Luciano Süss discovered the mining fly in the year 2000 in Italy. He wrote that the bamboo coped very well with the damage. After the year 2000 he didn't find the fly any more in Italy (personal communication 2014). Rai John, did you see my detailed report on the homepage of the EBS? http://forum.ba...

"Fortunately the fly causes no noteworthy damage. So it will not be necessary to combat the pest. Rai"

By that Rai, do you mean the fly damage is unnoticeable but the subsequent pupa damage is?
