Hello Gerry,

Finally I think you are right for Cacopsylla mali is the only one hosted by Malus in Canada.

Thank your help...

You know, there are so much errors on the web that I don't want my website contributes to those identification errors. That's why I preferred usually to stay safe with identification and that's why I usually do cross-reference identification in order to be assured of it (if you understand what I mean). So please, don't subscribe to different forums under different names in order to confirm an identification

Cheers,

Michel
