Yes Ammar this is typically larva of some species belonging to Curculionidae family but could be any species from this photo it is impossible to determined because of more similarities between species larvae

Dear Manole,

Thank you very much for the helpful info,

Best regards,

Better if you had larva alive it is very easy to let it grow and pupate and you could obtain the adult which will be more easy to identified

Let me guess this is the larva of Bostrichidae gen. sp. (Coleoptera)

Bostrichidae, with few doubts.

I think it is Coleopteran larva

Is a Curculionidae: Scolytinae larva. There are several reports of black timber bark beetles pests of Malus silvestris in Europe  like Xylosandrus germanus and Xylosandrus crassiusculus. You must check with the adult to confirm. It is not Bostrichidae.   Bostrichidae larva are elongated with  the Prothorax typically more enlarged than either meso- or metathorax.

Dear All,

Thank you very much for your info related to my question,

Best regards,

Ammar

Dear Ammar,

Considering the amount of larvae in your piece of Malus, I'm almost certain there must be some adults in it. That would be of great help to get a species-level identification.
