Found the answer

Adjective designating any living organism favourable to Man's activities.
Beneficial organisms include natural enemies of pests, agents of biological control, natural or reared pollinators (bumble bees, bees), which pollinate numerous plants, earthworms (Lumbricids) and all animals and micro-organisms which contribute to soil fertility.

So I will close but thank those who tried to help me.

i've just half found the answer;

It's "auxiliaires des cultures"

Les auxiliaires sont des ennemis naturels des ravageurs des cultures. Ce sont des prédateurs, des parasites, ou encore des agents de certaines maladies qui détruisent les nuisibles.

So I just have to find the English for this now

Imo using a thesaurus could prove helpful in finding all the alternatives in English

Hello

In the first sentence where I'm stuck, they are talking about species.
I just can't see how this can be "rodents, trees, auxiliary products"

But you are probably right in the second sentence. It would work there
