Landscape infrastructures are said to provide regulative ecosystem services

Woodlots

Hedgerows

Wildflower strips

Limit nutrient leaching

Wildflower strips are diverse

Ratio Flowers/Grass?

Monospecific or

plurispecific?

Kind of management?

…a diversity of insects

Really?

Crop pests and natural enemies

Pest control

But don’t

necessarily favor

pest control!

…and support…

Why the concept of Functional Diversity may be useful to favor biological pest control?

▪ Between the natural enemies and the floral food
