Evidence

Peer-reviewed

Geography

Global agroecosystem literature; conservation biological control

System

Agricultural pest–predator networks; semiochemical signaling

## WHAT THE EVIDENCE SAYS

A review of conservation biological control describes how plant, herbivore, parasitoid and predator chemical signals might aid pest suppression. It stresses that odors, weather, crop phenology and multi-species interactions often disrupt the behavior seen in simplified trials. Authors call for field measures linking natural-enemy recruitment to predation and reductions in actual crop damage.

## WHY IT MATTERS / OUR READ

An increase in beneficial-insect attraction is an intermediate response, not yet an agricultural or ecological success. Pairing habitat manipulation with monitoring of prey/pest populations and non-target effects is essential.

## CAVEATS / UNCERTAINTY

This review offers a research assessment rather than measured effectiveness of a particular field intervention. The online accepted version was accessible ahead of final journal formatting.
