Recently we discovered an innovative solution to control *Drosophila suzukii* behavior<fnref n="1" />. Using this knowledge, we started to investigate the possibility to apply this strategy to insects considered as pests, like *Bactrocera oleae* (olive fruit fly) and *Ceratitis capitata* (Mediterranean fruit fly) to modify their social behavior.

## 1. Social interaction

13-19 days old
test during 10 min

*B.oleae* males show less interactions towards females if there is propanoic acid.

## 2. Reversible anesthesia

C.capitata

The time to anesthesia decrease with the increase of concentration of propanoic acid.

C.capitata are more sensitive than B.oleae.

## 3. Diffusion and persistence of the odor

GC-MS using SPME fiber
Exposure time : 10 min
10% of each acid

In a closed environment, the diffusor release slowly the odor.

After removing the diffusor, acids are still detected.

This new technology<fnref n="2" /> could be interesting to avoid infestation of fruits by limiting egg laying and population propagation while respecting the environment.
