The behavioral effect of 4 mixtures volatile organic compounds tested separately is evaluated on Cydia pomonella codling moth larvae. The average attractiveness of the neonate larvae of codling moth varies according to the mixtures tested; it decreases proportionally with the increase of the doses used and the duration of experimentation. This study shows that neonate larvae have a preference between the tested mixtures, it shows an attractiveness for both mixture B and D, but seem less attractive by mixtures A and C. Variance analysis with two classification criteria revealed no significant differences for the organic compounds factor and significant differences for the dose factor. The test of Newman and Keuls at the threshold of 5% highlights two homogeneous groups: A and B
Cydia pomonella, Volatile organic compounds, Behavior, Attractiveness
