Other claims from this paper (12)

Intervention effect A. pullulans significantly repelled B. oleae females and induced a distinct VOC profile.
Intervention effect B. amyloliquefaciens significantly repelled B. oleae females and induced a distinct VOC profile.
Intervention effect Alcaligenes faecalis treatment had higher alkene levels including o-cymene and d-limonene.
Intervention effect B. amyloliquefaciens treatment had higher alkene levels including o-cymene and d-limonene.
Intervention effect P. commune induced alkane emission.
Intervention effect A. pullulans induced alkane emission.
Association Six VOCs negatively correlated with fly entries; beta-myrcene was most prominent, followed by d-limonene, o-cymene and 5-octadecene (E).
Association Repellent VOCs were positively correlated with each other.
Mechanism Combined repellent-VOC emission may produce synergistic repellency.
Association 1, 4-hexadiene, 5-methyl-3-(1-methyl ethylidene) was an attractant positively correlated with fly entries.
Mechanism The attractant appeared to originate from biosynthetic pathways different from those producing repellent VOCs.
Recommendation Three endophytes and combined repellent VOCs were identified as promising sustainable olive-fruit-fly management strategies.
