We also showed that a chemical fraction of the resistant strawberry accession that contains methyl anthranilate carries some activity toward the egg hatching rate. We found that methyl anthranilate alone triggers embryo lethality in a concentration-dependent manner, unlike another comparable organic fruit compound. We first noted that one of the more resistant accessions showed an unusual enrichment of methyl anthranilate within its fruit, prompting us to investigate this fruit compound as a possible cause limiting fly development. In the present study, we aimed at understanding the chemical basis of this effect. We identified several accessions that significantly reduced adult fly emergence from infested fruit. suzukii eggs, in the search of natural resistance. In a previous study, we investigated the impact of different strawberry accessions on the development of D. During the past decade, Drosophila suzukii has established itself as a global invasive fruit pest, enabled by its ability to lay eggs into fresh, ripening fruit.
