TLDR
The results might indicate the length of time elapsed since B. oleae became established in the Mediterranean region, the large effective sizes expected of its populations and the high gene flow among Iberian populations.Abstract:
The tephritid Bactrocera oleae (Gmelin) is a harmful pest of olive crops that cause important agricultural and economic losses in the Mediterranean area where 90% of the world olive trees are cultivated. The knowledge of the genetic diversity in insect pest species populations is critical for decisions concerning appropriate control management strategies. In the present work, the genetic variability within and among 7 populations -five from Spain, one from Italy and one from Tunisia-, was assessed by sequencing 1151 bp of the COI gene. A total of 21 haplotypes were observed. The intraspecific diversity was high, particularly in the Spanish populations (haplotype and nucleotide diversity 0.84 and 0.00137, respectively). However, the genetic differentiation among the populations was low in the case of Spanish ones (Fst between 0 and 0.041), and higher –and statistically significant– when comparing with the Italian and Tunisian samples. The haplotypes distribution and the PCoA analysis show three clear groups of populations: Spanish, Italian and Tunisian. The results might indicate the length of time elapsed since B. oleae became established in the Mediterranean region, the large effective sizes expected of its populations and the high gene flow among Iberian populations. The information could be relevant for integrated control programmes coordination.read more

TL;DR: Several of the most toxic crystalliferous isolates may contain novel toxins since they gave no PCR products when probed with primers specified for 39 known toxin genes.

TL;DR: Pupae suppression reached the maximum value in the beginning of spring and these results indicate that soil arthropods have strong impact in the decline of B. oleae pupae in olive groves.

Bactrocera oleae (Diptera: Tephritidae) in Iran: An invasion from the Middle West
TL;DR: Genetic analyses of mitochondrial markers of B. oleae collected in the traditional olive growing area in Northwestern Iran were used to determine the origin of this pest, and results indicate it was most likely imported on olive trees from the Central Mediterranean area.

Bactrocera oleae (Diptera: Tephritidae) organophosphate resistance alleles in Iberia: Recent expansion and variable frequencies
TL;DR: Resistance-associated Ace alleles were found to have become widespread in both Western and Southern Iberia, but with highly varying frequencies, which is consistent with previous sug- gestions of a recent, selection-driven spread and has implications for the importance of Ace mutations in organophosphate resistance in the field as well as the important of gene flow between Mediterranean populations of B. oleae.

TL;DR: This work recovered 202 haplotypes from the current sampling and updated previously published work to reveal a total of 231 haplotypes for this pest, showing that two of the haplotypes were private to SIT flies, not present among wild fly collections.

Estimation of levels of gene flow from DNA sequence data.
TL;DR: It is found that in general when there is no recombination, the cladistic method performed better than FST while the reverse was true for rates of recombination similar to those found in eukaryotic nuclear genes, although FST performed better for all recombination rates for very low levels of migration.
