This paper compares the results obtained when analysing the population density of the Mediterranean fruit fly (Ceratitis capitata [Wiedemann]) by standard methods and kriging interpolation. The data used were collected during a pest control experiment involving mass trapping of the females of this species in a citrus orchard. These captures provided a series of diagrams showing the heterogeneous spatial distribution of the flies. Since trapping began at the end of June, the insects were first caught preferentially in trees at the western and southern borders of the orchard. As the number of flies grew the rest of the crop was invaded. Kriging provided information that would allow more efficient pest management by focusing control efforts on areas where target populations are at their largest. |

Approximately 80% of the world's cattle are raised in regions with a high risk of tick-borne diseases, resulting in significant economic losses due to parasitism by Rhipicephalus(Boophilus)microplus. However, the lack of a systemic biology approach hampers a comprehensive understanding of tick-host interactions that mediate tick resistance phenotypes. Here, we conducted a genome-wide association study (GWAS) of 2933 Braford cattle and found 340 single-nucleotide polymorphisms (SNPs) associated with tick counts. Gene expression analyses were performed on skin samples obtained from previously tick-exposed heifers with extremely high or low estimated breeding values for R.microplus counts. Evaluations were performed both before and after artificial infestation with ticks. Differentially expressed genes were found within 1-Mb windows centered at significant SNPs from GWAS. A total of 330 genes were related to the breakdown of homeostasis that was induced by larval attachment to bovine skin. Enrichment analysis pointed to a key role of proteolysis and signal transduction via JAK/STAT, NFKB and WNT/beta catenin signaling pathways. Integrative analysis on matrixEQTL revealed two cis-eQTLs and four significant SNPs in the genes peptidylargininedeiminasetypeIV (PADI4) and LOC11449251. The integration of genomic data from QTL maps and transcriptome analyses has identified a set of twelve key genes that show significant associations with tick loads. These genes could be key candidates to improve the accuracy of genomic predictions for tick resistance in Braford cattle.
