Description

Assess the occurrence and infestation rate of olive flies, olive beetles, olive lace bug and their parasitoids in wild and domestic olives in the Western Cape and to generate primary DNA sequence data. The data will include estimates of genetic diversity in olive flies, novel complete mitochondrial genomes and sequences for barcoding in six species.

Sampling Description

Study Extent

Western Cape, Stellenbosch

Sampling

Whole animals where collected

Method steps

We propose to survey the presence, estimate infestation rate in wild and domestic olives and assess the genetic diversity of B. oleae and B. bigutulla, Argopistes spp. (A. sexvitattus, A. capensis and A. oleae) and P. australis (olive flies, olive beetles and olive lace bug, respectively) in the Western Cape of South Africa. We will generate primary sequence data on complete mitochondrial genomes for one individual of each species, and cytochrome c oxidase I (COI, the reference barcoding DNA region) for 50 individuals of each species. Complete mitogenomes will be used to reconstruct phylogenetic trees of Bactrocera spp., the Galerucinae sub-family for Argopistes spp. and the Tingidae family for Plerochila australis. Novel COI data will be generated and deposited in BOLD for barcoding purposes, accompanied by full taxonomic records. Complete mitogenomes, COI and mtDNA polymorphic regions will be used to assess intra-specific diversity in olive flies.
