The Culex quinquefasciatus Johannesburg strain genome sequence is a joint effort between the Broad Institute and the J. Craig Venter Institute (JCVI). Assembly of 8x shotgun coverage was performed using the Broad's whole genome assembly package ARACHNE. The assembly presented here (CpipJ2, April 2014) consists of 3,172 scaffolds, totalling 580 Mb.

The assembly differs from the previous version by the addition of the mitochondrial genome (GU188856, 15,587 bp) which includes 13 protein-coding and 24 ncRNAs (tRNAs and rRNAs).

The Johannesburg (JHB) strain is the source of genomic DNA for the Culex quinquefasciatus genome project. This strain has been selected because it consistently yields high quality chromosome spreads suitable for in situ hybridization studies. This strain is also insecticide susceptible and so can be transported and maintained in laboratories world-wide. The Johannesburg (JHB) strain was established from offspring reared from 20 egg rafts collected in a single unused fish pond in March 2001. Population genetic studies revealed that the Johannesburg C.
