Yellow fever mosquito (Aedes aegypti)
Aedes aegypti, the yellow fever mosquito, is a mosquito that can spread dengue fever, chikungunya, Zika fever, Mayaro and yellow fever viruses, and other disease agents. This mosquito originated in Africa, but is now found in tropical, subtropical and temperate regions throughout the world. Read more about yellow fever mosquitoes on WHO website.

Chromosome-length genome assembly
Download the AaegL4.fasta.gz file containing the chromosome-length (2n=6) assembly of the yellow fever mosquito genome. All modifications with respect to the draft (see below) are annotated in the AaegL4.assembly file. Some basic stats associated with the new reference, AaegL4, are listed below. The full data release can be explored here. Note that chromosome-length genome assembly based on another draft is available for this species, here.

Method
3D Assembly was performed using 3D-DNA pipeline (Dudchenko et al., Science, 2017). The genome was reviewed using Juicebox Assembly Tools (Dudchenko et al., bioRxiv, 2018). See Methods for more information.
Hi-C sample
The sample for in situ Hi-C preparation was donated by a female individual, and obtained from Benzon Research.
Hi-C Contact maps
Hi-C data was aligned to the draft reference using Juicer (Durand, Shamim et al., Cell Systems, 2016), and contact maps visualizing the alignments with respect to the draft and the new reference were built using 3D-DNA (Dudchenko et al., Science, 2017). The contact maps can be explored below via Juicebox.js interactive tool (Robinson et al., Cell Systems, 2018). To explore the assembly in greater detail, please download the .hic and .assembly files from the data release folder and use Juicebox Assembly Tools (Dudchenko et al., bioRxiv, 2018).
