Comparative chemosensory genomics of stored product insects

On-Demand
On-Demand
Stored product insects from diverse taxonomic lineages evolved to exploit amylaceous commodities and respond to similar food volatiles in the lab and under field conditions.  Through the USDA ARS Ag100Pest initiative, the genomes of 10 stored product insects have been assembled to chromosome scale and another 8 are slated for sequencing.  These genomes can be used to identify convergent adaptations used by these insects to locate food resources.  Of particular interest are whether there are convergent adaptations in the amino acid sequences and and substrate binding sites of chemosensory genes that allow these diverse groups of insects to perceive and respond to the same food volatiles.
