We next compared how this innervation pattern relates to that of DA2-PNs conveying information from another highly repellent olfactory pathway mediating odor information regarding the presence of detrimental microbes [ 40 ]. Figure Explanation of the different results from reciprocal crosses between red-eyed red and white-eyed white Drosophila eye color sex linked in Mount Gambier.

This phenotypic difference is determined by two alleles of a gene located on the differential region of the X chromosome. It therefore remains unclear why Drosophila larvae do not express Or85f, and by that are restricted to detect iridomyrmecin only. Although the amount of active odor within the headspace was too low to be visible in the GC trace, a repeatable and strong response was elicited from the ab10B OSN at a specific GC retention time.
