Mutants

Methods & Techniques

• Injected freshly-laid ant eggs with purified Cas9 protein and synthetic guide RNAs targeting the Orco gene.
• Conducted behavioral assays to assess the impact of Orco knockout on ant behavior and reproductive performance.
• Utilized olfactory assays to evaluate sensitivity to semiochemicals in Orco null mutants.
• Analyzed neuroanatomical structures in mutant ants to identify defects in the antennal lobe.

Key Findings

• Homozygous Orco mutants displayed altered behavior, decreased reproductive capacity, and increased mortality.
• Orco null mutants showed reduced sensitivity to olfactory stimuli and unique behaviors such as increased wandering.
• Both studies found significant neuroanatomical defects in the antennal lobe of Orco mutants, indicating a developmental role for the gene.
• The research underscores the importance of olfaction in ant social behavior and adaptation to diverse environments.

Prerequisites

• Evolutionary biology and ecology fundamentals
• Social insect biology and colony organization
