Enhanced mosquito sex separation using NaCl for optimised sterile insect technique and incompatible insect technique programmes

Year: 2025

Type: article

Abstract: Accurate separation of sexes is pivotal for the success of Sterile Insect Technique (SIT) and Incompatible Insect Technique (IIT) mosquito control programmes. We present a novel approach utilising a 15% sodium chloride (NaCl) treatment coupled with an automated mechanical separation system to significantly reduce female contamination among released males. Our findings not only demonstrated a 30-fold reduction in female contamination rates but also offer insights into the effects of salinity on mosquito larvae and pupae. This integrated strategy enhances the efficiency of large-scale mosquito production for disease control programmes.
