Successful implementation of the sterile insect technique (SIT) against Aedes albopictus and Anopheles arabiensis relies on a continuous supply of sterile males. To meet this requirement, optimization of the mass-rearing techniques is needed. This study, therefore, aims to assess a new mass-rearing cage (MRC) in terms of egg production efficiency and egg hatch rate (quality).
A paper that appeared in Scientific Reports by Evans et al. (1)asked whether changes in the genotypes of target mosquito populations would occur due to introgression of released transgenic mosquito genomes. The paper in fact describes the introgression of released mosquito strain genome into wild populations of Aedes aegypti after releases of the OX513A strain developed by Oxitec and the paper has generated a lot of controversy. Is this a surprising finding or an entirely predictable outcome? Is it cause for alarm?
