A self-limiting sterile insect technique alternative for Ceratitis capitata.

ABSTRACT:

Background

Genetic biocontrol systems have broad applications in population control of insects implicated in both disease spread and food security. Ceratitis capitata (the Mediterranean fruit fly), a major agricultural pest with a global distribution, is one of the appealing targets for such genetic control.

Results

In this study, we establish and characterise a novel split-CRISPR/Cas9 system we term Sex Conversion Induced by CRISPR (SCIC) in C. capitata. Using the white eye gene for toolkit selection we achieved up to 100% CRISPR/Cas9 efficiency, displaying the feasibility of C. capitata split-CRISPR/Cas9 systems using constitutive promoters. We then induce sex conversion by targeting the transformer gene in a SCIC approach aimed for SIT-mediated releases upon radiation-bas
