White Pupae for Green Fields: How CRISPR Is Transforming Fruit Fly Control

CRISPR gene editing is opening new possibilities for sustainable pest control. A recent study demonstrates how disrupting a single gene—the white pupae (wp) gene—creates visible, stable white-pupae mutants in three major Bactrocera fruit fly species. These mutants make early sex separation easier and more reliable, strengthening the efficiency of Sterile Insect Technique programs. By enabling a cross-species, insecticide-free approach to population suppression, the work marks a significant step toward greener agricultural protection.
