Colossal Biosciences has proposed a genetic strategy to eradicate New World screwworm larvae, recently detected in a calf in South Texas. This method aims to reduce the screwworm population through engineered infertility, potentially safeguarding Texas's cattle industry and economy.
- 01The U.S. Department of Agriculture confirmed the first case of New World screwworm larvae in Texas since 1966, found in a calf.
- 02Colossal Biosciences suggests using gene drive technology to induce infertility in female screwworms, aiming for self-sustaining population control.
- 03The sterile insect technique previously helped control a major screwworm outbreak in Texas, which caused significant livestock losses.
- 04A 12-mile quarantine zone has been established around the infestation site, with strict surveillance measures implemented by authorities.
- 05Immediate action is deemed crucial to prevent the spread of the screwworm, which could have severe economic impacts on the cattle industry.

Colossal Biosciences, a biotechnology company based in Dallas, has proposed a genetic approach to eradicate New World screwworm larvae, which have been detected in South Texas for the first time since 1966. The larvae pose a significant threat to livestock, as they infest and feed on the flesh of warm-blooded animals. The U.S. Department of Agriculture confirmed the detection in a three-week-old calf, prompting immediate preventive measures including a 12-mile quarantine zone. Colossal's strategy involves editing the screwworm's genome to induce female infertility, utilizing a gene drive technique that ensures the trait spreads through the population. This approach is designed to be faster and more cost-effective than traditional methods, which require ongoing releases of sterile males. CEO Ben Lamm emphasized the urgency of addressing the screwworm threat, citing the potential for extensive economic damage if left unchecked. The proposed method aims to create a self-sustaining system that could help control the screwworm population effectively.
