What pest is the US Government planning to breed at a South Texas factory?

The correct response indicates that the US government plans to breed sterile flies. This approach is part of a broader pest management strategy known as the Sterile Insect Technique (SIT). The method involves releasing sterilized male flies into the wild, where they mate with females. Since the females mate with sterilized males, no offspring are produced, which helps control the pest population over time.

Using sterile flies is particularly effective because it can reduce reliance on chemical pesticides, which may have harmful environmental and health impacts. This technique has been successfully implemented in various pest control programs, including those aimed at controlling agricultural pests that threaten crops and reduce economic loss.

The other options do not align with this specific pest management approach. Common flies, fruit flies, and house flies are all varieties of pests that may pose issues, but the targeted strategy in this case focuses on breeding sterile flies to effectively manage and reduce their populations without resorting to more harmful methods.
