What invasive species of bee was introduced to the US that migrated from Brazil?

The Africanized Honey Bee, often referred to as "killer bees," is the invasive species that was introduced to the United States after migrating from Brazil. In the 1950s, African honey bees were imported to Brazil for research and breeding purposes. However, they escaped and began to hybridize with local European honey bee populations. As they spread northward, they reached the southern United States by the 1980s.

This species is known for its aggressive behavior, higher swarming rates, and adaptability, which allow it to thrive in various climates and conditions, contributing to its expansion across the Americas. The Africanized Honey Bee's characteristics pose challenges for both beekeepers and the general public, making their introduction noteworthy in discussions about biodiversity and invasive species management.

The other choices refer to honey bee varieties that are not invasive or have different origins and characteristics distinct from those of the Africanized Honey Bee.
