Answer 1

The Africanized bee, also known as the Africanised honey bee, and known colloquially as "killer bee", is a hybrid of the western honey bee species (Apis mellifera), produced originally by cross-breeding of the East African lowland honey bee(A. m. scutellata) with various European honey bees such as the Italian honey bee A. m. ligustica and the Iberian honey bee A. m. iberiensis.

The Africanized honey bee was first introduced to Brazil in 1956 in an effort to increase honey production, but 26 swarms escaped quarantine in 1957. Since then, the species has spread throughout South America and arrived in North America in 1985. Hives were found in South Texas of the United States in 1990.[1]

Africanized bees are typically much more defensive than other species of bee, and react to disturbances faster than European honey bees. They can chase a person a quarter of a mile (400 m); they have killed some 1,000 humans, with victims receiving ten times more stings than from European honey bees. They have also killed horses and other animals.

Answer 2

The tectum refers to the "Roof" of the midbrain, an anatomical area that consists of the superior and inferior colliculi. If you slice the midbrain transversely it is the area dorsal to the cerebral aqueduct.
