Explanation:

In argumentative texts such as essays in which the main purpose of the author is to prove his/her position about an issue, the thesis statement or claim is the statement that summarizes the main point of the essay or the position the author has towards an issue or event. This means, the thesis goes beyond a fact or simple opinion and expresses an idea the author will prove.

According to this, in the introduction paragraph included the thesis is "Africanized honeybees are now known as killer bees for several scary but legitimate reasons" because in this sentence the author expresses his opinion toward Africanized honeybees that according to him are legitimately scary and this is the main point he will prove during the essay. Also, other sentences just provide information or facts about these bees but not the position of the author.
