You're talking about The Swarm (1978), which is absolutely so-bad-it's-good. Fans of Michael Caine will I think in particular find it rewarding, and I was especially impressed with its frankly prescient treatment of the drawbacks inherent in mass insecticide application given that the ongoing research increasingly points to exactly that as the culprit for pollinators disappearing.
That said, my understanding is that A. m. scutellata x A. mellifera hybrids aren't unusually aggressive in nest defense by the standards of social hymenopterans generally, but only by the standard of the European honeybee (A. mellifera). I can't claim close familiarity with the relevant literature on bee hybrids, but from what I have seen, their nest defense behavior seems roughly comparable in aggressiveness to that of many yellowjacket (Vespula, Dolichovespula) species. On the other hand, a wild bee colony is likely to be one or two orders of magnitude greater in size than a wild yellowjacket colony, which means that a comparable level of aggression in nest defense could pose a significantly greater hazard.
Using the figures from the Wikipedia article [1] and its relevant source [2], it looks like A. m. scutellata x A. mellifera are responsible for an average of around 15 human deaths per year since the introduction of A. m. scutellata into Brazil in 1956. So I don't really see that there's very much to worry over here, in any case.
Are you? They attack rarely (although are thought to have done so fatally a few weeks ago here in NZ) and aren’t even seen usually, but they are close to popular beaches.

Given that the shark attack stats cover a period 25 times as long as that for the bees, wasps, and hornets, I do feel like "considerably" is a fair choice of adjective here.

Probably people die of bee stings more than sharks attacks here in NZ, but those bees certainly aren’t africanised. I suspect most US deaths aren’t all from africanised bees either but that’s going to be hard to prove.
That's only the specimens that have been sequenced and archived at BOLD. That doesn't include the various other bee families, notably Halictidae, Colletidae, Melittidae, and others roughly all the "sister groups" in the Apoidea [1].
An example of why is this important? The Africanized honeybee, known perhaps from bad horror movies, is characterized (identified) as a hybrid of two species. It can be more or less aggressive (to the point of killing you if you don't GTFO) depending on then nature of its DNA. Hybridization has blurred the limits of the species in many areas, including in the US. Sequencing specimens is the only way to confidently determine which of the species you have, A (friendly bee honey), AB (grumpy bee honey), or B (deadly bee honey) (gross simplification here, not Mendelian).
