two different "banana" spiders
You must be talking about Nephila clavipes, which is a very large garden orb weaver that is completely harmless. They're commonly referred to as banana spiders. I have no idea why.
It's unlikely that this spider would be found in a fruit box, as they just hang out on their webs and don't get out much.
The "banana" spider in the article is very likely to be a Phoneutria sp., which is sometimes called banana spider because it's so often found in banana shipping boxes. The phoneutria spiders don't make webs, and they like a warm and dry place to hang out. The shacks where banana growers leave the bananas to ripen is the ideal place.
