I like sci-fi. I’m not your typical Star-Wars nerd, instead I like B-movies. You know… the low-budget creature feature movies that entail some giant creature killing everything in sight? They’re fun, campy, not at all meant to be taken seriously, yet can be useful in teaching about biology due to their reliance upon urban legends. Still, some things about them do get on my nerves.
Let’s take an episode of the television show Fringe: Immortality (13th episode of the 3rd season). Fringe is your typical X-Files wannabe show with writing that’s sub-par even for prime-time TV. The show centers around investigators who investigate apparent criminal abuses of science. And there’s a doomsday device in a parallel universe, somehow woven into the plotline, which feels like a very uncreative and poorly done rip-off of the parallel universe in the Doctor Who episode Rise of the Cybermen.
Anyway, the Immortality episode is about entomology, in which a mad scientist genetically modified a sheep parasite which somehow has a protein which cures a deadly flu. The episode made no sense to me for reasons I’m going to get into in a few moments, but there’s something more important I’d like to get to first because I think it’s an important part of how scientists are viewed in popular culture.
Before moving to the southern US, I lived in Iowa. If there’s one thing Iowa’s known for, it’s known for our row crops. Everywhere in the summer is green and pretty and filled with all sorts of farmland and not much visible biodiversity outside of that.
If you live in certain areas of the south, it’s really actually very similar. There are lots of rowcrops… peanuts and soybeans instead of corn and soybeans but still a similar concept. Lots of crops. Everything’s green and pretty without a whole lot of biodiversity. There’s one other major difference, though…lots of areas look like this:
The green curtain draped over everything? Kudzu.
Kudzu was a vine originally planted to control erosion which grew out of control. It grows quickly, is hard to kill and covers everything with a green blanket and crowds everything out by keeping sunlight from reaching the plants. The trees under that green carpet are all dead.
So… how can things get worse?
Simple, really… just introduce something which lives on kudzu.
The wasps in the video below are most likely from the family Braconidae. These wasps make their living as parasitoids, growing within other animals and eventually eating them from the inside out. Their life starts as an egg which is laid in the caterpillar by a female. This egg may divide into many, many larvae which feed on the caterpillar from the inside by either eating the caterpillar’s fat body, it’s muscles or by drinking it’s hemolymph (which functions as blood). After they’ve completed their development, they simply exit the caterpillar by burrowing out of it and then pupate. A few weeks later, adult wasps emerge to fly away and look for other hosts.
So what makes Braconid (and Ichneumonid!) wasps so strange, and why am I writing about them on Biofortified?
My name is Joe and I’m going to be an occasional guest blogger here at Biofortified. The area I write about is going to be a bit different than most of the other writers on this website. Instead of writing about genetically modified plants, I’m going to spend a large portion of my time writing about genetically modified insects and insect pathogens.
It may seem odd to some that a blog that mostly focuses on controversies in modern agriculture would ask someone who studies insects to write on their site, but it’s not as counter intuitive as you think. Insects are a huge part of agriculture because they are our biggest competitors for food. One of the most common types of genetically modified corn, the various BT cultivars, were developed to fight the European Corn Borer, Ostrinia nubilalis, which is a tiny Crambid moth which burrows into the stalks of the plants and eventually kills them.
Biofortified's volunteer authors are devoted to providing factual information and fostering discussion about agriculture, especially plant genetics and genetic engineering. The site is written by grad students, professors, and guest experts. Meet our authors on the Authors page.
