(The New York Times)   Fruit flies do better eating organic fruit. Subby thinks it might have something to do with the pesticides on the conventional fruit, but what does he know?   (well.blogs.nytimes.com) divider line 13

Subby knows enough.

All I know is that organic celery has superpowers. That stuff stays good for weeks in the crisper. It just won't die.

Pro tip: Don't leave empty beer or soda cans out too long.  Fruit flies have massive orgies in there.

Kurmudgeon: "Time flies like an arrow, Fruit flies like a banana"


Apparently fruit flies especially like an organic banana.

Subby addresses something I was confused about too, but haven't seen an explanation for in media coverage of this study.

I read that organic fruit is believed to be both more pest-resistant, and also more nutritious to organisms such as fruit flies that consume it.

How does the fruit know who's trying to eat it?

Sure, keep on buying that "organic" produce. Then get all pissy when boll weevils wipe out the next crop.

The same way cancer was supposed to know vitamins were supposed to cure people and not use them to grow faster instead.

You do realize that fruit flies don't eat fruit, right? Right?

I was under the impression that organic fruits are also treated with pesticides, but in smaller, more frequent doses.

It's nice that a 16-year-old high school student shows a real interest in science, but her study hardly seems definitive. Certainly several points need to be adressed before its results can be considered meaningful.
For example:
-How large was the sample size.
-Did she wash the fruit before offering it to the fruit flies (if she didn't, then any difference may not be due to the fruit itself, but to whatever coated it).
-Were the organic and inorganic fruits in her sample produced on the same farm ? if not, her results may reflect differences between two different farms, different transport times, different storage conditions, etc...
-Were the fruits all picked at the same time or did one sample lose more nutrients than the other due to having been on the store shelf longer.

etc...

shouldn't organic cost less cause they don't have to spend on pesticides?

they still use pesticides, just not synthetic ones, that last longer, and only need 2 applications per year. So they have to use more of it, and because the non-synthetics have been around since the 1950's most pests have a tolerance, and the yield is lower due to loss.

article from scientific american
Canadian scientists pitted 'reduced-risk' organic and synthetic pesticides against each other in controlling a problematic pest, the soybean aphid. They found that not only were the synthetic pesticides more effective means of control, the organic pesticides weremore ecologically damaging, including causing higher mortality in other, non-target species like the aphid's predators.
