It is so new, and so bizarre, that uber-naturalist E. O. Wilson has christened it "the ant from Mars." Martialis heureka, a native of the Brazilian Amazon, is the founding member of a new subfamily of ants. It adds a new branch to the ant family tree which split off from the others extremely early in the family's evolution. "It could represent a 'relict' species that retained some ancestral morphological characteristics," says discoverer Christian Rabeling, a graduate student in integrative biology at the University of Texas in Austin 
DEET's Not Sweet to Mosquitoes, Groundbreaking Research Shows

Spray yourself with a DEET-based insect repellent and the mosquitoes will leave you alone. But why? They flee because of their intense dislike for the smell of the chemical repellent and not because DEET jams their sense of smell, report researchers at the University of California, Davis.
Fancy Footwork Helps Flies Cheat Death

A study discovered that the fly anticipates the direction of a looming threat and makes split-second movements that better prepare it to take off in the opposite direction. The findings reveal a level of movement planning rarely seen in such a simple organism.

This experiment was undertaken to assess the advantages of using diallel crosses to define combining ability and understand heterosis in a broad-based wheat-breeding population across different environments affected by yellow rust. This research shows the power of available quantitative breeding tools to help breeders choose parental sources in a population improvement programme.
Searching for a better mosquito repellent

Most people in hot places--or even just hot weather--are troubled by mosquitos. What is an annoyance in some parts of the world, however, can be fatal in others. In this stuty, the scientists point out that it is necessary to search for more effective repellents, one of which is introduced in this article, lasting a record 85 days!
Eusocial insects could have started with monogamous pairs
Darkfrog submitted, created time 4 months 6 days (sciencenow.sciencemag.org)
After reading all those depressing articles about how even monogamous species like swans and wolves cheat on their partners, this one was a bit refreshing. The authors posit that monogamy might be the foundation of cooperative species, at least in the beginning. These findings support the idea that cooperative insects group together because of the chance to let a sister pass on her genes and less because of straight survival.
Global warming threatens tropical insects

From this study, we know that insects in the tropics are much more sensitive to temperature changes than those elsewhere. U.S. scientists have said that many tropical insects face extinction by the end of this century unless they adapt to the rising global temperatures predicted.
Collective Motion and Cannibalism in Locust Migratory Bands

We know that plagues of mass migrating insects such as locusts are estimated to affect the livelihood of one in ten people on the planet. Because of above reason, identification of generalities in the mechanisms underlying these mass movements will enhance our understanding of animal migration and collective behavior while potentially contributing to pest-management efforts.
Study proves that intelligence can be a detriment to survival in some species
Darkfrog submitted, created time 5 months 21 hours (www.nytimes.com)
Okay, it's been fairly obvious for some time that humans' large and shapely brains involve some kind of evolutionary tradeoff. What is it, a third or a fourth of our blood flow that goes directly to the brain? I don't know. Well, this study shows that intelligence does not always increase an organism's odds for survival. Fruit flies bred to learn faster and surer were consistently larva-slapped by their troglodytic brethren.
Food crisis calls for renewed vigor in agricultural research
Darkfrog submitted, created time 5 months 5 days (www.nature.com)
Agricultural research may not sound flashy--it includes everything from high-yield crop varieties to pest and weed control--but experts claim that a lack of it is the underlying cause of our current food shortages in the developing world, and that it is likely to be the cause of future shortages if the problem is not corrected.
While there is a focus on agricultural research in the developing world, this is limited to four countries: China, Brazil, South Africa and India. At the same time, there is less and less transfer of technology and information from first-world countries like the U
Two Resistance Genes for the Price of One--Ideal?
Sue Wu submitted, created time 5 months 3 weeks (sciencenow.sciencemag.org)
It seems like a no-brainer, even for mosquitoes: Why be resistant to one pesticide when you can be resistant to two? In practice, however, such adaptations weaken insects in other ways, so more might not be a good thing.
Scientists Complete Sequencing Red Flour Beetle Genome

Scientists have completed sequencing the entire genetic blueprint of a key agricultural pest: the red flour beetle.
This accomplishment is a "first" for any beetle.

Researchers have developed a computer algorithm that can identify some plant species according to their unique sonar echoes. The experiments were meant to help biologists understand how bats find their favorite fruits or insects, but the research might also help engineers design high-speed systems to identify everything from widgets on conveyor belts to faces in crowds.
How to Keep a Wasp from Cheating
Vincent submitted, created time 6 months 3 weeks (sciencenow.sciencemag.org)
It would be easy for fig wasps to cheat. These tiny insects pollinate figs in exchange for a share of the tree's seeds--and theoretically, the wasps could lay claim to more seeds than they deserve. But they don't, and now biologists know why. Parasitic wasps, usually thought of as the bad guys, keep the pollinators honest.
Local birds starve as foreign shrubs escape!
Darkfrog submitted, created time 7 months 17 hours (www.nytimes.com)
People worry their heads off about genetically engineered crop plants, but these are often the same people who plant off-continent shrubs in their gardens. They escape. The bugs can't eat 'em. The birds go hungry. The end.
This quote in particular struck me:
"Although gardeners might believe that when they plant a butterfly bush, native to China, they are helping butterflies, they are merely attracting the adults who sip the nectar. The plant cannot be eaten by the butterfly larvae."
Now, ordinarily, I don't care to feed larvae. I want them to die because they're horrid
