European Paper Wasp Never Cries Wolf
2012-08-20 07:13:34

European paper wasps (Polistes dominula) advertise the size of their poison glands to potential predators, finds a new study published in BioMed Central's open access journal Frontiers in Zoology. The brighter the color, the larger the poison gland. Aposematism is used by many different animals to warn potential predators that they are poisonous. Usually this takes the form of distinctive coloration or patterns which predators quickly learn to avoid. Paper wasps have conspicuous yellow and...

Farm Productivity Supported From Wild Pollinators
2012-08-17 09:45:10

Most people are not aware of the fact that 84% of the European crops are partially or entirely dependent on insect pollination. While managed honeybees pollinate certain crops, wild bees, flies and wasps cover a very broad spectrum of plants, and thus are considered the most important pollinators in Europe. The serious decline in the number of managed honeybees and wild bees reported in Europe over the last few decades has the potential to cause yield decreases with threats to the...

Asymmetric Warfare Between Earwigs Probed By Researchers
2012-08-16 07:07:24

Symmetrical looks are highly prized in the animal kingdom, but according to a new report by San Francisco State University biologists on an insect called the maritime earwig, asymmetry might come with its own perks. Animals–including humans–seem to use symmetry as a shortcut for evaluating potential mates. Symmetrical features usually indicate normal development, while asymmetry could point to an underlying developmental defect that would render a mate less fit. "The...

Predatory beetles can detect the unique alarm signal released by ants that are under attack by parasitic flies, and the beetles use those overheard conversations to guide their search for safe egg-laying sites on coffee bushes. Azteca instabilis ants patrol coffee bushes and emit chemical alarm signals when they're under attack by phorid flies. In an article published online July 27 in the journal Ecology and Evolution, University of Michigan researchers and their colleagues show that...

Insects learn faster when they are rewarded with nectar Butterflies learn faster when a flower is rewarding than when it is not, and females have the edge over males when it comes to speed of learning with rewards. These are the findings of a new study, by Dr. Ikuo Kandori and Takafumi Yamaki from Kinki University in Japan. Their work, published online in Springer's journal Naturwissenschaften - The Science of Nature, is the first to investigate and compare the speed at which insects learn...

Insects Aren't Bugged By Summer Heat
2012-07-25 14:40:11

redOrbit Staff & Wire Reports - Your Universe Online The summertime heat may bug humans, but America´s insect population can´t get enough of it. According to the National Pest Management Association (NPMA), this year´s record high temperatures have brought the bugs out from the woodwork as pests such as ants, fleas, ticks and black widow and brown recluse spiders are increasing. The heat is causing a greater number of insects to come out early in the day to eat and...

Caterpillar Gets The Most From Food When Predator Is On The Hunt
2012-07-13 13:37:15

redOrbit Staff & Wire Reports - Your Universe Online While other animals beef up metabolism and stop growing or developing during a defensive period, hornworm caterpillars slow or stop eating but actually keep up their weight and develop a little faster in the short term. Hornworm caterpillars ate 30 percent to 40 percent less when threatened by stink bugs but weighed the same as their non-threatened counterparts as indicated by Ian Kaplan, a Purdue University assistant professor of...

Pests Are Adapting To GM Crops In Unexpected Ways
2012-06-21 05:12:02

Brett Smith for redOrbit.com Modern science is no match for Mother Nature when it comes to agriculture, a new research paper has revealed. The report, published in the Proceedings of the National Academy of Sciences by a team of scientists, showed that pests are adapting faster than expected to the genetically modified (GM) crops that have been altered to repel them. Many GM crops were originally created to reduce the amount of pesticides used to repel the insects and larvae that...

The water boatman's unique propulsion system was studied by researchers from China Superhydrophobicity is one of most important interfacial properties between solids and liquids. SHI Yanlong and his group from the College of Chemistry and Chemical Engineering, Key laboratory of Hexi Corridor Resources Utilization of Gansu Universities, Hexi University investigated the superhydrophobicity of the water boatman's hind wings. The study showed that superhydrophobicity plays a crucial role in...

Insects can use plants as ℠green phones´ for communication with other bugs. A new study now shows that through those same plants insects are also able to leave ℠voicemail´ messages in the soil. Herbivorous insects store their voicemails via their effects on soil fungi. Researchers from the Netherlands Institute of Ecology (NIOO-KNAW) and Wageningen University (WUR) discovered this unique messaging service in the ragwort plant. The influential journal Ecology Letters will...
