New research delivers a sting in the tail for queen wasps. Scientists have sequenced the active parts of the genome — or transcriptome — of primitively eusocial wasps to identify the part of the genome that makes you a queen or a worker. Their work, published in BioMed Central's open access journal Genome Biology, shows that workers have a more active transcriptome than queens. This suggests that in these simple societies, workers may be the 'jack-of-all-trades' in the colony -...

Fruit Flies Force Their Young To Get Liquored-up For Their Own Good
2013-02-22 10:59:06

Emory University When fruit flies sense parasitic wasps in their environment, they lay their eggs in an alcohol-soaked environment, essentially forcing their larvae to consume booze as a drug to combat the deadly wasps. The discovery by biologists at Emory University is being published in the journal Science on Friday, February 22. “The adult flies actually anticipate an infection risk to their children, and then they medicate them by depositing them in alcohol,” says...

April Flowers for redOrbit.com - Your Universe Online How do you look for your perfect mate? Perhaps you take long walks on the beach, share a candlelight dinner, have a virtual date on Skype; or maybe it's smelling that scent of just the right perfume. When it comes to finding the perfect mate in the insect world, especially for a member of one particular wasp species, it only takes a whiff of the special love potion to know you have found "Mr. Right." Most insects rely on their...

Predator Wasps Disguise As Ants To Hunt And Capture Prey
2013-02-04 12:36:11

Pensoft Publishers Two wasp species, Calymmochilus dispar and Gelis apterus, have been recorded as parasitoids on ant-eating spiders in a study published in the open access journal ZooKeys. The host spider, Zodarion styliferum, belongs to the largest genus of predominantly ant-eating spiders. Their distribution area includes Europe, Asia and North Africa, significantly with at least 35 species reported for the Iberian Peninsula only, marking a record in numbers in Portugal, where this...

Emerald Cockroach Wasp Is Both Neurochemist And Microbiologist

Alan McStravick for redOrbit.com — Your Universe Online We all remember the dinner scene in the hit 1979 film ℠Alien´. Everything seemed fine, when all of a sudden an alien parasite emerged from the chest cavity of Ian Holm, introducing a new form of horror in the science fiction genre. But was it, in fact, science fiction? Right here on earth, in the insect world, this phenomenon appears to be nothing new. Of course, the alien in the film was foreign and ugly and...

Rearing Technique Could Help Biocontrol Wasp's Commercial Prospects
2012-10-09 17:46:56

Two to three millimeters long, the parasitoid wasp Habrobracon hebetor is a top candidate for use in programs to biologically control Indianmeal moths and other stored-product pests. But despite the prospects for reduced insecticide use and product losses, the approach has yet to gain traction commercially, in part because of the lack of an efficient method of stockpiling the wasp. But a team of scientists, including researchers from the U.S. Department of Agriculture (USDA), is working on...

Predator And Prey: Tiny Wasp Hunts Venomous Redback Spider
2012-09-12 05:48:04

Lee Rannals for redOrbit.com - Your Universe Online Even Australia's most common dangerous spider is no match for a nearly forgotten 200 year old flying insect, according to recent findings. The wasp, Agenioideus nigricornis, was first discovered in 1775 by Danish etymologist Johan Christian Fabricius. Recently, researchers from the University of Adelaide said the small wasp is a predator of the redback spider. "Since then, scientists have largely forgotten about the wasp," said...

Two parasitic wasp species show similar memory consolidation patterns in response to rewards of different quality, providing evidence that the reward value affects the type of memory that is consolidated. The full results are reported Aug. 22 in the open access journal PLOS ONE. The researchers, led by Marjolein Kruidhof of the Netherlands Institute of Ecology, tested how wasps store scents associated with situations of low reward (egg-laying into a inferior-quality host species that lays...

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...

Orchard Mason Bee, Osmia lignaria
2013-07-10 14:38:22

The orchard mason bee (Osmia lignaria), also known as the blue orchard bee, is a species of megachilid bee that is native to North America. Its range extends across the Rocky Mountains, where two subspecies are located. The nests of this species are made in natural hollows in which the bees will make separate rooms for larvae by creating walls with mud. The orchard mason bee can first be seen the early spring months, when temperatures reach about fifty-seven degrees Fahrenheit. Males leave...

Spider wasps, also called pompilid wasps or spider-hunting wasps, are insects belonging to a diverse family named Pompilidae, of the order Hymenoptera. Spider wasps are sometimes distinct from other wasps in features such as eye structure (no notch as in Family Vespidae), legs modified for grooming, and in having a groove dividing the mesopleuron (a region of the thorax) into halves. Larvae can also be identified by physical examination. Females are often larger than the males, with...
