New Wasp Species Found In 1930s Field Box
2013-03-19 04:49:57

April Flowers for redOrbit.com - Your Universe Online A new study from Dr. Simon van Noort, from Natural History Department, Iziko South African Museum, and Dr. Matthew L. Buffington from the Systematic Entomology Lab, USDA describes nine new species of extremely rare Mayrellinid wasps. Mayrellinids are under-represented in museum collections with most species being known from only a single specimen. There are two genera in the Mayrellinae subfamily, Kiefferiella and Paramblynotus. Only...

Social Bees Use Chemical Signals To Mark Dangerous Flowers
2013-03-14 13:32:43

FECYT - Spanish Foundation for Science and Technology Scientists already knew that some social bee species warn their conspecifics when detecting the presence of a predator near their hive, which in turn causes an attack response to the possible predator. Researchers at the University of Tours (France) in collaboration with the Experimental Station of Arid Zones of Almeria (Spain) have now demonstrated that they also use chemical signals to mark those flowers where they have previously...

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...

Finding Mr. Right: Understanding The Evolution Of Sex Pheromones In Wasps
2013-02-14 08:33:16

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...

Reproductive Workings Of A Harvester Ant Dynasty Uncovered By Stanford Scientist
2013-02-12 21:08:18

Stanford University For the first time, scientists have measured how successfully a queen ant establishes new colonies. The work by Stanford researchers revealed that the queen was still reproducing several decades after mating. Ants are just about everywhere you look, and yet it's largely unknown how they manage to be so ubiquitous. Scientists have understood the carnal mechanism of ant reproduction, but until now have known little of how successful the daughters of a colony are when...

Asian Needle Ants Displacing Other Aggressive Invaders
2013-02-11 10:07:43

North Carolina State University Researchers from North Carolina State University have found that one of the most aggressive invasive ant species in the United States — the Argentine ant — appears to have met its match in the Asian needle ant. Specifically, the researchers have found that the Asian needle ant is successfully displacing Argentine ants in an urban environment, indicating that the Asian needle ant — with its venomous sting — may be the next invasive...

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...

Social Chromosomes Determine How Many Queen Ants Are In Fire Ant Colony
2013-01-17 13:19:53

Lee Rannals for redOrbit.com — Your Universe Online Researchers wrote in the journal Nature that they discovered a social chromosome in fire ants that explain why some colonies allow for more than one queen ant. Red fire ants live in two different types of colonies, including some that strictly have a single queen, and others that contain hundreds of queens. Scientists discovered that this difference in social organization is determined by a chromosome that carries one of two...

For those who think they do not need exterminator services in the cold winter months, professional pest control provider explains why perceptions may be off. Windham, ME (PRWEB) December 26, 2012 People tend to rely on a belief that they need to deal with bugs during the warmer and wetter spring and summer months, but that bugs are not an issue during the cold winter months–they simply go away. Unfortunately, Ants ETC–a specialist in pest control in Windham, ME–points out...

Jack Jumper Ant, Myrmecia pilosula
2013-07-10 13:00:54

The jack jumper ant (Myrmecia pilosula), known by other names including the jumping jack or hopper ant, is a species of bull ant that can be found in Australia. Its range includes Tasmania, New South Wales, and rural areas of Victoria. This species is unique in that its genome only holds on set of chromosomes, which is the lowest number of chromosomes that any animal can hold. Like other bull ants, this species can build nests under rocks or under dirt mounds. The jack jumper reaches an...

Inchman, Myrmecia forficate
2013-07-10 12:28:46

The inchman (Myrmecia forficate) is a species of bull ant that can be found in Australia, in a range that includes Tasmania and possibly southeastern areas of Australia. This species is gregarious, living in colonies like most other ant species, but it forages for food alone. Nests often go unseen and are typically found under rocks.  It reaches an average body length of up to one inch long, the trait from which it received its common name. The inchman is both a scavenger and a...

A wasp is any insect of the order Hymenoptera and suborder Apocrita that is not a bee, sawfly, or an ant. The less familiar suborder Symphyta includes the sawflies and wood wasps, which differ from the Apocrita by having a broad connection between the thorax and abdomen. Also, Symphyta larvae are mostly herbivorous and "caterpillarlike", whereas those of Apocrita are largely predatory or parasitic. Most familiar wasps belong to the Aculeata, a division of the Apocrita whose ovipositors are...

The Bombyliids are a large family of flies with hundreds of genera. Their life cycles are not well known. Adults generally feed on nectar and pollen, thus are pollinators of flowers. They superficially resemble bees, thus are commonly called bee flies, and this may offer the adults some protection from predators. The larval stage are predators or parasitoids of other insect eggs and larvae. The adult females usually deposit eggs in the vicinity of possible hosts, quite often in the burrows...

The bumblebee is a flying insect of the genus Bombus in the family Apidae and a relative of the common honeybee. The bumblebee feeds on nectar and gathers pollen to feed its young. They are beneficial to humans and the plant world alike, and tend to be larger than other members of the bee family. Most bumblebee species are gentle. From this comes their original name: "Humblebee". Bumblebees are social insects that are known for their black and yellow striped bodies, a commonality among the...
