3 European parasitoid wasp 'species' are seasonal forms of just 1 Three widely differing forms of European Scambus parasitoid wasps that had previously been regarded as distinct species are shown to be seasonal morphs of a single species. The collaboration involved National Museums Scotland (Mark Shaw), a private individual (Malcolm Jennings) and Imperial College London + Natural History Museum (Donald Quicke). It was published in the open access Journal of Hymenoptera Research. The...

Mob Tactics Help Vicious Queen Ants To Reach The Top
2011-09-30 04:21:30

Leptothorax acervorum ants live all over the Northern hemisphere, but their reproductive strategy depends on habitat. Colonies are polygynous (more than one queen) in the forest of Siberia and central Europe, but functionally monogynous (only one queen reproduces) on sun-exposed slopes in Alaska, Hokkaido and the mountains of central Spain. New research published in BioMed Central's open access journal BMC Ecology demonstrates that when a colony is functionally monogynous not only do queen...

Scientists are reporting deep new insights into whys and hows of the famous caste system that dominates honey bee societies, with a select few bee larvae destined for royalty and the masses for worker status. Their study probing the innermost biological makings of queen bees and worker bees appears in ACS's Journal of Proteome Research. Jianke Li and colleagues (The joint work of scientists from China and Ethiopia) note that despite more than a century of research, mysteries remain about...

Image 1 - Developmental Differences Controlled By Rapidly Evolving Genes
2011-09-19 10:15:28

  Genes essential to producing the developmental differences displayed by social insects evolve more rapidly than genes governing other aspects of organismal function, a new study has found. All species of life are able to develop in different ways by varying the genes they express, ultimately becoming different shapes, sizes, colors and sexes. This plasticity permits organisms to operate successfully in their environments. A new study of the genomes of social insects provides...

New UA research has discovered that seed beetles from the desert Southwest shelter their broods from attacking parasitic wasps under a stack of dummy eggs They lead modest lives among the palo verde, mesquite and acacia trees throughout the Southwestern U.S., laying their eggs on seed pods and defending the survival of their offspring against the parasitic wasp species that attacks their eggs before their young can develop. They are the seed beetles Mimosestes amicus, living all around...

Flight attacks of small parasitoid wasps (no larger than 2.0 mm in size) on ant workers have been filmed by José María Gómez Durán from Madrid. The four species of wasps show amazing adaptations and enormous differences in the tactics they use. Two of the four filmed species are new to science and are described by Dr Kees van Achterberg from NCB Naturalis Leiden. The study was published in the open access journal ZooKeys. Ants are a very...

ATLANTA, Aug. 19, 2011 /PRNewswire/ -- As Americans gear up for the final days of summer with last-minute vacations and Labor Day barbeques, one tradition remains as constant as back-to-school sales - pest activity. In a recent Omnibus survey conducted by Atlanta-based pest control leader Orkin, flies (45 percent), flying and stinging insects (40 percent) and mosquitoes (39 percent) were most frequently seen in and around homes within the past month. In addition, 30 of 31 Orkin region...

Bees use their eyes to tell them how best to streamline their bodies for rapid flight, a world first study shows. Scientists at The Vision Centre have fooled the honeybee into revealing its flying secrets by tethering the creature and running background images past its eyes. This tricks the bee into thinking it is "Ëœflying' and it moves its body into a posture for rapid flight "“ even though both it and the air are still. The research indicates that vision is an important...

By Louis Bergeron, Stanford University Stanford sophomores studying ants in a summer course discovered that the local ants were using poison to kill invading Argentine ants. The discovery provides new insight into the war between the local "winter ants" and the South American invaders who have shown up everywhere from California to South Africa. Argentine ants are taking over the world "“ or at least the nice temperate parts. They've spread into Mediterranean and subtropical climates...

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...
