Rare Sawfly Is Host To Peculiar Parasitoid Wasp
2013-03-25 11:28:01

Pensoft Publishers A mysterious parasitoid wasp was found in the Böhmerwald (Northeast Austria) and reared in the garden of the amateur entomologist Ewald Altenhofer of Gross Gerungs municipality, Austria. The parasitoid was identified by Kees van Achterberg, senior researcher at the Naturalis Biodiversity Center in Leiden, the Netherlands, as the rare Seleucus cuneiformis. It is the first time that a tip of its biology was discovered. The study was published in the open...

Aphid researchers from Chinese Academy of Sciences found one new species, Aleurodaphis sinojackiae Qiao & Jiang, 2011 from Jiangsu and Zhejiang Provinces, China. It forms leaf galls on Jack trees (Sinojackia xylocarpa) and is one of two known gall makers in the plant lice Aleurodaphis (Hemiptera, Aphididae, Hormaphidinae). The study was published in the open access journal ZooKeys. Aleurodaphis was established in 1917 by van der Goot and has eight known species in the world, restricted...

Important implications for global pest-control The diamondback moth, Plutella xylostella, is one of the world's most destructive crop pests. It has developed resistance to many chemical and biological pesticides, and the estimated global cost of controlling this insect is approximately US$1billion annually. In a new article published in the open access journal BMC Genomics, researchers from Australia have identified the genes expressed when the diamondback moth is attacked by a...

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...

A black, two-millimeter-long wasp from East Africa is helping wage war on one of its own kind"”the Erythrina gall wasp, an invasive species that's decimated Hawaii's endemic wiliwili (Erythrina sandwicensis) and introduced coral bean trees (Erythrina spp.). Hawaii Department of Agriculture (HDOA) officials "recruited" the beneficial wasp, Eurytoma erythrinae, and first released it in November 2008 after evaluating its host specificity as a biocontrol agent. U.S. Department of...

What can you learn from the 120 year-old body of a parasitoid wasp? Using material from museum collections, researchers writing in the open access journal BMC Evolutionary Biology report that they can tell how males wasps court their females, based on dead specimens. Parasitoid wasps are one of the most abundant groups of organisms on the planet. Their diversity makes it very hard to study behaviors across many species. Seraina Klopfstein from the Natural History Museum of Bern, Switzerland,...

Parasitic wasps kill pest insects, but their existence is largely unknown to the public. Now, scientists led by John H. Werren, professor of biology at the University of Rochester, and Stephen Richards at the Genome Sequencing Center at the Baylor College of Medicine have sequenced the genomes of three parasitoid wasp species, revealing many features that could be useful to pest control and medicine, and to enhance our understanding of genetics and evolution. The study appears in the Jan. 15...

By DANA WILDE "What's this?" my wife said. She held up a shiny, speckled red ball about the size of an acorn. Me being the amateur naturalist and science fictionist in the house, and everybody else being merely curious, she expected I'd have an answer, or at least a weird guess. "I have no idea," I said. "Where did you get it?" "Jack found it in the grass by the Shed." She handed it to me. It was smooth and looked like some kind of fruit or nut, although it had no apparent stem end. I...

A tiny wasp that lays its eggs under the skin of unwitting caterpillars belongs to one of the most diverse groups of insects on Earth. Now researchers report that its diversity is even higher than previously thought. By combining ecological and genetic data with the painstaking detective work of taxonomy, the researchers have dramatically increased "“ nearly doubling "“ the estimated number of species reported of six very species-rich genera of parasitoid wasps. The subfamily to...

HONOLULU (AP) - State officials are hoping to save Hawaii's native wiliwili tree with a bug found in eastern Africa. Mohsen Ramadan, a state exploratory entomologist, spent two months in Tanzania looking for a natural solution to fight the wiliwili-destroying Erythrina gall wasp and found a wasp of the Eurytoma species. The Eurytoma wasps feeds externally on gall wasp larvae and pupae. It attacks 95 percent of gall wasps in Tanzania. The gall wasp found its way to all of the main Hawaiian...

The Polydnaviruses (PDV) are a family of insect viruses that contain two genera: Ichnoviruses (IV) and Bracoviruses (BV). The ichnoviruses occur in ichneumonid wasps and bracoviruses in braconid wasps. The virus is composed of multiple segments of double-stranded superhelical DNA packaged in capsid proteins and a double layer or single layer envelope. The full genome of the virus is integrated into the genome of the wasps and the virus only replicates in specific cells in the female...

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...

Apocrita is a suborder of insects in the order Hymenoptera. The Apocrita include wasps, bees and ants, and are comprised of many families. They include the most advanced Hymenoptera and are distinguished from the Symphyta by the narrow waist joining two segments of the abdomen. The ovipositor of the female either extends freely or is retracted, and is converted into a sting for both for defense and for paralyzing prey. Larvae are legless, and may feed either inside a host or in a nest....
