University of Montreal New study on parasitoid reveals that heat favours production of male progeny Whether an insect will have a male or female offspring depends on the weather, according to a study led by Joffrey Moiroux and Jacques Brodeur of the University of Montreal's Department of Biological Sciences. The research involved experimenting with a species of oophagous parasitoid (Trichogramma euproctidis), an insect that lays its eggs inside a host insect that will be consumed by the...

Pensoft Publishers An inventory of wild-caught caterpillars, its food plants and parasitoids, has been going on for more than 34 years in Area de Conservación Guanacaste (ACG), a protected area of approximately 1200 km2 in northwestern Costa Rica. As a result, more than 10,000 species of moths and butterflies are estimated to live in ACG. Their caterpillars are in turn attacked by many parasitoid wasps, also numbering thousands of species. However, most of those wasps have never been...

Wasps Used To Fight Citrus Greening Disease Are Unlikely To Threaten Non-target Insects
2014-02-04 08:35:10

Entomological Society of America In August 2008 the Asian citrus psyllid (Diaphorina citri), an invasive insect known to spread citrus greening disease (huanglongbing), which can be lethal to citrus trees, was detected in southern California. After initial treatments with insecticides were determined to be costly and unsustainable, a decision was made to instead try biological control by using insect parasitoids that are known to attack the psyllids. However, since the only known...

Fruit Flies Pickier Than You Think
2013-12-05 19:17:53

Cell Press On your kitchen counter, it might seem as though fruit flies will show up for just about any type of fruit you leave around for them. But when given a choice about where to lay their eggs, those flies will go for citrus most of the time, new work shows. The basis for that seemingly complex food preference is surprisingly simple, according to a report in the Cell Press journal Current Biology on December 5. It boils down to a single odorant receptor found on a single class of...

Remarkable 277 New Wasp Species Discovered In Costa Rica
2013-11-06 11:56:18

Pensoft Publishers Costa Rica reveals astonishing biodiversity of braconid wasps, with 277 new species of the tribe Heterospilini described in the latest special issue of the open access journal ZooKeys. This is the second part of an extensive two-part study of the braconid subfamily Doryctinae from Costa Rica, the first part published In this part, the authors Paul M. Marsh, and Alexander L. Wild and James B. Whitfield, University of Illinois at Urbana-Champaign, describe a total of...

Beetles In Central And South America Show Signs Of Maternal Instincts

Pensoft Publishers Hidden in the thick foliage of tropical forests a subfamily of colorful beetles hides the secrets of the earliest stages of social behavior, showing explicit signs of maternal instincts and care. An international team of scientists from the Smithsonian Tropical Research Institute, Centro Universitário de Lavras, Staatliches Museum für Naturkunde Karlsruhe, and Université libre de Bruxelles looked into the complex subsocial behaviors present in the extraordinary...

New Study Presents New Wasp Species From The Distinctive Odontacolus And Cyphacolus Genera
2013-07-04 10:51:42

Pensoft Publishers The wasp family Platygastridae is a large group of tiny, exclusively parasitoid wasps distributed worldwide. The genera Odontacolus and Cyphacolus, belonging to this family, are among the most distinctive wasps because of the peculiar hump-like formation on the rear part of their bodies. Despite their intriguing body shape, the generic status of these two groups has remained unclear. A new extensive study published in the open access Zookeys presents a morphological...

Parasitic Wasp Populations Are Increasing And Expanding In Michigan
2013-06-05 15:49:51

Entomological Society of America The emerald ash borer (EAB), a relatively new invasive insect pest, has killed tens of millions of ash trees throughout the eastern United States since it was first detected in 2002 in Michigan and Canada. This insect has the potential to kill an estimated seven billion ash trees in urban and rural forests and could cause tens of billions of dollars in damage. To control the EAB, research on its natural enemies was initiated shortly after its discovery,...

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...

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...

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....
