Brett Smith for redOrbit.com - Your Universe Online Florida residents are voicing their opposition to the release of genetically modified (GM) mosquitoes by a British pest control company; despite the fact that the pesky critters were engineered to impede the spread of dengue fever. Dengue Fever, which comes from a virus spread by the bite of an infected mosquito, was first recognized in the 1950s, yet has become a leading cause of hospitalization and death among children in tropical...

Vampire Jumping Spiders Are Picky Eaters
2012-06-07 09:43:12

Do we now need to worry about vampire spiders? Well, only if you live in New Zealand and are a female mosquito. Picky eaters by any standards, E. culicivora jumping spiders, also known as vampire spiders, feed almost exclusively on female mosquitoes, which are filled with blood from their victims. Ximena Nelson from the University of Canterbury, New Zealand, says, “You can see from the diet when you find them in the field that there is a high number of mosquitoes in what they...

How Are Mosquitoes Able To Fly In The Rain?
2012-06-05 08:55:00

[ Watch the Video ] Brett Smith for redOrbit.com Anyone who has ever seen mosquitoes fly in the rain has probably rooted for the tiny pests to be taken out of the air by the constant barrage of aqua missiles sometimes weighing 50 times their mass. Unfortunately, mosquitoes have nothing to worry about because their low mass, wing design, hydrophobicity, and hard exoskeleton afford them substantial protection from the rain, according to a new report published in the Proceedings of...

Increases in the diversity of parasites that attack amphibians cause a decrease in the infection success rate of virulent parasites, including one that causes malformed limbs and premature death, says a new University of Colorado Boulder study. According to CU-Boulder Assistant Professor Pieter Johnson, scientists are concerned about how changes in biodiversity affect the risk of infectious diseases in humans and wildlife. Charting the relationships between parasites and amphibians is...

New tray and rack system is expected to be able to successfully rear 140,000—175,000 adult mosquitoes per rack The requirement for efficient mosquito mass-rearing technology has been one of the major obstacles preventing the large scale application of the Sterile Insect Technique (SIT) against mosquitoes. However, according to a new article in the next issue of the Journal of Medical Entomology, scientists at the Untited Nations Food and Agriculture Organization (FAO) and the...

Malaria infections among infants can be cut by up to 30 per cent when antimalarial drugs are given intermittently over a 12 month period, a three-year clinical trial in Papua New Guinea has shown. The trial showed the drug regime was effective against both Plasmodium falciparum and Plasmodium vivax malaria, the first time antimalarial drugs have been shown to prevent infections by both species of malaria. The treatment regime, called intermittent preventive treatment (IPT), protected the...

Carnivores in the Iberian Peninsula, such as the Iberian lynx, are under an increasingly serious threat: ticks that can adapt to changing climatic conditions and that can even survive in extremely arid environments. A study headed by Spanish researchers confirms the innate ability of ticks to adapt according to climate. The life cycle of ticks varies with changes to the climate, habitat or movement patterns of people and goods. These parasites and the pathogens they carry are a danger to...

New mathematical model explains how hosts survive parasite attacks In nature, how do host species survive parasite attacks? This has not been well understood, until now. A new mathematical model shows that when a host and its parasite each have multiple traits governing their interaction, the host has a unique evolutionary advantage that helps it survive. The results are important because they might help explain how humans as well as plants and animals evolve to withstand parasite...

Some disease-causing parasites are known to favor one sex over the other in their host species, and such differences between the sexes have generally been attributed to differences in immune responses or behavior. But in a new article, published February 28 in the magazine section of the online, open-access journal PLoS Biology, David Duneau from Cornell University and Dieter Ebert from the University of Basel now propose that all sorts of characteristics that differ between the sexes of the...

Pork Tapeworm, Taenia solium
2014-01-12 00:00:00

The pork tapeworm (Taenia solium), also known simply as a tapeworm, is a species of parasitic worm that is classified within the Platyhelminthes phylum. This species infects pigs and humans in many areas of the world including Africa, Southern Europe, Asia, South America, and some areas of North America. This species can cause cysticercosis in its larval stage, which is one of the major causes of seizures in humans. The pork tapeworm can reach an average body length between 2 to 3 meters, but...

Paragonimus westermani

Paragonimus westermani is a species of fluke, or flatworm that is classified within the Platyhelminthes phylum. This species is abundant in South America and Asia and affects the lungs of humans and other hosts. It was first discovered in 1878 in Europe after two Bengal tigers died. In 1879, Ringer found this species in the lungs of a human. Manson and Erwin von Baelz identified the sputum and eggs separately in 1880, after which Manson asserted that a snail was most likely the worm's...

Echinococcus multilocularis

Echinococcus multilocularis is a species of tapeworm that is classified within the Platyhelminthes phylum. It is one of a few worms that cause echinococcosis, a disease that affects many canid species including wolves, coyotes, foxes, jackals, domesticated dogs. Humans can also contract this disease. Adult members of this species can reach an average length of .2 inches, and like other species of tapeworm, its body is segmented by three proglottids. Its head, or scolex, is equipped with...

Trichinella spiralis

Trichinella spiralis, sometimes known as the pork worm, is a parasite within the Nematoda class. It can be found in pigs, rats, humans, and bears. This worm causes trichinosis in humans, most often from consuming undercooked pork. This species is the smallest within its class, reaching an average body length of .16 centimeters. Females are twice as large as males, displaying a sexual dimorphism. The reproductive organs of females are unique to the species in that the front end holds developed...

Guinea Worm, Dracunculus medinensis

The Guinea worm (Dracunculus medinensis) is a species of roundworm with the Nematoda phylum. This species is once ranged throughout Asia and Africa, including the west coasts of Africa in Guinea. Although it is not present in this range anymore, the species retains its common name. It was identified in this area by Carl Linnaeus, who discovered the parasite in many merchants along the coast. Its scientific name was also given due to a large population in one area, called Medina. Dracunculus...
