Solomon's lily imitates a yeasty odor to lure vinegar flies into a trap Scientists from the Max Planck Institute for Chemical Ecology in Jena, Germany, have solved a case of fraud that has been pending for 40 million years. Arum palaestinum, also called the Solomon's lily, attracts drosophilids (vinegar flies) as pollinators by emitting odor molecules that resemble those produced during alcoholic fermentation of rotting fruit initiated by yeast. The plant accomplishes the illusion of yeast...

Nectar production in lima beans depends on light quality Flowering plants produce nectar to attract insect pollinators. Some plant species, such as Lima bean, also secrete nectar from so-called extrafloral nectaries to attract ants which in turn fend off herbivores. Scientists of the Max Planck Institute in Jena, Germany, have discovered that the production of extrafloral nectar is light dependent. They have shown that the plants are able not only to distinguish between day and night, but...

Bee I.D. study will help scientists research biodiversity A York University doctoral student who discovered a new species of bee on his way to the lab one morning has completed a study that examines 84 species of sweat bees in Canada. Nineteen of these species "“ including the one Jason Gibbs found in downtown Toronto ∴ are new to science because they have never been identified or described before. Gibbs' expansive study will help scientists track bee...

Why do some insect-eating plants like sundews keep their flowers so far away from their traps? New research suggests that it isn't a clever trick to keep pollinators safe, it's about getting pollinated Sex can be complicated at the best of times, but plants have an extra difficulty. If you're a plant who relies on insects to pollinate your flowers and reproduce, you will want your flowerstalks to be long. That way your flowers are on display to insects above the crowd. But if your stalk is...

In the battle between insect predators and their prey, chemical signals called kairomones serve as an early-warning system. Pervasively emitted by the predators, the compounds are detected by their prey, and can even trigger adaptations, such a change in body size or armor, that help protect the prey. But as widespread as kairomones are in the insect world, their chemical identity has remained largely unknown. New research by Rockefeller University's Joel E. Cohen and colleagues at the...

The defining feature of social insects is that societies contain queens, which specialise in laying eggs, as well as workers, which are mostly infertile but take care of the offspring and the nest. However, when the queen dies or is re-moved, workers begin laying eggs of their own. Previous observations have suggested that queens possess a specific pheromone which keeps the workers infer-tile, but the pheromone has never been identified except in the well-studied honeybee. Queen pheromones...

Sex pheromone production in European corn borer races explored -- tracking the origin of new species The coming of summer brings promise for humans and insects alike. The farmer planted maize for a bountiful harvest, but the European Corn Borer (ECB) is looking for a good meal right away. The caterpillars of this pest bore deep into the maize stems, where they eat the inner pith causing the weakened stalks to fall over before the ears can ripen. As if one pest were not bad enough, there are...

On Wednesday, a conservation group filed a petition to add a bumblebee from Southern Oregon and Northern California to the endangered species list. The Xerces Society for Invertebrate Conservation and University of California at Davis entomologist Robbin Thorp formally petitioned the U.S. Fish and Wildlife Service to protect the inset under the Endangered Species Act. Executive director of the Xerces Society in Portland, Scott Hoffman Black, told the Associated Press (AP) the petition is...

DAVIS, Calif., May 7 /PRNewswire-USNewswire/ -- If USDA and the Xerces Society have their way, long rows of native wildflowers, clovers and blooming shrubs could border agricultural fields all across California. Currently the concept is in full bloom at USDA's Plant Materials Center (PMC) near Lockeford, Calif., where the partners hope to demonstrate to farmers and the public both the beauty and the practical benefits of planting forbs such as California poppies, lupines, baby blue eyes,...

Researchers in the Department of Entomology,  University of California, Davis, have discovered that the fruit fly has a native odorant receptor that detects the silkworm moth's sex pheromone, and that it's "amazingly more sensitive" than the moth's odorant receptor. Their work could open research doors for insect-inspired biosensors. The odor detector or OR is a means of chemical communication that helps insects find mates.  The olfactory link between silkworm moths (Bombyx mori)...

Melissophobia
2013-12-24 11:13:46

Melissophobia or the fear of bees, from Greek melissa, meaning honey bee and phobos, meaning fear, and sometimes misspelled as melissaphobia and known also as apiphobia, is one of the most common fears among people and is kind of a specific phobia. The majority of the population have been stung by a bee or had friends or family members stung. A child may fall victim to a bee sting while playing outside. The sting can be rather painful and in some individuals results in swelling which might...

The baculoviruses, are a family of large rod-shaped viruses, divided into two genera: nucleopolyhedroviruses (NPV) and granuloviruses (GV). Baculoviruses have species-specific tropisms among the invertebrates with over 600 host species having been described. Moth larval is the most common hosts but sawflies, mosquitoes, and shrimp are also known hosts. The viruses are not known to replicate in mammalian or other vertebrate animal cells. In the early sixteenth century the first records of...

The ants, one of the most successful groups of insects, are of particular interest because they form advanced colonies, and can constitute up to 15 percent of the total animal biomass of a tropical rainforest. They belong to the order Hymenoptera and are close relatives of the vespoid wasps. Ants appear in amber, found in central New Jersey, believed to be from the Cretaceous period. It is thought that they evolved from the wasps that had appeared during the Jurassic period. They are...
