A pair of new studies reveals the multiple ways that a widely used insecticide harms bumblebees and honeybees. The reports, one by a U.K. team and one by a French team, appear online at the Science Express Web site of the journal Science, on 29 March, 2012. Science is published by AAAS, the nonprofit, international science society. Bumblebees and honeybees are important pollinators of flowering plants, including many major fruit and vegetable crops. Each year, for example, honeybee...

Another first, research also finds probiotic species used by humans flourishing in colonies A novel study of honey bee genetic diversity co-authored by an Indiana University biologist has for the first time found that greater diversity in worker bees leads to colonies with fewer pathogens and more abundant helpful bacteria like probiotic species. Led by IU Bloomington assistant professor Irene L.G. Newton and Wellesley College assistant professor Heather Mattila, and co-authors from...

Ants Remember Their Rivals' Scent
2012-02-22 05:49:02

Researchers from the University of Melbourne report they have found that ant colonies share a collective memory for the odor of ants in rival nests. According to the new research, the ants use the information to identify the rival ants and compete, similar to how sports fans know each other by wearing their teams' colors. Study leader Professor Mark Elgar from the University's Department of Zoology said the ant colony's collective memory helps give an edge in a competitive world by...

Organic farms produce strawberries with fewer malformations and a higher proportion of fully pollinated berries relative to conventional forms, according to a Feb. 15 report in the open access journal PLoS ONE. The study, led by Georg Andersson of Lund University in Sweden, investigated the effect of organic farming compared to conventional. They found that the pollination success increased greatly with organic farming, and speculate that this effect may be due to an increase in insect...

Bumblebees Learn To Take Cues From Honeybees
2012-02-15 04:29:01

Bumblebees can use cues from their rivals the honeybees to learn where the best food resources are, according to new research from Queen Mary, University of London. Writing in the journal PLoS ONE, the team from Queen Mary's School of Biological and Chemical Sciences explain how they trained a colony of bumblebees (Bombus terrestris) to use cues provided by a different species, the honeybee (Apis mellifera), as well as cues provided by fellow bumblebees to locate food resources on...

Male flies find romance with female flies coated with pheromone, regardless of age; U-M, international research sheds light on aging process Beauty is more than skin deep, at least for fruit flies studied in new research that demonstrates how age-related changes in pheromone production can reduce sexual attractiveness. The study, published Feb. 9 in The Journal of Experimental Biology, examined how pheromones play a role in the sexual attractiveness and aging process of the common fruit...

Aging takes its toll on sex appeal and now an international team of researchers led by Baylor College of Medicine and the University of Michigan find that in fruit flies, at least, it even diminishes the come-hither effect of the chemicals of love — pheromones. "This is new because we have direct evidence that the pheromones produced at these different ages affect sexual attractiveness differently," said Tsung-Han Kuo, a graduate student in the department of molecular and human...

Commercial beekeepers and environmentalists shed light on honey bee losses and impact on future food prices LAS VEGAS, Jan. 10, 2012 /PRNewswire-USNewswire/ -- Today, beekeepers from across the country gathered at a national conference, with environmental organizations at their side, to draw attention to the growing plight facing their industry -the decline of honey bees - a problem that has far reaching implications for the U.S. economy. "Bees and other pollinators are the...

A North Carolina State University discovery of the unique chemical composition of a cockroach signal — a "Let's hook up" sex pheromone emitted by certain female wood cockroaches to entice potential mates — could have far-ranging benefits, including improved conservation of an endangered woodpecker. Dr. Coby Schal, Blanton J. Whitmire Professor of Entomology at NC State and the corresponding author of a paper describing the discovery, says that the study, published the week of...

Bee Behavior Mimics Brain Neuron Function
2011-12-09 07:40:14

A new study of bees has come to the conclusion that bee swarm communication works similarly to that of neurons in the human brain. The study, published in the December 9 issue of Science, found that bees use inhibitory “stop” signals to prohibit the scout bees from completing a waggle dance that helps bees learn the directions of competing sites for new hives. This behavior helps to ensure that the best homesite is found for the hive. Thomas Seeley, a biologist from Cornell...

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...
