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...

A co-evolutionary arms race exists between social insects and their parasites. Army ants (Leptogenys distinguenda) share their nests with several parasites such as beetles, snails and spiders. They also share their food with the kleptoparasitic silverfish (Malayatelura ponerophila). New research published in BioMed Central's open access journal BMC Ecology shows that the silverfish manage to hide amongst the ants by covering themselves in the ant's chemical scent. Myrmecophilous...

Whether a species can evolve to survive climate change may depend on the biodiversity of its ecological community, according to a new mathematical model that simulates the effect of climate change on plants and pollinators. The findings, published in the early online edition of Evolutionary Applications, are important because some species that have survived large climatic change in the past might not be able to survive current and ongoing climate change. In the study, researchers used...

The research program AQUA Palawana has been exploring the unique freshwater biodiversity of the Philippine Island and biosphere reserve of Palawan for more than a decade. Scientists from the Senckenberg Museum of Zoology Dresden and the Bavarian State Collections of Zoology in Munich have now described larvae and a new species of the curious Spider Water Beetles (Ancyronyx) from this biodiversity hotspot. Their study was realized in cooperation with the Palawan Council for Sustainable...

Image 1 - Gypsy Moth Caterpillars Are Hormonal Slaves To Virus Gene
2011-09-09 07:19:47

  Gypsy moth caterpillars infected with baculovirus forfeit safety and stay in the treetops during the day because a virus gene manipulates their hormones to eat continuously and forego molting, according to entomologists. The caterpillars die where they climb and infect other gypsy moth caterpillars. "Normally, gypsy moth caterpillars are active at night," said Kelli Hoover, professor of entomology, Penn State. "They hide during the day in the soil or bark crevices protected from...

By Dennis O'Brien, ARS A U.S. Department of Agriculture (USDA) scientist is trying to learn what is causing the decline in bumble bee populations and also is searching for a species that can serve as the next generation of greenhouse pollinators. Bumble bees, like honey bees, are important pollinators of native plants and are used to pollinate greenhouse crops like peppers and tomatoes. But colonies of Bombus occidentalis used for greenhouse pollination began to suffer from disease...

The researchers discovered that a rainforest vine, pollinated by bats, has evolved dish-shaped leaves with such conspicuous echoes that nectar-feeding bats can find its flowers twice as fast by echolocation. The study is published today in Science. While it is well known that the bright colours of flowers serve to attract visually-guided pollinators such as bees and birds, little research has been done to see whether plants which rely on echolocating bats for pollination and seed dispersal...

Ant colonies with more behavioral variety are more successful / New findings in ant behavioral research They attack other colonies, plunder and rob, kill other colonies' inhabitants or keep them as slaves: Ants are usually regarded as prototypes of social beings that are prepared to sacrifice their lives for their community, but they can also display extremely aggressive behavior towards other nests. The evolution and behavior of ants, in particular the relationship between socially...

Pheromone preference, and the initiation of a complex programmed sexual behavior, is determined by the specificity of a single sex pheromone receptor protein expressed in a population of olfactory receptor neurons in the silkmoth (Bombyx mori). The study, which will be published on June 30th in the open-access journal PLoS Genetics, provides the first direct proof of the long-held belief that the control of sexual behavior in male moths originates in the chemical specificity of the pheromone...

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...
