ATLANTA, June 14 /PRNewswire/ -- For many families, summer means pool parties and backyard barbeques. But where there is fun for kids, there are safety concerns for parents - like how to prevent sunburn, poolside accidents or insect bites and stings. According to Atlanta-based pest control leader Orkin, while most summer bugs like June beetles are just nuisances, summer bees, wasps and mosquitoes - and their stings or bites - can cause serious health issues. In fact, while most insect...

Social status in paper wasps is established earlier in life than scientists thought, says a study published this month in the journal PLoS ONE. While many social insects have distinct social classes that differ in appearance and are fixed from birth, paper wasp society is more fluid "” all castes look alike, and any female can climb the social ladder and become a queen. Now, molecular analysis reveals that paper wasp social hierarchy is less flexible than it appears. Queens diverge from...

Scientists from the US, Turkey, Switzerland and Iran describe the nest of an uncommon solitary bee In a rare coincidence, researchers working in both Turkey and Iran discovered on the same day how a rare species of bee builds its underground nests. The females from the solitary species Osima (Ozbekosima) avoseta line the nest's brood chambers with petals of pink, yellow, blue, and purple flowers. The chambers provide nutrients for the larvae to grow and mature and protect the next generation...

They are both nest-building social insects, but paper wasps and honey bees organize their colonies in very different ways. In a new study, researchers report that despite their differences, these insects rely on the same network of genes to guide their social behavior. The study appears in the Proceedings of the Royal Society B: Biological Sciences. Honey bees and paper wasps are separated by more than 100 million years of evolution, and there are striking differences in how they divvy up the...

Lions, tigers and bears top the ecological pyramid"”the diagram of the food chain that every school child knows. They eat smaller animals, feeding on energy that flows up from the base where plants convert sunlight into carbohydrates. A new study examines complex interactions in the middle of the pyramid, where birds, bats and lizards consume insects. These predators eat enough insects to indirectly benefit plants and increase their growth, Smithsonian scientists report. "Our findings...

One of the most common house ant species might have been built for living in some of the smallest spaces in a forest, but the ants have found ways to take advantage of the comforts of city living. Grzegorz Buczkowski, a Purdue University research assistant professor of entomology, found that odorous house ant colonies become larger and more complex as they move from forest to city and act somewhat like an invasive species. The ants live about 50 to a colony with one queen in forest settings...

Desert ants perceive odor maps in stereo and use this information for navigation Scientists of the Max Planck Institute for Chemical Ecology in Jena have investigated another navigational skill of desert ants. These ants are already well-known for their remarkable visual orientation: they use a sun compass along with a step counter and visible landmarks to locate their nest after foraging for food. After the research team from Jena recently discovered that these ants also use olfactory cues...

Broadly speaking, ants have two different feeding strategies. A large proportion of all species are "carnivorous," meaning that they are generalist predators feeding on other small animals or scavenging on their remains. Some, however, are "herbivorous". This is not to say that they only eat plants; rather, the bulk of their diets consist of plant-derived matter. For example, some forage on sticky fluids produced by plants to attract ants, called extra-floral nectar; others feed on the...

Symbiosis between ants and bacteria explains how leaf-cutter ants dominate tropical environments Leaf-cutter ants, which cultivate fungus for food, have many remarkable qualities. Now there's a new one to add to the list: these ant farmers, like their human counterparts, depend on nitrogen-fixing bacteria to make their gardens grow. The findings, reported this week in the journal Science, document a previously unknown symbiosis between ants and bacteria, and provide insights into how...

Student field crews study the ecological power of ants in Central America under the guidance of biologist John Longino "This work will be physically demanding. You will need to carry bulky sampling supplies into rugged terrain. Some sites may be swelteringly hot, others cold and rainy. You will need to move off trails into dense forested habitats. Long hikes may be required ... There will be mud and mosquitoes." Although a hard-labor camp could be a reasonable match for that description, in...

A wasp is any insect of the order Hymenoptera and suborder Apocrita that is not a bee, sawfly, or an ant. The less familiar suborder Symphyta includes the sawflies and wood wasps, which differ from the Apocrita by having a broad connection between the thorax and abdomen. Also, Symphyta larvae are mostly herbivorous and "caterpillarlike", whereas those of Apocrita are largely predatory or parasitic. Most familiar wasps belong to the Aculeata, a division of the Apocrita whose ovipositors are...

Spider wasps, also called pompilid wasps or spider-hunting wasps, are insects belonging to a diverse family named Pompilidae, of the order Hymenoptera. Spider wasps are sometimes distinct from other wasps in features such as eye structure (no notch as in Family Vespidae), legs modified for grooming, and in having a groove dividing the mesopleuron (a region of the thorax) into halves. Larvae can also be identified by physical examination. Females are often larger than the males, with...

Yellowjackets are typically black-and-yellow wasps of the genus Vespula or Dolichovespula (though some can be black-and-white, the most notable of these being the bald-faced hornet, Dolichovespula maculata). They are characterized mostly by their distinctive combination of black-and-yellow color, small size (slightly larger than a bee), and entirely black antennae. They live in colonies and build globular paper nests. Workers are around 12-20 mm in length, depending on species, and feed on...

Paper Wasps are social wasps and make up the genus Polistes. They form small colonies with umbrella-shaped nests in sheltered spots, and are quite mild-mannered. They feed on caterpillars and other soft-bodied insects, most of them pests. Despite the use of the proper name, most social wasps make nests from paper, although some tropical wasp species such as Listenogaster Flavolineata use mud, a far more easy resource for the wasp to collect. The larger colonial species, Yellowjackets,...
