By Booker T Leigh Tomatoes are generally easy to grow, but problems arise occasionally that can take a toll on their quality and quantity. This summer seems to be one of those years when tomatoes are a little harder to grow. The most common problems gardeners are experiencing are caused by heat, insects and disease. Blossom end rot is a common disease that affects tomatoes. The bottom of the tomato turns black when plants suffer from this disease. This problem is caused by a lack of...

By Shawna Morrison shawna.morrison@roanoke.com 381-1665 It's taken three weeks, three treatments and the removal of a hidden animal carcass, but the fleas are almost gone from the Pulaski County Courthouse. Employees there began complaining in early June that the tiny critters were all over the place, Assistant County Administrator Robert Hiss said. "They just called it the way it was," he said. "They said, 'We have fleas.' " The pests were biting employees and visitors, he said, to the...

One dose of an insecticide can kill three generations of cockroaches as they feed off of each other and transfer the poison, according to Purdue University entomologists who tested the effectiveness of a specific gel bait. It is the first time that scientists have shown that a pest control bait will remain effective when it's transferred twice after the first killing dose, said Grzegorz "Grzesiek" Buczkowski, assistant professor of entomology. Passing the insecticide from one cockroach to the...

COLLEGE PARK, Md., June 19 /PRNewswire-USNewswire/ -- Security, health and safety sensors in coal mines, buildings or underground public transit areas where air or water does not readily flow may one day be improved by research on young mayflies at the University of Maryland's A. James Clark School of Engineering. Mechanical engineers Ken Kiger and Elias Balaras and entomologist Jeffrey Shultz at the University of Maryland have identified a biological mechanism in the young mayflies that...

This Behind the Scenes article was provided to LiveScience in partnership with the National Science Foundation. Dressed in a white beekeeper suit and full face mask, I pour a small amount of ether into the exit hole of a yellow jacket nest. Too much ether might kill many of the colony inhabitants, too little might allow them enough mobility to attack me, but just the right amount should send the yellow jackets into dreamland. After a few minutes, my students and I quickly dig up the...

The creature's "Ëœpulling techniques' will be revealed in the April edition of the Royal Entomological Society's Ecological Entomology journal.In the world of armed beetles, biggest is usually best, as males often fight for mating rights and those with the largest jaws beat off the competition. However, this is not always the case with one particular species.Researchers at Okayama University in Japan have been monitoring the mating habits of large, medium and small Librodor...

Their gentle nature, large size, odd sounds and low-maintenance care have made Madagascar hissing cockroaches popular educational tools and pets for years. But the giant insects also have one unfortunate characteristic: Their hard bodies and feces are home to many mold species that could be triggering allergies in the kids and adults who handle the bugs, according to a new study.Researchers have identified 14 different types of mold on and around this species of cockroach, including several...

By Alister Doyle, Environment Correspondent OSLO (Reuters) - Worms, bacteria and beetles living below ground are part of the largest and least known trove of life on earth that could have spin-offs from farming to pharmaceuticals, a UN report said on Wednesday. "We know little of what is living below our feet...yet it is vital to sustaining life on earth," said Ahmed Djoghlaf, Executive Secretary of the UN Convention on Biological Diversity, which is hosting March 20-31 talks in Brazil....

Like humans, other animals are faced with everyday obstacles in their physical environments and must engage appropriate decision-making and motor skills to deal with them. Navigating these obstacles can involve highly complex events in mammals and other vertebrates, but in new work, researchers have employed an ingenious obstacle-based system for studying the control and structure of goal-oriented motor programs in the fruit fly Drosophila. The findings are reported in Current Biology by...

IOP -- The way termite guts process food could teach scientists how to produce pollution-free energy and help solve the world's imminent energy crisis. Speaking at the Institute of Physics conference Physics 2005 in Warwick today, Nobel laureate Steven Chu urged scientists to turn their attention to finding an environmentally friendly form of fuel. In an impassioned plea to some of the world's brightest minds, he explained how he's leading by example, and encouraged others to join the effort...

A caterpillar is the larval form of a lepidopteran (a member of the insect order comprising butterflies and moths). Caterpillars are characterized by their long segmented bodies and many sets of "legs". They eat voracious leaf eaters and grow rapidly, During growth the caterpillar will shed its skin four to five times before pupating into its adult form. Caterpillars have six true legs (being hexapods) on the thorax, up to four pairs of prolegs on the middle segments of the abdomen, and...

The Dragonfly is an insect belonging to the Order Odonata and suborder Anisoptera. It is characterized by large multi-faceted eyes, two pairs of strong transparent wings, and an elongated body. The dragonfly's diet consists typically of mosquitoes, midges and other small insects like flies, bees, and butterflies. They can be found around lakes, ponds, streams, and wetlands because their larvae (known as nymphs) are aquatic. Dragonflies do not bite or sting humans. Instead they are valued...

PHOTO CAPTION: Eriothrix rufomaculata (Photo taken by Keith Edkins) The tachinid flies (family Tachinidae) are by far the largest and most important group of insect parasitic flies, with over 1300 species in North America. It is a diverse group with some resembling drab houseflies and others brilliantly colored. All species are parasitic in the larval stage, and many are important natural enemies of major pests. Many species of tachinids have been introduced into North America from...

PHOTO CAPTION: Scanning Electron Micrograph of a Flea (photo by Centers for Disease Control and Prevention (CDC) / Janice Carr) Flea is the common name for any of the small wingless insects of the order Siphonaptera. Fleas are external parasites, living by hematophagy off the blood of mammals and birds. Some well known flea species include: Cat Flea (Ctenocephalides felis), Dog Flea (Ctenocephalides canis), Northern Rat Flea (Nosopsyllus fasciatus), Oriental Rat Flea (Xenopsylla...

PHOTO CAPTION: Goliath Beetle Beetles are one of the main groups of insects. Their order, Coleoptera (meaning "sheathed wing"), has more species than any other order in the entire animal kingdom. Forty percent of all described insect species are beetles (about 350,000 species), and new species are regularly discovered. Estimates put the total number of species at between 5 and 8 million. When J. B. S. Haldane, a British geneticist, was asked what his studies of nature revealed about...
