K-State contributions to red flour beetle genome sequencing featured in March 27 issue of Nature
March 24, 2008MANHATTAN, KAN. -- Most of us hate to find the red flour beetle living happily in the flour sack in our pantries. But for several scientists at Kansas State University, and many others throughout the world, this pest of stored grain and grain products is the best organism for studying genetics.
The superior status of this beetle, Tribolium castaneum, as an experimental system is largely because of the work of two Kansas State University faculty, Susan Brown, professor of biology, and Rob Denell, university distinguished professor of biology. They worked in collaboration with Richard Beeman, research entomologist at the U.S. Department of Agriculture Grain Marketing and Production Research Center in Manhattan.
This team won funding to get Tribolium's genome sequenced, making it one of the earliest insect genomes to be sequenced and the first pest insect to be studied in this way.
"We've been able to exploit Tribolium's ease of culture, short life cycle, and facile genetics to create an array of sophisticated methodologies," Denell said. "It now joins the fruit fly Drosophila as a premier insect genetic system, and even offers advantages in some areas of study."
The journal Nature will publish an article March 27 announcing the sequencing of the beetle's genetic material and summarizing the implications of this work.
"It's really exciting to see the burst of activity in Tribolium studies that has accompanied the sequencing project," Brown said. "This new information will greatly aid research on topics as diverse as insect pest management and the genetic control of development."

The flourbeetle's genome sequenced for the first time
An international research consortium with the participation of a research team led by Professor Cornelis Grimmelikhuijzen from the Department of Biology, has sequenced the genome from the red flour beetle Tribolium castaneum.
New genetic analysis forces re-draw of insect family tree
The family tree covering almost half the animal species on the planet has been re-drawn following a genetic analysis which has revealed new relationships between four major groups of insects.
K-State professors discover enzyme responsible for creation of a beetle's hard shell
Kansas State University researchers think their discovery of the enzyme involved in the hardening of a beetle's exoskeleton or cuticle could lead not only to better pest control, but also help create similar strong, lightweight materials for use in aircraft and armor.

Description: Increasing levels of inhibitors that target cysteine and/or serine proteinases were fed to Tribolium castaneum larvae, and the properties of digestive proteinases were compared in vitro. Cysteine proteinases were the major digestive proteinase class in control larvae, and serine proteinase activity was minor. Dietary serine proteinase inhibitors had minimal effects on either the developmental time or proteolytic activity of T. castaneum larvae. However, when larvae ingested cysteine... |

Perma-Guard DE Fossil Shell Flour 1 lb bag by Perma-Guard This is Perma-Guard brand, Diatomaceous Earth, Fossil Shell Flour, and contains less than 1/2% crystalline silica. DE can be used to control cockroaches, bed bugs, slugs, aphids, earwigs, silverfish, ants, adult flea beetles, lice, mites, and many other insects. Sprinkle it in the garden, on the grass, and around the foundation of your house. Use inside on pantry shelves, under sinks, closets, on rugs, and in corners and crevices. We ONLY carry the Diatomaceous Earth that is made for pest control. Insects cannot become immune to it, because it's a mechanical insect killer, not a chemical. Insects come in contact with this powder and die of dehydration within 48 hours. Safe for use in kitchens, on carpets and in the area where your pet sleeps. Diatomaceous earth has been used in Asia to... |

Carbonic anhydrase metabolism is a key factor in the toxicity of CO"2 and COS but not CS"2 toward the flour beetle Tribolium castaneum [Coleoptera: Tenebrionidae] ... Biochemistry and Physiology, Part C] by V.S. Haritos (Author), G. Dojchinov (Author) This digital document is a journal article from Comparative Biochemistry and Physiology, Part C, published by Elsevier in 2005. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser. Description: The analogues carbon dioxide (CO"2), carbonyl sulfide (COS) and carbon disulfide (CS"2) have been useful as substrate probes for enzyme activities. Here we explored the affinity of the enzyme carbonic anhydrase for its natural substrate CO"2, as well as COS and CS"2 (1) by in vitro kinetic metabolism studies using pure enzyme and (2) through mortality bioassay of insects exposed to toxic levels of each of the gases during carbonic anhydrase inhibition. Hydrolysis of COS to form hydrogen... |
