U.S. Department of Agriculture (USDA) scientists are showing Arizona cotton growers how to reduce their dependence on broad-spectrum insecticides by controlling sweetpotato whiteflies with greener alternatives. Some Arizona growers continue to combat whiteflies with broad-spectrum insecticides that wipe out a number of insects, despite the availability of sprays that specifically target whiteflies. Steve Naranjo, a scientist with USDA's Agricultural Research Service (ARS), and Peter...

Bed Bug Insecticide Resistance Mechanisms Identified

Bed bugs, largely absent in the U.S. since the 1950s, have returned with a hungry vengeance in the last decade in all 50 states. These insects have developed resistance to pyrethroids, one of the very few classes of insecticide used for their control. A research team at Virginia Tech has discovered some of the genetic mechanisms for the bed bug's resistance to two of the most popular pyrethroids -- deltamethrin and beta-cyfluthrin. The discoveries will accelerate efforts to understand the...

Improper use of insecticides by individuals looking to kill bedbugs resulted in 80 illnesses and one fatality over a three-year period, according to a Centers for Disease Control and Prevention (CDC) report released on Thursday. The CDC study included data from 12 states, only seven of which -- California, Florida, Michigan, New York, North Carolina, Texas and Washington -- reported illnesses that resulted from bedbug insecticides. Most of the cases originated from New York City, "the home...

When wireworms feast on potatoes, the results aren't pretty: The spuds' surfaces are left punctured, pitted and unappealing. For the past few years, U.S. Department of Agriculture (USDA) scientists and their colleagues have sought a solution in the form of spuds with genetic resistance to the worms, with special attention focused on two wild potatoes from Chile and Bolivia: Solanum berthaultii and S. etuberosum. Previous studies showed that the wild potatoes resisted Colorado potato...

Farmers who spray insecticides against aphids as a preventative measure only achieve a short-term effect with this method. In the long term, their fields will end up with even more aphids than untreated fields. This has been reported by researchers at the Biocenter of the University of Wrzburg in the scientific journal PLoS One. What's the status of the biodiversity in differently managed triticale fields? This is what the biologists at the Department of Animal Ecology & Tropical Biology...

Growth of cropland, loss of natural habitat to blame The continued growth of cropland and loss of natural habitat have increasingly simplified agricultural landscapes in the Midwest. In a study supported in part by the National Science Foundation's (NSF) Kellogg Biological Station Long-Term Ecological Research (LTER) site in Michigan--one of 26 such NSF LTER sites around the world--scientists concluded that this simplification is associated with increased crop pest abundance and insecticide...

Biocides turn out to be less toxic for the environment if they are subjected to microencapsulation, due to the fact that this process forms shell(s) for the substance. This is the conclusion of chemist Ms Mariluz Alonso in a thesis defended at the University of the Basque Country (UPV/EHU). In this research, she chose a number of biocides and other complementary substances, seeking a micro-encapsulation which, besides being compatible with the environment, is more soluble in water, more...


Word of the Day
callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
